Deep within the dark-green warp rift, the Pale Rose was navigating its exit from the distorted coordinates of space. This former Imperial Heavy Cruiser had long since lost its original structural profile. The exterior hull was entirely encrusted under a dense layer of rust and dark-yellow pustulant moss. Thick, pink vascular networks wrapped around the primary macro-cannons and the bridge infrastructure like parasitic vines, pulsating rhythmically to pump contaminated bodily fluids to every independent corner of the warship.
The viewing ports of the bridge had long been substituted with translucent membranes of mutated flesh; tracking through the film, the interior simulated the continuous contraction of a massive, beating heart.
Rust Phelps stood firmly at the center of the bridge—or rather, his biological form had long integrated completely into the flesh architecture of the vessel. The life-support conduits sprouting from his power armor had fused seamlessly into the fleshy dais of the command deck. Dark-green pus continuously oozed out from the seams of his armor plates, only to be reabsorbed by the underlying tissue and recycled back through the life-support loop.
His upper torso maintained a vaguely humanoid silhouette, though his heavy plague power armor was severely pitted with rust, corrosion, and open cavities bulging with decaying meat. His face was completely decomposed; a milky, ruptured eyeball hung loosely outside its socket, sustained strictly by a few stray structural fibers. Yet matching the baseline profile of most Plague Engineers, a specialized face mask and hood effectively concealed his grotesque appearance.
"Heh... hehehe..."
Phelps discharged a labored, raspy laugh, the contaminated fluids anchoring his thoracic cavity bubbling in synchronization with his amusement. He analyzed the live telemetry streamed back from the tracking arrays. Noting that the Imperial fleet had declined to advance and purge the decoys, electing instead to disperse their formation, maximize distance parameters, and pour their long-range salvo directly onto the rift exit, a trace of appreciation flashed through his milky eye.
"Intriguing. It appears someone has correctly deciphered my minor jest."
A Death Guard marine stood hunched over adjacent to his position. The Mark III "Iron" pattern power armor worn by this Astartes of Nurgle was so profoundly corrupted that its baseline production designation was entirely unrecognizable.
"Sergeant, the Imperial whelps have dispersed. Our decoys have been rendered tactically ineffective. Shall we command the vanguard hulls to execute maximum acceleration and close the distance?"
"What is the urgency?" Phelps articulated slowly, a faint green mist drifting from his lips with every syllable he formed. "Deciphering the decoy arrays explicitly indicates they harbor veterans who have personally witnessed the Grandfather's glory."
"Splendid. This ensures the engagement will retain an index of entertainment."
He indubitably recognized that the decoy protocol was not guaranteed to deceive every independent commander. Yet it had never been engineered as a definitive victory variable; it was merely an operational appetizer. Even if the adversary bypassed the trap, forcing them to scatter their firing lines and abandon the high-density defensive grid of the starport achieved his primary tactical goal.
The Imperial Tithe Fleet was fundamentally an array of logistical transport hulls refitted for combat; they suffered from low mobility parameters and operated at peak efficiency when anchoring defensive engagements adjacent to starport bastions. Once forced out into open space to engage across dispersed coordinates, their defensive cohesion would degrade significantly.
Phelps genuinely preferred to withhold the execution timeline. According to his original operational framework, he should have delayed for another half a solar cycle, waiting until the pathogens within the Underhive fully incubated, and the interior of the Hive City collapsed entirely into absolute anarchy. He intended to wait until the Imperial forces and those xenos dregs tore each other apart in a war of attrition before deploying his fleet to harvest the system.
Yet the revelation of the Grandfather had descended three solar cycles prior. The divine message indicated that if he delayed further, the fruit would be harvested entirely by the whelps of the Changer of Ways.
That Tzeentchian sorceress playing her shadow games beneath the fortress infrastructure was moving with significantly greater velocity than his analytical metrics had projected. If he delayed any longer until she secured absolute dominion over the surface topography, securing Brevis would demand an immense expenditure of operational resources.
Consequently, he arrived. Even if the chronological window fell short of absolute perfection, and even if it demanded a direct fleet engagement against an Imperial Tithe Fleet, he was bound to strike.
