At the exact structural millisecond that undercurrents were surging through the lower decks of the Gemstone, the atmosphere within the Nine-Sided Spirit-Sealing Array beneath Castle Sanctus Gallus had also grown razor-sharp.
Luna floated high above the platform, the sorcerous staff in her hand trembling slightly as ghostly blue runes cycled rapidly around her frame, yet her internal state was at an absolute nadir.
The plan was completely compromised.
According to her original calculations, the narrative should have seen Dominic uncover the Genestealer secret, fracturing his alliance with Lynn entirely. The two would engage in an internecine military conflict, leaving her to comfortably reap the strategic rewards.
Yet the abrupt intervention of the Nurgle fleet had fundamentally shattered that momentum.
With the void engagement fully underway, Dominic was hopelessly overstretched. Far from calling Lynn to account, he would likely have to rely on ground-side assets for tactical support just to survive.
Furthermore, time within this array was compressed a hundredfold; for every hour that ticked away in the material universe, a mere thirty-six seconds elapsed within the perimeter. She had initially intended to leverage this temporal excess to slowly grind Sarah down to absolute zero, waiting for the external drama to reach fruition.
Yet now, the script outside had veered completely off-course, while Sarah's operational parameter inside was growing increasingly stable.
The psychic resilience of this Chosen Tyranid entity far exceeded her preliminary assessments. Despite the nine Chaos Knights rotating their long-range artillery sweeps—even while flagrantly sandbagging—and bombarding the position for so long, the adversary's psychic mesh defenses had merely dimmed a fraction, betraying zero signs of structural collapse.
If this dragged on any further, throne alone knew what operational variables would manifest.
The lips beneath Luna's mask compressed into a razor-thin line, a flash of absolute malice cutting through her eyes. She could no longer afford to wait. Since the external chessboard had lost its alignment, she would initiate a breakthrough from within.
If she could decisively liquidate Rena's primary consciousness, the entire Tyranid organizational framework across Brevis would suffer terminal shock. The Purge Cult within the undercity would fracture, the winter-legions across the ice sheets would lose behavioral control, and Lynn would effectively have his most formidable arm severed.
When that juncture arrived, even if Dominic failed to press him, she held absolute confidence that she could swing the overall balance back into her favor.
"Did you honestly believe that by shrinking into a turtle shell, I would be incapable of executing you?" Luna sneered in a low, cold register, driving her staff heavily against the stone.
The ghostly blue sorcerous light surged along the nine-sided geometry of the array. The nine Chaos Knights, which had previously maintained a measured, slow-tempo bombardment, instantly froze in their tracks.
The next millisecond, the runes blanketing their massive hulls flared with blinding intensity.
"All units, close-quarters vanguard advance," Luna's cold voice resonated through every corner of the array. "Grind her to ash."
The nine Chaos Knights ignited their rear thrusters simultaneously, their massive, heavy frames slamming against the deck plates with a deafening roar.
The three knights anchoring the vanguard vanguard-line spun up their Reaper Chainswords first, the high-speed rotation of the teeth generating an ear-splitting shriek. The units flanking the formation raised their Thunder Strike Gauntlets, arcs of raw electricity crackling violently across the metal fists, while the rearguard elements discharged their shoulder-mounted ordnance in unison, leveraging multi-meltas and plasma rays to suppress the survivors at the center to facilitate the close-quarters advance.
This was no longer the cautious, skirmish-style sandbagging of the previous hours; every single strike was calculated to be terminal, backed by an unmitigated ferocity intended to tear Sarah into unrecognizable pieces.
At the epicenter of the array, Sarah suspended herself in mid-air, her four arms extended symmetrically as layers of psychic mesh unfurled across her forward vector.
Watching the encroaching knight chassis thundering toward her, her violet eyes betrayed not a single shred of terror. Instead, a flash of absolute clarity filtered through her consciousness.
They were finally committing their true strength.
The adversary had gone to extraordinary logistical lengths to construct this Nine-Sided Spirit-Sealing Array, severing the Hive Mind's consensus and slowing the temporal flow, and it was certainly not for mere amusement. Luna undoubtedly possessed a mechanism to leverage this array to heavily compromise or entirely liquidate her consciousness.
Rather than being captured by the enemy and converted into a leverage point against Lynn and the Swarm, she would gladly initiate terminal self-termination.
The Tyranid race recognized zero precedent for capture!
Sarah slowly retracted her four arms, pressing her palms together in a central posture before her chest. A pale violet psychic luminescence blossomed from her frame, growing increasingly brilliant and incandescent.
The psychic reserves within her form began to contract at an exponential velocity, preparing to detonate her entire payload in a single, terminal expansion. While a self-detonation would inflict severe trauma upon her primary consciousness—requiring a prolonged epoch of dormancy to reconstitute—it would at least deny her form to the enemy, ensuring she never became a chip to threaten Lynn's position.
Yet at the precise microsecond her psychic mass was about to breach critical parameters, a deeply familiar voice suddenly cascaded down the system-linked channel, driving straight into the absolute depths of her consciousness:
"Sarah, I have arrived."
The voice was exceptionally quiet, flawlessly steady, carrying that same grounding, absolute security that had defined countless engagements they had fought side-by-side.
Sarah snapped her eyes open. The absolute finality within her gaze melted away instantly, and the corners of her mouth arced into a faint, yet profoundly genuine smile.
He had arrived.
