The psychic tempest rolled through the center of the array, purple shockwaves crashing against the surrounding ghostly blue barriers like rising tidal waves.
Sarah tightened her grip on the hilt of the spinal greatsword. The segmented blade vibrated slightly, emitting a low, resonant drone like an apex xenos beast finally awakening from a millennia-long slumber. With every structural pulse, raw, catastrophic power cascaded up her arms and flooded directly into her veins.
This was no ordinary psychic weapon.
From the precise millisecond they had crossed the threshold into this stagnant domain, the three Maguses accompanying the deployment had never been intended as simple auxiliary support units. They were vessels; they were the blade itself—a decisive counter-strategy engineered by Rena specifically to execute Luna.
The Spirit-Sealing Array could suppress collective psychic networks and sever the remote transmission of the Hive Mind's consensus. It could detect high-intensity energy profiles, yet it remained entirely incapable of piercing the advanced biological camouflage at which the Tyranid race excelled.
Rena had systematically disassembled and restructured a massive spinal greatsword carrying thirty percent of her primary body's total output, dividing the core framework, psychic reservoirs, and amplification nodes into three distinct biological payloads. She then embedded them within the three Maguses, distributing the components across three separate skeletal systems.
Isolated, they manifested merely as three fourth-generation hybrid Maguses with slightly elevated psychic profiles, their bio-signatures indistinguishable from standard high-tier acolytes. Even the Tzeentchian sorcerers were entirely incapable of detecting the anomaly.
Yet the millisecond their biomass fused and the three bodies unified, the genetic restrictions buried deep within their bone marrow completely unlocked. The entire biological mass and psychic reserves of the three Maguses compressed and distilled within a single microsecond, ultimately consolidating into this four-and-a-half-meter spinal greatsword.
It was not an external tool; it was the biological continuation of three high-tier hybrids—a blade delivered directly into Sarah's hands across the boundaries of the array!
Standing with the weapon in hand, Sarah's psychic level climbed at a terrifying velocity. Pale purple luminescence overflowed from her frame, turning into near-material currents of incandescent fire. That profile had long transcended the definition of a mere "Chosen creation," carrying an ancient, vast oppression characteristic of a primary Hive Mind core. For a brief window, her signature forced its way up to match the exact energy profile of the Frost Dragon itself.
The current Rena was no longer the fragile Tyranid Warrior that had first arrived in the underhives of Necromunda. Sustained by the rich biomass of dead worlds, augmented by the system attributes of the Tyrant's Crown, and driven through countless evolutionary adaptations catalyzed by endless warfare, she had long completed her transition from a singular organism to a composite Hive Mind nexus.
The Frost Dragon's primary body currently possessed both the formidable frame and biological productivity of a Flying Hive Tyrant, the psychic control and cognitive dominance of a Maleceptor Tyrant, and the refined psychic precision granted by the system—far eclipsing the conventional limits of the Tyranid race. Even a single slash from a proxy entity, backed by this peer-level energy injection, was more than enough to crush every living asset within this array.
"ROAR!"
The two Chaos Knights that had been violently thrown back by the initial psychic wave stabilized their multi-ton chassis, unhuman roars erupting from their chest cavities. The Chaos runes etched across their armor plating flared frantically, and their corrupted machine spirits collapsed into unmitigated madness under the pouring influx of warp energy.
The knight on the left flank rolled its wrist, reversing the trajectory of its Reaper Chainsword as the teeth whined with an ear-splitting shriek, sweeping horizontally toward Sarah. The unit on the right dropped its knees and dipped its shoulder, arcs of electricity crackling violently across its Thunder Strike Gauntlet as it brought the massive fist down with catastrophic force, targeting her skull.
Left and right, they completely boxed out her avenues of evasion.
The pilots of both war machines were fallen scions of the Sanctus Gallus line who had bartered with Chaos to secure physical capabilities far beyond the human threshold. Furthermore, the combined firepower and close-quarters capability of a singular knight chassis was naturally sufficient to obliterate an entire Imperial tank company in a frontal engagement. In Luna's original strategic calculus, these nine knights comprised the absolute foundation of her bid to conquer Castle Sanctus Gallus.
Yet the very next millisecond, the visual telemetry within their targeting viewports experienced a sudden glitch.
Like an ancient pict-projector dropping critical frames, Sarah stood near the altar a dozen meters away one instant; the next, her silhouette simply slid forward several meters without warning. It was not instantaneous teleportation; rather, the local temporal flow surrounding her frame had been forcibly warped.