"Brevis is the garden of the Grandfather," Phelps articulated with fanatical piety, the edge of his power axe lightly tapping against the fleshy deck plates, discharging a dull thud. "Whether it concern the lapdogs of the False Emperor, the deceivers bound to the Changer of Ways, or those xenos organisms lurking within the shadows..."
"Ultimately, all shall bathe within the grace of the Grandfather and fuse into absolute unity."
"Transmit the directive: all warships are to maintain a disciplined advance. Initialize primary weapon configurations; execute a synchronized salvo the exact millisecond we close to optimal operational range."
"Target: the Gemstone."
His singular functional eye locked tightly onto the most prominent Imperial flagship displayed across the tracking matrix. A raspy, mocking chuckle resonated from beneath his breathing mask. Provided they could execute a successful boarding action to seize the Gemstone and inject the pathogen strain, the entirety of the Tithe Fleet would transition into a new plague armada. When that transpired, the whole of Brevis and the entire Calixis Sector would transform into a playground for Nurgle. That would comprise the ultimate tribute presented to the Grandfather.
Three levels beneath Castle St. Garus, interior to the Nine-Sided Spirit-Sealing Boundary.
A deep blue sorcerous light vibrated continuously as nine Chaos Knights maintained a circular formation, anchoring Guyu and the remaining survivor veterans at the absolute center of the perimeter. The bombardment from the Volcano Cannons and Melta Cannons sustained an uninterrupted cadence, slamming flush against the psionic lattice to discharge bursts of light across the chamber, yet they continuously failed to rupture that seemingly delicate line of defense.
Luna hovered along the elevated platform marking the absolute edge of the boundary, the gold half-mask covering her face projecting a cold reflection. The sorcerous staff gripped in her hand tapped lightly against the platform, continuously adjusting the energy distribution vectors of the warding arrays while dictating the offensive tempo of the nine Knights.
She experienced zero urgency. The local chronological velocity had been throttled to a tenth of its standard metric; she possessed an immense index of patience to systematically erode Guyu's psionic reserve, tearing apart this Chosen construct of the Tyranid hive strain piece by piece.
Once Guyu was entirely depleted, she would leverage the boundary to ensnare the reinforcements deployed by Raynor, ensuring the friction separating Dominic and Raynor across the surface topography erupted into total warfare. When that node stabilized, she would strike directly from the rear to secure absolute dominance, claiming the entirety of Brevis under her hand.
Yet at that exact millisecond, her cognitive center experienced a sudden, violent jolt.
The multifaceted crystal crowning her staff began to flash frantically without any pre-existing warning indicator, the deep blue light fluctuating erratically as the energy currents stabilizing the boundary registered a momentary desynchronization. Luna snapped her head upward, the pupil concealed beneath her mask contracting instantly.
A warp rift... the Eastern Anchorage Zone... a Nurgle fleet?!
"Frak it!"
She spat a low curse, her historically unshakeable register harboring an open index of unadulterated rage for the first time. The plague fleet—those repulsive maggots!
Her operational blueprint had successfully advanced to its most critical execution node. Dominic had already generated deep suspicion toward Raynor; provided she secured merely a few more solar cycles, she could force the two actors into a absolute schism, converting their tension into an open military engagement.
Yet those lunatics of Nurgle had chosen this exact chronological node to materialize, driving their fleet straight onto the doorstep of the starport!
Luna tightened her grip around the staff, her knuckles whitening with anger. She indubitably recognized the true origin matrix governing the Underhive plague. That particular Death Guard warband had been lurking along the periphery of the star system across an extended timeline; she had even secretly manipulated the data streams to obscure their warp signature from standard scanners, explicitly to ensure the pathogen would generate greater chaos within the Underhive and introduce complications for Raynor.
Yet she completely failed to project that these lunatics would possess the audacity to directly initiate a head-on fleet engagement against the Tithe Fleet! This completely disrupted her strategic calculus to guide Raynor and Dominic into mutual annihilation. Interruption—pure, unadulterated interruption!
