I LIKE THE IDEA OF USING MARKUS TO GO THROUGH AND PURCHASE PROPERTY IN AMERICA, IT WOULD SUIT NATHANS GOALS WELL. AS FOR HAVING AN ALL PURPOSE CURE, ILL HAVE TO BE CAREFUL ABOUT THAT BUT IN THE FUTURE SOMETHING LIKE THAT COULD MAKE HIM INVALUABLE TO INTERESTED PARTIES. ILL GIVE IT SOME THOUGHT.
ONTO THE CHAPTER FRIENDS
...
Night settled over the outer settlement slowly enough that Nathan was able to watch the last remaining colour drain from the marsh before he finally allowed himself to lie down. The change came by degrees, too gradual for any one moment to be called the beginning of darkness. For a while the western sky remained bruised red between the limestone ridges, and that colour lay broken across the blackening channels in long trembling strips whenever a canoe passed beneath the raised walkways or somebody leaned over a platform to draw water. Then the red thinned to copper, copper went grey, and the water began reflecting the village fires instead, little wavering pieces of orange suspended between reeds and timber posts as though a second settlement had been drowned beneath the first. The Ndipaya seemed to possess nothing comparable to the hard division between day and evening the British expedition had carried into the country with watches, scheduled meals and men assigned to sentry duty according to little columns written on paper. Work simply diminished as darkness made certain tasks inconvenient and replaced them with others. Fishing vessels returned through the channels while there was still enough light to recognise faces from a distance; nets were dragged across damp boards, catches sorted beneath low voices, children collected from places where they had been allowed to wander during daylight and brought closer to occupied platforms.
Cooking fires brightened as the marsh went black around them, and conversations which had carried freely across the water through the afternoon became softer without ever disappearing. Somewhere nearer the limestone a drum sounded several times, its slow rhythm travelling outward over the reeds, then stopped and did not begin again.
Nathan could hear hunters talking farther along the settlement, their conversation occasionally interrupted by the hollow knock of bare feet or wooden spear shafts against the walkways, while the British portion of the expedition gradually reduced itself to a handful of guards and exhausted scientists trying to organise notes taken in a place none of them had expected to exist when they left England.
Harcourt lasted longest. Even after Nathan told him for the second time that whatever had survived three thousand years beneath the mountain could survive until morning without being redrawn, the archaeologist remained beneath one of the borrowed lamps with his notebook spread across both knees, attempting to reconstruct a section of the underground city from memory because, as he had explained with increasingly tired conviction, he did not trust sleep not to rearrange it. The first version had been careful. The second became more ambitious. By the third, one staircase had acquired two additional terraces and Harcourt had begun arguing quietly with himself over whether a distant wall had contained a doorway or merely a break in the masonry. Bell sat nearby pretending not to watch, his own geological notes already closed, until Harcourt drew the same flight of steps twice on adjacent pages and gave them different proportions. Only then did the geologist lean over, remove the pencil neatly from between Harcourt's fingers and place it behind his own ear.
"You've drawn that staircase twice," Bell said, and the archaeologist turned toward him with the affronted stare of a man whose property had been stolen in front of witnesses. Bell tapped the two pages before Harcourt could protest, then pointed to one sketch and the other.
"This one has six visible tiers. That one has eight. Either the ancient builders are still working while we sleep or you are no longer a reliable witness."
"I am trying to preserve the impression before familiarity makes it smaller," Harcourt replied, rubbing one thumb against his brow while he stared at the drawings as though hoping one would confess. Fatigue had reddened the edges of his eyes and made his spectacles slide farther down his nose each time he bent his head. "By morning I will remember it as a ruin. Tonight I still remember what it was like to walk into the chamber and realise the bloody thing kept going."
"Then stop while you still remember it accurately," Nathan said, and Harcourt looked up to find him standing beside the lamp with his arms folded. Nathan nodded toward Bell's ear, where the confiscated pencil remained safely out of reach. "You have now reached the point at which archaeology is being conducted by exhaustion. Anything else you add tonight will be a collaboration between you and whatever your brain invents after midnight."
Harcourt stared at him for several seconds, then looked back at the notebook. Whatever argument he had prepared seemed to fade when he compared the two staircases again. "I dislike both of you."
"That is encouraging," Nathan replied while Bell handed the notebook back but retained the pencil. "It suggests sufficient cognitive function remains for irritation. Go to sleep."
Harcourt finally surrendered, though not gracefully. He spent another minute arranging the notebook where no one could accidentally place a cup upon it, warned Bell twice that grease from the pencil would damage nothing and then disappeared beneath the shelter assigned to the scientists while still muttering about perspective. Bell followed less than twenty minutes later. Wetherby had gone down considerably earlier, his resistance broken not by Nathan but by his own inability to finish a sentence about pale vegetation growing beneath reflected sunlight. He had spent supper trying to decide whether several underground species represented adaptations to low light, mineral chemistry or some combination of both, and by the end he was speaking in fragments about chlorophyll while staring into an empty cup.
His specimen envelopes remained untouched in his case, because the elder's restrictions had been obeyed despite the almost physical distress this appeared to cause him. Nathan had watched the botanist stand over a pale flowering plant for nearly a minute that afternoon, fingers twitching once toward the collection wallet before he sighed, took out his notebook instead and began drawing every visible vein in the leaves. The result had probably been more useful than whatever crushed specimen he would have carried back to Britain, though Nathan had refrained from saying so because congratulating Wetherby would have invited another argument about methodology.
T remained awake after the scientists disappeared. Nathan saw the dark Ledermaske pass beyond his shelter twice while the settlement settled around them, first when T inspected the British positions and again after the Ndipaya hunters changed their own watch. The Winchester remained against his chest, its outline catching a thin strip of firelight whenever he crossed one of the larger platforms before darkness swallowed him again. The previous day's encounter with the red creature had changed the way several British soldiers regarded the tree line, and T appeared no more willing than they were to assume that something capable of surviving a shotgun blast and vanishing after a grenade had conveniently died somewhere out of sight. The men who had actually taken part in the hunt were quieter about it than those who had only heard the story. They did not argue over how tall the creature had been or speculate loudly about whether it possessed antlers, bone, horns or branches. They simply looked at the trees differently. Every unmoving trunk beyond the fires received an extra glance. One sentry spent so long watching a crooked tree across a channel that another man finally asked what he had seen there, and the first soldier answered that he had seen nothing, which was precisely why he was still looking.
Nathan encouraged the caution without making a point of it. The thing they feared had disappeared, not been accounted for, and nobody needed Professor Drake telling them that uncertainty was healthy while their nerves were already doing the job for him. By the time T passed the shelter on his second circuit, most of the expedition had become quiet enough that Nathan could distinguish the village sounds around them: frogs clicking beneath the walkways, insects working continuously in the reeds, somebody farther away coughing twice before settling, water touching the timber supports with the patient rhythm of something that had done so long before any of them arrived. The ordinary life of the marsh was almost offensively reassuring after what the forest had shown them.
Nathan eventually stretched beneath the canvas allocated to him and closed his eyes. His coat lay folded within reach, boots positioned where one hand could find them in darkness, and there was nothing unusual about the way one arm rested loosely across his body while his breathing slowed. The human vessel entered genuine rest with surprising ease. Muscles relaxed. Warm humid air pressed against his face. Smoke from the dying fires drifted through the open edge of the shelter in occasional thin traces, and the village sounds softened as fatigue altered his attention. For several minutes he allowed himself to occupy both states at once: the body lying beneath canvas and another piece of himself waiting far below the mountain beside an underground channel. It remained one of the stranger consequences of what he had become, not the simple experience of looking through two sets of eyes but a more fundamental division of scale, anatomy and sensation.
