The descent toward the Spire's geothermal vents felt like walking into the throat of a dying god.
They left the Red Shield bunker two hours before dawn. Elise had provided them with upgraded gear: localized EMP grenades for Isolde, a lighter, kinetic-absorbing vest for Ren, and a fresh cache of armor-piercing rounds for David's heavy pistol.
Saya took nothing.
She wore her torn uniform, Kai's leather jacket, and the heavy black cello case strapped tight across her chest. Her katana rested on her hip.
As they moved deeper into the bedrock beneath Neo-Paris, the ancient ossuaries of the catacombs gave way to massive, brutalist tunnels of reinforced concrete and rusted iron. The temperature began to rise dramatically. The air grew thick, smelling of sulfur, hot metal, and stagnant steam.
"We are close to the primary heat exchange," Ren whispered, checking the biometric scanner mounted to his wrist. He had to wipe sweat from the screen every few seconds. "The main vent shaft should be half a mile ahead. It leads straight up into the sub-basement of the Spire."
"Is the path clear?" David asked, his breathing heavy in the oppressive heat. He was using his cane with every step now, his bad hip grinding in the damp air.
"Thermal is useless down here," Ren said, frustrated. "The ambient temperature from the vents is masking everything. The walls are glowing on the monitor. If they are waiting for us, I won't see them until they're right on top of us."
Isolde clicked the safety off her rifle. She had swapped her long-range scope for a close-quarters holographic sight. "Keep your eyes up. They won't attack from the floor. They're hunters. They'll use the vertical space."
They entered a massive, cylindrical chamber.
It was a junction for the geothermal pipes—massive iron conduits the size of subway trains crisscrossed the cavern, pulsating with the heat of the earth's core. The roaring of steam vents drowned out their footsteps.
Catwalks of grated steel hung precariously over a seemingly bottomless, glowing abyss.
At the far end of the cavern, a massive circular blast door stood closed. The backdoor to the Spire.
Saya stopped at the edge of the first catwalk.
She didn't look at the door. She looked up into the tangled canopy of iron pipes and hissing steam above them.
The dust on her back was silent, heavily suppressed by her will, but her own innate senses—honed by a century of warfare—were screaming.
The air didn't just smell like sulfur. It smelled like ozone. Like static electricity before a lightning strike.
"Form up," Saya said quietly. Her hand rested on the hilt of her sword. "Backs to the wall."
David and Isolde didn't question her. They instantly fell back, forming a tight defensive triangle around Ren, pinning their backs against the concrete entrance of the tunnel they had just exited.
"I don't see anything," Ren shouted over the roar of the steam.
"Look closer," Saya said.
A shadow detached itself from a pipe forty feet above them.
It didn't drop. It glided.
It landed on the grated catwalk ten yards away with absolutely zero sound. No clatter of boots. No heavy thud. Just a silent, predatory crouch.
As the steam parted, the red emergency lights of the cavern illuminated the creature.
It looked exactly like a teenage boy. He wore a sleek, skin-tight tactical suit woven from some sort of black, kinetic-absorbing mesh.
His hair was a shock of brilliant, sterile silver.
His skin was pale, flawless, completely devoid of the creeping red cracks of the Thorn that had plagued the original Schiff.
But his eyes were the true nightmare.
They were glowing a fierce, synthetic blue. There was no soul in them. No anger. No tragedy. Only the cold, empty obedience of a machine.
"Project Resurgent," David gritted his teeth, raising his pistol.
The silver-haired boy stood up. He slowly raised his arms. With a sickening, organic schlick, two jagged blades of crystallized, violet blood extruded from his forearms, extending past his wrists like deadly, glowing scythes.
"He's not alone," Isolde warned.
From the shadows above, more figures dropped.
Three. Five. Eight. Ten.
A pack of ten flawless, stabilized Schiff clones surrounded them, dropping onto the catwalks, the pipes, and the support beams.
Their blue eyes cut through the steam like lasers. They moved with a terrifying, synchronized hive-mind precision, their blood-blades extending in perfect unison.
There was no battle cry. No taunts.
The lead Schiff simply tilted his head, and the pack attacked.
They were unbelievably fast.
Isolde fired. Her rifle boomed in the enclosed cavern. A high-explosive round struck the lead Schiff in the chest.
In the old days, that shot would have torn a Chiropteran apart. But the boy didn't even break his stride. The kinetic mesh of his suit absorbed the explosive force, and the stabilized biology beneath it instantly knit the fractured ribs. He lunged at Isolde, his blood-blade aimed at her throat.
