The ship's silence was a comfort Cassian hadn't expected. It gave him space to think, to focus. Power armor locked around him like a second skin, each servo shifting with his movements, but his attention was elsewhere. He knelt in the dim light of the ship's hold, eyes half-closed, pushing his mind into that razor's edge of awareness. The Warp pressed faintly against his thoughts — a constant, subtle pressure. He reinforced his defenses, weaving his will into a barrier. Each time felt more natural.
Across the hold, Magos Farron worked in silence. The Tech-Priest moved with practiced manner, mechadendrites snaking out to adjust tools and probe cogitator interfaces. He muttered binharic cant to himself, soft bursts of code-song filling the air. Cassian kept an eye on him. The Magos had been oddly quiet since their discovery. Focused. Cassian knew the look — he'd seen it before, in men who thought they were on the edge of something monumental.
"Will the tools be enough?" Cassian asked quietly.
Farron glanced over, the red glow of his optical implants cutting through the dimness. "They will suffice. The ruins… they are old, but not ancient. I have compiled what schematics I could from the city's archives. There will be mechanisms. Interfaces. The Omnissiah guides my hand."
Cassian said nothing. Tech-lust was creeping into Farron's tone — subtle, but there. The STC had its hooks in him already. Good. If Farron was invested, he'd work harder.
The Magos turned back to his preparations, mechadendrites curling around a collection of data-spikes and interface modules. Cassian shifted his weight, feeling the slight drag of his depleted bolter mags against his hip. His Godwyn-pattern bolter had precious few rounds left. The melta was better, but not by much. Supplies were running thin.
He closed his eyes again, pushing everything else aside. The Warp thrummed faintly at the edges of his mind, like distant whispers carried on the wind. He pushed back, reinforcing the walls of his thoughts. It felt more solid now. The pressure receded. Good enough.
"Time to move," Farron said. The Tech-Priest's voice was clipped, eager.
Cassian stood, rolling his shoulders, armor humming softly as it adjusted to his movements. He followed Farron into the corridor, the ship's bulkhead sealing behind them with a heavy hiss.
The city was as dead as before. Silent. They moved quickly, Cassian taking point, Farron just behind him. The Tech-Priest moved silently, mechadendrites holding a flickering dataslate as he cross-referenced the city's layout. Their path led them to the maintenance tunnels — dark, damp, and reeking of rust and decay.
Cassian felt it almost immediately. A pressure. Not physical. Psychic. The Warp hummed faintly at the edges of his mind, like a distant whisper. He tightened his grip on his bolter and pushed the sensation away.
Farron didn't seem to notice. The Tech-Priest moved steadily ahead, casting the occasional glance at his dataslate. Cassian followed, eyes scanning the shadows. The tunnel stretched out ahead of them, dark and silent, the walls slick with moisture. Every footstep echoed.
Something shifted in the darkness. Cassian snapped his bolter up, scanning the shadows. Nothing. Just darkness.
Farron paused, glancing back. "Problem?"
"Keep moving," Cassian said quietly. He reinforced his mental barriers again, feeling the pressure lessen slightly.
They pressed on. The tunnel stretched out before them, twisting and turning beneath the city. The walls felt closer. Cassian felt it again — a weight against his mind, faint but steady. Something was watching. He tightened his grip on his bolter and pushed the feeling away.
"Almost there," Farron said softly. His voice was tight. Eager.
Cassian stayed silent, eyes scanning the darkness. Whatever was watching, it hadn't moved.
They reached a rusted bulkhead, half-buried in debris. Farron moved forward, mechadendrites snaking out to probe the mechanisms. Cassian stood watch, bolter raised.
The pressure grew stronger. Closer. He reinforced his barriers again. The feeling lessened, but it didn't vanish. He glanced at Farron. The Magos worked quickly, fingers dancing over the controls.
Hurry up, Cassian thought.
The lock clicked. The bulkhead slid open with a low groan. Beyond, the tunnel stretched on, darker and colder. Farron stepped through, Cassian right behind him.
They moved deeper into the ruins. The pressure didn't fade. Cassian could feel it — watching, waiting. He pushed it away and kept moving. Whatever was down here, they'd deal with it when the time came.
