The sulfurous muck of Sector 12 clung to Marcus’s boots like cold grease, but he couldn't feel it. Under the artificial 2G gravity of the Deep Shafts, his paralyzed lower limbs were nothing but a heavy, unresponsive anchor dragging through the dark. He sat propped against a rusted iron cargo crate, his head resting against the cold, damp bedrock of the cavern wall. A steady, thin trickle of blood had dried into a dark crust beneath his left nostril—the bitter, metallic calling card of the Kinetic Feedback Leak that was slowly turning his bones to glass.

Beside him, Jax stood in the dim green glow of the bioluminescent phosphor fungi, his massive, bald head glistening with sweat. The burly borer was staring down at the deep, wide ruts carved into the wet shale. They weren't the erratic, jagged tracks of mining loaders; they were smooth, perfectly parallel grooves left by stabilized gravity thrusters attempting to arrest a terminal, high-altitude descent.

"A military ship," Jax repeated, his deep voice muffled by the heavy, moisture-laden air. He looked back at Marcus, his jaw set in a hard line. "If the reactor is intact, Marcus... that means there's a pristine, military-grade G-Core sitting in the wreckage. A core that isn't cracked. A core that won't kill you every time you use it."

Marcus closed his eyes, his mind instantly analyzing the tactical reality. His own salvaged G-Core—the cracked, unstable engine currently mounted to his manual harness—was humming with a low, discordant vibration that rattled against his ribs. The diagnostic screen on his wrist-mount flickered, showing a battery charge of seventy percent. Using it to slow their descent down the vertical scaffolding had drained a massive portion of his reserves. If they had to fight their way through Sector 12 to reach that wreck, every micro-second of gravity manipulation would push him closer to the calcium calcification threshold Dr. Evelyn had warned him about. His left knee was already fifty percent fused, a rigid rod of calcified bone that made his leg stick out like a broken timber.

"We don't know who else saw the crash," Marcus rasped, his voice dry and gravelly from the sulfur fumes. He wiped the dried blood from his lip with the back of his calloused hand. "A military-grade signature doesn't go unnoticed down here, Jax. The scavengers will be crawling over those tracks like cave-rats on a carcass. Hoist me up. We need to move before the trail goes cold."

Jax didn't hesitate. He knelt in the muck, his heavy, black-market hydraulic leg braces hissing quietly as the steam pistons along his thighs compressed. With a grunt of practiced ease, he pulled Marcus onto his broad back, securing the reinforced leather and iron harness across his chest. The added weight of Marcus's body and the manual harness made Jax’s braces groan, a low, metallic protest that echoed through the narrow cavern.

"I've got you, pilot," Jax muttered, his massive hands locking onto the rungs of his industrial borer drill as he stood. "Just keep your eyes on the dark."

They followed the deep thruster ruts away from the shattered elevator shaft, heading deeper into the unmapped vertical labyrinth of Sector 12. The Deep Shafts were a tomb of forgotten industry. Massive, rusted steam pipes as thick as ore haulers hung from the ceiling like frozen serpents, dripping warm, oily condensation onto the wet rock below. The air was thick, hot, and smelled of ancient, compressed earth. Every breath felt like inhaling wet velvet.

Marcus kept his Structural Weight Awareness expanded, his mind mapping the physical stress points of the cavern. He could feel the immense weight of the bedrock pressing down from miles above, the tension in the half-collapsed iron scaffolding that clung to the vertical walls, and the slow, heavy movement of the Silt Union miners working in the distant, lower pits. But as they entered a narrow, vaulted bypass tunnel, his mental grid suddenly flared with a series of sharp, rhythmic vibrations.

Footsteps. Dozens of them. Moving fast, and they were closing in from the lateral ventilation shafts.

"Jax, stop," Marcus whispered, his hand clamping onto Jax’s shoulder. "We've got company. Heavy footfalls. Behind the rusted support pillars."

Jax instantly froze, his hand dropping to the trigger of his Titan-Borer Drill. The diamond-tipped teeth of the drill remained still, but the steam valves along its chassis began to hiss with a low, threatening hiss.

