The abyss of the Warborn Dungeons did not echo. It swallowed.
Located seven levels below the permafrost of the estate, the isolation chambers were designed to break the minds of traitors. The walls were constructed of Null-Stone, a rare mineral that passively absorbed mana, light, and, most terrifyingly for Kaiser, sound.
When the heavy iron door slammed shut, sealing him inside the pitch-black cavern, Kaiser felt a momentary spike of true disorientation. For the first time since his rebirth, his "Absolute Senses" were muffled. When he clicked his tongue, the sound wave didn't bounce back to paint a mental map; the Null-Stone walls simply ate the vibration, leaving him with an incomplete, fuzzy wireframe of his surroundings.
He was eight years old, barefoot, dressed in a simple linen tunic, and entirely unarmed.
Kaiser stood perfectly still. The air was frigid and reeked of ozone, rotting marrow, and ancient rust. He controlled his breathing, slowing his heart rate to a steady, rhythmic thrum. Panic was a loud emotion; it tightened the vocal cords and made the blood rush. He needed absolute silence to hunt.
If the walls won't speak to me, Kaiser thought, lowering his stance, I will have to listen to the floor.
He pressed the soles of his bare feet flat against the freezing stone, expanding his sensory focus downward.
Thrum... crk... thrum.
There it was. It wasn't a heartbeat. It was a jagged, erratic scratching.
From the ceiling above, something was crawling.
"Rift Beasts," the Duke had called them. Creatures born from the chaotic tears in the Northern sky, possessing no natural biology. They were amalgams of corrupted mana and twisted flesh.
Kaiser tilted his head upward. He couldn't hear their breathing, but he could hear the static. The chaotic mana leaking from their bodies sounded like violently crinkling aluminum foil. It was a grating, high-pitched frequency that made Kaiser's teeth ache.
There were three of them.
The static grew louder. The air pressure shifted directly above him. They were dropping.
Kaiser didn't try to dodge out of the way; doing so in a room with distorted echolocation would mean stepping blindly. Instead, he dropped flat onto his back.
A massive mass of claws and fur crashed onto the stone exactly where he had been standing a millisecond prior. The impact shook the floor.
Before the beast could recover, Kaiser kicked upward with both legs, driving his heels directly under what sounded like the creature's jaw. The impact was solid, but it felt like kicking a wall of rubber. The chaotic mana absorbed the kinetic energy.
The beast let out a screech—a sound that was less an animalistic roar and more the screeching of tearing metal. A heavy, clawed appendage swiped blindly in the dark, grazing Kaiser's shoulder.
Warm blood instantly soaked his linen shirt. The pain was sharp, but Kaiser's mind remained a tranquil lake.
Physical strikes are useless. Their flesh is a shock absorber for their mana.
He rolled backward, putting ten meters between himself and the beasts. They were circling him now, their jagged claws clicking against the stone.
He needed a conductor. He needed a weapon that could channel vibration.
Kaiser swept his right foot in a wide arc across the dungeon floor, his toes brushing against debris. Dust, pebbles, shattered bone... and then, a heavy metallic clink.
He dropped to his knee and grabbed it. It was a broken length of iron chain, likely left over from a long-dead prisoner. It was rusted, thick, and heavy. About three feet long.
To a swordsman, it was garbage. To a maestro of vibration, it was a violin bow.
"Let's tune you," Kaiser whispered.
The three Rift Beasts lunged simultaneously. The symphony of their chaotic static merged into a deafening roar of corrupted magic.
Kaiser stood his ground. He gripped one end of the chain and channeled a pinpoint surge of his own pure, uncorrupted mana into the iron. He didn't use the mana to make the chain heavier or sharper. He used it to make the iron vibrate.
He began to spin the chain at his side.
Whirrrrrr.
As the iron cut through the air, it emitted a deep, subsonic hum. Kaiser adjusted the flow of his mana, tightening the frequency, matching it perfectly to the chaotic static emitting from the beasts.
Higher... higher... match.
The moment the humming of his chain perfectly mirrored the screeching static of the beasts, Kaiser moved.
He stepped into the arc of the first leaping beast and whipped the vibrating chain directly at its chest. He didn't aim to bludgeon it; he aimed for the dense cluster of chaotic mana he could hear swirling at its center—its core.
The iron links struck the beast's chest.
Because the chain was vibrating at the exact counter-frequency of the beast's core, the impact didn't bounce off. It violently disrupted the creature's internal magical structure.
A sickening, hollow POP echoed through the chamber.
The beast didn't bleed. It simply disintegrated. Its chaotic mana shattered like glass, turning the creature into a shower of black ash and dissolving flesh.
The remaining two beasts paused, their primitive instincts registering the sudden, unnatural death of their packmate.
Kaiser didn't give them time to adapt. His blood was up, a cold, predatory thrill racing through his veins. The black silk blindfold over his eyes remained perfectly in place, contrasting with the savage grin that stretched across his face.
He vanished into the dark. Using "Silent Step," he eliminated the friction of his own feet. He became a ghost armed with a tuning fork of death.
He appeared beside the second beast. Crack. The chain whipped against its skull, sending a concentrated shockwave directly into its brain. The creature collapsed, dead before it hit the floor.
The third beast panicked. It turned to scramble up the Null-Stone walls, its claws screeching in desperation.
Kaiser threw the chain like a javelin.
Guided perfectly by the acoustic signature of the beast's terror, the vibrating iron chain pierced the creature's spine, pinning it to the wall for a split second before the counter-frequency detonated its core. Black ash rained down on Kaiser's head, dusting his pure white hair.
Silence returned to the dungeon. Absolute, perfect silence.
Kaiser stood alone in the dark, breathing steadily. He reached up and felt his injured shoulder. It was a shallow cut, but the pain was a grounding reminder of his mortality. He dropped the rusted chain; it had fractured from the stress of channeling his mana.
He walked to the center of the room, sat down cross-legged on the cold stone, and waited.
Time was irrelevant to a man who couldn't see the sun. He sat in the sensory deprivation chamber for what felt like hours, simply listening to the slow, steady rhythm of his own heartbeat. He had survived. He had taken the first step toward conquering Aethelgard.
Eventually, the heavy grinding of iron gears vibrated through the floor. The immense dungeon door slowly swung open, letting in a flood of harsh torchlight that Kaiser could not see, but could feel against his skin as a wave of heat.
The heavy, mountainous footsteps of Duke Warborn echoed into the room, accompanied by the lighter, nervous steps of Sir Vane.
The Duke stopped. The silence stretched. Kaiser knew what they were looking at: an eight-year-old boy, blindfolded, sitting calmly in a pool of black ash, his white hair stained with dried blood.
"The Rift Beasts," Vane whispered, his voice trembling with a mixture of horror and awe. "They're gone. Completely annihilated."
"He didn't just kill them," the Duke said, his deep voice resonating with something dangerously close to pride. "He erased their mana. He unmade them."
Kaiser slowly stood up, turning his head toward the massive thermal signature of his father.
"The dark is an excellent teacher, Father," Kaiser said, his childish voice echoing coldly off the Null-Stone walls. "But it has nothing left to teach me."
Duke Warborn stared at his son, the heir who carried the curse of the Void Eyes.
"Come out of the dark, Kaiser," the Duke finally commanded. "Your childhood is over. It is time you learn the politics of power. Wash the blood off yourself. Tomorrow, the Elven King arrives, and you will meet your fiancée."
