Beneath the Crumbling World
🕑 Added 2025-04-14 03:30:02 +0000 UTCThe tunnel groaned.
Cassian heard it first a bone-deep vibration that rippled through his power armor. Then came the thunderous crack. The walls trembled, dust raining from the ceiling as fractures split across the metal and stone like veins. The maintenance tunnel moaned, ancient supports straining under invisible pressure. Cassian didn’t need Warp senses to know what was happening.
The daemon was coming.
"Move!" Cassian barked, voice amplified by his armor.
Magos Ferran stumbled forward, servos whining as his augmented frame struggled to keep pace. The Magos clutched the salvaged STC fragment to his chest like a sacred relic, mechadendrites wrapping protectively around it. Behind them, the tunnel shuddered again, a deafening boom echoing through the darkness.
Cassian spun, raising his Godwyn-Pattern Bolter, sweeping the shadows. The tunnel stretched endlessly into darkness, the only light coming from the glow of Ferran's optics and Cassian's helmet display. Something slithered in the dark.
A wet, rasping sound.
Cassian fired. The bolt round exploded in the gloom, the muzzle flash revealing a twisted figure scrambling along the wall. Pallid flesh stretched tight over elongated limbs. Mutant. The creature screeched, lunging forward, only to be torn apart by a second bolt round.
The tunnel groaned again, the floor lurching beneath their feet. Ferran cursed in binary, skidding as he nearly lost his footing.
"The structural integrity is failing!" Ferran hissed, his vox crackling with distortion. "We must expedite our retreat!"
"No shit!" Cassian growled, pulling the Magos forward.
The darkness pressed in, oppressive and heavy. Cassian's mind tingled with the familiar prickle of Warp intrusion. He reinforced his mental barriers, gritting his teeth as whispers scratched at the edges of his thoughts. The Greater Daemon’s presence loomed like a storm on the horizon, its influence warping reality itself.
Suddenly, the tunnel ahead erupted in movement. Dozens of eyes glimmered in the dark, reflecting the dim light. Cassian cursed, raising his Bolter. Cultists. Emaciated figures with tattered robes and crude weapons surged forward, screaming in praise of dark gods.
"Hold them off!" Ferran snapped, deploying a trio of combat-servitors from his pack. The metal-clad constructs stomped forward, laying down suppressive fire with their autoguns. Cassian joined the fray, squeezing the trigger of his Bolter.
The first cultist exploded in a shower of gore. The second stumbled, limbs torn apart by a burst of shrapnel. A mutant lunged from the side, claws scraping against his power armor, only for Cassian to slam his armored fist into its skull, caving it in.
The tunnel rumbled again, louder this time. Cassian glanced back, his helmet's auspex picking up seismic activity. The daemon was close. Too close.
"Ferran, we need to move!"
The Magos fired a burst from his integrated lascarbine, scorching a cultist to ash. "Almost through! The exit is two hundred meters ahead!"
Cassian didn't have time to respond. The wall beside him exploded outward, a massive, bloated mutant bursting through. Its flesh was pockmarked with sores, its eyes burning with unnatural light. Cassian raised his Meltagun, firing point-blank. The creature shrieked as its torso disintegrated, molten slag dripping from the wound.
They pushed forward, Cassian cutting down anything that got in their way through his chainsword. The tunnel continued to collapse behind them, debris raining down, choking the air with dust and ash. Ferran stumbled, nearly dropping the STC fragment, but Cassian caught him, dragging the Magos forward.
Then, they saw it in the distance.
The exit to the maintenance tunnels.
A massive bulkhead door stood partially open, warp atmosphere streaming in from the other side. Beyond it, freedom — or at least the surface. Cassian shoved Ferran through first, turning to cover their retreat. Mutants and cultists swarmed after them, shrieking in rage. Cassian fired his last bolt round, then switched to his Meltagun. The weapon hissed, vaporizing a dozen enemies in a single blast.
Then the tunnel roared.
A deafening explosion rocked the ground, the walls splitting apart. Cassian sprinted, vaulting through the bulkhead just as the tunnel collapsed behind him, sealing the horrors within.
They were out.
Cassian collapsed to his knees, gasping for air. Ferran stood beside him, cradling the STC fragment like a newborn. Above them, the sky churned with unnatural colors. The daemon was looming.
But they had survived.
—-
The surface of the corrupted world churned with unnatural energies.