His human chest rose while another portion possessed neither lungs nor chest; his skin registered warmth while the distant fragment knew temperature as gradients crossing a membrane; one body heard frogs and muted conversation while the other interpreted the tremor of water against stone.
The overlap became irritating long before it became painful. Nathan narrowed his attention deliberately and allowed the body beneath the shelter to continue sleeping without him attending to every breath. The marsh receded slowly rather than vanishing at once. Warmth went first, then the weight of cloth across his chest, then the smell of smoke. Frogs beneath the village platforms became faint and oddly stretched, as though heard down a corridor of impossible length, until they too disappeared and another world assembled itself from colder information.
Stone pressed against him. Water moved nearby, its passage through a narrow subterranean channel producing delicate vibration long before anything resembling sound reached the tiny body that had been waiting beside it. Nathan's consciousness gathered fully inside the fragment he had released into the forbidden district earlier that day, and however often he had experimented with separated biomass, the transition remained disorienting because so few of the structures by which a human mind understood existence were available. There was no pulse beneath his awareness, no breath providing rhythm, no inner ear deciding which direction was down and no pair of eyes quietly performing the enormous labour of converting light into depth and distance. The little mass of Red-Light had spent hours attached beneath a fine root near the water, maintaining itself with minimal attention while Nathan walked above with the elder and scientists. Now, fully inhabited, it presented the passage through senses built entirely for usefulness rather than familiarity.
Stone became texture, pressure and the manner in which vibration travelled through different densities. Water announced itself not as a shining surface but as movement transmitted through rock and air, a complex sequence of tiny disturbances that told Nathan where it narrowed, where droplets fell into it and where something small had crossed moments earlier. Temperature moved through him as gradients rather than warmth against skin. Chemical traces drifting in the damp became almost tactile when Red-Light concentrated upon them, and the life hidden around him crowded the environment in ways his human body would never have noticed. A mite moving across the root above became a sequence of delicate pressures. Something many-legged shifted beneath a thin plate of mineral and remained still when another creature approached. Fungal growths spread through wet cracks, feeding on material so old and small that no human explorer would have considered the passage occupied at all.
Nathan released the root.
The fragment dropped onto wet limestone and remained there for a moment as little more than a narrow reddish-black strip, sufficiently shapeless that any passing creature might have mistaken it for plant matter or something dead carried there by the water. Then Red-Light redistributed itself. The ribbon thickened at several points, crude appendages pressing beneath its length until they found purchase against the irregular stone. They were ugly little structures, created without concern for symmetry or permanence, but when Nathan pulled forward they dragged him successfully out of the shallow channel.
He crawled.
At that scale the abandoned passage was crowded. Pale insects hid beneath mineral crusts. Small beetles travelled between patches of fungus feeding upon accumulated decay. Fine roots descended from fissures in the ceiling and crossed the stone like enormous rope systems, their damp surfaces serving as roads for animals whose entire territory occupied less space than Nathan's human hand. Drops of water which would have been beneath notice above became events large enough to reshape little pools or wash insects from one ledge to another. Generations of Ndipaya might have avoided this part of the mountain for close to a century, but the absence of people had not produced emptiness. It had simply removed one scale of life and allowed all the others to continue without being observed.
None of them knew what Nathan was.
That suited him.
The fragment possessed no silhouette their instincts had evolved to classify and no familiar chemical signature announcing predator or prey. A beetle passed within inches of him without altering course. Something segmented retreated beneath a stone only when Nathan's movement disturbed the surface directly beside it, and even then the response was to the disturbance rather than recognition.
The scorpion approached for the opposite reason. It had no inherited warning associated with the shapeless thing on the limestone and therefore treated it as potential food.
Nathan detected the animal before he understood what produced the sensation. Light contacts moved through the stone ahead in an ordered rhythm distinguishable from falling water or the more frantic movements of smaller insects. The contacts paused, resumed and approached. Nathan flattened himself instinctively, the improvised appendages dissolving back into his underside until he looked even less alive.
A scorpion emerged from beneath an overhanging shard of limestone. From a human perspective it would have been small enough to vanish beneath Nathan's palm. From the level of the fragment it arrived like armour given legs, dark claws held open in front while the tail curved above the abdomen with the quiet readiness of an animal whose entire survival depended upon acting before something larger acted upon it.
The scorpion stopped over him.
Nathan remained still.
The animal investigated in ways human vision would have overlooked entirely, adjusting its stance as sensory structures sampled vibration, air movement and chemical trace. One claw edged closer. The tail shifted minutely. Nathan had no particular reason to consume the creature and intended to let it pass once curiosity faded.
The fragment moved by barely a fraction as water trembled along the stone.
The scorpion struck.
Its tail snapped forward with a speed the tiny shape Nathan occupied could not have evaded naturally. The stinger entered Red-Light and delivered venom into tissue that had never needed to evolve any defence against it. For a fraction of a second Nathan felt the chemistry begin its work, molecules interfering with structures which, in ordinary flesh, would have translated into paralysis or death.
Red-Light identified the intrusion almost immediately.
The shapeless fragment closed around the stinger.
The scorpion recoiled, but the body beneath it had ceased preserving any pretence of helplessness. Red-black filaments climbed the stinger and multiplied around the first tail segment before the animal could withdraw. One strand caught a rear leg, another slipped beneath the abdomen and entered the narrow seam between two plates. The scorpion twisted violently, claws opening and closing against empty air while the mass spread over its exoskeleton.
The change from prey into attacker happened too quickly for the animal's nervous system to contain any concept for it. It fought because fighting was the only available response. The tail struck again and again into living tissue already climbing it. Venom entered a body which adjusted more rapidly than toxin could disrupt it. Legs scraped across limestone, producing vibrations frantic enough that several smaller creatures nearby fled into cracks. One claw found a tendril and sheared it cleanly, only for the severed piece to contract back toward the mass while two more filaments reached the joint beneath.
Nathan enclosed the scorpion.
Consumption at that scale lacked the spectacle associated with taking something human-sized, but the absence of spectacle made it no less complete. The animal disappeared section by section beneath living tissue. Plates of exoskeleton were sampled, broken down and catalogued.
Muscle, nerve, venom apparatus and the minute sensory structures Red-Light had lacked moments earlier passed into Nathan's understanding. Its legs continued moving after much of the animal had ceased to exist independently, motor signals persisting through remaining nervous tissue until those structures too dissolved into him.
Then Nathan contracted.
Nothing remained upon the limestone except Red-Light.
The new information arrived more cleanly than a human life ever did. A human being came with decades of faces, memories, language, relationships and contradictions tangled together so tightly that consuming one meant receiving a world. The scorpion possessed no story of itself. Its experience consisted of repeated associations tied to hunger, danger, temperature, shelter and reproduction, yet within those limits the information was astonishingly precise.
A dark cavity was safety. Certain vibrations meant prey. A particular heat gradient meant retreat. The water's edge produced insects but exposed the body to larger predators. Heavy pressure through stone meant something far too large to challenge. Other scorpions could mean threat, opportunity or mating depending upon chemical state and size. The animal's entire range might have occupied one corner of the forgotten passage, but it knew that territory with an intimacy no surveyor could have matched. Nathan inherited the limestone flake beneath which it sheltered, the narrow fissure leading toward a fungal feeding patch, the safe route to water and several regions marked not by any conceptual explanation but by avoidance.
One association differed sharply from the others.
Fear.
Not the automatic aversion produced by centipedes, large predators or repeated injury. This fear had been learned. Something familiar had ceased behaving in a familiar way, and the scorpion's primitive nervous system had remembered the contradiction strongly enough to reorganise its movement around it.
