The first bell rang before sunrise.
Its deep, metallic toll rolled across Shinokuni-01 like distant thunder, shaking rooftops and rattling windowpanes. It was a sound every citizen had grown up hearing—a sound older than the city itself. One bell meant dawn. Two meant the Watch had changed. Three…
Three meant danger.
Today, there was only one.
The city slowly awoke.
Lanterns hanging above narrow streets flickered out one by one as the eastern sky turned from black to deep violet. Bakers unlocked their doors, letting the scent of fresh bread drift into the morning air. Merchants arranged fruits, fabrics, and handmade tools across wooden stalls while children chased one another through alleyways before their parents could drag them back inside.
To most people, it was just another day.
To the Watchmen standing atop the Wall, every sunrise was another victory.
The Wall of Shinokuni-01 towered over everything.
It wasn't merely a wall—it was a mountain carved by human hands.
Built from black stone reinforced with forgotten alloys, its surface stretched nearly a kilometer into the sky. Massive watchtowers stood along its length every few hundred meters, each equipped with ancient searchlights and heavy ballistae designed to repel anything foolish enough to approach.
No one alive had seen the Wall being built.
Some claimed the first survivors raised it after the Great Experiment.
Others believed the Celestials themselves had gifted it to humanity.
The truth had been buried long ago.
Brook Smith leaned against the cold stone railing of Watchtower Seven, his eyes fixed beyond the Wall.
Morning fog blanketed the wilderness outside like a silver ocean.
Hidden beneath it lay forests that had swallowed entire cities, broken highways disappearing beneath roots thicker than houses, and the forgotten skeletons of a civilization that no one was allowed to discuss in detail.
Most Watchmen hated staring into the fog.
Brook couldn't stop.
"You'll wear a hole through the horizon if you keep looking."
Brook smiled faintly without turning around.
"I've been trying for years."
Heavy footsteps echoed against the tower's stone floor.
Crowley emerged from the stairwell carrying two steaming tin cups.
His brown military coat hung loosely over broad shoulders, and a weathered longsword rested comfortably against his back. A scar ran across the left side of his jaw—a souvenir from an encounter he refused to talk about.
He held out one of the cups.
"Coffee."
Brook accepted it with a grateful nod.
"I thought they ran out."
"They did."
Brook raised an eyebrow.
Crowley grinned.
"I convinced the kitchen staff otherwise."
"You stole it."
"I prefer the term 'strategically relocated.'"
Brook laughed quietly.
"You always have an excuse."
"And you've never complained while drinking it."
Brook lifted the cup toward him.
"Fair point."
For a while, neither of them spoke.
The silence wasn't awkward.
It never was.
The wind carried the scent of pine trees from beyond the Wall, mixed with the familiar smell of oil, steel, and stone from the fortress behind them.
Crowley finally broke the silence.
"You had the dream again."
Brook's smile faded.
"…Yeah."
"You want to talk about it?"
"It never changes."
Crowley leaned against the battlements.
"Tell me anyway."
Brook stared into the endless fog.
"I was little again."
His voice was calm.
Too calm.
"We were living near Laboratory Nine."
Crowley listened without interrupting.
"My mother kept telling me she'd be back before dinner."
He paused.
"My father laughed because she always underestimated how long work took."
A faint smile crossed Brook's face.
"He promised we'd go fishing when they got home."
The smile disappeared as quickly as it came.
"They never did."
Silence.
The Great Experiment had taken millions of lives.
For Brook, it had taken only two.
And somehow…
That hurt more.
Official records listed Dr. Adrian Smith and Dr. Elena Smith among the confirmed dead.
Brook had read those records countless times.
He had also burned every copy he could find.
"They're alive," he whispered.
Crowley sighed.
"You've been saying that since we met."
"I'll stop saying it when someone proves me wrong."
"They already did."
"They proved bodies were never found."
Crowley couldn't argue with that.
No remains.
No funeral.
No grave.
Only names scratched onto a memorial wall that Brook refused to visit.
Below them, the city grew louder.
The morning market had opened.
Workers headed toward factories powered by massive steam generators.
Watchmen changed shifts atop the Wall.
Blacksmiths hammered glowing steel while schoolchildren marched toward classrooms carrying worn leather satchels.
Life continued.
It always did.
Crowley watched the city below.
"You ever think about leaving?"
Brook answered immediately.
"Every day."
Crowley chuckled.
"I knew you'd say that."
"I wasn't joking."
"I know."
Brook took another sip of coffee.
"I don't belong here."
