The terminal rattle of the Hebe-V1 was the only clock that mattered in the damp dark of Level 0. It was a rhythmic, metal-on-metal wheeze, like a dying lung scraping against a rusted rib cage. Every time the machine clicked, the amber light on its cracked casing flickered, casting long, distorted shadows of copper tubing across the damp concrete walls of the basement sanctuary.

Danny Vance sat on the edge of a collapsed turbine casing, his head buried in his hands. His palms were wrapped in thick, oil-stained bandages, but the grease had long since soaked through, turning the gray cloth into a slick, black paste. He didn't dare unwrap them here. The air in the Rust-Quarter was too thick with sulfur and acidic condensation; if the raw, skinless flesh of his hands was exposed to the draft for more than a few minutes, the chemical sting would drag him to his knees.

"Danny?"

The voice was barely a whisper, thin and dry as parchment.

Danny looked up, forcing his shoulders to straighten, forcing a smile onto his face that felt like splitting dry leather. Clara was lying on a cot of industrial wool, her thin frame nearly swallowed by the oversized corporate jumpsuit he had salvaged for her. She was only fourteen, but the synthetic nerve decay had already stolen the color from her cheeks, leaving her skin a translucent, ghostly white. Beneath the surface of her neck, faint, glowing blue veins pulsed with a cold, erratic light—the unmistakable signature of the Delta-Strain mutation.

"I'm here, Clary," Danny said, his voice quiet, filtered through the worn cloth of his face mask. He stood up, his knees popping with a dry, mechanical sound. He walked to her side, careful not to let his boots click too loudly on the floor grates.

"It's cold," she murmured, her glassy gray eyes tracking his movement. "The heater... did it stop again?"

Danny glanced at the corner of the basement. The small, jury-rigged generator he had built from a discarded corporate fuel cell was silent, its copper coils cold. "Just a loose wire, Clary. I'll fix it. I just need to get some more grease for the generator. And for you."

He reached out, his bandaged hand hovering over her forehead. He wanted to brush her hair back, to offer some small comfort of human touch, but he stopped. The raw friction burns beneath his bandages were weeping, and the risk of infection was too high. He drew his hand back, clenching his fists until the raw dermis of his palms split, a slow, hot trickle of blood soaking into the grease-stained wraps.

"The blue gel," Clara whispered, her eyes closing. "The blue gel makes the humming stop."

She was talking about her nerves. When the decay flared, her entire nervous system vibrated with a high-frequency hum, a constant, agonizing static that felt like liquid fire sliding through her veins. The only thing that slowed the vibration was the Low-Grade Bio-Synthetic Lubricant—a thick, chemically active blue grease smuggled from the corporate waste dumps of the upper sectors. Applied directly to her spine, it numbed the nerves, buying her a few hours of painless sleep.

But the canister on the shelf was empty. Danny had scraped the last blue smear from its bottom yesterday morning.

"I'm going to get it, Clary. I promise," Danny said, his voice hardening. "Just stay still. Don't move. The more you move, the faster the hum builds."

He turned away before she could see the desperation in his eyes. He walked to the corner of the basement, where his gear lay scattered on a grease-slicked workbench. He picked up his Slick-Shoes—a pair of heavy, reinforced scavenger boots fitted with low-friction chromium plates on the soles. The plates were deeply grooved and pitted from his last run, the edges sharp enough to cut. They needed to be recast, but there was no time.

Danny sat down, pulling the boots onto his feet and tightening the heavy leather straps until his ankles were locked rigid. He reached for a small, pressurized aerosol can—the last of his Emergency Cohesion Pack—and shook it. The liquid inside rattled hollowly. There was barely enough for a single spray. He set it aside, slipping it into the transparent pocket of his vest, right next to Clara's hand-drawn star map. The small piece of synthetic parchment, covered in charcoal drawings of a clean, unpolluted sky, was his only lucky charm.

He stood up, stamping his heels together. *Clack.* The chromium plates on his soles engaged, aligning perfectly with the magnetic tracks built into the heels.