From the shadows of the twisted iron scaffolding, a dozen figures detached themselves, stepping into the dim green light. They were clad in bulky, overlapping plates of scrap steel salvaged from old ore haulers, their faces hidden behind crude, grease-stained welding masks. In their hands, they held heavy, custom-built kinetic cleavers—brutal blades designed to shatter rock and bone alike under the Silt's crushing gravity. This was the outlaw vanguard of the Deep Shaft Scavengers.

At the center of the group stood Garrick, the brutal young gang lord of Sector 7. He was a massive, scarred brawler, his chest covered in a heavy coat of overlapping, rusted metal plates. He held a massive, rusted iron cleaver loosely in his right hand, the blade caked with dried mud and old grease. He looked at Jax, then let out a cruel, wet sneer that revealed several gold-capped teeth.

"Well, well," Garrick rumbled, his voice echoing off the damp stone walls. "If it isn't the Silt Union’s big borer. I heard you were carrying a cripple on your back, Jax, but I didn't think you'd be stupid enough to bring him into my territory without my leave."

Jax took a slow, heavy step forward, his hydraulic braces hissing as he balanced his weight. "We're just passing through, Garrick. We don't want any trouble with your scrap-rats."

"Passing through?" Garrick laughed, a harsh, rattling sound that made his men chuckle. He pointed the tip of his heavy cleaver toward Marcus's harness. "Nothing passes through Sector 12 without paying the toll, borer. Especially not a pilot hiding a military-grade engine on his back. I can hear that G-Core humming from here. It’s cracked, sure, but the scrap-brokers in the mid-tier will pay a mountain of coal for that much raw G-energy."

Marcus leaned his head forward, his sharp, calculating eyes scanning the scavengers' armor. *Crude iron plating,* he noted, his military training instantly identifying the weaknesses in their gear. *Heavy and slow. Under 2G, those plates add fifty pounds of dead weight. They can't move fast, but they have numbers, and we're trapped in a narrow bottleneck.* He knew that a direct, prolonged battle would drain his G-Core to zero, leaving them completely defenseless before they could even reach the crashed vessel.

"We don't want your scrap, Garrick," Marcus said, his voice calm, clipped, and devoid of fear. He reached into his duster pocket, pulling out a small, lead-lined leather pouch. He opened it, revealing three raw G-Core shards. They glowed with a volatile, flickering blue light, casting eerie shadows across his pale face. "Three raw shards. High purity. That's more than enough to cover the toll for a simple passage."

Garrick stared at the glowing shards, his greedy eyes narrowing. For a second, he hesitated, but then his gaze shifted back to the heavy manual harness strapped to Marcus's shoulders. The blue radiation glow leaking from the G-Core's vents was too tempting.

"Shards?" Garrick spat, his sneer returning. "You think I'm a low-level gatekeeper, cripple? I want the engine. Unbuckle that harness and hand it over, or my boys will cut it off your corpse and dump what's left of you into the abyss."

"The engine keeps him alive, Garrick," Jax growled, his grip tightening on his drill. "You touch him, and I'll bore a hole straight through your chest."

"Is that so?" Garrick barked. "Get them!"

The scavengers charged, their heavy iron boots stamping the wet shale in a chaotic, thundering rhythm.

Jax reacted instantly. He lunged forward, his hydraulic leg braces screaming as he tried to push through the front line manually. But the crushing 2G gravity and the sheer physical numbers of the scrap-clad gang pinned him down. Two scavengers slammed their heavy iron poles against Jax’s shoulders, the impact driving him to his knees in the mud.

"Marcus, hold on!" Jax roared.

A third scavenger lunged from the side, swinging a heavy kinetic cleaver aimed directly at Jax’s neck. Jax raised his massive Titan-Borer Drill, the diamond teeth grinding against the cleaver in a deafening, screeching shower of orange sparks. The force of the blow rattled Jax’s arms, his steam pistons venting a thick cloud of super-heated steam as he fought to hold the block.

Behind them, another scavenger charged Marcus, his cleaver raised high.

Marcus had no choice. He couldn't stand, and his G-Core was already drained, but he couldn't let Jax take another hit. He locked his focus onto a massive pile of scrap steel plating—heavy, rusted iron sheets salvaged from an old ore hauler—resting against the cavern wall just five feet away.

*G-Inversion,* Marcus commanded, his mind aligning the G-Core's frequency with the mass of the scrap.