Crowley folded his arms.
"You've got a roof over your head."
"A tiny apartment."
"You've got food."
"Usually."
"You've got a job."
"That barely pays."
"You've got friends."
Brook looked sideways.
"I've got one."
Crowley pretended to look offended.
"Only one?"
"You scare everyone else away."
"I call that quality control."
Brook laughed again.
It was a genuine laugh this time.
One of the younger Watchmen approached from the opposite end of the tower.
"Morning, Captain Crowley."
Crowley nodded.
"Morning."
The recruit turned to Brook.
"You staying after your shift again?"
Brook shrugged.
"I like the view."
The young man glanced uneasily toward the wilderness beyond the Wall.
"I don't."
He quickly continued on his way.
Crowley watched him leave.
"First year."
Brook nodded.
"He still thinks monsters are the scariest thing outside."
"And you don't?"
Brook's eyes never left the fog.
"No."
"What do you think is scarier?"
Brook answered so quietly that the wind almost carried the words away.
"The truth."
Crowley studied him for a long moment.
"You're going to get yourself into trouble one day."
Brook smiled.
"I usually do."
Far below, another bell echoed through Shinokuni-01.
Two bells.
The morning shift had officially begun.
The city was alive.
The Wall stood unbroken.
Beyond it…
The mist remained perfectly still.
As though something within it was watching.
Waiting.
And somewhere deep beyond the endless forest…
Something opened its eyes.
Brook hated standing still.
The moment the second bell faded into silence, Watchtower Seven came alive with movement. Fresh guards climbed the spiral staircase to relieve the night shift, while exhausted Watchmen exchanged reports before disappearing down the stone steps toward the barracks.
Captain Elias Mercer, the officer overseeing the northern wall, walked past carrying a leather clipboard.
"Anything unusual?" he asked.
Crowley answered first.
"Same fog. Same silence."
Mercer looked toward Brook.
"And you?"
Brook hesitated.
"…Nothing worth reporting."
The captain studied him for a second longer before nodding.
"Good."
He continued down the wall.
Crowley waited until Mercer was out of earshot before speaking.
"You almost said something."
Brook leaned against the battlement.
"I was thinking."
"Dangerous habit."
Brook smirked.
"Do you ever wonder why the fog never reaches the Wall?"
Crowley blinked.
"What?"
"The fog." Brook gestured beyond the massive barrier. "Look at it."
Crowley looked.
It stretched endlessly across the ruined wilderness like a pale ocean.
"But it never crosses."
"So?"
"So why?"
Crowley shrugged.
"Wind."
"There isn't any."
"There is."
Brook held up the loose sleeve of his coat. The fabric fluttered gently behind him.
"The wind's blowing toward the wilderness."
Crowley frowned.
Brook continued.
"If the wind's moving that direction… why has the fog stayed in the exact same place for as long as anyone remembers?"
Crowley looked again.
For the first time…
He noticed it.
The fog wasn't drifting.
It wasn't rolling.
It wasn't thinning.
It simply…
Stayed.
"…That's unsettling."
Brook gave a small nod.
"I know."
A loud whistle echoed from below.
Training had begun.
Hundreds of recruits marched into the enormous courtyard inside the Wall, wooden practice swords clashing beneath the watchful eyes of instructors.
Every child in Shinokuni-01 dreamed of becoming one of two things.
A Watchman…
Or a Royal Knight.
Both careers promised honor.
Neither promised survival.
Brook watched a line of children run obstacle courses with determined expressions.
One little boy couldn't have been older than eight.
He stumbled over a wooden barrier and landed face-first in the dirt.
Several recruits laughed.
The instructor barked for silence.
The boy climbed back to his feet.
Covered in mud.
Trying not to cry.
Brook smiled.
"He'll make it."
Crowley glanced at him.
"How can you tell?"
"He stood back up before anyone helped him."
Crowley chuckled.
"You've always judged people strangely."
"It's more accurate."
The sound of wheels rattling over stone drew their attention to the street below.
Supply wagons rolled toward the northern gate under heavy guard.
Crates stamped with the royal crest were carefully unloaded by laborers.
Food.
Medicine.
Weapons.
Everything entering or leaving the Wall was recorded.
Nothing escaped the King's eyes.
Or so the people believed.
Brook watched several workers struggle to carry a long wooden crate toward the military warehouse.
The side of the crate split open against the corner of a building.
Books spilled across the street.
Old books.
The workers immediately panicked.
"Hurry!"
"Pick them up!"