The sky overhead was a swirling bruise of colors that shouldn’t exist, roiling with alien hues that seemed to twist reality itself. Behind him, Magos Farron emerged, his mechadendrites scraping against the broken ground as he hauled himself free. Dust and ash clung to their armor. Every step felt heavier, the weight of the daemon’s gaze pressing down on Cassian’s mind like a vice.
“Farron,” Cassian rasped, steadying himself. “We can’t stay here.”
“No. We cannot.” Farron’s synthetic voice carried a faint tremor. His lenses swept across the horizon, processing the chaotic landscape, before settling on Cassian. “The daemon’s presence is distorting the environment. The warp energies—”
“I know.” Cassian grimaced. The daemon’s whispers gnawed at the edges of his thoughts, slithering through his mental defenses.
Power.
Knowledge.
Fate is yours to shape.
Accept the gift.
He clenched his jaw, forcing the voice out, but it was still there.
A distant rumble made them both turn. In the horizon's fractured light, a massive silhouette loomed. The greater daemon’s form distorted the air around it, an incomprehensible mass of shifting limbs, crystalline eyes, and twisting smoke. It moved with an eldritch grace, each step shaking the ground. Cassian could barely look at it. Every time his eyes tried to focus, its form shifted. A titanic shape of ever-changing color, its very presence corroding reality.
Magos Farron’s mechadendrites flicked nervously. As he started calculating their survival and started looking at the dataslate for anything that could help them.“We are exposed.”
“No shit.” Cassian scanned the horizon, heart racing. There was no cover. The daemon’s size meant it couldn’t move quickly through the wreckage, but once it fixed its gaze on them, nothing would stop it. His mind scrambled for options. The ship was too far, and leading the daemon there was suicide.
Farron knelt and pressed a hand against the ground. His mechadendrites burrowed into the soil, data streaming into his augmetics. “There is… a sub-structure beneath us.”
Cassian narrowed his eyes. “Another tunnel?”
“Not quite. Structural readings indicate an old service shaft. It leads to a secondary power relay that supplies the maintenance tunnels with its power.” The Magos looked up, his lenses glowing softly. “It may offer temporary concealment.”
“Temporary isn’t good enough.” Cassian swore under his breath. “Any way we can lose it completely?”
Farron hesitated, then flicked through his internal systems. “A distraction.”
Cassian frowned. “What kind of distraction?”
The Magos tilted his head. “A controlled plasma discharge. The power relay beneath us still holds residual energy. I could overload it remotely.”
Cassian glanced over his shoulder at the looming daemon. It hadn’t seen them yet, its gaze fixed on something unseen in the distance. “Won’t that just draw it to us?”
“Only briefly.” Farron’s mechadendrites flexed. “It will destabilize the ground, creating enough noise and chaos to mask our escape. But we must move quickly.”
Cassian exhaled slowly, feeling the daemon’s presence pressing against his mind. It was risky, but they did not have much choice.
The whispers grew sharper.
Power… Knowledge… I see you. I see what you seek. Accept. And survive.
He pushed the voice away. “Do it.”
Farron’s mechadendrites clicked and hissed as he interfaced with the crumbling earth beneath them. Cassian scanned the horizon, gripping his bolter tighter. The daemon’s massive form shifted, its many eyes blinking in unison. It was searching.
“Almost… there.” Farron’s monotone voice wavered slightly. “Now.”
The ground beneath them rumbled. A deep, resonant hum pulsed through the air as the power relay detonated. The explosion was distant, but the ground trembled violently. From their vantage point, Cassian saw a plume of light burst skyward, followed by a shockwave of dust and debris.
The daemon turned, its colossal head swiveling toward the disturbance. It let out a sound that was less a roar and more a warping of reality itself — a deep, resonant howl that made the air quiver and Cassian’s teeth ache.
“Move!” Cassian grabbed Farron’s arm, dragging him toward a nearby ridge. The Magos stumbled, his mechanical limbs struggling to keep pace. Behind them, the daemon’s form twisted, its gaze fixed on the blast. For now, they were invisible.
They ran. The landscape blurred, twisted shapes and shadows clawing at their heels. Cassian felt the daemon’s whispers fading, but not gone.
As they reached the ridge, Cassian glanced back one last time. The daemon loomed in the distance, its colossal form slowly turning away. For now, they were safe.

The journey back to the ship was slow. The ground beneath Cassian’s boots felt more solid than before, though whether that was a comfort or a deception, he wasn’t sure. The weight of his power armor pressed down on him, the Godwyn-pattern boltgun hanging heavy across his chest, its ammo empty.
