The wind died the moment the ruin opened. Not faded—cut. As if something inside had decided the world outside no longer deserved to breathe. Ren felt it in his chest, a pressure that wasn't air but presence. His core throbbed in answer, a slow, painful pulse that didn't match his heartbeat.
"…You feel that?" Lira asked.
"Yeah."
Behind them, the scarred man chuckled softly. "Good. Means we're in the right place." He stepped closer, boots scraping against the stone, eyes never leaving the open ruin. "After you."
Ren didn't move. "You first."
The man's smile widened. "I would. But you've got the key."
Ren's jaw tightened. He didn't like how easily the man said it—like he'd already figured something out. Like Ren wasn't just prey anymore, but a tool.
"…Ren," Lira whispered.
"I know."
The entrance yawned wider, stone grinding against stone. A faint, low rhythm seeped out from within. Not quite a sound. Not quite silence. Something in between—like a breath that had forgotten how to stop.
Ren stepped forward.
"Ren."
"I said I know."
He didn't look back. If he did, he might hesitate. If he hesitated, the man behind them would decide for him.
The threshold swallowed the last of the light. Inside, the darkness wasn't empty—it was thick, layered like smoke that refused to move. Ren lifted his hand. Mana gathered, trembling, then steadied into a dim glow. The light didn't push the dark away. It only revealed how much of it there was.
"…This place is wrong," Lira murmured.
"Yeah."
The floor beneath them was smooth, carved, but cracked by time. Symbols crawled along the walls—faint lines etched too precisely to be natural. They pulsed weakly, like dying embers.
Ren's core answered.
A sharper pulse.
Closer now.
"Stay behind me," he said.
"You keep saying that."
"And you keep ignoring it."
"…Fair."
They moved deeper. Every step echoed too long, like the ruin was listening and repeating their presence back to them. The air smelled old—dry stone, dust… and something metallic beneath it.
Blood.
Not fresh.
Not entirely gone.
Ren slowed. "…Careful."
"I've been careful since we got here," Lira whispered.
"That's not enough."
The corridor opened into a wide chamber. Pillars—broken, leaning—formed a ring around a lowered center. At its heart stood a pedestal. And on that pedestal—
A small object.
Wrapped in black cloth.
Still.
Waiting.
"…That's it," Lira breathed.
Ren didn't answer.
Because nothing about it felt simple.
The symbols along the walls brightened slightly as they stepped closer, reacting to something unseen. Ren's core pulsed harder, pain threading through his chest.
"…It's reacting to you," Lira said.
"I noticed."
Behind them, the scarred man entered the chamber, slower this time. Careful. Even he felt it. "Go on," he said. "Don't keep it waiting."
Ren exhaled slowly.
One step.
Then another.
The air thickened with each movement, pressing against his skin. The glow in his hand flickered—then steadied. For once, the mana didn't lash out. It listened.
"…That's new," he muttered.
He reached the pedestal.
Up close, the cloth wasn't just cloth. It moved—barely—like it was breathing.
"…Ren," Lira said, voice tight.
"I know."
He reached out.
For a split second, everything went silent.
No breath.
No pulse.
No thought.
Then his fingers touched the cloth.
Cold.
Not like stone.
Like something that had never been warm.
The chamber reacted.
The symbols flared. Light shot through the cracks in the walls, racing outward like veins igniting. The air slammed down on them with crushing force.
"REN—!"
He grabbed the object.
The cloth snapped tight around it—then dissolved into black dust, revealing what lay beneath.
A shard.
Dark.
Jagged.
Not like the mana shard from before. This one drank the light around it, bending Ren's glow inward.
His core exploded with pain.
"GHH—!"
He dropped to one knee, clutching the shard as it pulsed once—twice—then answered him.
Not mana.
Something deeper.
Something older.
"…You found it," a voice whispered.
Not from the room.
From inside.
Ren's breath hitched.
"…Ren?" Lira's voice sounded far away.
The chamber shifted. The lowered center split with a grinding crack, stone folding inward as darkness poured up from below—thicker, heavier, alive.
"…You shouldn't have touched that," the scarred man said quietly. Not mocking now. Not amused.
Serious.
The ground dropped.
The pedestal sank with Ren still on it, pulling him downward.
"REN!"
Lira lunged—caught his arm—held.
For a moment, it worked.
Then the force increased.
The pull from below wasn't gravity. It was hunger.
"Let go!" Ren snapped.
"No!"
"You'll get dragged in too!"
"I'm not—!"
The stone beneath her cracked.
She felt it.
Hesitated.
For just a fraction of a second—
Ren tore his arm free.
"NO—!"
He fell.
Darkness swallowed him whole.
The chamber above slammed shut, the stone sealing like it had never opened. Silence crashed down in its wake.
Lira stood frozen, hand still outstretched.
"…Ren…"
Behind her, the scarred man watched the sealed ground, expression unreadable.
"…So that's how it works," he murmured.
Lira turned on him instantly, eyes burning. "You knew?!"
"I suspected."
"You let him—"
"He chose," the man said calmly. "Just like he chose to come here."
Lira's fists trembled. "…I'm going after him."
The man's gaze shifted to her.
"…Then you'd better be ready to die."
Below—far below—
Ren hit the ground hard.
Air slammed from his lungs as darkness swallowed everything.
For a moment, there was nothing.
No light.
No sound.
No pain.
Then—
His core pulsed.
The shard in his hand answered.
And in the darkness—
Something opened its eyes.
