The air changed first.
It wasn't colder.It wasn't heavier.
It was… still.
Gōrin felt it before anyone else.
He slowed his pace instinctively, one hand lifting slightly—signal silencieux. Ren, Saeko et Iori stopped without question, the four of them frozen at the edge of what used to be an industrial district.
Before them rose a structure that did not belong.
Everything around it had decayed.
Concrete crumbled. Steel beams sagged. Rust devoured fences and machinery alike, turning the district into a graveyard of forgotten labor.
But the building at the center—
It stood untouched.
A massive forge complex, half-buried in the ground, its exterior walls dark and smooth, unmarred by time or corrosion. No moss. No cracks. No graffiti.
As if the world had tried to erase it.
And failed.
Ren let out a low whistle.
— …That's not normal.
Saeko's eyes narrowed.
— Nothing around here should look that clean.
Iori adjusted his device, frowning as the screen flickered violently.
— Scans are useless.— No heat signature. No decay patterns.— It's like the structure rejects environmental data.
Gōrin's scar pulsed once.
Hard.
He clenched his jaw.
— Yeah…— That's his work.
Ren looked at him.
— You're sure?
Gōrin didn't answer right away.
His gaze was locked on the sealed entrance—two massive doors fused shut, covered in faint geometric engravings almost invisible unless the light hit them just right.
— I've seen this kind of craftsmanship once before, he said finally.— And it nearly got us all killed.
Saeko stepped closer to the door, blades ready.
— Traps?
— Always, Gōrin replied.— The kind you don't see until they've decided you're not welcome.
Iori raised a hand.
— Then we don't brute-force it.
Ren cracked his neck.
— Shame.
They spread out instinctively, years of unspoken coordination guiding their movements.
As they approached the forge, the ground beneath their feet changed texture—smooth stone replacing broken asphalt. The transition was too sudden to be natural.
Saeko stopped.
— Feel that?
Ren stomped lightly.
— Yeah.— Like stepping onto a different rule set.
Iori's device buzzed sharply.
— Local spatial parameters just shifted.— Not a Confluence… something more contained.
Gōrin's scar burned.
— He didn't just build weapons here.— He built boundaries.
Ren frowned.
— To keep people out?
Gōrin shook his head.
— To keep things in.
The doors loomed before them now.
Up close, the engravings were clearer—interlocking symbols etched with surgical precision. They weren't decorative.
They were instructions.
— Language, Iori murmured.— But not Shiori's dialect.
Saeko glanced at him.
— Can you read it?
Iori swallowed.
— …Enough to know we shouldn't touch it wrong.
Ren grinned.
— That's reassuring.
Before anyone could respond, the engravings pulsed faintly.
Not with light.
With pressure.
Saeko stiffened instantly.
— Something's reacting.
The ground behind them shifted.
Ren turned—
— CONTACT!
The concrete split as figures emerged—not crawling, not climbing, but unfolding from the ground itself. Humanoid shapes made of layered metal and stone, joints clicking with unnatural precision.
Constructs.
Their eyes ignited with pale blue light.
— Defensive units, Iori shouted.— Automated!
The first construct lunged.
Saeko moved.
She vanished in a blur, blades flashing as she carved across its neck joint. Sparks flew—but the construct didn't fall. It twisted unnaturally and slammed its elbow into her ribs.
Saeko skidded back, coughing.
— Not human.— No pain response!
Ren charged head-on.
— Then I don't need to hold back!
He slammed his fist into the construct's torso. The impact shattered stone plating—but the thing grabbed his arm mid-strike, grip crushing.
Ren snarled.
— Oh, you're strong?
Gōrin crashed into it from the side, his fist exploding into its head. The construct's skull caved inward, light flickering violently before it collapsed.
— Focus joints! Gōrin barked.— They're not built to recover once alignment breaks!
More constructs emerged—four, then six—forming a loose perimeter.
Iori moved fast, fingers flying across his device.
— They're responding to proximity, not aggression.— The forge is deciding whether we're intruders.
Saeko wiped blood from her mouth.
— Then let's convince it otherwise.
She darted forward again, this time aiming low—slicing through knee joints, destabilizing the constructs before Ren smashed them apart with brutal follow-up blows.
Gōrin tore through two at once, sheer force and experience overwhelming their mechanical precision.
But more kept coming.
— They're endless, Ren growled.— This is a test, isn't it?
Iori's eyes widened.
— Yes.— And we're failing it.
The engravings on the doors flared again, pressure intensifying.
Gōrin froze.
— Stop attacking!
Everyone hesitated.
— What?!
— STOP! Gōrin roared.
Reluctantly, they pulled back.
The constructs halted mid-motion.
Their lights dimmed slightly.
The pressure eased.
Iori breathed hard.
— …They weren't meant to be destroyed.
Saeko frowned.
— Then what?
Gōrin stepped forward alone, hands open.
— We weren't here to steal.— Or to break what he made.
His voice echoed strangely across the stone courtyard.
— We came because the past won't stay buried.
The forge did not respond.
Then—
The ground vibrated once.
Low.
Deep.
Like a massive mechanism acknowledging a statement.
The constructs stepped aside.
The doors trembled.
Slowly, impossibly, they separated with a sound like metal remembering how to breathe.
Darkness waited beyond.
Ren exhaled.
— …I hate places like this.
Iori stared into the opening, dread and awe mixing in his eyes.
— Whatever's inside…— It wasn't meant to be found yet.
Gōrin clenched his fists.
— Then we're late.
They stepped inside.
The doors sealed behind them.
And far away, unknown to them, something deep within the forge shifted—not awake…
but no longer asleep.