Luna's chest heaved a few times as she forcefully suppressed the fury anchoring her mind, compelling her cognitive modules to return to absolute rationality.
Negative.
Analyzing the variables from an independent perspective, this failed to map definitively to a negative outcome.
With the Nurgle fleet initializing an engagement, Dominic would find himself entirely consumed, his total analytical focus dragged exclusively onto the void theater. With his own assets gridlocked in a fight for survival, where would he secure the operational capacity to police the surface cults or demand accountability from Carey Von? He might even be forced into a position of operational dependency, relying on Raynor's ground forces to establish a joint defensive perimeter against the Chaos invasion.
Processing the data through this lens, the historical checkmate matrix effectively transitioned back into a fluid, viable sequence. With Dominic paralyzed by the void engagement, he would possess zero capacity to intervene across surface operations within the short term. This afforded her a significantly expanded window to methodically drain Guyu's lifeforce before pivoting to liquidate Raynor.
As for those dregs of Nurgle... Once she finalized the internal purge, she possessed all manners of protocols to systematically dismantle them at her leisure.
The grand strategy governing the Changer of Ways was historically immune to being unseated by one or two anomalous chess pieces. Luna curled her lips, the expression beneath her mask reclaiming its characteristic composure. She elevated her staff once more, as the deep blue sorcerous light stabilized back into a balanced cadence.
"Everything... remains entirely within parameters."
Inside the corridors of the second subterranean level, Raynor semi-crouched behind a temporarily erected alloy barricade, continuously monitoring the incoming telemetry reports. The casualty metrics of the vanguard forces sustained a continuous upward trend; the sorcerous traps Luna had seeded across the second stratum scaled as significantly more devious than those on the first layer. Space folding, psychic murmurs, and daemon-summoning nodes lay concealed within every independent conduit and blind corner.
Right at that chronological node, the exceptionally faint rustle of fabric friction resonated from behind.
A Purge Bishop dropped soundlessly adjacent to his flank. The violet pupils shadowed beneath his hood harbored a trace of severe gravity as he projected the intelligence directly into Raynor's cognitive center via the symbiote's psychic link:
"My Lord, a sudden anomalous disruption has materialized across the orbital void."
"A warp rift has expanded directly outside the Eastern Anchorage, and a Nurgle fleet is currently forcing its ingress into realspace."
"The Tithe Fleet has initialized Tier 1 combat readiness, and open engagements have already erupted."
Simultaneously, a highly unstable and blurred visual feed of the starry void flooded Raynor's consciousness. It generated a baseline depiction of the space surrounding the Brevis starport, initializing with the corrupted task force. The foul, stench-ridden armada forced its hull structures out from the warp tear while Dominic systematically dispersed his battle lines.
Nurgle.
They indubitably arrived at a calculated operational node.
Raynor's brow twitched subtly, zero panic anchoring his mind; instead, a trace of absolute realization flashed through his analytical faculties.
The pathogen epidemic dominating the Underhive had materialized under highly suspicious variables, its propagation rate and mutation vectors scaling far beyond ordinary Hive City plagues; he had long harbored deep suspicions that the shadow of the Death Guard was anchoring the background.
It was strictly because the adversary remained buried too deep to leave definitive footprints, failing to project that they would possess the audacity to leap directly into the open at this exact crisis node.
"Can you verify the designation of the warband?" he inquired across the mental loop.
"The adversary's plague signatures register as highly specialized, possessing the capacity to directly infect mechanical infrastructure."
"Localized sections of inorganic matter within the Underhive have manifested severe corrosion and flesh growths despite zero manual contact with infected personnel," the Bishop supplemented. "The accompanying Tech-Priests of the Adeptus Mechanicus have rendered a preliminary diagnostic, mapping it as a variant of 'warp corruption.'"
A warp pathogen capable of corrupting and infecting mechanical systems...
The Ferric Blight. These explicit words materialized abruptly inside Raynor's mind. He retained a clear indexing of this notoriously infamous warp plague within his memory banks.
