The rain on Pelagia-4 did not fall; it drifted in greasy, sulfuric sheets, clinging to the rusted iron of Outpost Rust-Bucket like a second skin.

Cole Miller hauled his boots out of the yellow sea-foam, his shoulders aching under the dead weight of sixty kilograms of waterlogged canvas and brass. He had been down for six hours at the edge of the shallow sumps, his hands frozen into stiff, salt-bitten claws inside his heavy canvas gloves. Every breath in his throat tasted of copper filings and stale, recirculated nitrogen. On his back, the heavy copper-mesh filter of his regulator—a gift from his late father, Arthur—wheezed like a dying animal, struggling to scrub the ambient radiation from the brackish water he had spent the day crawling through.

Over his right shoulder, Cole carried a bulging burlap sack. Inside, the jagged edges of raw copper piping clattered with a dull, heavy metallic ring. It was a pathetic haul for six hours of blind crawling in zero-visibility mud, but in the slums of Rust-Bucket, it was the difference between a clean cup of water and a slow, agonizing death by heavy metal poisoning.

He walked down the creaking, lashed-together gangway of the wet-docks. The floating slums stretched out around him—a chaotic labyrinth of rusted shipping containers, rotting fiberglass hulls, and patched neoprene tents, all riding the slow, greasy swells of a world that was ninety-nine percent water. Above, the sky was a bruised, industrial purple, illuminated only by the distant, clean white glow of the Aegis Oceanic sky-domes. Those sterile glass bubbles sat miles away on the horizon, anchored to the seabed by massive tension cables, completely insulated from the acid rain and the radioactive runoff that poisoned the surface barges.

Cole ignored the stares of the other divers—gaunt, hollow-eyed men who sat on the edges of their barges, nursing cups of bitter kelp tea and shivering under tattered thermal blankets. He kept his eyes down, his gaze fixed on the muddy wooden planks beneath his steel-toed boots. He had to get to the Scrap-Yard Commons before the evening shift change, or the collectors would dock his pay for 'late delivery.'

"Cole!"

A raspy, wet cough cut through the steady patter of the rain. Cole stopped, his heart tightening. He turned his head toward a small, patched neoprene tent pitched on the deck of a neighboring iron barge.

Uncle 'Barnacle' Ben was standing in the doorway, his stocky, sixty-eight-year-old frame hunched against the wind. The old man’s bald head was covered in deep grease scars, and his thick, coke-bottle glasses were smeared with salt-spray. He was wearing his heavy, oil-stained mechanic’s apron, his right hand buried in a pocket, while his left hand gripped a worn steel wrench like a protective talisman.

"You're late back, boy," Ben said, his voice a gravelly rumble. "The collectors are in a foul mood today. Overseer Vance is down at the scales himself. He brought the shock-baton boys from the administrative tower."

Cole wiped a smear of yellow grease from his visor. "How's Clara?" he asked, his voice low and gruff.

Ben's face fell, the deep wrinkles around his eyes tightening. He looked back into the dark interior of the tent. "She's wheezing worse than yesterday, Cole. The filtration unit on her bed is rattling. The copper pipes are completely scaled up with heavy metal crust. I tried to clean the injectors with wire, but... she needs clean water, son. Real, non-irradiated water. Not the gray bilge we've been boiling."

Cole's grip on the sack of copper piping tightened until his knuckles turned white inside his canvas gloves. "I've got sixty kilograms here," he said, gesturing to the sack. "And three water filtration tablets left in my suit pouch. I'll get her what she needs, Ben. I swear it."

"Just... watch yourself around Vance," Ben warned, lowering his voice as a pair of corporate guards in sleek, white-and-chrome armor patrolled the upper gangway. "He's looking for a reason to clear the outer barges. The board off-world is screaming about production drops."

Cole nodded once, a sharp, decisive jerk of his chin. He turned and continued down the gangway, the heavy boots of his dive suit clumping against the wood.

The Scrap-Yard Commons was a massive, open-air barge anchored in the center of the outpost. It was dominated by a giant, creaking iron crane that Aegis Oceanic used to lift the daily salvage hauls into cargo containers for transport to the deep-water domes. The air here was thick with the smell of wet rust, ozone, and burning diesel from the crane's ancient engine.