Another scorpion.
Nathan followed the fragments carefully.
There had been two animals. The first was the one now inside him, an ordinary scorpion whose body and fragmentary experience Nathan had just assimilated. The second lived farther through the limestone and occasionally crossed into the first animal's hunting range. Their early encounters were unremarkable: raised claws, poised tails, short advances and retreats governed by size, hunger and whether either individual considered injury worth the contested ground.
Then the second scorpion changed.
The memory offered no clear image, because the first animal had not perceived the world in any form Nathan could simply replay as sight, but sensation preserved enough. The second scorpion's stride lost its familiar rhythm. Its abdomen enlarged. Plates which once sat tightly against one another separated at their seams, and black material sometimes appeared between them before disappearing again. Its chemical trace still identified the same animal and yet carried something else, some additional presence the ordinary scorpion eventually associated more strongly with danger than with its own species.
In one remembered encounter the first scorpion had approached too closely.
The second animal opened.
Thin black tendrils erupted from beneath its abdominal plates, struck the limestone and dragged the scorpion forward with an acceleration its natural legs could never have produced. One filament touched the fleeing animal before it reached a crack narrow enough to escape.
The contact had lasted perhaps less than a second.
The fear remained.
Afterward the scorpion Nathan consumed avoided that entire region whenever the altered animal's scent was present. Routes once used for hunting were abandoned. A feeding patch rich enough to attract repeated visits became something approached only from one side. The ordinary creature had built its little life around the presence of an infected neighbour without ever possessing a concept for infection.
Nathan went very still within the borrowed memory.
This was not a vague warning from some direction deeper beneath the city. The first scorpion had known the second directly. It knew where the altered animal hunted, where it crossed into familiar territory and which passages carried its chemical trace.
Nathan now knew the same.
The little mass began changing again.
This time Red-Light reproduced rather than improvised. An exoskeleton formed over the biomass and darkened as it hardened into segmented plates. Eight legs extended beneath the contracting body and found the positions encoded in the anatomy Nathan had just assimilated. Claws formed at the front. The abdomen narrowed behind them and continued into articulated tail segments, each one locking into place before the next developed. Nathan formed the venom apparatus and stinger last, not because he expected to need them but because omitting useful biological equipment merely for simplicity offended him.
When the transformation finished, a scorpion stood where the shapeless fragment had been.
Nathan attempted to move.
One leg advanced. Then another. Two limbs on the opposite side responded late, and the body lurched sideways with enough clumsiness to irritate him immediately. Eight-legged locomotion did not translate naturally from the expectations of a human brain, and trying to issue conscious instructions to every limb made the shape less capable than the actual animal had been.
Nathan stopped trying to walk like Nathan Drake.
He allowed the consumed nervous patterns to guide the body below conscious thought.
The effect was immediate. Eight limbs ceased being eight separate instructions and became one fluid gait, the body crossing damp stone with the low rapid precision of an animal that had spent every moment of its existence navigating exactly this scale. The tail balanced turns automatically. Claws tested uncertain surfaces without interrupting forward movement. When Nathan crossed loose mineral fragments, the copied body adjusted before he consciously registered the change.
More useful than speed was the map.
The dead scorpion understood no miles, yards or compass directions. Its territory existed as sequences tied to landmark and sensation: leave shelter, pass the raised mineral seam, cross the damp depression, follow the root until it divides, avoid the narrow crack occupied by something dangerous. As Nathan encountered each feature the next association surfaced, allowing him to move through a country measured in inches and feet with the certainty of an animal which had travelled the same paths hundreds of times.
He was hunting now, and the distinction from exploration sharpened his attention. Somewhere ahead lived the second scorpion, the infected one, and Nathan wanted it intact long enough to watch.
The copied body carried him through the narrow passage far more quickly than the wormlike fragment ever could. Beetles fled when the scorpion approached. Smaller arthropods froze against stone or vanished into crevices. Their responses confirmed that the disguise reached deeper than appearance; whatever chemical and mechanical cues their instincts used accepted Nathan as the animal he resembled.
The first feeding patch appeared exactly where memory placed it, pale fungus spreading beneath a damp root and attracting several small beetles. The consumed scorpion's nervous architecture produced a feeding response so automatic that Nathan felt the body angle toward them before he consciously corrected course.
He ignored the insects.
The other scorpion mattered more.
Beyond the feeding patch the route passed beneath a low plate of limestone and entered territory the first animal had increasingly avoided. Familiarity thinned there, though several markers remained: a dry hollow, a ridge of mineral deposit, a narrow fissure where the infected scorpion's scent had once been strongest. Moisture increased beneath one section before vanishing almost completely along another. Fine roots grew denser overhead, some carrying dark blemishes which did not resemble ordinary rot. Nathan paused at one and touched it with the edge of a claw, allowing microscopic material to transfer onto his copied shell.
Red-Light sampled.
Unusual compounds. Organic. Too little context.
He moved on.
The dead scorpion's memory surfaced sharply when Nathan reached a split in the passage. The left route returned toward familiar hunting ground. The right belonged to the other one.
Nathan turned right.
The little corridor descended beneath several limestone fragments stacked by geological accident, and at his present scale each change in elevation felt exaggerated. A drop of several inches became a ledge requiring careful placement of the front claws before the hind legs followed. Water noise diminished behind him until only vibration remained.
Then something moved ahead.
Nathan stopped.
Three light contacts passed through the stone.
A pause.
One more.
Dragging.
Then several impacts in quick succession.
He lowered his copied body until the underside almost touched the floor.
Nothing appeared.
Chemical traces reached the sensory structures distributed across his shell, and the dead animal's fear arrived before Nathan consciously interpreted why.
Same species.
Wrong individual.
The infected scorpion was nearby.
Nathan advanced slowly along the mineral ridge until the passage opened into a broader cavity where fungal strands clung to the low ceiling and a shallow pool occupied one side. The consumed animal recognised the place only faintly. It had hunted there before the infection worsened and avoided it almost completely afterward.
Nathan stopped behind a flake of limestone.
Movement continued beyond.
The infected scorpion was hunting.
Nathan remained hidden and listened through the stone. The rhythm moved several inches, stopped, moved again and then accelerated. Another set of vibrations became frantic beneath it.
Something had been caught.
Nathan eased around the stone.
The second scorpion stood perhaps eighteen inches away.
At first the sight almost disappointed him.
It looked ordinary.
Slightly larger than the body he inhabited, perhaps, but nothing in its silhouette justified the terror preserved inside the first animal's nervous system. Its claws held a beetle against the floor while the tail curved above it exactly as Nathan would have expected of any predatory scorpion.
Then he noticed the stinger remained unused.
The beetle struggled.
The scorpion's abdomen twitched.
One plate lifted.
A strand of black tissue pushed through the gap.
Nathan became absolutely still.
The filament extended until it reached the beetle, curved around its thorax and tightened. A second emerged from another seam. Then a third. The beetle convulsed as the tendrils worked between its plates, and its struggling weakened with astonishing speed. Tissue began disappearing from places untouched by any recognisable mouth, drawn inward through black strands which flexed and thickened as they fed.
The infected scorpion swelled.
Its abdomen enlarged fractionally while the prey collapsed. The process lasted less than ten seconds. When the tendrils withdrew and the claws released, only broken shell remained on the stone.
Nathan's scientific interest sharpened into something almost predatory in its own right.
The second scorpion was not an ordinary animal distorted by the first one's limited perception. It was infected. Changed. Something living inside it could consume biological material directly and return that material to the host.
The scorpion shuddered once after feeding.