"Street-Sliding," he muttered to himself, taking a deep, measured breath. He closed his eyes, focusing on the unique, genetic anomaly that lay dormant in his blood. The Delta-Strain. In Clara, it was a degenerative curse that dissolved her nerves. In Danny, it was a physical aberration that allowed him to manipulate his body's relationship with the physical laws of the universe.

He focused on his soles, letting his mind reach down to the cellular level of his skin. He felt the microscopic rough edges of his cells, the physical hooks that gripped the world and created traction. With a silent, practiced pull of his will, he smoothed them out. He eliminated the friction coefficient of his skin, dropping it to near-zero.

Instantly, the world lost its anchor.

Danny didn't step forward; he fell horizontally. The slight slope of the basement floor was enough to send him sliding, his Slick-Shoes skimming over the damp concrete without a sound. It was a dizzying, weightless sensation, like falling through empty air, but his body was moving parallel to the ground. He caught the edge of the door frame with his bandaged hand, his fingers sliding effortlessly off the rusted iron before he managed to grip it by sheer muscle pressure.

He opened the heavy steel hatch, stepping out into the suffocating humidity of the Rust-Quarter.

Level 0 was a vertical labyrinth of rusted iron, toxic steam, and neon light. Massive, twenty-foot-wide pipes ran along the ceilings of the alleys, carrying the boiling chemical waste of the upper corporate sectors to the outer wasteland. The air was a thick, yellow fog that tasted of sulfur and wet copper. High above, the massive exhaust vents of the Spire breathed down a constant, hot sigh, keeping the slums in a perpetual state of damp, greasy heat.

Danny pushed off from the door frame, initiating his slide. He moved down the narrow, rain-slicked alley, his speed building instantly. Thirty miles per hour. Forty. The wind ripped at his face mask, and the air resistance immediately began to bite.

At this speed, even the air itself had friction. Danny could feel the heat building along his face, his neck, his bare forearms. The air molecules dragged against his skin like microscopic sandpaper, peeling away the outer layers of his epidermis. It was a slow, agonizing sloughing. He could feel his skin cells tearing loose, dissolving into a fine, bloody mist that trailed behind him in the yellow fog. He kept his head down, his teeth clenched, his eyes locked on the wet, neon-lit metal plates of the street.

He didn't dare drop his friction to absolute zero. If he did, his molecular cohesion would fail, and his body would dissolve into a formless, liquid cloud of kinetic energy. He had to maintain a delicate balance—just enough friction to keep his body together, but low enough to maintain his sliding velocity.

He reached the border of Sector 4, the massive, chaotic dumping ground of the slums. The Sector 4 Scrap Yards were a mountain of corporate waste—shattered glass, rusted steel girders, and leaking chemical tanks that had been discarded from the upper levels. It was a lawless zone, patrolled by rival scavenger gangs and automated corporate security drones that shot on sight to protect the high-value scrap.

Danny slowed his slide, grinding his heels against a patch of wet gravel to restore his friction. The sudden traction sent a violent shockwave up his legs, his knees buckling as his joints absorbed the kinetic impact. He stumbled, catching himself against a rusted iron pillar, his breath coming in ragged, painful gasps.

He looked down at his boots. The chromium plates were hot, smoking slightly in the damp air. He needed to find the waste runoff pipe quickly.

He slipped into the shadows of the scrap piles, his boots crunching softly on the debris. He navigated the narrow gaps between the towering mountains of metal, his eyes scanning the rusted structures. After ten minutes of searching, he heard it—the steady, heavy dripping of thick liquid. He rounded a corner and found the runoff pipe, a massive, cracked conduit that jutted out from the concrete foundation of the upper sector.

Leaking from the crack was a steady stream of thick, iridescent blue gel. The Low-Grade Bio-Synthetic Lubricant.

Danny felt a surge of relief that nearly brought him to tears. He pulled a rusted metal canister from his satchel, holding it beneath the drip. The blue gel fell slowly, plopping into the canister with a heavy, chemical scent that smelled of ammonia and synthetic wax. It was contaminated, filled with industrial impurities, but it was enough. It would keep Clara's nerves quiet for another week.