A long line of independent divers stood in the rain, their sacks of scrap resting at their feet. At the front of the line, sitting behind a heavy steel counter protected by a corrugated plastic awning, were the corporate Scrap-Tax Collectors. Beside them stood Overseer Vance.

Vance was a balding, overweight man in his late forties, but there was nothing soft about his eyes. They were cold, calculating, and completely devoid of empathy. He wore a pristine, high-collared white corporate uniform that seemed like an insult to the dirt and rust of the slums around him. In his hand, he casually turned a gold-plated electronic datapad, his fingers tapping the screen with a rhythmic, irritating click.

When Cole finally reached the counter, he hoisted his sack and dumped the raw copper piping onto the heavy iron scale. The metal clattered loudly, several pipes rolling against the steel guardrails.

"Cole Miller," the lead collector mumbled, not even looking up as he adjusted the scale's digital weight calibration. "Sixty-two kilograms. Raw copper piping. Industrial grade."

Cole leaned against the counter, his breathing heavy. "That's my quota for the week, plus twenty kilograms of excess. I need my water tokens. And my sister's medicine allocation."

The collector stopped. He looked up, a cold, indifferent smirk on his face. He tapped a key on his terminal, then looked at Overseer Vance, who stepped forward, his boots clicking on the metal deck.

"Not so fast, Miller," Vance said, his voice smooth and dripping with bureaucratic malice. "The guidelines changed this morning. Direct order from the regional operations board in Pelagia-Prime. All low-grade industrial plumbing is subject to a forty percent 'slag deduction' due to high calcification and environmental oxidation."

Cole felt a cold spike of panic in his chest. "What?" he rasped, stepping closer to the counter. "You can't do that. This copper is clean. I scraped the scale off myself. My father's contract—"

"Your father's contract is thirty years old, Miller," Vance interrupted, his eyes narrowing. "And your father is dead. The current market demands high-purity, military-grade copper. This garbage you brought in is barely fit for ballast. After the slag deduction, you're credited with thirty-seven kilograms. Which leaves you exactly thirteen kilograms short of your weekly quota."

"Thirteen kilograms short?" Cole's voice rose, attracting the attention of the surrounding guards. "I spent six hours in the sumps for this! If I don't get those water tokens, my sister's filtration bed stops running. She can't breathe the air out here without it!"

"Then you should have worked harder," Vance said coldly. He tapped his datapad. "Furthermore, there's the matter of Uncle Ben's workshop. The administrative office has levied a retroactive environmental maintenance tax on all independent mechanical bays. Two hundred water tokens. Since you are registered as his primary financial guarantor, that debt has been added to your account."

"Two hundred tokens?" Cole slammed his leather-gloved fist onto the steel counter. "That's extortion! Ben's workshop hasn't had electricity from the main grid in five years! What environmental maintenance are we paying for?"

Two corporate guards instantly stepped forward, their hands resting on the handles of their high-voltage shock-batons. The blue indicator lights on the weapons pulsed in the dim rain.

Cole froze. He looked at the guards, then at Vance's smug, arrogant face. He knew what would happen if he fought. They would throw him into the wet-dock holding cells, and Clara would be dead before the week was out. He had to negotiate. He had to use whatever leverage he had left.

Reaching into the utility pouch on his dive suit's thigh, Cole pulled out three small, circular blue tablets. They were Water Filtration Tablets—the primary currency of the slums, highly concentrated chemical purifiers that could turn five liters of toxic surface water into clean, drinkable liquid. They were all he had left from his last three months of savings.

He placed them gently on the steel counter, sliding them toward Vance with his right hand.

"Three tablets," Cole whispered, his voice shaking with suppressed rage. "That's fifteen liters of pure water. Take them. Just give me the medicine allocation for Clara. And give Ben another week on the debt."

Vance looked down at the tablets. He reached out with two fingers, sliding them into his palm. He pocketed them in his clean white uniform with a smooth, practiced motion.

"I appreciate the donation to the administrative safety fund, Miller," Vance said, his voice dropping to a cold, mocking whisper. "But corporate policy is absolute. I cannot credit personal property toward official metal quotas or tax debts. You have forty-eight hours to deliver the remaining thirteen kilograms of high-grade copper and the two hundred tokens for Ben's workshop. If you fail, the Miller float-tent will be disconnected from the communal water line, and your sister will be evicted to the outer toxic barges."

