The Siphon Code: Cocytus Prime

The cold on Cocytus Prime didn’t just bite; it crystallized.

It was a predatory, unyielding force that drifted down from the upper spires of the Gliese Consortium’s corporate hubs, settling into the lower service trenches like a heavy, frozen fog. Here in the Permafrost slums, the atmosphere wasn’t merely gas—it was a weaponized byproduct of heavy industry, thick with artificial ice-storm data and chemical pollutants that froze the moment they touched the corrugated alloy walls. Neon signs from distant, low-tier noodle stalls and black-market cyber-clinics bled sickly hues of magenta and cyan through the churning steam, casting long, distorted shadows across the metal corridors.

Silas leaned heavily against the freezing wall of a service tunnel, his breath blooming in ragged, violent plumes of white. Each exhale felt like throwing a handful of glass shards into the air; each inhale tore at his lungs. Inside his chest, his heart labored in a slow, agonizing rhythm that felt dangerously close to stopping.

He was entirely, terrifyingly empty.

The escape from the Consortium’s orbital security grids had been a disaster of narrow margins. To get their stolen shuttle past the automated scanning arrays, Silas had been forced to bleed himself nearly dry, flooding the ship’s dampener coils with his unique, anti-Siphon blood to mask the massive, volatile energy signature radiating from Julian. He had pushed his body past its physical limits, draining his specialized internal reservoirs until his bone marrow screamed. Now, the bill for that desperate gamble had come due.

Without his anti-Siphon blood to regulate his core temperature and fuel his cellular regeneration, Silas’s natural defenses were entirely shot. The sub-zero plunge of the undercity was invading his system unchallenged. His limbs felt less like muscle and bone and more like poured lead. His vision blurred at the edges, a creeping dark frost threatening to swallow his consciousness entirely. He could feel his blood pressure cratering, his pulse fluttering weakly beneath his collar like a trapped bird. If he didn’t get specialized medical stabilizers—something to aggressively stimulate his body’s hematopoietic system and force his marrow to kick-start blood production—his organs would simply freeze and shut down one by one.

“Stay with me, Silas. Just a few more blocks. Come on, look at me,” Julian muttered.

Julian’s voice was trembling violently, fractured by a mixture of terror and severe cold. He was doing everything he could to keep Silas upright, his shoulder wedged firmly under Silas’s armpit, dragging his friend’s dead weight through the deepening slush. But Julian was completely out of his depth. He was a creature of academic halls and structured, gothic institutions—not the brutal, lawless depths of a corporate ice moon.

While Julian’s Siphon abilities remained perfectly intact, humming beneath his skin like a caged furnace, they were useless against the ambient temperature. He couldn’t manifest his energy to warm them without triggering every corporate sensor within a three-sector radius, an action that would bring a legion of Gliese enforcers down upon them in minutes.

Furthermore, Julian was suffering acutely from his own lack of preparation. His off-world tactical gear, designed for temperate climates and standard atmospheric conditions, offered virtually no protection against Cocytus Prime’s localized frost. Julian’s fingers were turning an ominous, bruised shade of purple inside his uninsulated gloves. They were so stiff that he could barely maintain his grip on a handheld map-pad. The device’s screen flickered wildly, its battery percentage skyrocketing downward by the second as the extreme cold sapped its lithium-ion cells.

A sudden, deafening howl of wind ripped through the massive structural ventilation shafts overhead. The vents, massive circular maws lined with rusted grating, groaned as they exhaled a blinding flurry of artificial ice. It wasn’t natural snow; it was sharp, granulated crystalline waste, a byproduct of the upper terraforming arrays. It hissed as it pelted their jackets, instantly layering their shoulders in white.

“The map is dead,” Julian cursed. His knuckles slammed against the useless piece of tech in frustration, the screen flashing one final, mocking error code before going completely dark. He shoved the dead weight into his coat pocket and looked around wildly, his chest heaving.

They were completely lost. The neon-lit, maze-like alleys of the Permafrost slums all looked identical. Shadowy, steam-choked channels of metal and ice snaked off in a dozen different directions, none of them offering a clear exit. Every surface was slick with frozen grease and black ice. Overhead, thick bundles of power cables and coolant pipes hung like frozen vines, dripping heavy condensation that froze before it hit the ground.