For now, survival came first.
---
Cassian felt first—a ripple in the air, cold and sharp, brushing against the edges of his mind. It wasn't the usual Warp pressure he'd grown accustomed to; this was more invasive, a probing presence, light as a whisper. His mental barriers flared in response, the invisible walls of his will slamming shut. The pressure withdrew but lingered, brushing against the edges, testing.
"Keep your eyes open," Cassian muttered, his voice barely carrying over the echo of their footsteps.
Faron glanced back, his mechadendrites twitching. "My auspex readings detect anomalies, but nothing conclusive."
Cassian didn't respond. Words wouldn't help. He pushed ahead, stepping through a rusted doorway into a wider section of the tunnels. The walls stretched upwards into darkness, pipes running along the ceiling like veins. Water dripped from somewhere, the sound echoing endlessly.
Then he heard it.
A wet shuffle.
Cassian's bolter snapped up, the barrel sweeping across the tunnel. Faron froze, mechadendrites coiling defensively. The sound came again—a squelching drag, like flesh scraping against stone.
Cassian tensed. "Move."
They pressed forward, the tunnel narrowing into a tight passage. The walls felt closer, the darkness deeper. Each step echoed unnaturally, as if the tunnel were breathing with them.
Another sound. Closer this time.
Cassian raised his bolter. The lumen on his armor flared, cutting through the darkness—and something moved.
It lunged from the shadows, pale flesh glistening in the light. Cassian barely had time to react before it was upon him, a tangle of limbs and claws. He fired, the bolter's roar deafening in the confined space. The creature exploded in a spray of black ichor, limbs spasming as it collapsed.
Another shriek echoed through the tunnel. Then another.
"Faron, prepare for engagement!" Cassian barked.
The Magos responded immediately. One of his mechadendrites uncoiled, revealing an Omnissian axe—a formidable weapon combining a power axe with a built-in volkite blaster. Another mechadendrite extended forward, its manipulator unfolding to reveal a phosphor serpenta, a compact yet potent firearm favored by the Adeptus Mechanicus.
The mutants emerged from the shadows—hunched figures with twisted limbs and grotesque features, their eyes glowing with malevolent light. They crawled along the walls and ceiling, their movements erratic and jerky.
Cassian fired his bolter, each shot reducing a mutant to a lifeless heap. Beside him, Faron advanced with preparation. The volkite blaster on his Omnissian axe emitted a searing beam of energy, incinerating a mutant in an instant. With a swift motion, he swung the axe, its power field cleaving through another abomination with ease.
A mutant leapt from the ceiling, aiming for Faron's exposed flank. Without turning, the Magos's phosphor serpenta discharged, the bright phosphor shot striking the creature mid-air, engulfing it in flames. The mutant screeched as it writhed on the ground before falling silent.
Cassian noted Faron's efficiency but had no time to dwell on it. The mutants were relentless. One managed to get close, its claws scraping against Cassian's armor. He drove his gauntleted fist into its face, feeling the crunch of bone, then finished it with a point-blank bolter round.
The Warp pressed against his mind. Cassian felt it—a whisper, faint and cold. He shoved it away, reinforcing his mental barriers. The pressure grew stronger. A voice, smooth and patient, slid into his thoughts.
*Why resist?*
Cassian gritted his teeth. He pushed the voice away and kept moving. The tunnel twisted and turned, each step dragging them deeper into darkness. The mutants seemed endless, each corner hiding another horror. Faron moved beside him, his mechadendrites a blur of motion, weapons firing with mechanical efficiency.
They reached a rusted bulkhead, half-buried in debris. Cassian shoved it open, metal screeching. Magos closed it shut with plasma as roars of mutants behind them echoed. This would bring them time. Beyond, the tunnel stretched on, darker and colder.
The tunnel stretched into darkness. Cassian felt the shift in the air before he saw it — the oppressive weight of something old, powerful, and waiting. His bolter swept the shadows as he advanced, Faron close behind, the Magos's mechadendrites twitching in anticipation.
