Kael’s claws scraped stone as he grinned—an animal thing, triumph curdled with something he had no name for yet.
Then his legs gave out.
He hit the ground on one knee, and the crimson sky above him smeared into a wash of red and black, adrenaline draining out of him like water through cracked stone.
For long seconds he couldn’t move.
Then the pain found him: his shoulder throbbing in time with his pulse, ribs aching with every breath, legs trembling as though they’d forgotten their one job.
He lowered himself onto both palms.
Cold stone.
He breathed—once, twice, and the third breath came with a knife-twist through his ribs.
Exhaustion.
But this wasn’t the ordinary kind.
Something deeper had been hollowed out.
He pressed a claw to his chest, to the strange core that had been with him since the egg.
It was still there.
But it felt wrong—the dense warmth that used to pulse steady inside him now guttered like a dying coal.
Where did it all go?
He replayed the fight in fragments—every dodge, every strike, every time he’d wrenched his body past what it wanted to give.
Across the ruined ground, the demon he’d crippled still breathed, barely, one leg folded wrong beneath its bulk.
He didn’t go to it.
Not yet.
Blood was already unspooling into the air, and in the Abyss, blood was an invitation.
Something will come.
He forced himself upright, legs shaking, caught himself on a jagged spur of rock before he could fall again.
“Move,” he rasped—barely a voice at all.
One step.
Another.
Every one of them cost him something.
He needed somewhere small.
Somewhere the wounded thing couldn’t follow, and—more urgently—somewhere worse things wouldn’t find him first.
The Abyss unrolled around him in black stone and knife-edged cliffs, veins of crimson light bleeding through the cracks under a sky that never ended.
He walked without a destination, senses dulled but still catching everything: blood, ash, something metallic underneath.
And beneath that—demonic energy, thick in the air like an ocean he couldn’t see.
It’s everywhere.
So why am I empty?
Then he saw it: a narrow split at the base of a rock tower.
A cave, small enough to keep the larger demon out.
He crouched at the mouth, checked the dirt—no tracks, no fresh blood, no scent that shouldn’t be there—and waited.
Nothing answered.
One entrance.
Tight space.
Defensible.
Not perfect.
Good enough.
He slipped inside.
The tunnel dropped a few meters before opening into a small chamber, the air cooler, the crimson light dying before it reached the walls.
He ran his claws over the floor—dry, solid, untouched—and studied the stone: dark, streaked with faint red veins that pulsed, slow, almost like a heartbeat.
His stomach growled.
He ignored it.
Food could wait.
Staying alive couldn’t.
He sank against the wall, and the moment he stopped moving, exhaustion swallowed him whole.
Head down.
Limbs like lead.
He simply sat, breathing, listening, waiting for his body to stop screaming at him.
And then—something surfaced.
Not a voice.
Not words.
A memory that wasn’t his.
Inheritance.
He understood it now—fragments passed down through his bloodline, not the accumulated wisdom of some ancient demon, just the bare bones a newborn needed not to die.
And as he focused, another piece rose to meet him: The Abyss was steeped in demonic energy.
Demons drew it in naturally, a little at a time.
But absorbing wasn’t enough—it had to be circulated.
Pulled inward, sent to the soul core, stabilized there, pushed back out through the body, and returned again.
Over and over.
The cycle strengthened the bond between core and flesh.
It sped recovery.
Over time, it built power.
No deeper secrets.
No grand technique.
Just a foundation—the rest was his to build.
He smiled faintly.
Fine.
He’d never liked being handed the answers anyway.
He closed his eyes, straightened his spine, breathed—slow, deep—and reached inward.
Nothing.
He tried again, hunting for that strange substance in the air, and this time he caught it—thin as smoke slipping through his fingers.
He focused harder.
Draw.
Warmth trickled in.
At first, he couldn’t tell where the energy ended and his body began.
It wasn’t air.
It wasn’t heat.
It was something denser, something that seemed to press against his existence from every direction.
His eyes cracked open.
There—a thin thread moving through him.
Carefully, he guided it toward his chest.
Thump.
The core pulsed, and a wave of sensation nearly tore his control apart—the energy lurching toward his ruined shoulder, pain flaring white-hot.
He clamped down, stopped it cold.
Too much.
The inheritance hadn’t warned him.
He’d learned it the hard way: forcing too much energy through the core at once made the entire process unstable.
So he slowed.
Smaller amounts.
Tighter control.
Draw, guide, release—chest, spine, shoulders, arms, legs, and back again.
Crude.
Wasteful.
The energy slipped from his grip more than once, surged when it shouldn’t have, scattered his focus entirely.
But every failure taught him something, and he adjusted—a fraction less energy, a fraction slower, a different rhythm to his breath, a new path through his own body.
Old instincts surfaced without being asked: observe, correct, repeat, improve.
He didn’t need the whole system.
He just needed it to work.
Time bled away.
The Abyss kept no sun, no moon, no clock—only dark and that endless red glow.
When he finally opened his eyes, the exhaustion had pulled back.
Not gone.
Retreated.
His ribs still ached, his shoulder still screamed if he pushed it too far, but the deep weakness weighing down his body had lifted.
He flexed his claws.
They answered instantly.
He stood—slowly—and his legs held.
A few steps around the chamber.
No collapse.
No spin of vertigo.
The energy inside him felt steadier now, his core no longer a dying ember but something small and stubborn, clawing its way back.
He leaned against the wall, a thin smile breaking through.
Demonic energy isn’t just power.
It’s fuel.
And learning to control that fuel would matter as much as how much of it he ever held.
He glanced down at his shoulder, tested the movement—pain answered immediately, and he stopped.
The circulation had helped.
It hadn’t healed.
His body still needed time, and something in him settled at that.
If energy could mend wounds instantly, nothing would ever teach a demon to fear getting hurt.
Stronger demons probably circulated more efficiently.
If so, strength and control fed into each other.
A closed loop.
Then I’ll break into it.
His stomach growled again, louder.
His eyes drifted to the cave mouth.
The wounded demon.
Its core.
Hunger sharpened in him like a blade finding its edge.
He almost moved.
Almost.
Then stopped himself—still hurt, still spent, with no idea what else might be circling this place, and no idea what devouring a soul core would actually do to something as new as him.
His inheritance gave him the shape of the idea and nothing else: soul cores held concentrated power, consuming one could accelerate growth.
It said nothing about limits.
Nothing about what happened if the power was more than his body could hold.
Nothing about the dangers waiting in the space between those two facts.
I need information first.
He looked back toward the entrance one more time.
For the first time since he’d woken into this world, the choice in front of him wasn’t built out of fear.
He would stay.
Recover.
Circulate.
Watch.
And only then decide what to do with the demon bleeding out in the dark beyond his cave.
He settled into the most defensible corner of the chamber, back against stone, claws resting on his knees, and closed his eyes.
Somewhere out there, past the cave mouth, things stronger than the demon he’d already beaten were moving through the dark—stronger by a little, or by a magnitude he couldn’t yet imagine.
He didn’t know.
Not yet.
But he would.
His breathing slowed.
The energy around him stirred, and he pulled it in again.
Draw.
Circulate.
Return.
Again.
And again.
His first battle had taught him how to survive.
His first rest would teach him how to recover.
And soon—he would learn how to grow.
He opened his eyes one last time, found the faint outline of the cave mouth in the dark, and held it a moment.
Then let his eyes close again.
He wasn’t ready to face the Abyss.
Not yet.
But when he was, it would find him stronger than it expected.