One claw flexed.
The joint swelled.
A narrow seam opened along the outer shell and black tissue filled the space beneath it, supporting the growing limb before the edges hardened. When the claw moved again it was only fractionally larger, a change subtle enough that anyone without Nathan's attention might have missed it.
He watched.
Consumption followed by structural alteration.
The resemblance to Red-Light was immediate enough to be uncomfortable and different enough to become fascinating.
Whatever lived inside the scorpion did not appear to replace its host as Nathan could. The original arthropod anatomy remained clearly present. The animal still hunted according to instincts recognisably its own until the black structures became useful, at which point the infection supplemented the host rather than simply imitating it.
Nathan wanted the scorpion.
Not the empty shell afterward. Not merely the path it had followed. Not another trace from the river.
He wanted the thing inside it.
For the first time since entering the deeper Ndipaya territory he had direct biological evidence of whatever was changing life under the mountain, and it could be observed alive.
The infected scorpion finished feeding and turned.
Nathan remained motionless.
The two animals faced one another across the little hollow. The second scorpion raised its claws, and for a heartbeat the scene looked so ordinary that the dead animal's inherited responses activated automatically inside Nathan's copied nervous architecture.
Threat display.
Tail ready.
Assess size.
Advance or withdraw.
Nathan ignored the impulse.
The infected animal did not follow it either.
Its claws lowered.
Its tail remained raised.
The abdomen contracted.
Black tendrils slipped from beneath the plates and touched the stone.
Nathan stepped backward once.
The other scorpion followed.
He moved sideways.
It corrected immediately.
Nathan stopped.
The infected creature stopped as well.
That caught his attention.
It was not simply defending territory. It was tracking him.
Nathan moved again. The black filaments changed orientation before the animal's legs did, several pressing into the stone as though sensory information passed through the infection independently of the host's ordinary organs.
Nathan allowed it closer.
The scorpion advanced perhaps six inches before its body convulsed violently enough that one leg left the floor. The abdomen swelled. Black tissue pushed between three plates at once, bulged and tightened again. The tail jerked sideways and struck limestone hard enough to chip the surface.
The first scorpion had remembered this, not with understanding but with enough accuracy that Nathan recognised the same pattern.
Then the infected animal rushed him.
It crossed the remaining distance far faster than ordinary scorpion anatomy should have permitted. Black tendrils struck the stone ahead of the legs, attached and contracted. The entire body shot forward in a brutal little lurch.
Nathan moved.
The copied scorpion turned and sprinted around the mineral ridge.
The infected one followed.
Nathan had no intention of escaping.
He was measuring it.
The dead scorpion had fled from this animal before, and Nathan deliberately took the same route because he wanted to compare memory with behaviour. Behind him came the exact rhythm preserved in those fragments.
Normal footfalls.
Tendril contact.
Drag.
Acceleration.
Footfalls.
Drag.
Acceleration.
Nathan increased speed.
So did the pursuer.
The narrow crack appeared ahead, the same one the ordinary scorpion had used during a previous encounter. Nathan slipped through easily and stopped several inches beyond.
The infected scorpion reached the entrance and struck stone.
Its claws fit.
The abdomen did not.
For a moment it appeared trapped by the simplest law of anatomy: a body cannot pass through a space narrower than its armour.
Black filaments emerged.
They spread along both walls of the crack and gripped.
The scorpion compressed.
Nathan watched the exoskeletal plates shift over one another while tissue underneath redistributed itself, withdrawing from some sections and bulging into others. The abdomen narrowed beyond anything the shell should have allowed.
The animal forced itself through.
Once clear, its body expanded again.
Nathan remained still a fraction longer than safety recommended because the sight deserved observation.
The creature lunged.
He ran.
This time he abandoned the original scorpion's escape route. The first animal's memories had already provided confirmation, location and behavioural comparison. Nathan wanted something different now: to know how far the infected creature would follow if drawn away from familiar territory, whether pursuit outweighed territorial instinct and whether its strange biology changed behaviour once environment became unfamiliar.
It followed without hesitation.
Nathan crossed a dry shelf the first scorpion had never visited, climbed a ridge of crystalline mineral and descended into a shallow channel carved by intermittent water. The infected animal remained behind him, sometimes using its ordinary legs and sometimes throwing black filaments ahead to haul itself forward with sudden bursts that repeatedly reduced the distance.
Nathan turned abruptly behind an outcropping.
The pursuer overshot.
It stopped.
For perhaps a second nothing moved.
Then one black tendril touched the ground.
Another extended toward the route Nathan had taken.
The body followed.
Vibration, chemical residue or some additional distributed sense in the infection itself. Nathan could not yet tell which.
The uncertainty pleased him.
He moved again.
The copied scorpion body performed beautifully once Nathan stopped interfering with its locomotion. Eight legs found purchase before conscious thought required them. The tail counterbalanced every turn. Small claws tested unstable stone while the body continued forward.
Behind him the infected scorpion kept coming.
Nathan could have turned on it.
He did not.
Not yet.
Every second of pursuit produced information that consumption would end. He wanted to know where the host stopped and the infection began, whether injury provoked further structural alteration and whether the organism actively sought biological matter or merely responded when opportunity presented itself.
Most of all, he wanted the origin.
The first scorpion remembered the second changing but had no memory of why.
The answer therefore lay outside the first animal's territory.
Nathan slowed just enough to allow the infected scorpion to close, then rounded another projection of rock and paused where several routes diverged. The creature appeared behind him and chose its approach without hesitation. Nathan moved again, this time selecting the path only after seeing how confidently the pursuer entered it.
He was no longer simply leading the infected scorpion away.
He was allowing its familiarity to betray its territory.
The deeper route began taking shape through repetition. Fine roots grew more common. Several carried the same black discoloration Nathan had sampled nearer the river. Warmth increased subtly. Organic traces in the air became richer. At certain junctions the infected scorpion moved with immediate certainty, while at others it hesitated and searched before continuing.
Nathan let those differences guide him.
The narrow passage widened gradually into forgotten portions of the old city, first through broken drains and collapsed foundations and then through entire abandoned chambers where architecture had surrendered so thoroughly to water and vegetation that ruin and cave became difficult to separate. Roots split ancient masonry. Pale vines descended through fractures overhead and hung along walls no human hand had touched in generations. Reeds grew wherever subterranean water spread shallowly across old floors, and beneath them accumulated the slow debris of decades: insects, shed skins, dead vegetation, drowned animals and organic matter nobody living above had possessed reason to remove.
Nathan recognised the opportunity immediately.
Mass.
Nothing substantial in one place.
Enough in total.
The copied scorpion stopped beside a tangle of pale roots where several dead beetles lay in damp sediment. Its shell loosened. Red-black filaments emerged beneath the abdomen and covered the nearest beetle, then another. A drowned insect vanished from the water's edge. The half-decayed body of something small and reptilian lay wedged beneath a stone, and Red-Light entered it, salvaged what remained useful and left almost nothing behind.
Nathan reached the living roots.
They resisted differently from carrion but not meaningfully. Thin tendrils entered the damp outer tissue and drew biomass without destroying the entire plant. Several inches of vine shrivelled while the copied abdomen broadened. Reeds in the shallow water lost portions of their lower stems. Fungal mats thinned along their edges.
Nathan moved while he fed.
The scorpion grew gradually enough that no single moment contained a transformation dramatic enough to call complete. The legs thickened first. Exoskeletal plates separated and were replaced by larger sections even before the old shell finished splitting. Claws became heavier. Joints reinforced themselves. Nathan discarded internal arrangements an ordinary arthropod required and built only what benefited movement, leverage, sensation and structural strength. Muscle appeared where force mattered. Red-Light occupied spaces nature would have reserved for organs he no longer needed.
