The room didn't feel quiet. It felt empty.
Arin sat at the edge of the bed, a faintly glowing monster core turning slowly between his fingers. The weak blue light flickered across his knuckles, then dimmed again.
Not enough.
Not even close.
He closed his hand around it, then loosened his grip.
Authority missions were clean. Controlled. Predictable.
None of that made you stronger.
Arin's gaze shifted toward the window. The city stretched out into darkness, distant lights blinking like something alive beneath the surface.
"…Yeah," he muttered quietly. "Not doing that again."
The core disappeared into his coat.
A second later, he was already moving.
The outer metro district was quiet in a way that felt abandoned rather than peaceful.
Streetlights buzzed faintly over cracked pavement. Rusted rails cut through empty maintenance zones no one cared about anymore.
Perfect.
Arin slowed as Echo Sense spread beneath the surface of the world.
It responded almost instantly.
A distortion.
Small. Unstable. Close.
He stopped near a broken fence surrounding an old maintenance yard and watched the air between two concrete pillars ripple slightly.
No Authority.
No hunters.
Good.
Arin stepped over the fence and approached without urgency, eyes fixed on the distortion as it pulsed unevenly.
The air warped again.
Like something breathing on the wrong side of reality.
His fingers brushed the dagger at his side.
"…Let's see if you're worth the trouble."
He pulled the scarf up over his face.
And stepped through.
Reality twisted.
The Gate swallowed him whole.
Inside, the world resembled a metro tunnel—but broken in ways that didn't make sense.
Rail lines curved upward along the walls.
Chunks of concrete floated in midair.
Fragments of old train cars hung suspended like debris caught in invisible currents.
Arin landed lightly and let Echo Sense expand.
Multiple signatures responded immediately.
Fast. Erratic. Hunting.
"…Figures."
A Rail Crawler dropped from above, claws aimed for his throat.
Arin didn't move right away.
He let it come close enough to feel the air shift—
Then stepped aside at the last possible moment.
The creature missed.
Arin's dagger slid upward beneath its jaw.
Abby's Seal activated instantly.
Gravity collapsed.
The monster slammed into the ground with a heavy crack, its body folding unnaturally under the force.
Arin stepped past it without looking back.
Another crawler rushed him from the side.
This one was faster.
More aggressive.
Arin stepped into the attack instead of away from it.
Claws scraped across his coat.
His blade slipped between the armor plates along its ribs.
A controlled pulse of gravity followed.
The creature dropped instantly.
Two more closed in.
"…You're persistent."
The first leapt.
Arin caught it mid-air and drove the blade straight through its skull.
At the same time, gravity twisted sharply behind him—
The second creature was ripped off its path and slammed into the tunnel wall with a violent impact.
Arin turned and finished it cleanly.
Silence returned.
For a moment.
Then Echo Sense pulsed again.
Heavier this time.
Slower.
"…There you are."
The tunnel opened into a collapsed maintenance chamber.
Broken rails.
Hanging steel beams.
Water dripping somewhere deep in the dark.
Then the ground shifted.
A low grinding sound rolled through the space.
Something massive pushed upward through the debris.
The Boneback Brute emerged.
Its armored body dragged itself into the open, bone plating thick and uneven, weight alone distorting the air around it.
Arin studied it for a second.
"…You're in the wrong place."
The brute didn't hesitate.
It charged.
Fast.
Too fast for its size.
Its first strike tore through the wall beside him, concrete exploding outward.
Arin moved just in time.
The force brushed past him.
He stepped in and struck—
The blade sparked uselessly against bone armor.
"…Yeah," Arin muttered, shifting his stance. "That was optimistic."
The brute turned sharply and attacked again.
This time the hit connected.
The impact threw Arin across the chamber.
He hit the ground hard, rolled, then pushed himself up, breath steady despite the pain.
"…Alright."
He adjusted his grip on the dagger.
"…You hit harder than expected."
The brute roared and charged again.
Arin didn't retreat.
Abby's Seal expanded.
The air tightened.
Gravity twisted violently beneath the creature's legs, dragging its own mass against it.
The brute's movement faltered.
Just enough.
Arin stepped in instantly.
No hesitation.
The dagger drove upward beneath its jaw.
Gravity collapsed inward.
The sound was deep.
Heavy.
Bone folding under pressure.
The creature slammed into the ground.
And stayed there.
Still.
Dead.
Arin stood over it briefly, watching.
Then crouched and pulled the core free.
"…Better."
His eyes shifted toward something else nearby.
A metallic fragment, half-buried in debris.
He pulled it free and turned it slightly.
Cracked surface.
Faint energy flickering inside.
Unstable.
Incomplete.
"…What's that."
He exhaled quietly.
"…Hope it sells."
The relic disappeared into his coat.
When Arin stepped out of the Gate, the air felt real again.
Cold.
Sharp.
Clean.
He pulled the scarf down and lit a cigarette.
The lighter sparked once.
Flame caught.
A slow inhale.
Then exhale.
Silence.
For a second.
Then Echo Sense shifted.
Someone was following him.
Arin didn't react immediately.
He took one last drag.
Dropped the cigarette.
Crushed it under his heel.
The scarf came back up.
He moved.
Not toward the main road.
Not toward the black market.
Into narrow alleys instead.
A detour.
Footsteps followed.
Steady.
Controlled.
Arin stopped.
Still facing away.
"I know you're there."
Footsteps echoed softly.
Evelyn Cross stepped into the dim light of the alley, her eyes locking onto him immediately.
"You're harder to follow than I expected," Evelyn said calmly.
Arin tilted his head slightly.
"Maybe you're not as good as you think."
Evelyn ignored the jab and stepped closer.
"You came out of that Gate."
Arin turned halfway toward her.
"Most people do."
Evelyn's gaze sharpened.
"You went in alone. And you stayed long enough to deal with something that shouldn't have been there."
Arin leaned one shoulder against the wall.
"Sounds like you already decided what happened."
Evelyn didn't blink.
"I saw you step in front of that Tyrant."
Arin met her gaze.
"And you're still standing."
Evelyn's tone hardened.
"That wasn't the point."
Arin shrugged slightly.
"It usually is."
Evelyn closed the distance between them.
"You could have walked away."
Arin answered without hesitation.
"I did."
Evelyn frowned.
"You came back."
Arin glanced briefly past her, uninterested.
"Bad timing."
"That's not an explanation."
"It's enough."
Evelyn held his gaze.
"Why did you help me?"
Arin looked at her for a moment.
Then answered quietly.
"You're still alive."
Evelyn's voice dropped slightly.
"That's not a reason."
Arin pushed off the wall and walked past her.
"I didn't ask you to understand it."
Evelyn turned after him.
"You're just going to disappear again?"
Arin didn't stop.
"That's usually how this goes."
Evelyn spoke again.
"Authority is already looking for you."
Arin replied without turning.
"I assumed."
Evelyn studied him carefully.
"You move like you don't want to be seen… but you don't exactly hide either."
Arin tilted his head slightly.
"That sounds like a problem for them."
Evelyn spoke one last time.
"You're not what people say."
Arin slowed just slightly.
Then answered:
"People say whatever helps them sleep."
He kept walking.
"Try not to die next time."
Evelyn remained in the alley.
Watching him disappear.
Her fingers tightened slightly at her side.
"I'll find out who you are."
Her voice was calm.
Certain.
"…Sooner or later."