With a sharp, high-pitched whine, the G-Core beneath his harness flared violently, emitting a thick, blue ionizing glow. A sudden, agonizing wave of kinetic feedback surged up his spine, making his vision flicker into gray static. His calcified left knee joint seized, the rigid bone grinding painfully against his iron braces. A hot, fresh stream of blood began to leak from his nose, but he held his focus.

The massive pile of scrap steel plating suddenly became weightless, lifting off the wet floor and hovering silently in the air. With a sharp flick of his wrist, Marcus shifted the gravity vector, launching the heavy plates forward like a supersonic slingshot.

*Clang-crash!*

The heavy steel plates slammed into the charging scavengers, the kinetic impact throwing them back into the support pillars. The force of the blow shattered their crude armor plates, sending them sprawling into the mud.

But Marcus wasn't finished. He targeted Garrick directly. He focused a concentrated, high-G compression vector on the gang lord's chest, instantly multiplying his weight by five hundred pounds.

"Argh!" Garrick choked out.

The sudden, invisible downward pressure slammed Garrick to his knees, his massive cleaver slipping from his grasp as his chest was compressed. The wet shale beneath his boots cracked under the immense weight, his crude iron armor buckling and sparking as it resisted the pressure. He gasped for air, his face turning a deep, suffocating purple as his lungs refused to expand.

Marcus stared down at him, his face pale, blood dripping from his chin. His G-Core hummed weakly, the diagnostic screen flashing a critical warning: *Battery at fifteen percent.* His right collarbone felt as though it had been struck by a hammer, a sharp, cold micro-fracture sending agony down his arm. He held the gravity field for three more seconds, letting the absolute terror sink into Garrick's eyes.

"Tell your men to back off," Marcus rasped, his voice a cold, whispering promise of death. "Or I'll collapse your ribcage into your lungs."

Garrick looked up, his greedy confidence completely shattered by the display of invisible power. He had heard rumors of the 'Iron Ghost' in Sector 9, but he had never believed a cripple could wield such devastating force. He raised a trembling hand, gasping for breath.

"Hold... hold!" Garrick wheezed, his voice thin and desperate. "Back down! All of you... back down!"

The remaining scavengers, terrified by the sudden collapse of their leader and the hovering scrap metal, slowly backed into the shadows of the scaffolding, their cleavers lowered.

Marcus released the gravity field. The sudden release of pressure made Garrick collapse forward into the mud, coughing violently as his lungs greedily drew in the thick, sulfurous air. Jax stood up, his drill still humming as he stepped over the fallen gang lord, shielding Marcus with his massive frame.

"We're leaving," Jax growled, his eyes fixed on the retreating scavengers.

Garrick slowly pushed himself up, wiping the wet shale from his face. He looked at Marcus with a mixture of fear and lingering, bitter hatred. He let out a wet, rattling spit, his golden teeth catching the dim green light.

"You think... you think you're the only ones hunting that sky-boat, pilot?" Garrick sneered, his voice still shaky but filled with a malicious glee. "You think you can just stroll into the wreck and take that core?"

Marcus narrowed his eyes. "What do you mean?"

Garrick let out a dry, hacking laugh. "I already sold those tracks to Vaughn. He’s the slickest scavenger in Sector 12, and he’s got a whole pack of heavy rifles with him. He’s halfway to the chasm by now. By the time your big brawler drags your heavy, metal legs to that wreck, Vaughn will have already ripped that G-Core out of the reactor and sold it to the highest bidder in the mid-tier. Enjoy your scrap, cripple. You're already too late."

Garrick backed into the dark, his men melting into the shadows of the twisted scaffolding behind him, leaving Marcus and Jax alone in the silent, sulfurous tunnel.

Marcus's chest heaved as his G-Core's hum faded into a weak, clicking vibration. The energy reserves were down to a critical fifteen percent. His left knee was a rigid, unyielding rod of pain, and his left femur throbbed with every beat of his heart. Vaughn was ahead of them, armed and fast, and they had no elevator to return to the surface.

"Marcus," Jax said, his voice quiet and heavy. "Vaughn's got the head start. If he gets that core..."

"He won't," Marcus whispered, his jaw set in a hard, cold resolve. "We follow the tracks. We don't stop."
