11:43 PM.
The academy was silent again.
Too silent.
Lyra stood near the dorm window wearing a dark hoodie while staring at the silver key in her hand.
316.
The numbers felt heavier than metal.
Sera stood in front of the door with crossed arms.
“I’m still against this.”
Nova sat calmly on Lyra’s desk eating stolen chocolate from the dining hall.
“I’m personally excited,” she said.
Sera looked horrified.
“You would be excited about possible murder.”
Nova shrugged.
“Life gets boring.”
Lyra slipped the key into her pocket.
“I’m only checking the tunnels.”
“That’s exactly how people die in horror movies,” Sera muttered.
Lyra exhaled slowly.
Part of her knew this was dangerous.
Actually, all of her knew.
But another part—the stronger part—needed answers.
Her mother.
Kael Mercer.
The whispers.
The messages.
Someone wanted her underground for a reason.
And tonight felt important.
Important in a bad way.
The clock on the wall ticked softly.
11:47 PM.
Nova suddenly stood.
“I’m coming with you.”
“No,” Lyra said immediately.
Nova raised an eyebrow.
“You think I’m letting you wander into creepy murder tunnels alone?”
“She said come alone.”
Nova rolled her eyes dramatically.
“And serial killers also say ‘trust me.’ Doesn’t mean you listen.”
Sera pointed at Nova.
“She actually made a good point for once.”
Lyra hesitated.
Honestly, she did not want to go alone.
But something about the message felt personal.
Like whoever waited underground expected only her.
And that thought terrified her most.
“I’ll be fine,” Lyra lied.
Sera looked unconvinced.
“You literally almost got blamed for murder twelve hours after arriving here.”
“Technically hanging,” Nova corrected.
Sera stared at her.
“You need professional help.”
A soft knock suddenly echoed against the dorm door.
Everyone froze instantly.
Three slow taps.
Knock.
Knock.
Knock.
The girls looked at each other.
Nobody moved.
Then a folded piece of paper slid slowly beneath the door.
Silence.
Nova carefully approached first and picked it up.
Her expression changed immediately.
“What?”
Nova handed the paper to Lyra silently.
A single sentence was written in black ink.
HE KNOWS YOU HAVE THE KEY.
A cold shiver moved down Lyra’s spine.
Sera backed away from the door immediately.
“Nope. Absolutely not. We’re calling the police.”
Nova checked the hallway through the small door window.
Empty.
Again.
“How does someone keep doing that?” Sera whispered.
Nobody answered.
Because nobody knew.
11:55 PM.
Five minutes until midnight.
Lyra pulled her hood up slowly.
“I’m going.”
Sera grabbed her arm instantly.
“Please be careful.”
For the first time all night, fear fully showed in Sera’s eyes.
Real fear.
Lyra softened slightly.
“I’ll come back.”
Nova snorted quietly.
“Famous last words.”
Sera threw a pillow at her.
The hallway outside felt colder than before.
Emergency lights still glowed faint red along the walls while distant thunder shook the academy windows.
Most students remained locked inside their dorms.
Only teachers and security guards moved through the halls now.
Lyra walked carefully toward the west staircase while clutching the map tightly inside her hoodie pocket.
Every sound made her nervous.
Every shadow looked suspicious.
At the bottom floor, she paused near the old library entrance.
The map showed a hidden door somewhere nearby.
But where?
She looked around slowly.
Dusty bookshelves.
Ancient portraits.
Dark wooden walls.
Nothing unusual.
Then—
A faint light flickered beneath one bookshelf.
Lyra moved closer carefully.
Hidden behind the shelf sat a small metal keypad.
Her pulse quickened.
She inserted the silver key.
Click.
The entire bookshelf shifted slowly sideways.
A dark staircase appeared behind it descending underground.
Cold air rushed upward immediately.
Lyra’s stomach twisted.
This was real.
Very real.
For one brief second, she considered turning back.
Then she remembered her mother’s photograph.
And stepped inside.
The hidden doorway closed behind her automatically.
Darkness swallowed the staircase.
Only dim yellow lights along the tunnel walls guided her downward.
The deeper she walked, the colder the air became.
Water dripped somewhere nearby.
The academy above felt impossibly far away now.
The tunnel walls looked ancient—older than the school itself.
Names were carved into the stone everywhere.
Student names.
Dates.
Messages.
HELP ME.
DON’T TRUST THEM.
SHE’S STILL HERE.
Lyra’s breathing became uneven.
Who wrote these?
Another turn appeared ahead.
Then another.
The tunnels beneath Blackthorne stretched like a maze.
Finally, she reached an old rusted door marked:
LOCKER HALL B.
Her heart pounded violently now.
Slowly, she pushed the door open.
The hallway beyond was massive.
Rows of ancient metal lockers lined both walls beneath flickering lights.
Dust covered everything.
Most locker doors hung open or broken.
But one locker stood untouched at the very end of the hall.
316.
Lyra stopped breathing for a second.
The silver numbers gleamed under the weak lights.
Unlike everything else in the tunnel…
Locker 316 looked new.
Like someone still used it.
A loud metallic bang echoed somewhere behind her.
Lyra spun around instantly.
Nothing.
Only darkness.
Her pulse raced harder.
She turned back toward the locker slowly.
Then noticed something horrifying.
The locker door was already slightly open.
A cold breeze drifted from inside.
And faintly…
Very faintly…
She heard breathing.
Someone was inside.
Lyra stepped backward instinctively.
Every survival instinct screamed at her to run.
Instead, she whispered shakily:
“Who’s there?”
Silence.
Then—
A voice answered softly from inside the locker.
“You finally came back.”
