Ren pushed himself up slowly, his arms trembling under his own weight. Pain flared through his body instantly, forcing a sharp breath from his lips.
"Don't move!" Lira snapped, grabbing his shoulder. "You're barely holding together!"
He let out a weak chuckle. "If I stay down… I might not get back up."
"That's exactly why you should stay down!"
But Ren was already looking past her.
At the center of the shattered guardian.
Something pulsed.
Slow.
Heavy.
Alive.
The remains of the creature had collapsed inward, forming a jagged crater of broken stone and bone. At its heart, a dark crystal throbbed with dim, crimson light—each pulse sending faint ripples through the air.
The same runes that once covered the guardian flickered across its surface.
Dying.
But not gone.
Lira followed his gaze and stiffened. "No."
Ren blinked. "No?"
"You're not touching that," she said firmly. "I mean it this time."
He didn't argue immediately.
But his chest tightened.
His core pulsed.
Stronger than before.
Sharper.
Hungry.
Ren's expression shifted.
"…It's reacting."
"That's exactly the problem!" Lira shot back. "Every time your core 'reacts,' you almost die!"
"Yeah," he said quietly. "But it also saved me."
Silence fell between them.
Heavy.
Uncomfortable.
Ren stepped forward.
Lira grabbed his arm again. "Ren—"
"I'll be careful."
"You said that last time!"
"And I meant it this time too."
She hesitated.
Then slowly let go.
"…If something goes wrong, I'm dragging you out whether you like it or not."
A faint smile touched his lips. "Deal."
The closer he got—
The heavier the air became.
Each step felt slower.
Like the chamber itself was watching him.
Judging him.
His core pounded.
Not weak.
Not fading.
But… responding.
The crystal pulsed faster.
Ren stopped at the edge of the crater.
For a moment—
He just stared at it.
"…This thing," he murmured, "it's not dead."
Lira's voice dropped. "Then why is it still here?"
Ren didn't answer.
Because he wasn't sure he wanted to.
He stepped in.
The moment his foot crossed into the crater—
The world shifted.
The air turned cold.
Heavy.
Silent.
His core flared violently.
"Ghh—!"
Ren dropped to one knee, clutching his chest as a surge of energy rushed through him.
Not like before.
Not wild.
Not chaotic.
Focused.
The crystal pulsed—
And something pressed against his mind.
A presence.
Ancient.
Immense.
Watching.
"…You're still here," Ren whispered.
The pressure increased.
Not crushing.
But testing.
His vision blurred.
The chamber faded.
Darkness.
Endless.
And in it—
A shape.
The guardian.
Whole.
Standing before him once more.
Ren exhaled slowly.
"…Figures."
It didn't attack.
Didn't move.
It simply watched him.
Then—
It stepped forward.
The ground beneath Ren cracked.
Pressure surged.
His legs trembled.
"…What do you want?" Ren asked, his voice steady despite the strain.
Silence.
Then—
A single thought echoed in his mind.
"Endure."
The pressure doubled.
Ren's body shook violently.
His core screamed.
Cracks burned like fire spreading through his chest.
"GHH—!"
He dropped both hands to the ground, teeth clenched as the force bore down on him.
This wasn't a fight.
It was a test.
"Damn it…" he growled. "You call this… a trial?!"
The pressure increased again.
His vision darkened.
His breathing grew ragged.
His body was already broken from the fight—
Now this?
"…No…" he whispered.
"I didn't survive that… just to fall here…"
His fingers dug into the ground.
His core pulsed.
Weak.
Cracked.
But—
Still his.
Ren forced himself up.
Slowly.
Painfully.
Every inch felt impossible.
But he stood.
The pressure didn't stop.
Didn't ease.
It grew.
"Is that all you've got?" he rasped, a faint, stubborn grin forming. "Because I'm still standing."
For a moment—
Nothing changed.
Then—
The pressure shifted.
Not gone.
But… different.
Acknowledging.
The guardian's form flickered.
"Take it."
The world snapped back.
Ren gasped as he fell forward, catching himself just before hitting the ground.
The chamber returned.
The air rushed back into his lungs.
The crystal in front of him cracked.
A sharp, echoing sound split the silence as a smaller fragment broke free, dropping onto the stone with a dull clink.
The pulsing stopped.
Everything went still.
"…Ren?" Lira rushed to his side. "What just happened?!"
He didn't answer immediately.
His eyes were locked on the fragment.
"…It chose me," he said quietly.
Lira frowned. "Chose you for what?"
Ren slowly reached down.
This time—
No hesitation.
The moment his fingers touched the fragment—
Warmth spread through his hand.
Not violent.
Not painful.
Controlled.
His core responded instantly.
A steady pulse.
For the first time—
It didn't feel like it was breaking apart.
Ren inhaled sharply.
"…It's stabilizing."
Lira's eyes widened. "What?"
He clenched his hand slightly.
A faint glow flickered around it—
Smoother.
More controlled than before.
"…Not fixed," he said. "But… better."
Relief washed over her face.
Then quickly turned into suspicion.
"…And the downside?"
Ren paused.
The warmth in his chest deepened.
Spreading.
Slowly.
Too slowly.
Too… deliberately.
"…I don't know yet."
The fragment pulsed once more in his hand.
And deep within his chest—
Something answered.
Not his core.
Something deeper.
Ren's expression darkened slightly.
"…But I don't think this is the end of it."
The chamber remained silent.
But now—
It didn't feel empty.
It felt like something had been awakened.