Leveraging the massive psychic payload liberated by the spinal greatsword, Sarah had temporarily disrupted the localized temporal rules governing the array. The overarching hundredfold deceleration of the domain remained active across the theater, but within a one-meter perimeter encompassing her body, the temporal flow had been forcibly accelerated to match the baseline speed of the external universe.
Under this stark, localized contrast of velocity, her physical actions reduced to fragmented, disjointed frame-movements in the eyes of observers.
Sarah stepped through the air, the atmosphere beneath her boots consolidating into solid platforms. Her first step landed squarely onto the flat spine of the encroaching chainsword, her footfall so deceptively light that it forced the heavy, whirling blade downward by a fraction. Her second step pressed against the face of the oncoming power fist; the crackling electrical arcs froze for half a second the exact microsecond they made contact with the sole of her boot, looking as though they had been suspended in ice.
Her grey robes snapped violently amid the hyper-velocity movement. Her four arms securely locked around the hilt of the spinal greatsword, bringing the weapon level with the blade oriented forward. There were no redundant maneuvers, no elaborate psychic spells—merely a singular, horizontal slash executed with absolute simplicity and purity.
Yet contained within this single strike was a concentration of psychic energy matching Rena's primary body, the entire baseline payload purchased through the life-sacrifices of three high-tier Maguses, and the terrifying acceleration generated by the distortion of time.
SPLAT!
The sound was exceptionally faint, resembling a razor-sharp scalpel slicing through fine vellum.
A near-transparent spatial fissure rippled outward along the trajectory of the bone blade. Wherever the edge passed, the air was cut completely open, leaving behind persistent dark streaks that refused to dissipate.
The movements of the two Chaos Knights instantly locked into static frames. They remained suspended in their offensive postures—the teeth of the chainsword still rotating at maximum RPM, the arcs of the power fist still jumping, and even the Chaos runes across their hulls still projecting their ghostly blue luminescence.
Yet their ion shield-networks, which were rated to withstand direct bombardments from starship-grade macro-cannons, behaved like thin paper before the oncoming edge, failing to provide even a fraction of a percent of structural resistance.
The bone blade sliced cleanly across the midsections of both cockpits. First, a thin, near-invisible red line manifested across the exterior plating; a microsecond later, the red line expanded exponentially, the cross-sections perfectly level as though they had been machined by a high-precision industrial lathe.
CRACK... CRUNCH!
The structural snapping of metal intermingled with the wet tearing of dense biological tissue.
The upper halves of both knight chassis slid downward along the smooth cuts, exposing the utterly unrecognizable cockpits hidden within.
There were no longer any recognizable human pilots operating inside. The corruptive forces of the warp had long since fused human anatomy and machine architecture into a singular, horrific synthesis. Dark red flesh had rooted into the interior bulkheads like twisted tree roots; the pilot's body had grown directly into the control columns, neural interfaces, and structural framework of the chassis.
Their skin was cast in a putrid, bruised grey-green, their chests bulging with a dense cluster of fluid-filled pustules. Their facial features had entirely liquefied, leaving behind nothing but two turbid eyeballs embedded deep within the meat, still locked in an expression of absolute shock.
Where the spinal greatsword had cut through, flesh and metal parted as one, dark green fluids oozing from the flat incisions.
THUD! THUD!
The severed torsos of the two war machines slammed heavily against the deck, throwing up two dull, metallic echoes. The corrupted flesh within the exposed cockpits continued to twitch with residual neural reflexes, yet the souls of the pilots had been utterly obliterated by the Hive Mind's consensus the exact microsecond the blade had cut through their frames.
Aboard the back of her Helldrake, Luna's breathing abruptly hitched. Her fingers clamped down around her staff by sheer reflex, the color draining completely from her face beneath the shadow of her hood.
Two Chaos Knight chassis.
She had spent half a year utilizing her family's ancestral knight frames as a baseline, personally weaving her sorcery across them. She had sacrificed the souls of over a thousand fanatical cultists to forcibly corrupt these nine war machines. Every single unit was priceless, comprising the absolute core of her tactical hand.
Yet now, they had been casually dissected one by one like soft cheese, falling in under two seconds from drawing the blade to breaching the plating.
Cold sweat seeped into Luna's palms. She had consistently operated under the assumption that Sarah merely specialized in psychic proficiency, and that her close-quarters capability was at best comparable to a standard Magus. She had believed that as long as her knight frames tied her down in close combat while her sorcery wore down her reserves from afar, she could eventually grind her down to absolute zero.