Isolde dropped to her knees, leaning backward as the glowing violet blade sheared the top of her hair off. She drew her sidearm and fired three rounds upward into the boy's jaw, but he twisted in mid-air, landing on the wall behind her like a spider.
"They heal too fast!" Isolde shouted, rolling out of the way as the boy launched himself again.
David fired steadily, dropping a Schiff that had tried to flank Ren. The heavy slugs knocked the creature off the catwalk, sending it tumbling into the abyss below. But before David could track another target, a Schiff dropped directly from the pipe above him.
The clone's foot slammed into David's bad hip. The old man cried out, his leg giving way. He hit the grating hard, his pistol skittering across the metal. The Schiff raised its arm-blade for the kill.
CLANG.
Saya intercepted the strike.
Her katana sparked violently against the Schiff's violet blood-blade. The sheer kinetic force of the parry sent a shockwave through the catwalk.
She looked into the boy's glowing blue eyes.
She remembered Moses. She remembered Karman. She remembered the desperate, tragic children who had fought so hard just to live long enough to see the sun without burning to ash.
Chimera had taken their desperation and erased it. They had stripped the humanity from the genome and left only the weapon.
I will grant them silence, she thought.
Saya pushed the Schiff's blade aside, spun, and slashed her sword across her own left forearm.
Her Queen's blood welled up, coating the steel of her katana.
The sword hissed, instantly transforming from regular steel into a lethal, crystalline weapon capable of shattering Chiropteran cells.
"Cover David!" Saya shouted to Ren.
She didn't wait for the pack to swarm her. She became the storm.
She launched herself off the catwalk, launching toward the cluster of three Schiff advancing on Isolde.
They swung at her in unison, a deadly net of violet blades.
Saya's movements were fluid, absolute, and devoid of the frantic, dust-fueled rage she had relied on in Siberia. She dipped under the first strike, her blood-coated sword slicing clean through the boy's torso.
As her Queen's blood mingled with the stabilized clone's biology, the reaction was instantaneous. The boy froze. The violet glow of his blades flickered and died. His body rapidly crystallized into brittle, gray stone, before shattering into a cloud of ash that was instantly sucked away by the cavern's ventilation drafts.
One down. Nine to go.
The other two adjusted instantly, calculating her lethality. They didn't retreat; they pressed the attack, striking with mechanical fury.
Saya parried a thrust, the impact vibrating up her arm, and used the momentum to vault over the second Schiff. She landed lightly on a massive steam pipe running parallel to the catwalk.
The Schiff followed her, leaping twenty feet into the air without hesitation.
Saya waited until they were airborne, at the apex of their jump. She swung her sword in a wide, horizontal arc.
SHING.
She severed the legs of one, and the arm of another. Her blood crystallized them before they even hit the ground. They shattered against the iron pipes like glass dolls.
Down on the catwalk, Isolde had recovered her footing. She realized bullets were useless unless they hit the brain stem. She holstered her rifle, drawing twin combat knives. She moved with ruthless, military precision, weaving through the attacks of two Schiff, redirecting their momentum.
"Ren! The EMP!" Isolde yelled, ducking under a decapitating strike.
Ren, huddled over David, grabbed one of the grenades Elise had given them. He pulled the pin and hurled it toward the center of the catwalk.
The EMP detonated.
It didn't harm the biological clones, but it instantly fried the kinetic-mesh suits they were wearing. The black armor sparked and smoked, suddenly turning heavy and rigid, stripping the Schiff of their shock-absorption.
"Now!" David roared from the floor, having retrieved his pistol. He fired a three-round burst. Without the mesh to absorb the impact, the heavy slugs tore through the knee joint of a Schiff, bringing it down. Isolde was on it in a flash, driving her knives into the base of its skull, severing the spinal cord.
Five left.
They realized the ground team was heavily defended. The remaining Schiff locked their glowing blue eyes onto the single greatest threat in the room.
The Queen.
All five converged on the steam pipe where Saya stood.
They moved like a single organism. They attacked from the front, the back, and above.
Saya didn't have the space to swing her sword.
One Schiff lunged, driving its blood-blade toward her chest. She twisted, the blade grazing her ribs, slicing through the leather jacket. Another dropped from above, aiming for the cello case on her back.
Her eyes widened.
She threw herself backward, taking a shallow cut to her shoulder rather than letting the blade touch the case. She fell off the steam pipe, plummeting toward the abyss below.
The five Schiff dove after her.
They were in freefall.
The heat rising from the geothermal vents roared in her ears. The orange glow of the earth's core illuminated the falling combatants.
Saya didn't panic. She didn't reach for the dust.