The body continued resembling a scorpion because the form remained useful, not because Nathan felt any obligation to preserve the animal he had consumed.
By the time he crossed the next ruined chamber he had become several times larger than the creature whose memories first carried him there.
The additional size made him faster.
Longer legs propelled the body across gaps the original scorpion would have needed to climb. Pincers occasionally struck the ground as extra supports during sharp turns. Nathan thickened the base of the tail until it functioned as a muscular counterweight, shifting his direction halfway through a leap. Sensory structures copied from the original animal multiplied along the underside and legs until vibration crossed him with almost uncomfortable clarity.
The ruins became a map made through touch.
Water flowed beneath sections of floor.
Something small fled through reeds twenty feet away.
A fractured wall settled under its own weight.
And through all of it ran the chemical residue of the infected scorpion.
Nathan began thinking of it as black.
The trace possessed no literal colour to his borrowed senses. It was a pattern of compounds, pressure history and living residue, yet black was how his mind rendered it because the signature felt wrong beside the ordinary chemistry around it, an invasive darkness impressed upon every surface the altered creature had touched.
The trail climbed.
Nathan followed.
The forgotten district had once belonged unmistakably to the city rather than the natural cave. Broken terraces rose from sediment. Stairs disappeared beneath root systems and returned several yards later, their centres worn nearly smooth by feet dead for centuries. A collapsed arch leaned over one avenue, one side swallowed beneath pale mineral growth while blocks above remained locked together by weight and the stubbornness of old construction. Roofless rooms opened behind it, reeds growing from former floors and roots descending through empty windows.
Nathan crossed them at speed.
Instead of circling one surviving building, he climbed the exterior wall. Enlarged legs found tiny irregularities in the masonry while his tail balanced the body behind. Halfway up, an ancient block broke beneath one foot and fell away into darkness. Nathan transferred his weight before the surrounding stones could follow, crossed the vertical surface and pulled himself onto the roof.
The chemical trace intensified.
He lowered himself close to the stone.
There.
The infected animal had crossed this place repeatedly.
Not merely passed once.
Nathan found residue on the outer ledge, across the remains of a carved parapet and beneath a stone projection where something large had rubbed against the masonry. One dark smear had dried between two blocks.
He touched it with the edge of a pincer.
Red-Light sampled.
Biological material.
Scorpion tissue.
Foreign organism.
Nathan withdrew before the absorbed quantity could establish meaningful contact. Even that minute sample confirmed the conclusion.
The infected scorpion had grown.
Substantially.
The animal feeding upon a beetle earlier could not have left a mark at this height or of this volume.
Nathan followed the trail across the far side of the roof. His enlarged body cleared the broken parapet in one leap and landed upon a lower structure hard enough to crack mineral crust from the old stones. He descended through a courtyard where shallow water covered part of the paving. Something alive slipped through reeds. Nathan ignored it. A rodentlike corpse lay half submerged beside one wall, decayed enough that little remained, but Red-Light stripped the useful material without slowing and distributed the additional mass through his legs and armour.
Signs of the infected animal became increasingly physical.
Reeds were flattened beneath a weight no ordinary scorpion possessed. Deep gouges marked one wall where something hard had climbed. Near another building lay a small animal almost completely hollowed, its skin collapsed around bones cleaned strangely from within.
Nathan slowed.
The city seemed to narrow despite the spaces growing larger, not because walls moved closer but because every mark around him belonged to something enormous which remained out of sight.
The sensation of being watched emerged before any watcher knew he existed.
Nathan found it more interesting than frightening.
The old avenue curved around a massive stone platform whose upper level had once carried a structure now reduced to a forest of broken pillars. Black residue passed between them so heavily concentrated that the scorpion's borrowed senses nearly recoiled from it.
Nathan climbed.
One tier.
Then another.
He crossed beneath two leaning stones and emerged onto the upper platform.
For several seconds the space looked empty.
Then part of the ruin moved.
Nathan stopped.
The infected scorpion sat beside a low building.
The word scorpion had become inadequate, though the ancestral shape remained recognisable enough to make every alteration more grotesque. Claws still occupied the front. A segmented body stretched behind. A tail—or what had once been a tail—rose over the abdomen.
Everything else had been rewritten.
The creature stood almost as large as the stone building beside it. Its exoskeleton had darkened until almost no natural coloration remained, the shell appearing black beneath the weak mineral light of the abandoned city. Armour overlapped across the abdomen in uneven layers, some plates recognisable as enlarged versions of the original anatomy and others grown afterward in heavy irregular sections that looked like armour hammered over armour without any concern for symmetry.
One side of the animal rose higher than the other because the left pincer had become monstrous.
The swollen joint supporting it looked almost capable of lifting the animal by itself. The claw opened slowly and closed again, edges no longer smooth but ridged with black growth where earlier shell had fractured and been replaced.
The opposite pincer remained far smaller.
Not weak.
Simply neglected by whatever process had rewarded the other.
Nathan remained motionless.
The tail bothered him more.
There were two.
The original segmented structure had divided above the abdomen, separating into distinct articulated tails which curved in different directions. One retained a recognisable scorpion stinger despite its grotesque size. The second had lengthened and narrowed, ending in a warped black hook around which tendrils moved constantly.
Those tendrils were everywhere once Nathan noticed them.
They flowed between armour plates, curled around legs and hung beneath the enormous pincer. Some dragged along the stone like searching roots. Others attached briefly to the surrounding ruins before peeling free and leaving behind the wet black residue Nathan had followed across the district.
The foreign biomass no longer looked like something living inside a scorpion.
The scorpion had been rebuilt around it.
Nathan crouched lower along the broken wall and watched.
The giant animal shifted.
Stone ground beneath its feet, the vibration passing through the whole structure and entering Nathan through every leg simultaneously.
It was heavy.
Far heavier than shell alone should have made it.
The abdomen contracted.
Several plates separated.
What lay beneath them moved.
Black tissue filled the spaces between organs and armour, thick living material which rose and fell with the host's motion. Tendrils emerged briefly from the exposed interior, tested the air and withdrew as the plates closed.
Nathan studied the asymmetry again.
The oversized claw.
The divided tail.
The layered armour.
The pattern could not reasonably be dismissed as random distortion.
The infection had shaped the host through use.
A successful weapon grew stronger. A useful tail became two. Armour accumulated where previous damage had demonstrated vulnerability. The scorpion's body had become a record of every problem it had survived.
Nathan's interest sharpened.
He wanted what lived underneath.
Not the carcass.
Not the shell.
The information.
He wanted to know what the black organism recognised when it rebuilt living tissue, whether the scorpion's nervous system remained an active participant or merely scaffolding, and whether anything resembling memory had survived through enough alteration to reveal where the infection originated and what other hosts existed beneath the old city.
The giant scorpion remained unaware of him.
It was feeding.
One enormous claw moved aside and exposed the remains of an animal so thoroughly dismantled Nathan could not immediately identify it. Black tendrils crawled through the carcass and returned to the host carrying thin ropes of tissue.
Nathan watched a little longer.
Then he moved.
No warning.
No territorial display.
No borrowed ritual of raised claws.
Nathan launched from the wall.
The enlarged Red-Light body crossed the gap in a rush of black-red armour and hooked legs, tail whipping behind to correct the trajectory while airborne. The infected creature reacted only when Nathan's shadow crossed its upper shell.
Too late.
Nathan struck the top of its head.
The impact shook the platform.