Yet now, clarity hit her: it was not that the adversary's close-quarters parameters were weak; it was that she had not been fighting with serious intent previously.
This magnitude of power, this level of velocity, this precise sharpness that could shear through space itself... If the entity truly intended to execute her, it would likely not grant her enough temporal clearance to utter a single syllable of a incantation.
"Impossible... The array clearly severed her connection to the hive nexus..." Luna muttered in a low register, a trace of imperceptible trembling fracturing her voice beneath the mask.
When she constructed this Spirit-Sealing Array, its primary operational mandate was to block out the Hive Mind's consensus, converting Sarah into a source without a wellspring, a tree lacking roots. Her psychic mass should have depleted with every single expenditure until she was completely dry.
Yet the energy signature flaring before her eyes resembled anything but a dry wellspring. This was the concentrated might of the entire Swarm distilled into a singular blade.
Luna drew a sharp breath, forcibly suppressing the panic seizing her heart. She cautioned herself not to panic; the more violently the opponent erupted, the more truncated the operational window would be. Power of this magnitude could never be sustained indefinitely. As long as she weathered this initial wave, the strategic victory remained hers.
Outwardly, she maintained the supreme arrogance expected of a Champion Sorcerer of Tzeentch, looking down upon Sarah from her high vantage point. Her voice, amplified through sorcerous currents, boomed coldly through the enclosure:
"Trifles. A fleeting brilliance purchased through the life-sacrifices of three Maguses—and you dare display such insolence before me?"
"I shall see precisely how many times you can deliver such a desperate strike."
As she spoke, her voluminous sleeves hung loosely at her sides, but her fingers—shielded beneath the shadow of her cloak—rapidly wove a sequence of complex hand-seals. Ghostly blue sorcerous runes flickered across her fingertips, yet she deliberately suppressed their signatures, preventing a single watt of energy from leaking outward.
This was Tzeentch's Folded-Form Evasion, her absolute ultimate defensive escape technique. Once initiated, it could instantaneously displace her true form to any coordinate within the array, leaving behind an illusion so structurally accurate that even psychic tracking metrics could not differentiate between the two.
Across countless previous hazards, she had relied on this specific maneuver to execute clean extractions. Today, she had zero intention of gambling her life against the acceleration of the opponent's blade.
Beneath the platform, Sarah gripped the spinal greatsword, standing silently amid the burning wreckage of the two war machines. Purple psychic fire continued to roll across her frame, her aura towering like an invincible god of war. Yet only she recognized that her absolute operational limit had arrived.
The structural tolerance of this Chosen chassis was ultimately finite. Peer-level energy was far too tyrannical; even a singular strike behaved like molten magma, charging rampantly through her neural circuitry. She could feel the muscle fibers within her arms snapping millimeter by millimeter, her skeletal framework emitting groans as it buckled under the load, her blood vessels burning as though crowded by a million stinging insects.
Furthermore, following that horizontal slash, the psychic reserves stored within the spinal greatsword had already depleted by half. Calculating her remaining output, she could manage, at absolute most, one final strike.
Only one single slash.
She could either execute Luna, or... Her gaze shifted toward the ghostly blue boundaries of the array.
Sarah raised the weapon. Bracing herself with one hand against the deck and locking her remaining three hands onto the hilt, she brought the heavy spinal greatsword level across her right shoulder. The segmented structural nodes of the blade rippled in wave-like successions, looking as though it were breathing, or drawing in mass for a final release.
She dipped her knees slightly, the musculature of her legs locking tight. The deck plates beneath her boots failed to withstand the terrifying spiritual pressure, fine cracks branching outward like a dense spiderweb. Wherever the fissures spread, the scattered fragments of the destroyed knights sank slightly into the metal floor.
Her violet eyes snapped upward, her gaze crossing dozens of meters to lock squarely onto Luna atop the platform.
Her expression was flawlessly flat—devoid of anger, free of contempt, missing even a fraction of emotional variance. It mirrored the clinical focus of an apex predator pinning a target, cold and utterly focused, carrying an unmitigated intent to harvest life. This was not the struggle of a cornered beast; it was the hunter drawing the net closed.
"Fire! All units fire! Execute her!" Luna felt a primal dread spike through her nervous system beneath that stare, and she barked out the mandate in a shrill register.