"Don't damage them!"
A supervisor rushed over, his face pale.
"What happened?"
"The crate broke, sir!"
He looked around nervously before shouting,
"Cover them!"
Workers threw thick canvas sheets over the scattered books before nearby civilians could get close.
Brook narrowed his eyes.
"Books?"
Crowley nodded.
"The Archives."
"They're treating them like weapons."
"They practically are."
Brook looked at him.
Crowley lowered his voice.
"You know how history is here."
Brook did.
Every school used government-approved textbooks.
Every public library carried the same editions.
Every lesson about the Great Experiment ended with the same sentence.
The past is best left buried.
Brook had never liked that sentence.
Not because it sounded suspicious.
Because it sounded afraid.
"Ever been inside the Royal Archives?" he asked.
Crowley laughed.
"You trying to get us executed?"
"I'm serious."
"So am I."
Crowley leaned closer.
"My father worked security there."
Brook's eyebrows lifted.
"You never told me that."
"He wasn't allowed to."
"What did he say?"
Crowley's expression changed.
"He said there are rooms underground."
Brook listened carefully.
"Thousands of books."
Brook nodded.
"I know that."
Crowley shook his head.
"No…"
He looked around to make sure nobody was close enough to hear.
"He said some of the books…"
"…aren't written in any language humans can read."
Brook stared at him.
"What?"
"My father only saw one."
"He said the pages moved."
Brook frowned.
"Moved?"
"The letters."
Crowley rubbed the back of his neck.
"I always assumed he was joking."
Brook wasn't smiling.
"What happened to him?"
Crowley's gaze drifted toward the city below.
"He disappeared during a transfer."
Brook froze.
"Disappeared?"
"The official report said Abominations attacked the convoy."
"And you don't believe it."
Crowley gave a humorless smile.
"I've stood on this Wall for twelve years."
"I've seen what Abominations do."
"They don't steal books."
Before Brook could answer, the great bronze clock tower in the center of Shinokuni-01 chimed.
Nine times.
The marketplace erupted into its busiest hour.
Street musicians filled the air with lively melodies while vendors called out today's prices.
Children laughed.
Mothers bargained.
Blacksmiths hammered steel.
From this height, the city looked peaceful.
Safe.
Alive.
Brook wondered how many of them had ever questioned the history they had been taught.
How many had simply accepted the world exactly as it was.
He wasn't sure which answer frightened him more.
Then…
A flock of birds burst from the forest beyond the Wall.
Hundreds of them.
All at once.
Brook's eyes narrowed.
Birds didn't flee without a reason.
Something had disturbed them.
Far beyond the sea of mist…
A deep, distant sound echoed across the wilderness.
Not a roar.
Not thunder.
Something…
Far older.
Crowley looked toward the horizon.
"…Did you hear that?"
Brook didn't answer.
He was already staring into the fog.
And for the briefest moment…
He could have sworn…
Something enormous moved beneath it.
For several long seconds, neither of them spoke.
The fog settled once more, smooth and silent, as if nothing had disturbed it at all.
Crowley finally exhaled.
"…Tell me you saw that."
Brook never took his eyes off the wilderness.
"I did."
"What was it?"
"I don't know."
Crowley frowned.
"You've never said those words before."
Brook gave the smallest shrug.
"There's a first time for everything."
The older man rested both hands on the battlement.
"You think it's an Abomination?"
Brook slowly shook his head.
"No."
"You answered pretty quickly."
"Because Abominations hunt."
Crowley waited.
"They don't hide."
A horn suddenly echoed along the Wall.
Three short blasts.
One long.
Watchmen immediately sprang into motion.
Archers rushed to their assigned positions while crews loaded enormous ballistae overlooking the wilderness.
The reaction was so practiced that no one shouted.
Everyone simply moved.
Captain Mercer stormed back onto the tower.
"Report!"
Crowley saluted.
"Unidentified movement in Sector Seven."
"You confirmed visual?"
"No, sir."
Mercer looked at Brook.
"You?"
"I saw movement beneath the fog."
"Size?"
Brook hesitated.
"…Large."
"How large?"
"I don't know."
Mercer's jaw tightened.
"I need better than that."
Brook looked toward the horizon.
"It wasn't walking."
"What?"
"It was…" Brook searched for the right word.
"…gliding."
Mercer stared at him.
Nothing in the field manuals glided.
Nothing.
The captain grabbed a brass speaking tube fixed to the stone wall.
"Sector Seven to Central Command."
Static crackled.
Then a voice answered.
