The compass needle trembled again.
Arin stopped walking.
The street around him was quiet. Shops were closing. A few lanterns flickered in the evening wind. Nothing unusual.
But the compass disagreed.
The fractured needle pointed northeast and vibrated with increasing intensity.
That meant only one thing.
Spatial distortion.
Arin's expression hardened.
"Too early…"
In the previous timeline, the first detectable distortion in this district occurred eleven days later. It was small, harmless, and unnoticed.
But now the compass was reacting strongly.
Which meant the timeline was already correcting itself.
Or someone was pushing it.
Arin walked quickly through the narrow streets toward the abandoned factory district. The compass needle grew more unstable with every step.
His mind ran through possibilities.
If the distortion forms into a proto-gate, creatures could leak through.
Low probability.
But not impossible.
He reached the factory ruins.
Broken windows. Collapsed walls. Rust covering old machinery.
No one came here anymore.
Perfect place for something unnatural to appear.
The compass suddenly jerked violently.
The needle snapped toward the center of the factory yard.
Arin stepped inside.
The air felt… wrong.
Heavy.
Like the atmosphere before a storm.
But there were no clouds.
Then he saw it.
A faint ripple in the air.
Like heat distortion above fire.
Except this ripple was vertical.
A thin crack.
Barely visible.
But real.
Arin exhaled slowly.
"A proto-fracture."
That meant the world barrier was weakening earlier than expected.
He stepped closer.
The crack pulsed faintly with purple light.
Not a full gate.
Not yet.
But if left alone, it could widen.
And if it widened…
Creatures would cross.
Arin crouched beside the crack, studying its rhythm.
In the previous timeline, these early distortions were impossible to detect without specialized instruments.
The compass had worked perfectly.
Good.
Very good.
But something else bothered him.
These distortions normally appeared in isolated wilderness.
Not inside a city.
He leaned closer to inspect the fracture.
And then—
Footsteps.
Arin turned.
A girl stood at the edge of the factory yard.
White academy uniform.
Long silver hair.
Cold blue eyes.
He recognized her immediately.
Elara Thorn.
In the previous timeline, she died during a minor gate event three months before the apocalypse.
Her death barely made the news.
But later analysis showed something terrifying.
She would have awakened as an S-rank spatial mage.
One of the rarest abilities.
Her early death cost humanity a powerful asset.
And now…
She was standing five meters from a spatial fracture.
Exactly like before.
Arin closed his eyes briefly.
The timeline was repeating the same trap.
Elara looked confused.
"What are you doing here?"
Arin stood slowly.
"Leaving."
She frowned slightly.
"Then why are you staring at the air?"
Because you're about to die.
But he didn't say that.
Instead he asked calmly,
"Did you feel something strange and follow it?"
Her eyes widened slightly.
"…Yes."
Exactly the same.
In the original timeline, she sensed spatial instability and came to investigate.
Then the fracture widened.
Then a creature emerged.
Then she died.
Arin looked back at the crack.
It was pulsing faster.
They had maybe thirty seconds.
He turned back to her.
"Run."
Elara blinked.
"…What?"
"Run."
"Why?"
The crack suddenly widened half an inch.
A low, unnatural sound echoed from inside it.
Elara froze.
"What is that?"
Arin grabbed her wrist.
"RUN."
They sprinted toward the factory exit.
Behind them, the crack split open.
Reality tore like fabric.
A claw pushed through.
Black. Massive. Covered in jagged bone.
A creature forced its way out of the fracture.
A Rift Stalker.
In the previous timeline, this monster had killed three people before hunters arrived.
Arin pulled Elara behind a collapsed metal beam.
She stared at the creature in shock.
"What is that thing?!"
"A problem."
The Rift Stalker sniffed the air.
It was blind.
But it hunted by sensing movement.
Elara whispered, trembling,
"Should we fight it?"
Arin looked at her.
Then at himself.
No mana.
No weapon.
"No."
"Then what do we do?!"
Arin's mind worked rapidly.
The creature had weak eyesight.
Sensitive hearing.
Extremely aggressive.
But also territorial.
He scanned the factory yard quickly.
Old gas tanks. Loose metal sheets. Broken machinery.
Plan forming.
Arin grabbed a rusted wrench from the ground.
Elara stared at him.
"…That's your plan?"
He didn't answer.
Instead he whispered,
"When I throw this, run left."
"Why left?"
"Because it will chase right."
"How do you know that?!"
"Because predators attack noise."
Before she could argue, Arin threw the wrench across the yard.
It slammed into a metal wall with a loud clang.
The Rift Stalker reacted instantly.
It lunged toward the noise.
"NOW."
They ran left.
The creature smashed into the wall where the wrench landed.
Metal exploded.
Dust filled the air.
Elara ran beside him, breathing hard.
"That thing almost killed us!"
Arin glanced back.
The creature was already turning.
Fast.
Too fast.
They wouldn't outrun it.
Arin stopped suddenly.
Elara almost crashed into him.
"Why did you stop?!"
He pointed ahead.
A narrow alley between two factory walls.
Barely wide enough for a human.
Too narrow for the monster.
"Through there."
They squeezed into the alley just as the Rift Stalker lunged again.
Its claws scraped violently against the walls.
But it couldn't enter.
It roared in frustration.
Elara leaned against the wall, shaking.
"…What… was that?"
Arin watched the creature carefully.
"A warning."
"For what?"
"For the future."
The Rift Stalker eventually retreated toward the fracture.
Then disappeared back inside.
The crack shrank slowly until it vanished.
Silence returned.
Elara looked at Arin.
"You knew that would happen."
It wasn't a question.
Arin wiped dust from his coat.
"I predicted it."
"That wasn't prediction," she said quietly.
"That was preparation."
He didn't respond.
Elara studied him carefully.
"You're not normal."
Correct.
"Neither are you," he replied calmly.
She frowned.
"What does that mean?"
Arin looked at her directly.
"In three months, you will awaken spatial magic."
Her eyes widened.
"…That's impossible."
"Yes," he agreed.
"But it will happen."
Silence fell between them.
Far above the city, hidden in the night sky, the faint cracks shimmered again.
And somewhere deep underground…
The hooded figures watched a glowing projection.
Timeline Deviation Index: 0.011%
One of them spoke quietly.
"Someone prevented the Thorn anomaly death."
Another voice answered.
"Then the variable is confirmed."
"Find him."
Outside the factory district, Arin walked toward the city.
Elara followed silently beside him.
Neither spoke for several minutes.
Finally she said,
"You saved my life."
Arin didn't look at her.
"I corrected a mistake."
She stared at him.
"…What mistake?"
Arin's eyes moved toward the sky.
The same sky that would tear open in 132 days.
"The one the future made."