The next millisecond, the three remaining Genestealer Maguses flanking her position moved in perfect synchronization.
These three high-tier hybrids, who had spent the entire descent and subsequent bitter engagement gritting their teeth to sustain the domain despite their psychic reserves being utterly depleted, did not hesitate for a single fraction of a second. They extended their arms toward one another.
Grey-white bone spikes burst violently from their palms, driving into each other's flesh like parasitic vines. Muscle, blood vessels, and neural pathways fused at terminal velocity under the deliberate pull of psychic energy, their skin and skeletal systems emitting a sickening, grinding squelch as they morphed.
The two Maguses on the left flank began to systematically liquefy, dissolving into a viscous mass of organic tissue that washed over the tallest Magus at the center like a fluid current. The biomass contracted and reshaped with frantic speed, bone structures snapping sharply as redundant tissue was reabsorbed. The core spine and sternum expanded outward, elongating until they consolidated into a bizarre, person-height flesh altar.
The altar was cast entirely in dark purple, its exterior blanketed in dense, fine chitinous scales. Three twisted, organic arms spiraled up from the foundational base, converging at the apex to form a deep, hollow receptacle.
This was pure, unadulterated Tyranid xenos aesthetic. Cruel, highly efficient, carrying the primal, raw shock of total biological synthesis.
A tide of formidable psychic energy, far eclipsing the combined maximum output of the three original Maguses, violently erupted from the flesh altar!
A column of purple psychic light shot straight into the dome, smashing heavily against the ceiling of the Nine-Sided Spirit-Sealing Array. The entire enclosure shuddered violently, the ghostly blue runes flickering erratically like candle flames caught in a tempest, threatening to snuff out at any second.
"This is bad!"
Perched atop her wyvern, Luna's expression warped violently, her heart skipping a beat. She had initially anticipated a desperate, terminal counter-offensive from the entity, but she had never envisioned the adversary would leverage the biomass of three high-tier Maguses to forcibly engineer a flesh altar!
This specific psychic magnitude was actively threatening to breach the tolerance thresholds of the array itself!
"Focus fire! Concentrated fire immediately!" Luna barked out the mandate, her staff whipping through the air frantically as she launched successive bolts of ghostly blue sorcery toward the center. "Disrupt her! Under no circumstances can she be permitted to complete the ritual!"
In an instant, an absolute saturation of firepower was unleashed.
Multi-melta arrays scorched the dim space into blinding white, and shoulder-mounted missiles shrieked downrange trailing plumes of exhaust fire. Plasma rays and Tzeentchian warp-bolts interwoven into an impenetrable mesh of absolute lethality, descending toward Sarah and the flesh altar at the center of the array.
The two vanguard Chaos Knights had already closed the distance to within ten meters of the altar, their Reaper Chainswords coming down with a whistling roar. Their Thunder Strike Gauntlets smashed downward wrapped in crackling electricity, their trajectories locked squarely onto Sarah's skull.
The offensive was incredibly swift and remorseless, boxing out every conceivable vector of evasion.
Yet Sarah operated as though she were completely oblivious to these lethal vectors. She stepped forward with measured pace toward the pulsating flesh altar, her violet eyes locked strictly onto the receptacle at its apex.
Everything around her was beginning to slow down.
No—it was not that reality was slowing down; it was that she was moving faster.
The exact millisecond the psychic column had impacted the array's boundaries, the localized energy liberated by the altar had temporarily fractured the regional temporal flow. The overarching tenfold deceleration of the array remained intact across the theater, but within this microscopic perimeter encompassing her and the altar, the temporal vector had been forcibly dragged back to match the normal parameters of the external universe.
Between this stark contrast of velocity, every single incoming offensive manifestation converted into slow-motion frames within Sarah's vision.
The individual teeth of the chainswords rotated with crystalline clarity; the exhaust trails of the missiles dragged sluggish luminescent marks through the air; the sorcerous bolts drifted forward like a highly viscous fluid.
She reached out her hand, wrapping her fingers around a section of bleached bone hilt protruding from the apex of the altar. It was a hilt forged from the fused and tempered spinal columns of the three Maguses, its surface still retaining the warm, pulsing temperature of living flesh.
Sarah's five fingers tightened, and she ripped the weapon outward with a violent heave!
HUM!
A deep, resonant sword-hum vibrated through the entirety of the array.
A massive, four-and-a-half-meter spinal greatsword was extracted entirely from the heart of the flesh altar. The blade was forged from three complete vertebral columns fused into a singular line, the segments glowing with a pale violet psychic aura. The edges of the blade were lined with dense, bone-chitin serrations, and the crossguard manifested curved bone spikes that mirrored unfurled wing membranes.
A tempest of absolute psychic wind exploded outward with Sarah as its epicenter!
The purple shockwave swept across the four quadrants, causing her robes to snap violently in the wind. Every single offensive manifestation that had closed within her immediate perimeter was violently shattered and dissolved the exact microsecond it made contact with the psychic storm, failing to project even a fraction of a percent of residual impact against the altar.
The two Chaos Knights that had spearheaded the charge were violently thrown back by the psychic backdraft, their heavy, multi-ton chassis sliding dozens of meters across the deck, plowing two deep, jagged furrows into the reinforced metal flooring.
Sarah held the spinal greatsword in a firm grip, slowly raising her head.
Within her violet eyes, psychic fire was rolling in near-material currents.
The game had just changed its protagonist.