Ancient paving fractured beneath the infected scorpion's legs as the whole body slammed downward. The huge pincer snapped shut against empty air. Nathan's front claws caught the upper armour while his rear legs drove into the shell with enough force that several plates cracked.
Something snapped.
A piece of black armour tore free, struck the neighbouring building and shattered into smaller fragments.
The giant creature convulsed.
Both tails came forward.
Nathan released one side a fraction before the first stinger struck. It punched through armour belonging to the animal's own head and lodged briefly before black tendrils wrenched it free.
The second tail swept sideways.
It hit Nathan.
The blow hurled him across the platform.
He struck an ancient wall hard enough to collapse part of it. Blocks tumbled down around his scorpion form, stone striking stone and filling the ruined district with echoes.
Nathan tore himself out before the debris finished settling.
The infected animal was already charging.
It moved with none of the ponderous heaviness its size suggested. Black tendrils struck the ground ahead of the natural legs and contracted, hauling the scorpion forward in violent bursts. The enormous pincer swung across the platform like a battering ram.
Nathan jumped.
The claw passed beneath and tore through the damaged wall instead.
Stone exploded outward.
He landed on the creature's arm.
The giant scorpion twisted to throw him, but Nathan had already anchored several legs into cracks between armour plates. His tail wrapped around the swollen joint. One pincer entered an exposed seam.
He pulled.
The shell resisted.
Nathan increased force.
The infected creature shrieked.
No scorpion should have been able to make such a sound. It travelled partly through air and partly through stone, a deep grinding vibration which shivered through the platform and vanished into surrounding ruins.
Black tendrils erupted from beneath the armour.
Several wrapped Nathan's legs.
Another forced itself under the seam of his copied shell.
Red-Light reacted instantly.
The invading filament touched living biomass rather than ordinary host tissue.
Both organisms recoiled.
For one extraordinary moment Nathan experienced contact in neither direction cleanly enough to translate, only a violent biological recognition as two systems designed to dominate living material encountered each other directly.
The black filament tightened.
Nathan severed it.
His pincer snapped through the strand and dark tissue sprayed over both bodies.
The infected scorpion reared.
Nathan lost his grip and fell beneath the edge of its abdomen.
The creature tried to crush him.
He rolled as one leg struck the paving beside him and broke stone deeply enough for a thin line of water to appear in the crack.
Nathan lunged beneath the body.
The position denied the giant pincer room to swing.
It placed him among the tendrils.
They dropped immediately.
Black cords wrapped his shell, pulling, probing and searching for softer entry points. Nathan's copied tail struck one aside. A pincer severed another. Two more replaced it.
The fight became ugly there, too close for anything resembling a clean exchange. Nathan climbed along the underside while the infected creature slammed its own body against stone in an attempt to crush him. The platform shook repeatedly. One ancient column collapsed when the scorpion struck it sideways, broken masonry raining across both combatants. Nathan lost three legs beneath one impact, regrew two before the body stopped sliding and abandoned the third, distributing the recovered mass elsewhere.
The infected animal twisted.
Nathan felt the roll beginning.
He released.
The huge scorpion fell onto one side. Its great claw struck where Nathan had been and cracked enough of the platform that the outer edge sagged several inches before settling.
Nathan came around behind it.
The divided tails turned.
One stabbed.
He moved aside.
The second anticipated the direction and caught him through the abdomen.
The stinger drove completely through his copied body.
Nathan stopped.
The infected scorpion pulled upward.
Nathan went with it.
For a moment the Red-Light scorpion hung impaled above the platform while the giant animal lifted the tail like a spear.
Then Nathan changed.
The shell around the wound split open from inside.
Something pale emerged, A hand single humanoid hand.
Five fingers spread against the infected creature's tail.
No scorpion on earth had ever needed instincts for such a thing.
Nathan closed the fingers.
Another hand erupted beside the first.
Then another.
Two more followed.
The arms belonged to no complete body. Some ended at the elbow where they disappeared directly into red-black tissue. Others stretched unnaturally far before hands closed around armour, tail segments and exposed tendrils. The scorpion form ceased being an animal and became a structure from which Nathan grew whatever anatomy solved the immediate problem.
The first pair of hands seized the tail.
The next pulled at armour around its base.
The fifth reached deeper.
Nathan wrenched himself downward.
The stinger tore through his abdomen instead of holding him, Red-Light closed the damage while he fell.
He landed on the infected scorpion's back.
More human hands erupted around the head and shoulders.
One caught the smaller pincer.
Two forced themselves against the great claw and held it open for less than a second before the infected creature's strength overwhelmed them. Several fingers crushed into pulp.
Nathan replaced them.
More arms grew.
The shape became grotesque even by his standards: a monstrous scorpion covered in human hands, some gripping black armour while others crawled across the shell upon their fingers as if each limb were a separate animal. Red tendrils followed wherever the hands opened seams.
The infected creature thrashed, Its huge claw slammed backward.
Nathan flattened himself.
The blow missed and tore away part of its own armour, Useful.
Nathan's hands entered the break.
They pulled and the plate came loose.
Black biomass surged beneath it.
Nathan stopped treating the armour as the objective anf began to dive, Every available hand reached into the opening.
The infected scorpion understood the danger in whatever primitive way remained available to it. Its whole body twisted hard enough to nearly roll again. Tendrils flooded over Nathan, wrapping arms, crushing fingers and driving through the copied shell. One black strand penetrated deeply enough to contact Red-Light beneath.
Nathan allowed it for only for a moment.
Contact told him where the deeper mass lay, and that was exactly where he went, he grew a new arm directly toward it.
The limb punched through the broken armour.
Fingers closed around something warm, slick and muscular which had no anatomical reason to exist inside a scorpion.
The black biomass convulsed while nathan tightened his grip, and then everything changed.
Until that moment the larger animal possessed every crude advantage of greater mass. It could throw him, crush him, strike harder and absorb damage through armour accumulated over countless feedings.
Those advantages became secondary once Nathan touched the living system underneath.
Red-Light entered.
A thin filament slipped from the palm of the buried hand and penetrated the black tissue and the infection reacted with astonishing violence.
Every tendril on the scorpion's body contracted simultaneously. The giant claw slammed against the ground. Both tails struck blindly. The whole animal screamed through stone.
Nathan held on.
Another hand disappeared through the opening, Then another.
Fingers spread through black tissue while red strands followed, The infected animal tried to pull away.
Acoomplishing nothing as Nathan went deeper.
The huge scorpion staggered across the platform with him attached to its back, smashed against the ruined building and brought part of the wall down around them. Nathan lost portions of shell beneath falling stone and replaced them with more gripping limbs. Several arms extended into the masonry itself and anchored him while the scorpion attempted to retreat.
For the first time since the fight began, the larger creature could no longer decide where Nathan moved.
He had it.
Black tissue struggled beneath his grip.
Nathan could feel it trying to enter him, interpret him and consume whatever it had touched.
Red-Light answered with precisely the same intention and vastly more experience.
The infected biomass began disappearing into his hands.
Slowly, Messily, Unmistakably.
The giant scorpion shuddered. One black tendril hanging from its side stopped moving. Nathan pulled harder. An armour plate split from below as the tissue supporting it ceased belonging to the organism wearing it.
The second tail sagged.
The oversized claw struck the stone once, opened and failed to close completely.
Biological information began crossing the contact in meaningful fragments.
Cellular structures Nathan had never catalogued, Chemical signalling, adaptive pathways.
Violent scraps of an animal nervous system almost drowned beneath something more invasive.
Nathan's interest became nearly unbearable.
The scorpion bucked again, this time considerably weaker.
Nathan tightened every hand, Red tendrils spread beneath the armour in jagged veins.
