A fist wreathed in roaring, azure flames slammed into Kael's ribs.
The impact sounded like a thunderclap. Bone cracked. Kael was launched across the sparring arena, skidding through the dirt until his back slammed into the reinforced stone wall.
He coughed, spitting a glob of metallic-tasting blood onto the ground.
"Pathetic," a voice echoed across the stadium.
Instructor Vane lowered his smoking fist, the azure flames—his Attuned Resonance—flickering out. He looked at Kael with nothing but absolute disgust.
In the stands, hundreds of Adept-ranked students laughed. They wore the pristine white and gold uniforms of the Caelum Academy. Kael wore the dull gray of an Initiate. He had worn it for four years.
"Your reaction time is flawless. Your physical conditioning is peak," Instructor Vane sneered, adjusting his cuffs. "But you have no Core, Kael. You are a 'Hollow'. Without a Core to generate Resonance, you are just meat waiting to be slaughtered by the Dissonant beasts beyond the walls."
Kael didn't look down. He wiped the blood from his chin, his dark, calm eyes locking onto Vane. He pushed himself up, his muscles screaming.
He didn't care about the pain. He cared about the failure.
"I can fight," Kael said, his voice quiet but carrying across the silent arena.
"You can die," Vane corrected sharply. "You fail the Vanguard Exam. Again. Effective tomorrow, you are stripped of your Initiate status and reassigned to the Scrapper division. You'll clean the blood off the walls of the people actually protecting this city."
The laughter in the stands grew louder.
Kael's fists clenched so hard his knuckles turned white. No Core. A genetic defect. In a world where the size of your Resonance Core determined your worth, Kael was literally born empty.
Hours later, the sun set, bleeding red over the fortress city. Kael walked alone through the Outer Slums, carrying a bag of trash toward the incinerators. His ribs throbbed with every step.
Just meat, Vane's voice echoed in his head.
Suddenly, the air grew freezing cold. The hairs on Kael's arms stood up.
A shadow detached itself from the alleyway. It wasn't human. It was hulking, twisted, with jagged bone plating and eyes that glowed with a sickly, purple corruption. A Dissonant. A beast made of corrupted Resonance that had somehow slipped past the city's barrier.
Kael froze. He had no weapon. No Core.
The beast lunged, a blade of pure, purple energy forming on its forearm. It swung directly at Kael's neck.
Kael couldn't dodge in time. Pure instinct took over. He threw his bare hand up to block the fatal strike of corrupted energy.
He expected his arm to be severed. He expected to die.
Instead, the moment the purple energy touched his skin... it vanished.
Kael blinked. The beast froze, letting out a confused shriek.
The lethal blade of energy hadn't dissipated. It had sunk into Kael's palm. And deep within his chest, in the empty space where a Core was supposed to be, something dark and impossibly cold suddenly snapped awake.
That power... it wasn't human.