“Julian...” Silas gasped. His knees suddenly gave out, his boots sliding through the slush. He slid heavily down the icy corrugation of the wall, his head snapping back against the metal with a dull thud. His skin was a deathly, translucent pale, the dark circles under his eyes resembling deep bruises. His breathing had turned shallow, catching in his throat. “I can’t... there’s nothing left. My chest... it feels like ice.”

“Hey, no, no! Keep your eyes open!” Julian pleaded, dropping to his knees beside him. The freezing sludge soaked through Julian’s trousers instantly, making him hiss in pain, but he ignored it. He grabbed Silas by the collar of his coat, using all his remaining strength to haul the heavier boy back up, forcing Silas’s arm over his shoulder once more. “You didn’t bleed yourself dry just to freeze to death in a gutter, Silas. Stand up. Look at me!”

Silas’s eyes fluttered, the irises dull. He couldn’t even find the strength to speak, his head rolling loosely against Julian’s shoulder.

Before Julian could find the leverage to drag Silas back to his feet, a harsh, rhythmic mechanical clicking echoed from the thick fog at the end of the dead-end alley. It was a precise, metallic sound—the unmistakable cadence of multiple heavy limbs striking frozen deck plating.

Julian froze, his heart leaping into his throat.

Three shadowed silhouettes emerged from the swirling neon steam. They weren’t human, nor did they possess any human grace. They were automated corporate clean-up drones, low-tier security units manufactured by the Gliese Consortium to keep the lower service sectors clear of “organic debris.” To the Consortium, the homeless, the refugees, and the stranded off-worlders were nothing more than a statistical nuisance that clogged the drainage grates.

The drones advanced in a terrifyingly synchronized tripod gait. Their chassis were angular blocks of unpainted steel, caked in frost and rust, and their central optic sensors glowed a sterile, unblinking icy blue. Instead of hands, their metallic limbs ended in heavy, rotating pneumatic drills and hydraulic cutters—tools meant for clearing thick ice blockages from the ventilation shafts, but easily capable of crushing human bone.

Julian gritted his teeth, a desperate anger flaring through his exhaustion. He reached for his sidearm, but his frozen, purple fingers could barely feel the shape of the grip. He couldn’t pull the weapon from its holster.

Frustrated and terrified, Julian stepped squarely in front of the semi-conscious Silas, shielding him with his own body. He closed his eyes for a fraction of a second, reaching deep into his core to unlock his Siphon energy. A faint, volatile crimson hum began to crackle around his knuckles, static electricity snapping against the frost on his coat. He knew that using his power would alert the Consortium’s sector grid. He knew they would be hunted within minutes. But as the lead drone spun up its pneumatic drill with a deafening, metallic shriek, Julian realized they wouldn’t survive the next sixty seconds if he didn’t fight.

He prepared to launch a desperate, explosive wave of Siphon energy, fully aware it might be their final stand.

A sharp, high-pitched whine cut through the howling wind, completely drowning out the sound of the drone’s drill.

Thump.

A small, heavy metallic cylinder bounced out of the steam, skittering across the ice before striking the lead drone’s front leg. For a millisecond, nothing happened. Then, a blinding blue dome of localized electromagnetic energy erupted from the cylinder.

The EMP wave tore through the dead-end alley with a visible ripple. The lead drone’s blue optic sensor shattered outward in a cascade of sparks. The crimson energy around Julian’s knuckles was violently snuffed out, the magnetic field momentarily disrupting his own Siphon frequencies and sending a sharp ache through his forearms. The three corporate machines groaned, their internal gyroscopes failing instantly as their processing units fried. They collapsed into the slush, heavy steel chassis slamming into the ground with a resonant, metallic boom, their gears grinding to a final, smoking halt.

Julian stumbled backward, gasping, his hands still raised defensively.

From the thick curtain of neon-lit steam, a figure stepped forward. He moved with an easy, practiced grace that only came from decades of navigating slick ice and dangerous territory. He wore a heavy, multi-layered environmental suit made of thick, industrial-grade synth-leather and padded thermal insulation. The fabric was heavily patched with mismatched materials, caked in grease and a thick crust of frost. Slung casually over his right shoulder was a heavy-duty plasma torch, its fuel line snaking around his torso to a pressurized tank on his back.

