Ethan spent the next three days trying to convince himself not to go.
It didn't work.
The hidden staircase remained stuck in his mind.
Every time he sat in class, he thought about it.
Every time he closed his eyes, he saw it.
Every time he opened the pocket watch, the same word appeared in his thoughts.
Below.
The message never changed.
The watch never explained.
The system remained equally unhelpful.
And somehow that made everything worse.
---
Thursday evening arrived.
Rain covered the city.
Water streamed down windows.
The streets glistened beneath streetlights.
It was the kind of weather that made most people want to stay indoors.
Ethan should have been one of those people.
Instead, he was putting batteries into his flashlight.
Again.
---
His preparations looked slightly less pathetic this time.
Flashlight.
Power bank.
Water bottle.
Notebook.
Pocket knife.
First aid kit.
Extra batteries.
Phone.
---
Lily walked into his room.
Looked at the equipment.
Then looked at him.
Then looked at the equipment again.
---
"You planning a murder?"
---
"No."
---
"You sure?"
---
"Pretty sure."
---
She crossed her arms.
---
"You're being weird again."
---
"That's becoming a common complaint."
---
"I'm serious."
---
Ethan knew she was.
That made lying harder.
---
"I'm just checking something."
---
"At eleven at night?"
---
"...Maybe."
---
Lily narrowed her eyes.
The expression reminded Ethan of a detective who already knew the answer.
---
"You're going back to the station."
---
Ethan froze.
---
Silence.
---
"That wasn't a question."
---
"Damn."
---
"Language."
---
"You literally swear more than I do."
---
"That's different."
---
"It absolutely isn't."
---
For several seconds neither spoke.
Then Lily sighed.
---
"I don't know what's going on."
---
Her voice had lost its usual teasing tone.
---
"But whatever it is..."
She hesitated.
"...be careful."
---
Something tightened inside Ethan's chest.
---
"Yeah."
---
Lily nodded once.
Then left.
Closing the door behind her.
---
For a long moment, Ethan stared at the closed door.
The guilt lingered longer than expected.
---
Then he grabbed his backpack.
And left.
---
The station was nearly empty.
Rain had driven most people home.
Only a handful of passengers remained.
The announcements sounded strangely distant.
As though the building itself had become quieter.
---
Ethan made his way toward Platform Three.
His heart beat faster with every step.
Not from excitement.
From common sense.
Common sense was screaming at him to leave.
---
The abandoned platform waited in darkness.
Silent.
Unmoving.
The rusted gate remained locked.
Just as it should.
---
Ethan pulled out the pocket watch.
---
Click.
---
The lid opened.
The map appeared immediately.
The red mark pulsed.
Slowly.
Patiently.
Directly beneath the platform.
---
He concentrated.
Mana flowed through his body.
A familiar warmth spread through his hands.
---
Mana Thread.
---
A faint blue strand appeared between his fingers.
Thin.
Fragile.
Barely visible.
---
The moment he touched the gate with it—
Reality flickered.
---
The hidden staircase appeared.
---
His breath caught.
There it was.
Exactly where he had seen it before.
Half hidden behind concrete.
Descending into darkness.
---
And this time it remained visible.
---
Mana: 8/10
---
So maintaining the spell cost mana.
Good to know.
Bad for survival.
---
Ethan stepped forward.
The staircase didn't vanish.
---
One step.
Two.
Three.
---
He passed through the illusion covering the entrance.
Cold air rushed over him immediately.
---
The temperature dropped several degrees.
---
The sounds of the station faded.
---
Behind him, trains still moved.
People still walked.
Announcements still played.
Yet all of it felt distant.
Muted.
Like listening through thick walls.
---
The staircase spiraled downward.
Far deeper than it should.
Far deeper than any station basement.
---
The concrete looked ancient.
Cracks covered every wall.
Dust coated every surface.
---
Nobody had been here in years.
Maybe decades.
---
Ethan continued downward.
Slowly.
Carefully.
Every nerve in his body remained tense.
---
Five minutes passed.
Then ten.
---
The staircase still hadn't ended.
---
"How deep is this place?"
---
No answer came.
---
Only silence.
---
Then he saw something.
---
Writing.
---
Words carved into the wall.
---
Ethan raised his flashlight.
The beam illuminated dozens of messages.
Hundreds.
Maybe thousands.
---
Some were faded.
Others looked recent.
---
The nearest one read:
Don't go further.
---
A second message sat beneath it.
---
The voices lie.
---
A third.
---
The door must remain closed.
---
Ethan swallowed.
---
The deeper he looked, the worse the messages became.
---
It's listening.
---
Turn back.
---
We're sorry.
---
Seal it again.
---
His pulse quickened.
---
These weren't random graffiti.
The words felt desperate.
Terrified.
As if written by people who genuinely believed them.
---
The staircase finally ended.
---
Ethan stepped into a massive underground chamber.
And froze.
---
The room was enormous.
Large enough to fit several buildings.
Ancient stone pillars stretched upward into darkness.
The ceiling disappeared beyond the reach of his flashlight.
---
This place should not exist.
---
Not beneath a train station.
Not beneath a city.
Not anywhere.
---
His light swept across the chamber.
Then stopped.
---
A door stood at the center.
---
Not a normal door.
---
A gigantic stone structure over twenty feet tall.
Covered in symbols.
Chains.
And thousands of strange markings.
---
The Hidden Door.
---
For several seconds, Ethan forgot to breathe.
---
The thing felt wrong.
Not evil.
Not hostile.
Simply wrong.
Like something that didn't belong in reality.
---
The pocket watch suddenly vibrated.
Violently.
---
The red mark disappeared from the map.
---
It had reached its destination.
---
A notification appeared.
---
[Quest Complete]
Find the Hidden Door
---
Reward Available
---
Ethan barely noticed.
His attention remained fixed on the massive stone door.
---
Then he heard it.
---
A whisper.
---
Soft.
Almost impossible to hear.
---
Coming from the other side.
---
His blood ran cold.
---
The whisper came again.
---
Then another.
---
And another.
---
Hundreds.
Thousands.
---
Countless voices speaking at once.
---
He couldn't understand the words.
Yet somehow he understood the meaning.
---
They wanted out.
---
A sharp pain exploded behind his eyes.
---
The voices became louder.
---
His vision blurred.
---
A new notification appeared.
---
[Warning]
Mental Influence Detected
---
Warning
---
Warning
---
Warning
---
The system messages flashed repeatedly.
---
Ethan stumbled backward.
His breathing became ragged.
---
The whispers suddenly stopped.
---
Complete silence returned.
---
For several terrifying seconds, nothing happened.
---
Then a loud crack echoed through the chamber.
---
Ethan's eyes widened.
---
One of the chains wrapped around the door had broken.
---
Slowly.
Very slowly.
A dark substance leaked from the crack.
Like black smoke.
Like liquid shadow.
Like something alive.
---
And somewhere beyond the door...
Something laughed.
---
A deep.
Ancient.
Inhuman laugh.
---
The sound echoed through the underground chamber.
---
And for the first time since becoming a sorcerer...
Ethan truly understood why the ghost had been afraid.