The remaining seven Chaos Knights instantly realigned their targeting axes, their volcano cannons, multi-meltas, and plasma weapons roaring in unison. Across the perimeter, the surviving Pink Horrors, Flamers, and mutated cultists swarmed forward, unleashing a saturated downpour of sorcerous bolts, warp-fire, and corrosive streams toward Sarah's coordinates.
The multi-colored offensive interwove into an absolute matrix of lethality in mid-air, possessing more than enough explosive yield to reduce a heavy main battle tank to molten scrap metal.
Yet Sarah remained rooted to the spot, entirely stationary.
The psychic fire enveloping her frame expanded automatically, consolidating into a hemispherical aegis. Every single offensive manifestation that impacted the barrier was either shredded into raw energy or deflected harmlessly across her flanks, failing to touch so much as the hem of her grey robes.
Amid the cascading detonation flashes, her silhouette remained monumentally still, her focus anchored unblinkingly upon Luna.
That unyielding stare caused cold dread to crawl up Luna's spine. She knew she could no longer wait; the internal alarms within her consciousness were screaming in panic. She recognized this sensation—it was the biological precursor to imminent mortality. The adversary was pooling her mass, waiting for the absolute optimal frame to unleash her blade, and Luna held zero confidence that she could absorb a full-throttle strike from that weapon.
Was maintaining the stability of the array important? Unquestionably. Yet regardless of its strategic weight, it could never supersede the value of her own life. After all, the entirety of the Sanctus Gallus line was waiting to ascend to absolute glory under her supreme leadership!
Luna ceased her hesitation. Her fingers snapped closed within her sleeve, finalizing the terminal seal of the incantation.
At that exact microsecond, Sarah moved. The metal flooring beneath her boots collapsed entirely, and her physical form vanished from reality.
"Now!" Luna hissed internally, her psychic reserves pouring down the conduit of the hand-seal. A ghostly blue shimmer flashed across her skin and dissolved; the next millisecond, her silhouette turned translucent and hollow.
Her true form, leveraging the Folded-Form Evasion, had already displaced cleanly to the deep shadows across the opposite sector of the array.
Luna stepped out slowly from behind a Pink Horror, a cold sneer forming across her lips. Attempting to assassinate me? You are still far too green.
She prepared to utter a mocking remark while systematically realigning the array's energy matrices to pin the entity down at the epicenter. Yet as she scanned the quadrants, Sarah was nowhere to be found. She was missing from the floor, absent from the skies above the Helldrakes, and completely untraceable within the crevices of the remaining knight frames.
Where was she?
Luna's heart skipped a beat, a violent tide of raw apprehension seizing her consciousness. She raised her head by pure instinct.
Far above the theater, directly beneath the ceiling of the ghostly blue array, a slender silhouette had ascended to the absolute highest coordinate of the enclosure.
With her back turned to the frantic anti-aircraft fire surging below, Sarah raised the spinal greatsword high with all four arms, the blade vertical, its tip oriented straight down. Purple psychic energy converged frantically along the length of the bone steel, consolidating into a singular pinpoint at the apex—shining with an intensity that forced the eyes shut.
From the absolute inception of the movement, her objective had never been to gamble on whether her blade could pierce through Luna's evasion spell. Her objective was the Spirit-Sealing Array itself, which held her primary consciousness captive.
To execute her evasion maneuver, Luna had stripped away the vast majority of her focus from maintaining the array's structural loops. At this precise millisecond, the barrier was at its most vulnerable threshold.
"Cleft," a cold voice descended from the high dome, light as a falling snowflake.
Yet following that syllable was a slash capable of tearing the sky from the earth.
The spinal greatsword came down with the entirety of its accumulated payload, smashing heavily against the ghostly blue barrier. There was no deafening detonation, no world-shaking explosion. There was merely a deep purple sword-scar that propagated straight down from the apex contact point, resembling a diamond scalpel scoring a sheet of fragile glass.
CRACK!
A crisp, brittle snapping sound echoed through the chamber. A massive structural fracture ran completely through the entire face of the array's boundary.
The surrounding ghostly blue runes began to flash erratically before shattering into fragments, the energy circuits sustaining the enclosure collapsing into unmitigated chaos. Deprived of Luna's absolute focus to reinforce its loops, the already unstable Nine-Sided Spirit-Sealing Array finally entered a state of terminal collapse under a strike saturated with the full weight of the Frost Dragon.
The fractures spiderwebbed across the four quadrants, growing denser and deeper with every millisecond. Standing within the shadows, Luna stared up at the sword-wielding silhouette perched at the dome, watching the progressive shattering of her masterwork as the face beneath her hood turned completely ash-white.