The figure reached up with a thick, insulated glove, flipping a switch on the side of his helmet. The polarized blast visor slid back with a hiss of pneumatic pressure, revealing a sharp, cynical face. The man looked to be in his late thirties, his skin weathered by artificial atmosphere and severe frost, his dark eyes hardened by a lifetime of survival.

“You off-worlders really are a special kind of stupid,” the man said. His voice was raspy, a heavy smoker’s gravel that carried clearly over the wind. He walked up to the nearest disabled drone and casually kicked its chassis, checking to ensure it was completely dead. “Walking into a Gliese sweep zone without thermal lining or a sector pass? You’re basically freezing yourselves to death for them. Saves the Consortium the power bills on the incinerators.”

Julian kept his stance defensive, his breath hitching as he tried to shield Silas from view. “Who are you?”

“The guy who just saved you from becoming corporate landfill,” the smuggler replied, his eyes narrowing as they flicked from Julian’s purple, exposed fingers down to the boy slumped against the wall.

He didn’t look like a corporate enforcer—he lacked the polished, clinical insignia of the Gliese security forces. He looked like a scavenger, a rat living in the walls of the machine. The man stepped closer, ignoring Julian’s defensive posture, and peered intently at Silas. His eyes tracked the deathly pale complexion of Silas’s skin, noting the distinct, sunken hollows of his cheeks and the way his pulse fluttered visibly against his throat.

The smuggler’s expression shifted from mild amusement to sharp intrigue. He leaned down, reaching out with a gloved finger to trace the faint, silvery scar tissue and tracking marks running along Silas’s inner forearm—the telltale anatomical markers of a specialized laboratory subject.

“Well, well,” the man murmured, a slow, humorless smirk spreading across his face. “Look at those tracking marks. That’s an anti-Siphon blood-carrier. Or at least, what’s left of one. He’s running completely on empty, isn’t he?”

Julian flinched, surprised that a random undercity scavenger could recognize Silas’s condition so instantly. “Can you help him?” Julian demanded, his voice cracking with desperation, abandoning any attempt to look formidable. “We have credits. Off-world accounts. We just need medicine—whatever stimulates blood production. And gear. Please.”

The smuggler chuckled, a dry, rattling sound that turned into a brief coughing fit. He hooked his plasma torch back onto his chest harness and looked them both up and down, his gaze lingering on the residual static still tracing Julian’s sleeves.

“First rule of Cocytus Prime, kid: nothing here is free,” the man said, crossing his arms. “Your off-world credits aren’t worth the data they’re written on down here. The Consortium locked down external banking sectors three cycles ago. But that off-world tech you’re carrying? That kinetic sidearm on your hip, and whatever dampener tech you used to get past the orbital grid? That’s worth something to the right people. Real wealth down here is measured in scrap, juice, and survival.”

He walked closer, his heavy, spiked boots crunching firmly into the ice. He reached down and roughly tilted Silas’s head up by his chin. Silas let out a weak, guttural growl, his eyes half-opening, but he couldn’t even summon the strength to pull away.

“His core temp is dropping below critical,” the smuggler noted, his cynical tone returning. “I have a cache of high-iron cellular stabilizers back at my workshop. It’s military-grade contraband. It’ll force his marrow to aggressively kick-start blood production before his internal organs freeze solid. And I’ve got enough insulated scrap-lining to keep you from losing those pretty fingers to frostbite. But like I said, it’s going to cost you. Every piece of working tech in your pockets, and a down-payment on whatever salvage is left inside that ship you crashed.”

Julian looked down at Silas. Silas’s breathing was growing shallower by the second, a thin layer of frost already beginning to form on his eyelashes. There was no choice. There had never been a choice.

“Deal,” Julian said, his voice firm despite the shivering. “Take the tech. Just get him out of the cold.”

The smuggler’s smirk widened, revealing a gold-capped canine. He reached down, easily hoisting Silas’s dead weight over his insulated shoulder with a grunt of exertion.

“Name’s Darius,” the smuggler said, turning toward a dark, heavy subterranean hatch disguised perfectly against the rusted foundation of the corporate tower behind them. He struck the locking mechanism with the heel of his palm, and the heavy iron door slid open with a screech, releasing a sudden, thick gust of stale, chemically heated air. “Welcome to the Permafrost, boys. Try not to die on my floor. It’s a bitch to clean.”