"Central Command receiving."
"Possible unidentified movement beyond visual range."
"Classification?"
Mercer looked toward Brook again.
Brook simply shook his head.
"Unknown."
Silence.
Even through the speaking tube, the operator sounded uneasy.
"…Repeat."
"Unknown."
That single word carried more weight than any alarm.
Every creature outside the Wall had a classification.
Every threat had a protocol.
There was no protocol for unknown.
Mercer slowly lowered the tube.
"No reports leave this tower until Headquarters investigates."
"Understood?"
Everyone answered at once.
"Yes, sir."
The captain descended the stairs with hurried steps.
Within moments the tower was quiet again.
Crowley folded his arms.
"I've never heard Mercer sound nervous."
Brook nodded absentmindedly.
"He wasn't nervous."
"What was he?"
"He was surprised."
Crowley looked confused.
"Difference?"
Brook finally turned away from the wilderness.
"Nervous people expect something bad."
"Surprised people realize they don't understand what's happening."
Crowley hated when Brook said things like that.
Mostly because they usually turned out to be true.
The remainder of the morning passed without incident.
At least…
That's what the official reports would say.
Brook continued his patrol along the Wall, greeting familiar faces as he went.
Old Mason, the Wall engineer, was already inspecting cracks between the ancient stones with a brass hammer nearly as old as he was.
The elderly man barely looked up.
"Morning, Brook."
"Morning."
"You keeping my Wall safe?"
Brook smiled.
"I thought it belonged to everyone."
Mason snorted.
"Everyone lives behind it."
He tapped the stone affectionately.
"I live for it."
Brook knelt beside him.
"Find anything?"
"The same thing I find every week."
"The Wall refuses to age."
Brook ran a hand across the black stone.
It felt impossibly smooth.
No cracks.
No erosion.
No weathering.
A hundred years of storms should have scarred it.
Instead…
It looked almost new.
"Doesn't that bother you?" Brook asked.
Mason frowned.
"What?"
"Nothing lasts forever."
"The Wall does."
"How?"
The old engineer shrugged.
"Because it has to."
Brook wasn't satisfied with the answer.
He rarely was.
Near the eastern watch platform, several recruits struggled to haul fresh arrows into storage.
One of them accidentally dropped a bundle.
Hundreds of arrows scattered across the walkway.
Before anyone could react, Brook stepped forward.
In one smooth motion, he caught a rolling arrow with his boot, grabbed another from midair, and snatched a third before it disappeared through a drainage gap in the stone.
The recruits stared.
"How did you—"
Brook handed the arrows back.
"Practice."
One young woman whispered to another.
"He's faster than Captain Crowley."
Crowley, who had just walked into earshot, placed a hand dramatically over his chest.
"I heard that."
The recruits froze.
Crowley sighed.
"You're supposed to whisper after I leave."
Laughter spread across the platform.
Even Brook chuckled.
For a little while…
The morning felt normal again.
As noon approached, the fog finally began to thin.
Not much.
Just enough for sunlight to reach the broken landscape beyond.
Ruined highways emerged from beneath tangled vines.
The skeleton of a collapsed suspension bridge stretched across the horizon.
The remains of towering buildings stood like gravestones against the pale sky.
Brook rested both hands on the railing.
He had seen these ruins thousands of times.
Yet every day…
He searched them for something.
Anything.
A sign.
A light.
Movement.
Proof that the world outside still held answers.
Crowley stepped beside him.
"You know what I think?"
Brook smiled faintly.
"You usually tell me before I ask."
"I think you're looking in the wrong place."
Brook glanced sideways.
"What do you mean?"
"If your parents survived…"
Crowley looked back toward the city behind them.
"…maybe the answers aren't outside."
Brook frowned.
"…Maybe they're inside these Walls."
The words lingered between them.
For the first time in years…
Brook considered the possibility that his search had always been pointed in the wrong direction.
Before he could respond—
A sound drifted across the wilderness.
Soft.
Almost impossible to hear.
Crowley's expression froze.
"…Brook."
"I hear it."
The sound came again.
Not a roar.
Not the howl of a Beast.
It sounded…
Like someone crying.
A man's voice.
Weak.
Broken.
Calling from somewhere beyond the endless sea of mist.
Brook's heartbeat quickened.
No human had survived outside the Wall alone.
Not for a hundred years.
Yet the voice came again.
Clearer this time.
"…Help…"
Brook and Crowley looked at one another.
Neither of them spoke.
Because both of them had heard the same impossible word.
