Zane didn't let up, forcing his body to move with a desperate, frantic rhythm that pushed his nervous system to the absolute breaking point. The creature was a mathematical predator, built to calculate and counter, but Zane was becoming something it couldn't easily predict: a storm of pure, physical persistence.
He abandoned the outward manifestation of the crimson armor, realizing that any energy he threw at the creature was merely a meal. Instead, he turned his power inward. He coated his arms and legs in a high-pressure sheath of blood, forcing the liquid to act as an external musculature. His veins pulsed a violent, glowing red beneath his skin, his limbs slick with the dark, metallic-scented life force that now served as both his shield and his engine.
He wasn't just moving; he was detonating into motion.
Every punch he threw was backed by the hydraulic force of his manipulated blood. He swung at the creature's head, a heavy, physical blow that lacked the energy "flavor" the monster craved. The creature glided backward, its white eyes flickering as it recalculated. Zane didn't wait for it to settle. He used the blood-slicked soles of his feet to grip the stone floor and launched himself again, a blur of red-streaked fury.
"Subject is adapting," the cold, telepathic hiss grated against his mind. "Physical output exceeds projected biological limits. Structural failure imminent."
"Shut up!" Zane snarled, his voice a ragged edge of exhaustion.
He lunged, diving beneath a skeletal claw that carved a line of frost into the stone wall behind him. As he rolled, he lashed out with a kick, the blood-enhanced impact catching the creature's midsection. There was no satisfying crunch—it was like hitting a column of freezing smoke—but the force was enough to disrupt the creature's kinetic glide, sent it stumbling back into a row of medical cabinets.
Glass shattered. Vials of precious healing tinctures burst, the scents of lavender and pungent herbs filling the air. Zane used the momentary distraction to close the gap. He was a whirlwind of motion, weaving through the dark-matter fields the creature projected.
He knew his body was screaming. The Bio-Channeling was taxing his heart; he could hear it thumping in his ears like a war drum. But every second he stayed in this dance, every second those white voids stayed locked on him, was another second for Lyra to reach Kaelen.
The creature regained its balance and thrust its palms forward. A wave of anti-vitality rippled through the air—a gray, color-leaching distortion that made the very air feel heavy and dead. Zane didn't try to block it. He leapt upward, his blood-enhanced legs propelling him to the ceiling. He clung to a stone rafter for a heartbeat, his eyes burning with the effort of maintaining his focus.
"You are breaking," the creature hissed, sensing the tremors in Zane's muscles. "Your heart rate is critical. Surrender is the only logical path to preservation."
"I'm not looking for preservation," Zane wheezed, his vision blurring at the edges. "I'm looking for time."
He dropped from the ceiling, leading with his knees. The creature tried to phase through the attack, but Zane anticipated the kinetic shift. Mid-air, he shifted the flow of blood in his legs, causing a micro-burst of pressure that altered his trajectory. He slammed into the creature's shoulders, pinning it to the floor.
The coldness that radiated from the creature was agonizing. It felt like his very soul was being pulled into a freezer. His blood-sheath began to dim, the anti-vitality field leaching the life from his power.
Zane didn't pull back. He began to pummel the creature's featureless face with his bare, blood-slicked fists. Each strike was a testament to his resolve—a frantic, desperate rhythm of a man who had found his purpose in the heart of a nightmare.
"Lyra... please..." he thought, his consciousness flickering.
He was a ticking time bomb, and the timer was nearing zero. But as long as his heart beat, as long as his blood flowed, the door to the infirmary stayed shut. He was the Protector, and he would hold the line until there was nothing left of him to break. But he was reaching his limit.
"Subject....threat....threat....Subject is critical threat to assignment, must remove...."
The creature's white void-eyes pulsed with a sudden, strobing intensity. The analytical, cold voice in Zane's head didn't just hiss anymore; it screamed with the digital screech of a malfunctioning processor.
"PARAMETERS ALTERED. NEUTRALIZATION INSUFFICIENT. TERMINATION PROTOCOL INITIATED."
The shadow-form didn't just contract this time; it collapsed inward until it was a jagged, razor-thin sliver of absolute nothingness. The temperature in the infirmary plummeted instantly. The moisture in the air turned to frost, and the very light from the lanterns seemed to bend toward the creature, disappearing into its silhouette. It lunged, not with a glide, but with a spatial snap—appearing instantly in Zane's guard.