The black infection fought from inside, trying to reverse the connection, but every attempt to invade him exposed another route through which Red-Light could enter.
The battle ceased being about claws, shell or tails, It became a contest Nathan understood better than almost anything alive.
Two systems of living biomass deciding which would remain itself when contact ended.
The enormous scorpion dragged itself toward the edge of the platform. Its smaller pincer scraped uselessly across stone. One tail struck again, missed and remained embedded in the floor.
Nathan climbed farther inside, Human hands disappeared to the wrists, Then the elbows.
His copied scorpion shell split wider as red tissue flowed forward, The infected creature convulsed one last time with enough force to shake loose another section of the old building.
Nathan did not move instead he had reached the core.
The moment Red-Light closed around the deepest black biomass, the larger animal's strength stopped mattering. Whatever had transformed it could still twist, infect, consume and reshape, but it could no longer escape.
Nathan had finally gotten hold of it.
The giant scorpion ceased fighting in pieces. At first the change was subtle enough to resemble exhaustion: one tendril beneath the abdomen stopped reaching for Nathan and sagged against cracked stone, its wet end twitching once before becoming still. Then the enormous left pincer, powerful enough minutes earlier to break ancient masonry like rotten timber, lost the tension holding it open and struck the platform with a hollow impact that travelled outward through the ruins. The two tails followed more slowly. One remained buried where its last strike had missed; the other curled weakly across the animal's back while Nathan's Red-Light moved beneath the armour and dismantled the host from places no external wound could reach.
Nathan did not hurry.
The battle had ended when he gained meaningful contact with the infection, but victory and understanding were different things. He had no intention of carelessly destroying the first truly unfamiliar biological system he had encountered simply because it had spent the previous minutes trying to tear him apart. The human hands protruding from his copied shell remained buried inside the host while finer red strands travelled from their palms and wrists through boundaries between black tissue, scorpion anatomy and the strange transitional structures created where one had rewritten the other. Flesh stopped being merely flesh when Nathan touched it. Every contact became information.
Red-Light processed structures with a depth no microscope, stain or mechanical instrument available at the Institute could have approached. Nathan followed proteins whose functions became apparent only after Red-Light reproduced them internally and observed their behaviour. Chemical signals moved through networks distributed throughout the scorpion's body, and the organisation gradually resolved into something far stranger than a parasite sitting inside a host.
The infection existed everywhere.
It had threaded itself through nerves, muscle, connective tissue and organs, learning the architecture already present and revising it whenever survival rewarded a particular answer. The original animal had become less a victim carrying an intruder than a foundation upon which another biological system built continuously.
The giant pincer had not simply overgrown.
Repeated success had encouraged reinforcement.
The armour was not random mutation.
Damage had taught the infection where armour was needed.
The divided tail represented the same principle pushed farther, duplication arising not through generations of inheritance but through pressure applied repeatedly within one living body until the thing controlling adaptation produced another answer.
Nathan absorbed slowly enough to preserve those relationships.
Red filaments slid beneath overlapping plates and separated them from the black tissue binding them together. One section of abdominal armour lifted with a cracking sound like wet timber splitting, exposing dense layers below which writhed the moment cave air reached them. Nathan entered before they could withdraw. The black flesh darkened under contact, lost cohesion and came apart into long ropes drawn toward him through dozens of red tendrils.
The infected scorpion convulsed.
Its smaller claw scraped once across the platform.
Nathan tightened around it.
The appendage came away not through one violent tear but by being dismantled from inside. Red-Light entered the joint, stripped away everything providing structure and followed the black tissue as it retreated up the limb. Muscle, armour, altered nerve and infection were processed together until the claw collapsed into fragments, and those too disappeared moments later.
The creature tried one final time to rise.
Its surviving legs pressed against the old paving and raised the enormous abdomen several inches. The platform groaned beneath the shifting weight. One broken tail tore free of the stone in a spray of chips. Black tendrils around the abdomen revived simultaneously, some striking at Nathan while others attached to walls and pillars in an attempt to drag the host away.
Nathan's own scorpion shell opened along the underside.
A forest of red tendrils spread across the platform.
They wrapped pillars, entered cracks and anchored around stone. Others crossed into the infected animal from every direction. What had begun as one creature clinging to another became difficult to separate visually; black cords twisted around red while red strands disappeared into black, and ancient paving vanished beneath living tissue pulling in opposite directions.
Then Red-Light began winning everywhere at once.
The raised body dropped.
The infection tried to reproduce itself into Nathan as fast as he consumed it, employing the same invasive strategy that had worked upon lesser hosts. Black tissue entered one exposed red tendril and immediately began releasing signals designed to interrupt ordinary cellular boundaries and repurpose the invaded material.
Nathan allowed it several millimetres.
Then Red-Light enclosed the intrusion.
The foreign organism found no passive host cell waiting to be hijacked. It encountered living tissue which recognised the chemistry, copied it, isolated it, learned its mechanism and began consuming the machinery intended to consume.
For one brief biological moment Nathan experienced something almost like hesitation from the infection.
There was no evidence of thought. No mind speaking through chemical signal. Yet behaviour altered. The black tissue stopped advancing and attempted to withdraw.
Nathan refused to let it.
He followed the retreat directly back into the host.
The great scorpion began disappearing.
One rear leg collapsed first. Armour cracked as everything beneath it was drawn inward through red filaments, leaving the shell unsupported until that too disappeared. Another leg followed. The enormous pincer lasted longer because so much mass had been invested there, but once Nathan penetrated the root of the joint the limb became another reservoir to process.
Thick black tissue flowed beneath the shell and entered Nathan in ropes, carrying with it memory which was not memory in any human sense.
Hunger, Pressure, Heat.
Prey, Injury, Adaptation.
The pattern repeated like a law written through the organism.
Encounter, Survive, Change, Encounter again.
Nathan absorbed deeper.
The scorpion's original nervous system remained within the infection, though distorted almost beyond recognition by years—or perhaps generations—of alteration. Fragmentary impressions emerged. Crawling through stone while much smaller. Hunting insects. Warm soil carrying an unfamiliar scent. Pain as black filaments first forced themselves between abdominal plates. A period of frantic movement Nathan interpreted only as sickness.
Then survival.
Afterward everything simplified.
Eat, Grow, Return.
Nathan stopped within the borrowed fragments.
Return.
He drew more of the creature into himself.
The scorpion thrashed weakly beneath him, but the physical fight no longer held Nathan's attention. He searched the sensory impressions the way he might have worked through the broken memories of a damaged human mind, ignoring repetition and following associations tied to place.
Stone, Water, Roots, A mineral taste.
Heat rising through cracks.
The scent of flowers.
Nathan's attention sharpened.
The scorpion possessed no human concept of flowers. The information existed only as chemistry: pollen carried through warm air and soil, a biological signature connected so strongly with the infection that even the altered arthropod's primitive nervous system had retained the route toward it.
There.
Nathan took the rest.
The enormous head came apart beneath him. Humanlike hands forced the remaining plates open while tendrils plunged into the exposed cavity, and whatever fragment of the original animal still existed disappeared into Red-Light along with the black tissue surrounding it. Both tails collapsed. The oversized claw dragged once across the platform from reflex rather than intention and was pulled inward afterward.
The process accelerated once resistance ceased.
Armour broke and vanished beneath red growth. Tendrils which had made the creature so grotesque were seized at their roots and dragged from within, some stretching several feet before internal attachments tore loose with wet snapping sounds. Nathan consumed them before they touched the ground. Abdominal segments opened like overlapping doors as Red-Light forced itself underneath and removed the black mass packed behind them in pulsing sections.