"Vance, please," Cole pleaded, his pride completely shattered. He reached into his pocket and pulled out a faded, water-damaged piece of physical paper—his father Arthur's original employment contract, which guaranteed perpetual mooring rights for the Miller family barge. "Look at the contract. My father gave thirty years of his life to Aegis. He died down there! You can't just throw us out!"

The collector looked at the paper, then at Vance. Vance merely nodded, a gesture of supreme indifference.

The collector snatched the paper from Cole's hand. With a quick, brutal twist of his wrists, he tore the contract in half, then shredded it into tiny pieces, letting the wet scraps flutter down into the yellow, oily water of the harbor below.

"Forty-eight hours, Miller," Vance said, turning his back on Cole. "Make it count."

Cole stood frozen at the counter, his empty hands trembling. The weight of his brass helmet felt like a mountain pressing down on his neck. He wanted to leap over the counter and tear Vance's throat out, but the cold hum of the guards' shock-batons kept him pinned to the deck.

He slowly gathered his empty burlap sack, turned, and walked away from the scales. He had lost his entire daily salvage haul. He had lost his remaining water tablets. He had zero profit, a ticking clock, and forty-eight hours to save his sister's life.

He walked back to the Miller Float-Tent in a daze, his heavy boots dragging against the wet wooden planks of the gangway. Every step felt like he was wading through thick, high-pressure mud. The rain was getting heavier, the yellow drops stinging his face where his visor was cracked.

He pushed aside the heavy, grease-stained neoprene flap of the tent and stepped inside.

The interior of the tent was small, cramped, and smelled of wet canvas, vinegar, and the sharp, metallic tang of copper. In the corner, sitting on a low iron cot, was sixteen-year-old Clara.

She was pale and thin, her bright, intelligent hazel eyes looking massive in her gaunt face. Her short-cropped brown hair was damp with sweat, and she wore a pair of oversized, grease-stained mechanic overalls that had belonged to their father. She was hooked up to a wheezing, copper-piped oxygen concentrator that rattled with every breath she took. The machine's plastic mask was strapped to her face, its rubber tubing wheezing as it struggled to pump filtered air into her failing lungs.

As Cole entered, she looked up, her eyes crinkling into a tired, sarcastic smile. She pulled the mask down to her chin, instantly triggering a dry, hacking cough that shook her fragile frame.

"Hey, big brother," she wheezed, her voice a soft, raspy whisper. "You look like you just got dragged through a ship's propeller. Did the sea try to eat you again?"

Cole forced a tight, reassuring smile onto his face. He walked over to her bed, dropping his heavy canvas sack on the floor. He sat on the edge of the iron cot, the metal groaning under the weight of his dive suit.

"Just the usual currents, Clara," he said, his voice softening as he reached out to brush a damp strand of hair from her forehead. His hand was cold and rough, but she leaned into his touch anyway. "How are you feeling?"

"Oh, fantastic," she said, her sarcastic humor masking the genuine fear in her eyes. "I coughed up three silver flecks this morning. I think I'm turning into a high-grade alloy. Uncle Ben says if I keep this up, he can melt me down to pay off his taxes."

She laughed, but the laugh instantly turned into a violent, hacking fit. She clutched her chest, her face turning a terrifying shade of blue-gray as she struggled to draw breath. Cole quickly reached for the oxygen mask, pressing it back over her nose and mouth.

"Breathe, Clara. Slow, deep breaths," he commanded, utilizing the calm, rhythmic tone his father had taught him for deep-sea emergencies. "Double-breath. Inhale... hold... exhale half. Come on, do it with me."

She followed his rhythm, her chest rising and falling in slow, painful jerks. Slowly, the blue-gray tint faded from her cheeks, and her breathing settled into a shallow, wheezing rattle. She closed her eyes, her hand gripping Cole's heavy sleeve with surprising strength.

Cole watched her, his heart breaking. The heavy metal dust in the air and water—the 'Rust-Lung'—was slowly crystallizing her lung tissue, turning her organic lungs into hard, unyielding metal. Without the Blue-Gel suppressants that only Aegis possessed, her lungs would completely calcify within a year. And now, Vance was threatening to cut off their water and throw them out into the toxic storms.

