The rain did not fall in District 13; it decayed. It drifted down from the iron-grey sky in a greasy, acidic mist that hissed against the rusted gantry cranes and turned the coal dust on the docks into a slick, black paste. On the cracked concrete of Sub-district 4 Docks, Jack Mercer lay on his side, his breath coming in ragged, shallow gasps. Every intake of air tasted of sulfur and ozone.

His right hand was a ruined, swollen mass of purple flesh, the fractured bones in his palm grinding together like broken glass beneath the wet, torn layers of medical tape. His left shoulder was a map of deep, burning lacerations where Razor Ray’s monomolecular blades had peeled away his stone-like defense. At his neck, the DIY Neural Collar shrieked with a high-pitched, erratic vibration, its electrodes biting deep into the raw, blistered skin at the base of his skull. The water from the flooded shipping container had seeped into the casing, shorting out the electromagnetic pulses that kept the monster in his head asleep. The battery indicator on his wrist-link was a fading amber sliver, hovering at a critical fifty percent.

*"Let me out, cop!"* Brick Malone’s voice roared from the dark, locked corridors of his mind, no longer a gravelly whisper but a deafening, abrasive screech. *"Sledge is here! He’s gonna paste us into the concrete! Let me take the wheel! I’ll turn this aching, broken body of ours to granite, and we’ll cave his skull in! Let me out!"*

Jack squeezed his eyes shut, his left hand tensing as his fingers closed around the cool, tarnished silver of Sarah’s locket through his wet duster. The physical contact was his only grounding wire. *No,* he thought, his teeth grinding until his jaw ached. *I am Jack Mercer. I am a detective. I control the shell. I don't need you, Malone. I just need your strength.*

Through the heavy fog, Sledge stepped forward. The massive, cybernetically augmented enforcer was a terrifying silhouette against the pale pink neon glow of the Gilded Sector platform hovering high above the slums. His face was partially obscured by a heavy metal jaw plate that glinted in the greasy light. In his massive, reinforced hands, he carried a custom-built pneumatic sledgehammer. The hydraulic lines running along the weapon’s shaft hissed softly, venting high-pressure steam that mixed with the freezing rain.

"You killed Brick," Sledge said, his voice a low, mechanical rumble that vibrated through the concrete pier. He didn't rush. He didn't need to. He stepped over the unconscious, broken body of Razor Ray, his heavy boots leaving deep, muddy prints. "He was a brute, but he was family. The Seven don't let family go unavenged, Mercer. I'm going to paint this pier with your brains, and then I'm going to take that data drive from your cold pocket."

Jack looked at Moose, who was slumped against a rusted iron bollard ten feet away. The giant pit-fighter’s cybernetic right arm was completely severed at the shoulder, hydraulic fluid leaking into the chemical puddles like dark, iridescent blood. Moose’s organic eye was wide with pain and exhaustion, his chest plate sparking violently from the saltwater exposure. He was completely disabled, unable to assist.

*The manifest,* Jack thought. His left hand slipped into his inner pocket, verifying the cold, wet rectangle of the data drive was still secured beside Sarah's locket. He couldn't fight Sledge here. Not on the open pier with his concrete armor cracked, his collar failing, and Moose unable to move. He needed to change the geography of the battle. He needed a place with narrow corridors, structural choke points, and tools he could use.

His eyes scanned the concrete floor. Two feet away lay one of Razor Ray's dropped monomolecular knives, its silver blade glowing with a faint, deadly light. Jack's detective mind, hyper-focused despite the agonizing static in his head, formulated a plan. He slid his left foot forward, kicking the knife closer, then knelt down as if collapsing from his injuries. With a swift, practiced movement, his left hand swept the knife off the ground and slid it deep into his duster sleeve.

"Moose," Jack rasped, his voice deep and gravelly as Malone's persona attempted to bleed into his vocal cords. "Get up. We have to move."

"Jack... I can't," Moose grunted, his teeth chattering. "My legs... the feedback..."

Sledge raised the massive sledgehammer, the hydraulic lines hissing with high-pressure steam as he stepped over the shattered concrete. He swung the hammer backward, preparing for a devastating ground-slam that would collapse the entire pier.

