The creature stepped fully into the light.
Stone ground against stone as its massive frame emerged from the shadows, each movement heavy enough to shake the chamber. Its body was a fusion of jagged rock and ancient bone, bound together by glowing runes that pulsed like veins of molten light.
Its eyes burned with a cold, ancient intelligence.
Not a beast.
A guardian.
Lira's grip tightened on Ren's arm. "We can't fight that…"
Ren didn't respond immediately.
His gaze was fixed on the creature.
His heart pounded—but not with fear alone.
There was something else now.
A spark.
"I don't think it's giving us a choice," he said quietly.
The guardian took another step.
The ground trembled.
Then—
It moved.
Faster than something that size had any right to be.
"MOVE!" Ren shouted, grabbing Lira and pulling her aside.
The guardian's claw slammed into the ground where they had stood, the impact sending shards of stone flying in every direction.
A shockwave blasted through the chamber.
Ren was thrown back, his body skidding across the floor.
"Ghh—!"
Pain shot through his side, but he forced himself up.
"Lira!"
"I'm okay!" she coughed from behind a fallen pillar.
"Stay there!" he ordered.
The guardian turned its glowing gaze toward him.
It had chosen its target.
"Great…" Ren muttered under his breath.
His fingers twitched.
Mana flickered faintly around them—unstable, slipping like water through cracks.
Not enough.
Not even close.
The guardian lunged.
Ren barely rolled out of the way as its claw tore through the stone floor, leaving deep gouges behind.
He scrambled to his feet, breathing hard.
Too fast.
Too strong.
If he took even one direct hit—
I'm dead.
"Think…" he muttered. "Think!"
Another attack came.
Ren ducked under the sweeping arm, feeling the rush of air as it passed inches from his head.
He stumbled forward—
Then saw it.
The runes.
They pulsed brighter just before each attack.
A pattern.
A rhythm.
Ren's eyes narrowed.
"…Got you."
The guardian struck again.
This time—
Ren moved first.
He shifted to the side just as the runes flared, narrowly avoiding the blow.
Stone shattered behind him.
A small grin tugged at his lips.
"I can read you."
"Ren!" Lira shouted. "What are you doing?!"
"Buying time!" he yelled back.
"Time for what?!"
He didn't answer.
Because he didn't know.
Not yet.
The guardian roared, clearly irritated.
It raised both arms—
The runes across its body flared violently.
"Not good…" Ren muttered.
The ground beneath him cracked.
Energy gathered.
Then—
It slammed both fists down.
The impact was devastating.
The entire chamber shook as a wave of force exploded outward.
Ren was caught in it.
"AHH—!"
His body was thrown through the air, crashing hard against a pillar before dropping to the ground.
Everything went quiet.
For a second—
He couldn't breathe.
"…Ren…"
Lira's voice sounded distant.
Faint.
Pain flooded back all at once.
His chest burned.
His vision swam.
"…Get up…" he whispered to himself.
But his body didn't move.
The guardian approached slowly.
Each step deliberate.
Certain.
It knew he was finished.
"No…" Ren forced out, his fingers digging into the ground.
"I'm not… done…"
His core pulsed.
Weak.
Cracked.
But alive.
He remembered the shard.
That moment—
When the mana stayed.
"…Just once more…"
Ren clenched his hand.
"Come on…!"
For a second—
Nothing happened.
Then—
A flicker.
Mana gathered.
Unstable.
Violent.
Pain surged through his chest as the energy forced its way through his broken core.
"GHH—!"
Cracks of light spread faintly across his skin.
But he didn't let go.
"Ren, stop!" Lira screamed. "You'll kill yourself!"
"Better than dying like this!" he shot back.
The guardian raised its arm.
Preparing the final blow.
Ren pushed himself up.
Barely standing.
Mana flickering wildly around his hand.
Uncontrolled.
Dangerous.
"Just one hit…" he muttered.
"That's all I need."
The guardian's attack came down.
Ren stepped forward.
Time seemed to slow.
The runes flared.
The claw descended.
And Ren moved.
He twisted past the attack at the last possible second—
And drove his glowing hand straight into the guardian's chest.
For a heartbeat—
Nothing happened.
Then—
The runes shattered.
A burst of energy exploded from the point of impact, cracks spreading rapidly across the guardian's body.
It let out a deep, distorted roar.
The light within it flickered violently.
Ren was thrown back again, hitting the ground hard.
This time, he didn't get up immediately.
The guardian staggered.
Its massive form trembling.
Cracks of glowing light spread across its entire body.
Then—
With a final, thunderous sound—
It collapsed.
Silence fell over the chamber.
"…Ren?"
Lira rushed to his side, dropping to her knees.
"Ren! Say something!"
He groaned softly.
"…I'm… alive…"
Relief flooded her face. "You idiot… you scared me!"
He let out a weak laugh.
"…Yeah… me too…"
His body felt like it had been torn apart.
Every breath hurt.
Every movement worse.
But his core—
It pulsed.
Faint.
Weak.
But… different.
"…I felt it again," he murmured.
Lira blinked. "Felt what?"
"Control."
He slowly lifted his hand.
A tiny spark of mana flickered.
Held.
For just a second longer than before.
Then it faded.
But this time—
Ren smiled.
"I'm getting there…"
Behind them, the shattered remains of the guardian began to glow faintly.
At its core—
Something pulsed.
Lira noticed it first.
"Ren… I think it left something behind."
Ren turned his head slowly.
Despite the pain—
His eyes sharpened.
"…Of course it did."