Within minutes almost nothing remained.
A smear of black fluid lay beside one stone.
A tendril passed over it.
Gone.
One fragment of armour remained near the edge.
Nathan touched it.
That disappeared too.
Silence settled gradually across the ruined platform.
The fight had damaged almost everything around it. Part of the old building had collapsed inward. One pillar lay broken over the paving. Cracks crossed the platform and allowed narrow lines of water to shine between blocks. Fine pieces of mineral crust continued drifting down long after both bodies stopped moving.
At the centre of the destruction stood a scorpion.
Nathan's scorpion.
Only it was no longer remotely the size of the creature he had begun with.
The assimilated mass had swollen him enormously. His copied shell expanded as Red-Light redistributed itself, retaining the general scorpion plan because the shape remained effective while discarding almost every limitation of genuine arthropod biology. Legs thickened until each carried weight natural anatomy could never have supported. Pincers became broad enough to fracture old masonry. The tail rose behind in a heavy reinforced curve.
Nathan remained still for several seconds while the new biological information organised itself.
The infection moved inside him only as something contained and studied. It no longer existed independently as it had inside the larger scorpion, but its instructions remained intact enough for examination.
He turned his attention inward.
The resemblance to Red-Light existed.
So did the difference.
The black organism could consume biological material, alter a host rapidly and use experience to shape later structure, but it did not appear capable of taking another organism's identity the way Nathan could. There was no complete assimilation of biological history, no reconstruction of an eaten animal's memories and no evidence that the scorpion had become anything it fed upon. The mechanism was cruder and, in another sense, more natural.
It treated living things as material and examples.
Feed.
Survive.
Alter toward whatever continued working.
Natural selection compressed into the lifespan of one organism.
Nathan found that more disturbing than intelligence would have been. Intelligence could choose badly. It could misunderstand, hesitate, become attached to the wrong solution.
This thing only needed to survive.
The foreign structures remained separated behind layers of Red-Light while Nathan reproduced individual mechanisms and destroyed each experimental copy after observation. He tested the signalling associated with armour growth. The response which redirected tissue after injury. The pathways allowing host structures to change while remaining functional.
The relationship with plant compounds held him longest.
The signatures he had detected earlier in the river were present everywhere inside the infection.
Not contamination.
Connection.
Trace compounds were embedded throughout the altered biology deeply enough that Nathan could follow them backward through the scorpion's primitive sensory history.
They did not point toward the river.
They pointed upward.
Deeper into the forbidden country and yet higher through the mountain.
Toward somewhere the infected animal had returned to repeatedly.
Nathan searched again.
The scorpion had travelled there through darkness, following warmth across old routes. Architecture eventually became natural passage. The incline increased. At one point the creature crossed ground so heavily travelled by other infected animals that chemical traces overlapped into a confusion of threat and familiarity.
Then came stairs.
Not little steps hacked into a mine.
Great stone stairs.
Nathan received them only through arthropod perception: enormous vertical faces encountered one after another, climbed through cracks and damaged corners because the original creature had been too small to treat them as stairs at all. The route rose continuously. Warm air moved down. Pollen settled into sheltered stone.
And something lived above.
Not one thing.
Many.
Nathan followed the remaining fragments.
Brightness.
That surprised him.
The scorpion remembered light.
Perhaps a vast cavern, perhaps an opening to the surface, but something large enough for daylight to reach. Heat against black armour. Vegetation thick enough for an arthropod to disappear beneath it.
Flowers.
Their chemical signature matched the traces Nathan had already found in the river and infection.
The memory dissolved there into hunger and repeated feeding.
Nathan knew enough.
The name surfaced from Kafele's memories before he deliberately searched for it, an old phrase connected to taboo, pilgrimage, childhood warning and stories which had passed through so many generations that no one claimed to know where they began.
The Stairway to the sun.
Nathan stood amid the broken ruins for a while and allowed the phrase to settle.
Kafele had never climbed it.
Few living Ndipaya had.
In the memories Nathan had stolen, the route existed as one of those places made more powerful through absence. Children knew the name long before they understood where it was. Hunters knew which lower roads eventually approached it and knew just as certainly not to follow them. Elders changed the stories depending upon who was listening. Some versions said the gods descended by those stairs. Others said the first Ndipaya climbed from deep earth toward the sky. Another claimed the place above was where life had first been made strong if they were strong enough to survive the process.
The Ndipaya believed this place was where men strong enough became gods ... now the
myth had just become much more interesting.
Nathan moved.
The enlarged scorpion crossed the damaged platform and descended through the ruins rather than returning the way he came. Its new scale altered every obstacle. Stones which had been walls to the original animal became footholds. Gaps which would once have required long detours disappeared beneath a single stride. When he reached the lower avenue his claws struck old paving hard enough to fracture the mineral crust collected over centuries.
He followed remembered chemistry rather than a conventional route.
There was little uncertainty now. The infected scorpion had given him its familiarity directly. Nathan recognised which air currents belonged to the deeper territory, which mineral traces accompanied the correct passages and which stones carried the residue of altered animals moving repeatedly across them.
The ruined city climbed.
Nathan scurried through a collapsed court and up the remains of a monumental staircase whose centre had fallen away generations earlier. Where the route broke, he crossed the wall. Where a block sealed an opening, his great pincers found purchase and dragged enough stone aside for the body to pass.
Black residue increased with elevation.
It no longer belonged to one animal.
A dark smear beneath an arch contained altered insect tissue.
Nathan sampled it.
Infected.
A dead centipede lay beside another stair, thin black fibres dried between its segments. Higher still, something that had once been a small rodent rested against a wall with its skull split from inside and hardened growth surrounding the spine.
Nathan examined each briefly.
Different species.
Same underlying process.
The infection was not restricted to scorpions.
One question closed.
Dozens opened.
The Stairway to the sun waited somewhere above.
Nathan began feeling warmer air descend.
At first the change was slight, little more than a few degrees registered across the sensory structures of his enlarged form, but the difference strengthened as he climbed. Mineral cold gradually gave way to moisture and organic chemistry.
Vegetation.
Living vegetation.
Far beneath the mountain.
The stone road narrowed between two enormous walls and turned sharply upward.
Nathan stopped.
The first stair rose before him.
Even at his enlarged scale the step reached almost to the height of his body.
Behind it stood another.
Then another.
Another beyond that.
The staircase vanished into darkness above, broad enough that dozens of men might once have climbed it abreast. Countless feet had worn shallow depressions through the centres of the steps, while portions near the edges remained sharp enough to preserve old tool marks. Pillars flanked the ascent, some broken and others continuing upward until they disappeared into blackness.
Warm air flowed down between them.
Pollen came with it.
Nathan's scorpion body reacted before he consciously interpreted the chemistry.
The isolated infection inside Red-Light recognised it.
Not as thought.
Not as control.
Something simpler and older than either from the scorpions instincts.
Source.
Nathan remained at the foot of the Stairway to the sun for several seconds while the vast ascent disappeared above him. Far beyond miles of stone, water and marsh, his human body slept beneath canvas in the Ndipaya settlement while British soldiers and hunters watched the trees for a red creature they could not find. Down here, in country no villager had willingly entered for close to a century, Nathan carried within himself the first intact biological answer he had obtained since coming to West Africa, and that answer recognised whatever lay above.
He lifted one great pincer onto the first worn stone step and pulled the enlarged body upward, rear legs finding purchase while the heavy tail shifted behind him to balance the climb. The first stair disappeared beneath him. Another rose ahead, its surface worn by feet belonging to people dead so long their names had passed out of memory, and beyond that another waited in the darkness.
Nathan began to climb.