She focused her breathing. She found her center in the air.
As the closest Schiff reached her, thrusting its blade down, Saya grabbed its wrist. She used the clone's own falling momentum, pulling it forward and driving her blood-coated sword straight up through its chin.
It crystallized instantly.
She used the shattering, stone-like body as a springboard. She kicked off the crumbling corpse, arresting her fall and launching herself horizontally toward the massive concrete wall of the vent shaft.
She hit the wall hard, her boots finding purchase on a narrow maintenance rung embedded in the concrete.
The remaining four Schiff hit the wall around her, clinging to the concrete like insects.
They swarmed her.
It was a brutal, vertical knife-fight over a lake of fire.
Saya parried, slashed, and dodged. She felt a blade pierce her thigh. She felt another slice across her cheek. The pain was sharp, intense, and grounded her entirely in the moment.
She severed the arm of one Schiff, kicking it backward into the void. It fell silently into the glowing orange depths.
Three left.
They pressed her against the concrete. They were too fast, too perfectly coordinated. A violet blade plunged toward her heart.
Saya let go of her sword with her left hand. She caught the Schiff's blade with her bare palm.
The violet energy seared her flesh, burning down to the bone, but she didn't let go. She clamped her grip tight, locking the clone in place. With a primal shout, she drove her katana through its chest, letting her Queen's blood turn its heart to stone.
Two left.
They hesitated. For the first time, a flicker of something resembling confusion crossed their synthetic blue eyes. They were programmed to fight flawless, calculated battles. They were not programmed to comprehend an enemy who would willingly burn her own hand to the bone just to secure a kill.
That hesitation was all Saya needed.
She ripped her sword free from the crumbling statue. She pushed off the wall, launching herself directly between the final two clones.
She spun in mid-air—a perfect, horizontal cyclone of steel and blood.
The blade sheared through both of their necks simultaneously.
They didn't even have time to fall. They crystallized in mid-air, shattering into two clouds of gray ash that drifted down into the roaring heat of the abyss.
Saya grabbed a hanging chain to stop her fall, swinging back toward the main catwalk.
She landed heavily, dropping to one knee.
Her breathing was ragged. Her uniform was slashed in a dozen places. Her left hand was a charred, bleeding ruin, the flesh burned black by the Schiff's energy blade.
But she was alive. And the cavern was quiet, save for the hissing steam.
Ren ran across the grating, sliding to his knees beside her. "Saya! Your hand!"
"It will heal," she gasped, her voice tight with pain.
She looked down at her burned palm. Without the rapid regeneration of the dust, the injury would take days, maybe weeks, to fully repair. But the pain was a badge of honor. It was proof that she had survived on her own terms.
David limped over, supported by Isolde. He looked at the empty catwalks, at the ash dusting the iron pipes.
"Ten Resurgents," David said, his voice filled with awe and horror. "In less than three minutes."
Isolde looked down at Saya. The sniper's eyes lingered on the heavy black cello case strapped to Saya's back. It was completely untouched. Not a single scratch marred the leather.
"You didn't use him," Isolde said softly.
"No," Saya replied, slowly pushing herself to her feet. She sheathed her sword. "I did not need to."
She turned her gaze to the massive, circular blast door at the end of the cavern. The entrance to the Spire.
Ren followed her gaze. He pulled out a specialized decryption drive Elise had given him. "This is it. The geothermal access hatch. Once we go through this door, we're inside the arcology. There's no turning back."
"We are not turning back," Saya said.
David adjusted his grip on his cane. He looked old, battered, and incredibly tired, but his jaw was set with iron resolve. "Let's finish this. For Joel. For the Shield. For everyone they've broken."
Ren stepped up to the blast door. He plugged the drive into the maintenance terminal. The screen flashed green. Heavy hydraulic locks began to disengage with a series of deafening, echoing thuds.
Hiss.
The heavy steel door split down the middle, slowly pulling apart.
Instead of the dark, rusted tunnels of the catacombs, blinding, pristine white light spilled out into the cavern.
Beyond the door lay the subterranean maintenance levels of the Chimera Spire.
The floors were polished white composite. The walls were lined with seamless, humming server banks and spotless glass corridors. It was a sterile, futuristic fortress built on top of a graveyard.
Saya stood in the threshold.
The heat of the catacombs was behind her. The cold, calculated future of the Spire lay ahead.
She reached up with her good hand and touched the strap of the cello case one last time.
I am here, Hagi, she thought, not broadcasting the resonance, just whispering it into her own soul. I am ready.
Saya Otonashi stepped through the blast door, leading her broken, battered family into the belly of the beast.