Under the operational umbrella of the Death Guard resided a specialized warband designated the "Pale Hand." These traitors wielded a unique pathogen strain explicitly categorized as the Ferric Blight. It possessed the capability to corrupt the vast majority of mechanical fabrications, scaling down to standard lasguns and scaling up to capital ship engine cores and Knight chassis.
Provided a component sustained contact, the metal would oxidize into severe rust within a mere sequence of hours while sprouting deformed biological tissue, ultimately rendering the machine a total plaything of Chaos.
Across a later timeline in M42, an independent Knight World anchoring the Segmentum Obscurus fell entirely to their machinations. The Pale Hand warband leveraged a feigned retreat to manipulate the Knights into executing a deep pursuit, ultimately contaminating them with the Ferric Blight. Under the continuous erosion of the viral strain, they systematically corrupted half the chassis anchoring the entire Knight House. This catalyzed the genesis of a renegade Knight warband designated the "Rust Hounds," who initialized hunting operations targeting the souls of their former battle-brothers.
"The adversary's objective scales as highly transparent now," Raynor stated, rising to his feet while brushing the loose dust from his knees. "Within a backwater frontier planet like Brevis, there exist strictly two assets of sufficient value to command this volume of operational expenditure from the Death Guard."
The initial asset comprised the Knight chassis belonging to House St. Garus. Operating as the final surviving Knight House within the Calixis Sector, even if they presently sustained nothing superior to an empty administrative shell, those ancient chassis and machine spirits handed down across ten millennia functioned as prime raw materials for the Pale Hand, who excelled at corrupting machines.
The secondary asset comprised the STC blueprints entombed deep within the subterranean foundations of Brevis. The thirst the forces of Chaos harbored toward STC technology scaled as zero percent weaker than that of the Adeptus Mechanicus.
Luna's machinations beneath the earth focused heavily on borrowing an independent blade to execute an assassination, plotting a total usurpation of regional power. Conversely, these lunatics of the Pale Hand locked their sights onto the Knight House and the STC, scheming to convert the entirety of the planet into their baseline testing ground.
Raynor discharged a cold scoff.
Intriguing.
Processing standard tactical logic, the Pale Hand possessed the total capacity to delay their execution timeline. They could have waited until he and Dominic completely severed their operational ties over the Genestealer variable, or until Luna successfully muddied the political waters of the planet further. Striking when the human factions had exhausted their assets to their most vulnerable tier would have effectively doubled their probability of victory.
Yet they explicitly elected to leap into the theater at this exact chronological node. Did they detect the subtle movements of the Changer of Ways, fearing that Luna would harvest the fruit ahead of their timeline? Or did an independent, hidden variable compel them to advance their deployment window?
Ultimately, the baseline root cause had ceased to matter. The critical variable was that this suddenly arriving Nurgle fleet had inadvertently broken the tactical gridlock, resolving his immediate political complications. Even if Dominic harbored an intense desire to demand accountability regarding the Genestealers, when confronted by an open Chaos invasion, his command modules would accurately prioritize strategic gravity.
Internal Imperial accounts could be audited across a later timeline; but when Chaos initiated a breach at the doorstep, the fleet was bound to present a unified external front. This mapped to an absolute protocol engraved directly into the bone structure of every Imperial warrior.
"Notify the Governor's Palace," Raynor articulated, his register sharp and decisive. "Deploy the entirety of the Expeditionary Fleet immediately to reinforce the Tithe Fleet."
"Mobilize the Second and Fourth Vanguard Defensive Divisions, ordering them to establish immediate defensive perimeters surrounding the starport infrastructure."
"Initialize all anti-orbital defense batteries to absolute maximum output, and activate every ground-based defensive fortification."
"Furthermore, detach an independent heavy assault regiment, commanding them to maintain full readiness to initialize boarding support operations."
"Inform Fleet Command that the Vanguard forces are completely subordinated to the operational routing of the Tithe Fleet; they possess zero requirement to report back to my station for authorization."