Jack didn't wait. He lunged toward Moose, grabbing the giant’s left shoulder with his sprained left hand. He activated *Concrete Hardening*, his eyes flashing a brilliant, unstable blue (Blue Sclera Flash). The stone-grey armor spread across his legs and back, giving him the physical density needed to lift Moose’s massive frame. With a guttural roar, Jack dragged Moose backward into the labyrinth of rusted shipping containers just as Sledge’s hammer struck the ground.

*BOOM.*

The impact was colossal. A shockwave of shattered concrete and iron shards erupted from the pier, the force throwing Jack and Moose forward into the fog. The pier behind them groaned, the concrete splitting in half and collapsing into the toxic, black waters of the river below.

Jack didn't look back. Carrying Moose, he stumbled through the narrow gaps between the containers, his boots splashing through the acidic puddles. His right hand was a white-hot fire, the concrete skin forcing the fractured bones in his palm to grind together with every step. His collar screamed against his neck, the battery indicator dropping to forty-five percent.

"Where... where are we going?" Moose wheezed, his head hanging low.

"Your gym," Jack rasped, his breath hitching. "It's three blocks away. Heavy iron doors. Concrete basement. We barricade inside, repair your arm, and trap Sledge in the narrow corridors."

They moved through the dark, rain-slicked alleys of District 13, a pair of bleeding, broken ghosts escaping the hunter. The fog was their only cover, masking their trail from Sledge’s thermal scanners. By the time they reached the heavy iron basement doors of Moose’s Underground Gym, Jack’s concrete armor had peeled away, leaving his skin raw, blistered, and bleeding. He collapsed against the metal door, his chest heaving.

Jack used his left hand to beat a frantic, rhythmic code against the iron plate.

A second later, the heavy bolts slid back. Sledge, one of Moose’s veteran trainers, opened the door, his eyes widening in horror as he saw his boss’s severed arm and Jack’s ruined face.

"Get him inside!" Jack commanded, dragging Moose through the threshold. "Barricade the doors! Sledge is coming!"

Inside, the gym was a cavernous, concrete basement filled with the smell of sweat, leather, and ozone. Several underground pit-fighters were training near the boxing rings, their heavy cybernetics clinking in the dim, yellow light. They dropped their punching bags and sparring gear, rushing toward Moose with expressions of shock and panic.

"Moose! What happened to your arm?" a young fighter named Sledge asked, his voice trembling.

"Razor Ray," Moose grunted, as they lowered him onto a heavy wooden bench. "But Ray is done. It's Sledge we have to worry about. He's Malone's enforcer. He's tracking us."

Jack turned to Sledge, the trainer. "The doors. Lock them. Weld them if you have to. We need time."

"We have an industrial solder-gun in the back," Sledge said, rushing toward the maintenance cage. "I can seal the steel brackets."

But they were out of time.

*CLANG.*

The heavy iron doors of the gym vibrated violently, the impact of a massive physical force echoing through the concrete basement like a thunderclap. The steel brackets groaned, the rivets popping and flying across the room.

*CLANG.*

Another strike. The iron doors buckled inward, a wide gap opening at the center. Through the crack, the cold, wet fog of the slums drifted into the warm, sweaty air of the gym.

"Get the fighters into the back rooms!" Jack ordered, his detective mind taking absolute command. "Lock the security cages! Sledge’s hammer will collapse the ceiling if he swings it in the open gym! We have to contain him!"

"No, Jack," Moose grunted, trying to stand with his single arm. "This is my gym. My people. We fight."

"You can't fight!" Jack shouted, turning to face him. "Your arm is severed, your chest plate is shorting, and Sledge’s hammer relies on a high-pressure hydraulic line to power its strikes! If he hits your cybernetics, the electrical feedback will fry your brain! Get to the back! Let me handle him!"

Before Moose could answer, the iron doors were blown off their hinges.

Sledge stepped through the ruined doorway, his massive duster coat dripping with rain, his pneumatic sledgehammer resting on his shoulder. His metal jaw plate glinted in the dim yellow light as his cold, mechanical eyes scanned the room, locking onto Jack.