They emerged into a vast chamber. The air was colder here, the darkness heavier. Cassian's armor sensors flickered, momentarily disrupted. His helmet's lumen beam cut through the gloom, revealing a space unlike the tunnels behind them. The walls were smoother, almost polished, the metal dark with age but untouched by rust. Ancient mechanisms lined the chamber's perimeter, their forms half-buried in dust and debris.
And there, at the heart of it all, stood the STC.
The structure loomed before them — a monolith of dark metal, its surface covered in ancient sigils and Mechanicus script. It stood twice Cassian's height, a construct of blackened steel and brass, its form both angular and elegant, as if crafted by hands that understood both art and function. Dim red lights flickered across its surface, pulsing faintly like a dying heartbeat. The floor beneath it was marked with a circular pattern of runes, their meaning long forgotten, but the air hummed with power.
Cassian exhaled slowly. "Is that…"
"Yes." Faron's voice was barely a whisper, reverent and tinged with awe. The Magos stepped forward, mechadendrites fanning out around him. "A Standard Template Construct. Praise the Omnissiah."
Cassian stayed close, bolter raised. "Can you access it?"
Faron moved eagerly, his mechadendrites curling around the STC's interface ports. His auspex chimed softly, scanning the structure as his fingers danced across a data-slate. One mechadendrite extended a diagnostic probe, its tip sparking as it connected with the ancient machine. The chamber filled with the soft hum of awakening systems, long-dormant mechanisms grinding to life.
"The machine spirit is ancient, but intact," Faron murmured. "I will attempt communion."
Cassian watched as the Magos intoned a low binharic chant, his voice resonating through the chamber. The STC responded, its lights flaring brighter, casting long shadows across the walls. A low vibration coursed through the floor, and the circular runes beneath them glowed faintly.
Suddenly, a screen flickered to life on the STC's surface, lines of ancient code scrolling past. Faron's optics whirred, translating the data faster than Cassian could comprehend.
"Remarkable," Faron breathed. "This… this is beyond anything I've encountered. The STC's primary function revolves around a nanite forge. These medical nanites… they are designed to enhance biological hosts for better immune system, They adapt, assimilate any diseases and strengthen the host."
Cassian's heart quickened. "You're saying this could be used to… improve someone?"
Faron nodded slowly. "Yes. Theoretically it is possible as there is also a program here for combat purposes. A human could achieve levels of augmentation previously deemed impossible without risking rejection. And these nanites are self-replicating — a single batch could be used indefinitely, provided the machine spirit is placated."
Cassian stared at the flickering display. This changed everything. A weapon, a tool, a shield — a path to survival in a galaxy that sought to crush him at every turn.
Faron's fingers clicked across his data-slate, unlocking deeper layers of the STC's archive. The chamber's hum grew louder, the runes on the floor pulsing in time with the machine's awakening.
But something else stirred.
Cassian sensed something — a whisper against the edges of his mind, cold and sharp. The shadows at the chamber's edges darkened, lengthening unnaturally. The air grew heavy, thick with the scent of ozone and copper. He clenched his jaw, reinforcing his mental walls as the presence pressed against him.
You seek power… The voice slithered through his thoughts, smooth and patient. Why resist?
"Something's wrong." Cassian stepped back, bolter snapping to his shoulder. "Faron, shut it down."
The Magos ignored him, enthralled by the STC's secrets. "Almost there… the access protocols are ancient, but I can—"
The chamber shuddered. Metal groaned as unseen forces twisted the air. The lights on the STC flickered, and the runes beneath them flared bright crimson. Cassian's armor sensors screamed warnings.
From the darkness, a shape began to coalesce. Massive, twisted, and terrible, it unfolded from the shadows like a nightmare given form. Its form shifting and writhing, a mass of eyes and tendrils, wings folding around a body that refused to stay still. Its presence pressed against Cassian's mind, seeking cracks in his defenses.
You cannot hide, little mortal…
The chamber trembled as the daemon's laughter echoed through the air. Stones cracked and fell from the ceiling, and the tunnels behind them began to crumble. The STC's lights pulsed frantically, and the nanite forge whirred louder, almost panicked.
The Magos tore his mechadendrites free from the STC, taking a huge chunk of it sparks flying. The chamber buckled, the floor cracking beneath them.
Cassian locked eyes with Faron. "Run."
The chamber collapsed into chaos.