Zane's blood-sheath flickered. The cold was so intense his internal hydraulics began to seize. As the creature's skeletal hand thrust toward his chest—aiming for his laboring heart—Zane did something the Codex hadn't explicitly taught him, but his instinct demanded.
He didn't pull back. He compressed.
He pulled every drop of the external blood-armor into a single, localized point in the center of his chest. He created a dense, high-pressure knot of life-force directly behind his sternum. When the creature's fingers made contact, they didn't sink into soft flesh. They hit a biological diamond.
The impact sent a shockwave of raw, un-channeled kinetic energy through Zane's skeletal structure. He felt his ribs groan, one or two snapping with a sickening pop, but the "knot" held. The creature's void-energy clawed at the mass of blood, trying to leach it, but the pressure Zane maintained was so great the energy was literally too "compact" to be sucked away easily.
"ERROR. SOURCE IS UNYIELDING."
"Not... an error," Zane wheezed, blood trickling from the corner of his mouth. "It's... choice."
Using the creature's proximity, Zane wrapped his arms around the shadow-mass in a desperate bear hug. He ignored the frostbite blossoming across his skin. He channeled the last of his strength into his arms, squeezing the void-matter with the strength of a dying star.
The creature thrashed, its form flickering between solid and smoke. It began to emit a high-pitched, ultrasonic whine that vibrated Zane's teeth. The floor beneath them began to crack, the stone unable to withstand the localized gravitational pressure the creature was exerting to escape.
Then, the infirmary doors—already hanging by a single hinge—didn't just open. They vaporized.
A massive, golden shockwave of pure kinetic force slammed into the room, so precise it bypassed Zane entirely and struck the Shadow-Creature with the weight of a falling mountain.
"GET AWAY FROM MY STUDENT!"
Kaelen stood in the doorway. He looked like a man carved from thunder. His chest was still bandaged, and his arm was in a brace, but his eyes glowed with an incandescent, golden light that pushed back the darkness. Behind him, Lyra stood with Elias in her arms, her face a mask of tear-streaked relief.
The Shadow-Creature let out one final, telepathic screech of "Non-Optimal" before it was blasted off Zane. It hit the far wall with enough force to crater the stone, its form dissolving into wisps of black smoke as it struggled to maintain cohesion under Kaelen's relentless kinetic pressure.
Zane collapsed to his knees, the blood-sheath finally failing. The glowing red veins beneath his skin dimmed to a dull, bruised purple. His heart, finally released from the Bio-Channeling stress, stumbled into a slow, erratic rhythm.
He watched through blurred vision as the creature realized its mission was a failure. It didn't try to fight Kaelen. It folded into itself, becoming a tiny black dot that blinked out of existence, leaving behind only a patch of scorched, frosted stone and the lingering scent of ozone.
The silence that followed was deafening.
"Zane!" Lyra's voice was the first thing to break through the ringing in his ears. She sprinted across the room, nearly tripping over the debris. She slid to the floor beside him, her hands hovering over his frost-covered arms. "Oh god, Zane, your heart... stay with me. Breathe."
Kaelen approached slowly, his heavy boots crunching on the glass. The golden light in his eyes faded, replaced by a look of profound, weary fury. He looked at the wreckage of the infirmary, then down at Zane, who was shivering violently.
"You held the line," Kaelen said, his voice a low, somber rumble. He knelt beside Zane, placing a hand on his forehead. A small spark of warm, stabilizing energy flowed from his palm. "You did more than just survive. You learned to condense your core. You've moved faster than Subject Zero ever should have."
Zane looked up, his eyes barely staying open. He saw Elias in the corner, being tended to by a frantic nurse who had rushed in after Kaelen. She was breathing. She was safe.
"It... it wasn't... a faction," Zane whispered, his teeth chattering. "It was... the Facility."
Kaelen's jaw tightened. "I know. They've sent a Specter. An automated hunter. It means they've found us, Zane. The peace of the Sanctuary is over."
Zane felt Lyra's hand grip his. She was crying now, but her touch was the only warmth left in the world. He felt the darkness closing in—not the creature's void, but the simple, heavy weight of a body that had given everything.
"We have to... fight," Zane murmured, his head lulling against Lyra's shoulder.
"We will," Kaelen promised, his gaze turning to the shadows of the corridor. "But first, we heal. Tomorrow, the three cycles are irrelevant. Tomorrow, we prepare for a siege."
As Zane finally lost consciousness, the last thing he felt wasn't the cold of the monster, but the warmth of the Stabilizing Medium—Lyra's tears falling on his hand, and the knowledge that for today, the Protector had won.