"A gym," Sledge said, a cruel, metallic chuckle escaping his throat. "A fitting place for a slaughter. I see your little friends are here, Moose. Good. They can watch me break your detective piece by piece."

Sledge swung the massive hammer down, the pneumatic piston firing with a loud *HISS* of steam as he stepped forward. He didn't target Jack first. He targeted the concrete support pillar nearest to the entrance.

*BOOM.*

The hammer struck the pillar, the concrete instantly shattering into dust. The heavy iron rebar bent, and the ceiling above groaned violently, a shower of plaster and stone debris falling onto the boxing rings.

"He’s trying to collapse the gym!" one of the fighters screamed, panicking as they fled toward the back security cages.

"Stand back!" Jack yelled to the remaining fighters.

Jack tensed his muscles, forcing the concrete-hardening power to activate once more. His eyes flashed blue, and the raw scar on his neck flared with a blinding light. The stone armor spread across his body, but the physical strain was immense. His collar screamed, its battery dropping to thirty-five percent. The *Dual Soul Strain* was beginning to take its toll; a severe tremor ran through his left leg, and glowing blue veins flickered on his temples as Malone's voice raged inside his skull.

*"Let me take the hand, Jack! Let me strike! I'll break his hammer with our bare knuckles! Let me out!"*

*No,* Jack thought. *Malone’s brute force is what Sledge expects. I have to use my mind.*

Sledge lunged forward, swinging the hammer in a wide, horizontal arc. Jack activated *Concrete Hardening*, raising his left arm to block.

*CRACK.*

The hammer struck Jack’s stone-hardened shoulder. The impact was devastating, the pneumatic force of the blow throwing Jack across the room. He crashed through the wooden ropes of a boxing ring, his concrete armor cracking under the pressure. The stone grey texture on his shoulder shattered, leaving his raw flesh underneath bruised and bleeding.

Jack groaned, trying to stand, but his right hand was completely paralyzed by the pain. Sledge stepped into the ring, raising the hammer for a crushing downward strike.

"You're slow, Mercer," Sledge mocked. "Brick's power was meant for a giant, not a washed-up cop with a leaking brain."

Moose, watching from the bench, grabbed a heavy steel barbell with his left hand. With a guttural roar, he threw it at Sledge’s head.

Sledge didn't even turn. He raised his heavy cybernetic left shield, blocking the barbell with a loud *CLANG*. The impact knocked Moose back, his short-circuiting shoulder sparking violently as he collapsed back onto the bench.

"Moose!" Jack shouted.

Sledge turned back to Jack, his hammer raised. "No more distractions."

Jack’s detective mind, operating in the slow-motion clarity of absolute survival, analyzed Sledge's stance. *The hammer relies on a high-pressure hydraulic line. The main line runs from the compressor tank on his back, down the underside of his right arm, and into the hammer's pneumatic core. It’s shielded by steel mesh, but the connection joint at the wrist is exposed when he extends for a full swing.*

Jack had Ray’s monomolecular knife slid deep into his left sleeve. He couldn't use his right hand—the fractured bones made it impossible to grip. He had to bait Sledge into a full downward swing, expose the wrist joint, and slice the line with his left hand.

It was a high-risk gamble. If he missed, the hammer would crush his skull.

Jack slowly dragged himself up, pretending to stumble, his concrete armor flickering and fading to make himself look completely defeated. He held his left hand over his chest, hiding the glint of the monomolecular blade beneath his wet duster.

"Is that... all you've got?" Jack wheezed, spitting blood onto the canvas. "Malone... was stronger than you."

Sledge’s eyes flared with anger. "Malone is dead! And you're joining him!"

Sledge lunged, bringing the massive sledgehammer down with both hands, the pneumatic piston firing at maximum pressure. The air pressure alone was suffocating, a heavy wind that tore at Jack's duster.

Jack waited. *One millisecond. Two.*

Just as the hammer was inches from his face, Jack activated *Density Anchor*, locking his feet to the canvas and throwing his upper body to the left.

The hammer struck the canvas floor of the boxing ring.

*BOOM.*

The wooden platform shattered, the heavy support beams beneath caving in as a cloud of dust and canvas fibers exploded upward. Sledge’s arms were fully extended, his wrist joint exposed as the hammer's head sank into the ruined floor.