"Well, look what we have here."

The voice was low, heavy, and dripping with a cruel, territorial amusement.

Danny froze. He slowly turned his head, his hand still holding the canister beneath the dripping pipe.

Standing at the entrance of the scrap clearing was a massive, broad-shouldered youth. His skin was rough and leathery, covered in dark, sticky patches of grease. His hands were oversized, his palms glistening with a thick, viscous secretion that left sticky, gray marks on the rusted iron he leaned against.

It was Grip Gary, the dominant scavenger of Sector 4.

"You're in the wrong yard, Slick," Gary said, stepping forward. His heavy boots crushed the metal scrap beneath his feet with a deliberate, intimidating crunch. "That runoff belongs to the Rust-Claws. And everything that comes out of it has a tax."

Danny didn't speak. He slowly drew the canister away from the pipe, sealing the lid with a tight, metal click. He slipped it into his satchel, his eyes tracking Gary's movement, calculating his exit vectors.

"I don't want any trouble, Gary," Danny said, his voice muffled by his respirator. "My sister needs this. I'm leaving."

"You're leaving when I say you can leave," Gary barked, his face darkening. He lunged forward with a speed that belied his massive size. His hands, coated in the hyper-friction secretion, shot toward Danny's shoulders.

Danny tried to slide back, but his boots were still on the rough, dry gravel. Before he could build momentum, Gary's massive palms slammed onto his shoulders.

Instantly, the hyper-friction took hold. Gary's secretion acted like a chemical weld, locking Danny's shoulders in a vice-like grip. The friction coefficient between Gary's palms and Danny's vest spiked to near-infinity. Danny was completely pinned. He couldn't slide; he couldn't twist. Every muscle in his body strained against the grip, but it was like trying to pull himself out of solid concrete.

"Gotcha, you slippery little rat," Gary sneered, his face inches from Danny's mask. "Let's see you slide out of this."

Gary raised his knee, intending to deliver a crushing blow to Danny's ribs.

Danny had only one option. It was a terrifying, high-risk maneuver. He had to drop the friction coefficient of his entire upper body—including his skin—to absolute zero.

He closed his eyes, his mind screaming as he pulled the physical anchor from his flesh.

*Zero.*

The effect was instantaneous and horrific.

Gary's hands, which had been locked onto Danny's shoulders with absolute traction, suddenly found nothing to grip. The friction between their bodies vanished. Gary's massive weight carried him forward, his hands slipping off Danny's shoulders as if they were coated in frictionless ice.

But the sudden, violent release of traction came at a devastating cost. The shear-stress of Gary's rough, leathery palms sliding off Danny's shoulders tore away the outer layers of Danny's skin. A large, jagged patch of flesh along Danny's collarbone and shoulder was ripped clean off, leaving the raw, pink dermis exposed to the toxic air.

Danny screamed, a high, strangled sound of pure agony. The chemical-laden air of the scrap yard hit the raw flesh, burning like liquid acid. Blood erupted from the wound, but because his body was in a zero-friction state, the blood didn't run down his chest; it sprayed outward in a fine, misted halo, hovering in the air around him.

Gary stumbled forward, his own momentum throwing him off balance. He crashed heavily into the rusted iron pipe, his hyper-friction palms sticking to the metal and tearing his own skin as he tried to pull free.

*Beep. Beep. Beep.*

A sharp, high-pitched mechanical tone cut through the steam.

Danny's eyes snapped open, his vision blurring from the pain. High above the scrap piles, a pair of hovering corporate security drones dropped from the yellow clouds. Their sleek, white casings were a stark, clean contrast to the rusted filth of Level 0. Their red optical sensors spun, locking onto the sudden kinetic spike and the blood mist hovering in the air.

"Warning," a synthetic, metallic voice chimed from the drones. "Unregistered mutant activity detected. Identify yourself and submit to pacification."

"Drones!" Gary yelled, his territorial pride instantly replaced by panic. He managed to rip his hands free from the pipe, scrambling into the deep shadows of the scrap piles.