"Cole."

He turned. Uncle Ben had slipped into the tent, his heavy boots dripping water onto the floorboards. The old man looked older than his sixty-eight years, his shoulders hunched under the weight of his own worries.

"I heard what happened at the scales," Ben said, his voice barely a whisper over the rattling of the oxygen concentrator. "That bastard Vance. He's squeezing us dry, Cole. He knows we can't pay that tax. He wants my workshop. He wants to sell the drilling equipment to the corporate contractors."

"I won't let him take it, Ben," Cole said, standing up. "I'll go back down. I'll find the copper. I'll dive the deep sumps near the outer barrier. There's got to be some scrap left from the old cargo barges."

"No," Ben said, shaking his head. "The outer barrier is completely stripped, Cole. You know that. Every independent diver in the sector has been crawling over those wrecks for ten years. There's nothing left but rusted iron and lead slag. You won't find thirteen kilograms of high-grade copper down there in forty-eight hours, let alone enough to pay off my tax."

Cole looked down at his boots. "Then what do I do, Ben? I can't let them evict her. She won't survive a single night in the outer barges. The acid rain will eat through her tent in hours."

Ben stepped closer, his coke-bottle glasses catching the dim yellow light of the tent's single oil lamp. He looked back toward the tent flap, making sure no one was listening, then leaned in close to Cole.

"There's a rumor, Cole," Ben whispered, his voice trembling with a mixture of excitement and absolute terror. "A rumor from the old divers. The ones who worked the deep lines before the flooding got bad."

Cole looked at him, his interest piqued. "What kind of rumor?"

"A pre-war wreck," Ben said, his eyes wide. "A massive, Sledge-class heavy mining vessel. It sank fifty years ago during the first planetary flood. They say it was carrying a full cargo of heavy-isotope lead sheets and high-purity copper conduits before the navigational systems failed."

Cole's eyes narrowed. "If it's a pre-war wreck, why hasn't Aegis salvaged it? They have the deep-sea subs. They have the coordinates of every ship that sank during the flood."

"Because of where it sits, Cole," Ben said, his voice dropping even lower. "It didn't sink in the open ocean. It drifted into the outer silt-flats. Right on the edge of the restricted perimeter of Sector 90."

Cole felt a cold sweat break out on his neck. "Sector 90? That's the sunken nuclear reactor site. The water down there is highly radioactive. Aegis has a complete naval blockade around the perimeter. They have automated security drones patrolling the deep channels. Anyone who goes within five hundred meters of that sector is shot on sight."

"I know," Ben said, his grip on Cole's arm tightening. "It's suicide for a standard diver. But you're a Master Diver, Cole. Your father taught you how to read the deep-sea sonar, how to navigate the acoustic shadows of the basalt caves. You have the lead-lined canvas suit. You have the heavy regulator. You can survive the depth."

Cole looked back at Clara. She had fallen into a light, fitful sleep, her chest rising and falling to the rhythmic wheezing of the machine. Her face was so pale, so fragile. She looked like a ghost already.

He knew the risks. Sector 90 was a graveyard of twisted metal and hot, bubbling radioactive silt. The hydrostatic pressure at three hundred meters was thirty atmospheres—enough to crush a standard canvas suit like an empty soda can. A single tear in his neoprene seals, a single failure of his copper regulator, and he would drown in pitch-black, radioactive water.

But playing by corporate rules was a losing game. Vance and Aegis had designed the system to keep them in a perpetual cycle of debt and dependency, squeezing them until they had nothing left to give, and then discarding them like scrap metal.

If he wanted to save Clara, if he wanted to secure a future for his sister, he had to stop diving for scraps. He had to go into the dark.

Cole turned back to Ben, his jaw set, his eyes cold and filled with an iron-willed determination.

"Where are the coordinates, Ben?" Cole asked, his voice steady.

Ben reached into his pocket and pulled out a small, heavy brass pocket watch. He pressed a button on the side, and the back of the watch popped open, revealing a tiny, hand-scratched map etched into the inner brass casing.

"If you're going into the edge of Sector 90, Cole," Ben whispered, his voice barely carrying over the rattling of the oxygen concentrator, "you aren't just diving for scrap anymore. You're diving into a graveyard. And the things down there don't like to be disturbed."