Jack’s left hand shot out from beneath his duster.

The monomolecular blade, glowing with a cold, deadly light, sliced through the air. Jack targeted the exposed hydraulic joint at Sledge’s right wrist.

*SHHH-T.*

The monomolecular edge cut through the steel-mesh shielding like wet paper, severing the high-pressure hydraulic line.

Instantly, a geyser of superheated hydraulic fluid and steam erupted from the severed line. The hot, oily mist sprayed directly into Sledge’s face, hissing against his metal jaw plate and blinding his optical sensors.

Sledge screamed, a metallic, distorted shriek of agony as he stumbled backward, dropping the hammer. The pneumatic weapon, deprived of pressure, lay dead in the ruined canvas, its steam venting harmlessly into the air.

"My eyes!" Sledge roared, clawing at his face with his cybernetic left hand. "You bastard! I'll kill you!"

Jack didn't give him the chance. He stepped forward, his eyes glowing with a stable, deep blue as he synchronized his focus. He channeled Malone's remaining brute force into his ruined right hand. He didn't care about the pain. He didn't care about the fractured bones. He wrapped his fingers into a tight fist, the concrete armor shifting and hardening over his knuckles, turning into a solid, jagged block of stone (Stone-Fist Strike).

*"Yes!"* Malone's voice screamed in his head, a wild, ecstatic roar. *"Shatter him!"*

Jack delivered a devastating, wall-shattering punch directly to the core of Sledge's dead pneumatic hammer, which was still wedged in the floor near Sledge's chest.

*CRACK-BOOM.*

The Stone-Fist Strike struck the hammer's central pressure chamber. The remaining compressed air inside the tank exploded outward, the blast shattering Sledge’s cybernetic chest plate and throwing the giant enforcer backward through the boxing ring’s ropes.

Sledge crashed onto the concrete floor of the gym, his cybernetics short-circuiting, his duster coat smoking from the blast. He lay on his back, his chest plate torn open, his mechanical jaw plate twisted and hanging loose.

Jack stood over the gap in the ring, his concrete armor slowly peeling back. His right hand was bleeding profusely, the skin split open and the bone fragments completely displaced. The pain was a blinding, white-hot fog, but he forced his legs to carry him down to the concrete floor. He stood over the dying enforcer, his breath rattling in his chest.

His collar hummed weakly, its battery dropping to twenty percent.

"It's over, Sledge," Jack rasped, his own voice returning, cold and hollow. "The Seven are done. Tell me where the distribution hub is. Tell me who ordered the hit on Sarah."

Sledge let out a wet, bubbling laugh, blood leaking from the corners of his mouth beneath his twisted jaw plate. "You... you think you've won, detective?"

"Tell me!" Jack demanded, kneeling down and grabbing Sledge’s collar with his left hand.

Sledge's mechanical eyes flickered, the red light fading. "You're too late, Mercer. While you were playing hero at the docks... the Seven were already cleaning up the streets. Your little bird... the street kid..."

Jack’s heart stopped. His fingers tightened on Sledge’s coat. "Leo? What did you do to Leo?"

"The Pyro... Victor Vance... he took him," Sledge whispered, his voice fading into a mechanical rattle. "He’s already at the Silent Ward. The Needle... is preparing the syringes. By sunrise... the kid’s mind will be nothing but data... and you'll have nothing left to save."

Sledge’s eyes went completely dark. His body went limp, his head rolling to the side.

Jack stood up slowly, the silence of the ruined gym pressing down on him like a physical weight. Sledge’s dying words echoed in his head, a ticking bomb that threatened to shatter his remaining sanity.

*Leo.*

He turned to look at Moose, who was staring at him with a mixture of pain and horror. The gym was in ruins, the ceiling groaning, the iron doors destroyed. His primary safe haven was gone. His hand was ruined, his collar was dying, and his young scout was strapped to an extraction gurney.

Jack reached into his pocket, his trembling left hand closing around Sarah’s silver locket. He popped the latch, staring down at her fading photograph in the dim yellow light.

*I’m coming, Leo,* Jack thought, his jaw clenching as a cold, resolute fire replaced the panic in his chest. *I’m coming.*