Beside him, Magos Farron moved with him, the clinking of his augmetics filling the silence. His robes were torn and dirtied, the crimson fabric stained with grime and ichor. Still, the Magos kept pace, the faint hum of his servo-arm accompanying every step.
For a while, neither of them spoke. The air was thick, oppressive in its silence, and even the distant wailing of the wind sounded more like a pained whisper than any natural breeze. Cassian kept his eyes forward, scanning the horizon, his mind still replaying the daemon’s voice. The promises. The threats. He pushed it down, locking it away behind mental walls that felt more fragile than ever.
Farron broke the silence first. “You’re quiet.”
Cassian glanced at him. “Isn’t that normal for me?”
“Hm. Yes. But this is… different.” The Magos tilted his head, his bionic eye whirring softly as it adjusted its focus. “I’d hypothesize that nearly dying in a collapsing tunnel while being chased by mutants and eldritch horrors might have something to do with it.”
Cassian snorted. “Fair guess.”
They walked a few more steps before Farron spoke again. “You handled yourself well back there.”
Cassian raised a brow. “Was that a compliment?”
“Merely an observation.” Farron’s mechadendrites twitched.
Cassian chuckled under his breath, the sound dry and humorless. He shifted the weight of his meltagun, letting it rest against his hip. The trek back to the ship felt longer than before, the landscape shifting subtly in ways he couldn’t quite pin down. The ground looked more fractured, the sky a deeper shade of crimson. Or maybe he was just imagining it.
“So,” Cassian said after a while, “that STC… you think it was worth it after all that trouble and near deaths we had?”
Farron’s eyes brightened — both the organic and the mechanical. “Worth it? It’s a fragment of the past, a glimpse into the sacred knowledge of the Omnissiah’s design. Even this small piece holds secrets that could alter the course of Mechanicus doctrine.” He paused, glancing at Cassian. “Not that you would understand.”
Cassian smirked. “You’re right. I wouldn’t.” While showing the badge he got from mechanicus
Farron let out a sound that could have been a laugh, or perhaps just a static discharge. “Still… even you must recognize the significance. Nanites capable of enhancing the human body — strength, reflexes, durability — and integrating with augmentations seamlessly. It’s beyond anything the Mechanicus currently possesses.”
Cassian shrugged, though he felt the weight of the words. “Doesn’t mean much if we die before we get off this rock.”
Farron huffed. “Pragmatism. One thing that is keeping us alive.”
Cassian shook his head, a small smirk tugging at his lips. The silence stretched again, more comfortable this time. The planet’s atmosphere weighed down on them, but at least the horrors of the tunnels were behind them.
After a while, Farron spoke again, his tone more subdued. “You saw it, didn’t you?”
Cassian tensed. “Saw what?”
“The… presence.” The Magos shifted slightly, his mechadendrites curling inward. “I felt… something. A pressure. A weight on the mind. I lack the sensitivities you possess, but even I could sense it.”
Cassian kept his gaze forward as he sighed. “Way to ruin the mood magos.”
Farron’s bionic eye flared at that “It was an important question.”
Cassian replied after a moment “Yes, I did feel that presence in my mind.”
They walked in silence after that, the ruins slowly giving way to the familiar desolation surrounding the ship. The closer they got, the more the weight on Cassian’s chest lifted. The ship wasn’t much, but at least it offered safety in a world gone mad.
When the battered hull finally came into view, Cassian let out a breath he hadn’t realized he’d been holding. The ship stood like a lone sentinel against the chaos, its worn frame a reminder that survival was possible.
As they approached, Farron glanced at Cassian. “Next time,” he said, “try not to collapse the tunnels.”
Cassian smirked. “I just hope there would not be a next time. I am too tired of this bullshit.”
The ramp hissed open, the ship’s interior a blessed reprieve from the horrors outside. As the door sealed behind them, Cassian leaned against the bulkhead, closing his eyes for a moment. The daemon’s whispers still lingered, faint and distant, but for now… they were quiet.
Farron moved toward the ship’s console, his mechanical fingers tapping against the controls. “I’ll start analyzing what we recovered.”
Cassian pushed off the wall, his body aching with every movement. “You do that.”
As he made his way toward his quarters, he cast one last glance over his shoulder. Farron was already lost in his work, the soft glow of the console illuminating his face.