Danny didn't wait. He dropped his lower-body friction, his Slick-Shoes engaging the wet metal plates of the scrap yard floor. He initiated a slide, his velocity building instantly as he fled the clearing.

"Target non-compliant," the drone voice chimed. "Initiating lethal sweep."

The twin barrels of the drones' kinetic rifles spun, and a hail of high-velocity rounds chewed into the rusted iron behind Danny.

Danny was moving at fifty miles per hour, his body low, his hands tucked close to his chest. He was sliding blind through the maze of scrap piles, his respirator HUD flashing red with thermal warnings. The air friction was peeling the skin from his face, the raw flesh beneath his mask weeping and burning.

He had no brakes. In a frictionless state, he couldn't stop, and he couldn't change direction without colliding with a solid surface.

Ahead of him, a massive pile of discarded steel girders began to collapse, triggered by the drone's gunfire. A multi-ton iron plate fell directly into his path, blocking the alleyway.

"No, no, no!" Danny gasped, his lungs burning from the sulfurous air.

He couldn't stop. If he crashed into the plate at fifty miles per hour, his bones would shatter. He had to redirect his momentum.

He looked to his right. A curved, rusted boiler tank lay half-buried in the scrap.

Danny leaned his body weight into the turn, his Slick-Shoes skimming along the wet concrete. He aimed his slide directly toward the curved side of the boiler. Just before impact, he restored a fraction of friction to his left sole, using the *Surface-Adhesion* technique to lock his boot to the curved metal for a split second.

*Sparks.*

The sudden traction sent a violent shudder through his leg, but the centrifugal force carried him up and around the curve of the boiler, redirecting his momentum in a perfect, smooth arc. He bypassed the falling iron plate, sliding out of the collapsing alleyway and back into the open, wet streets of the Rust-Quarter.

The drones pursued, their thrusters whining as they navigated the narrow gaps. They opened fire again, the kinetic rounds sparking violently against the metal street plates around his boots.

Danny was pushing his speed to the absolute limit. Sixty miles per hour. The air was a wall of solid heat, melting the outer layers of his suit, the smell of burning rubber and singed hair filling his respirator. His skin was sloughing off in large sheets along his legs and torso, the raw, bleeding flesh exposed to the intense heat of the air resistance.

He could feel his consciousness slipping, his mind drifting toward the cold, quiet dark of molecular dissolution. He wanted to stop. He wanted to let the friction take him, to let his body dissolve into the wind.

But then he thought of Clara. He thought of her pale face, her glowing blue veins, and the terminal rattle of the Hebe-V1. He thought of his promise to keep her breathing.

He clutched the canister of blue gel in his satchel, his raw fingers locking onto the cold metal.

*Just a little further,* he told himself. *Just make it to the drainage pipe.*

He saw the entrance of the drainage pipe ahead—a dark, narrow opening beneath a massive steam vent. It was his only escape route. The drones were too large to follow him inside.

He aligned his body with the opening, dropping his friction to its lowest safe limit to build a final burst of speed.

But as he reached the threshold of the pipe, his boots hit an unexpected obstacle.

A massive, highly rusted steel plate, jagged and pitted from decades of acidic rain, lay half-buried in the mud directly in front of the opening. It was completely dry, the rough rust acting like a high-friction trap.

Danny had no time to redirect. He had no time to lift his boots.

His Slick-Shoes hit the dry, rusted plate at sixty miles per hour.

*SCREEECH!*

The metal-on-metal contact was violent and catastrophic. The chromium plates of his soles ground against the rough rust, the friction coefficient spiking instantly.

A massive, blinding shower of bright orange sparks erupted from beneath his boots, a brilliant firework of heat and light that illuminated the dark, toxic alleyway.

The heat was instantaneous and intense. The sparks caught the leaking, volatile blue grease that had dripped from his satchel onto his ankles. A sheet of white-hot pain bloomed across his raw, exposed flesh, the flames licking at the raw dermis of his legs, threatening to set his entire body on fire.

Danny gasped, his eyes widening in pure terror as the fire began to climb his legs, his body still hurtling forward into the dark opening of the pipe.