He harbored zero intent to dispatch a specialized transmission to Dominic to render an explanation. Articulating excessive data at this stage would merely simulate a calculated attempt to curry favor, projecting a false index of internal weakness. The physical movements of the Vanguard forces functioned as his definitive statement. Internal friction remained distinct as internal friction; but with Chaos current, he would decline to stand idly by. This comprised the ultimate response.
"Understood." The Bishop bowed to accept the directive, his silhouette blurring before vanishing completely into the surrounding shadows.
Raynor refocused his gaze onto the tactical terminal, tracking the boundary markers mapping the third subterranean level. The external strategic pressure had stabilized temporarily, yet the engagement within this theater demanded a absolute conclusion. Luna intended to leverage the arrival of Nurgle to buy time; he would explicitly deny her that luxury.
"Transmit the directive: the breakthrough elements are to accelerate their advance velocity," his voice dropped to a cold register. "Within thirty minutes, I intend to stand directly before the ingress point of the third stratum."
Above the orbital plane of Brevis, the flames of open warfare had ignited the expanse of space.
The thunderous discharges of macro-cannon salvos traversed the physical hulls and the vacuum of space, still transmitting deep into the command decks, sounding as low and heavy as distant planetary lightning.
Inside the bridge of the Gemstone, every independent officer maintained a highly taut expression, their tracking sensors locked firmly onto the live telemetry data cascading across the primary monitors.
Dominic stood with his hands locked behind his back before the viewing port, his military dress uniform perfectly pressed, the general's insignia gracing his left shoulder flashing intermittently under the reflective light of the distant plasma discharges. He monitored the spheres of fire erupting across the downrange coordinates, his pupils deep and analytical.
The Imperial fleet had successfully executed its fan-shaped dispersal, sustaining a strict minimum separation baseline of five hundred kilometers; the fire network established by the synchronized lances and macro-cannons poured an uninterrupted stream of ordnance toward the coordinates of the warp rift.
Macro-cannon shells trailing white exhaust streaks slashed through the void, slamming flush against those bloated, putrid Nurgle warships to discharge cascades of oxidized shrapnel and dark-green biological sludge.
Yet the projected high-velocity annihilation failed to materialize.
These voidships—completely stripped of void shields or any variant of energy-based shielding, whose primary hull armor had been substituted entirely by corrupted meat and oxidized metal—demonstrated a structural durability that triggered severe psychological friction across the analytical modules of the crew.
A single macro-cannon shell possessed the kinetic output to comfortably breach the armored belt of a standard escort frigate; yet when impacting a plague frigate, it achieved nothing superior to blasting an open, blood-soaked crater across the tissue. Beneath the spraying pus and fragmented flesh, ruptured vascular networks would instantly writhe together in synchronization.
New cellular buds expanded at a velocity visible to the naked eye to fill the structural wound; within less than twenty seconds, the blown-out cavity would be entirely plugged by hyper-proliferating meat, leaving nothing superior to an uneven, putrid scar of corrupted flesh.
The cruisers operating deeper within the formation displayed even more exaggerated metrics.
The high-energy beams projected by the lance arrays sliced through the hulls, incinerating massive sections of the flesh-based structure to expose the heavily oxidized metal skeletons anchoring the interior.
Yet those structural frames were rapidly overrun by viscous tissue networks, propagating like fungal spores to completely wrap the damaged hull components once more. They even sprouted new, pustule-shaped weapon barrels, projecting thick streams of corrupted fluid ordnance back toward the Imperial line.
They simulated a column of mangled meat that sustained total locomotion despite being systematically crushed, displaying the absolute resilience characteristic of the Grandfather's chosen assets.
Beyond the Pale Rose navigating the absolute rear of the array—which managed to retain a relatively intact structural configuration—the remaining dozen-plus warships had transitioned into highly fractured states under the saturated fire network, the pustulant moss encrusting their hulls peeling away in massive sheets. The vascular networks had sustained countless ruptures, causing the vessels to surface from a distance like a column of thoroughly mangled, floating corpses.
Yet not a single hull terminated its advance vector.
Braving the sky-blocking fire network, they sustained their advance toward the Imperial fleet elements with a sluggish yet completely unyielding velocity.
