"Books have longer memories than kings."

That was the first lesson Kai Aldren ever learned.

Not from school.

Not from the System.

But from his grandmother, whose wrinkled hands treated every dusty book as though it were a sleeping child.

Even now, those words lingered in Kai's mind as he climbed the narrow wooden ladder inside the Aldren Library, balancing three oversized books against his chest while morning sunlight poured through stained-glass windows.

Dust floated lazily in the golden light.

The building groaned softly with age.

Shelves stretched from floor to ceiling, packed so tightly that even mice had trouble squeezing between them.

Most people who visited the library complained about the smell.

Kai loved it.

Old paper.

Dry ink.

Weathered leather.

To him, it smelled like adventure.

He gently slid the final book into its place before hopping down from the ladder.

"Perfect."

"You've reorganized the wrong shelf again."

Kai turned around.

His older sister, Lyra, stood with folded arms, trying—and failing—to look annoyed.

She wore the family's dark-green librarian robe, embroidered with a silver feather quill on the shoulder.

The emblem had belonged to the Aldrens for generations.

"I didn't reorganize it," Kai protested.

"I improved it."

Lyra sighed.

"You sorted them by historical significance instead of catalog number."

"Isn't that better?"

"For historians."

She walked over and nudged one book back into place.

"For everyone else, it's a nightmare."

Kai grinned.

"I'll memorize where everything is."

"You already have."

She smiled despite herself.

That was Kai.

The curious one.

The boy who remembered where every forgotten manuscript rested, yet forgot where he left his own shoes.

The youngest son of the Aldren family.

A family whose bloodline had served as librarians since the dawn of professions.

Long before adventurers founded guilds.

Long before kings claimed kingdoms.

Long before the System ranked people by classes and levels.

The Aldrens protected knowledge.

Not treasure.

Not relics.

Knowledge.

At least...

that was what they had always believed.

The library sat at the edge of the farming village of Ashgrove, where forests stretched farther than roads and travelers rarely visited unless they had lost their way.

It wasn't impressive.

Its roof leaked during heavy rain.

The windows rattled whenever storms rolled across the valley.

The walls needed fresh paint.

But hidden beneath those weathered beams rested thousands of books collected over centuries.

Some described monster habitats.

Others recorded forgotten kingdoms.

Ancient recipes.

Medicine.

Architecture.

Music.

Craftsmanship.

Poetry.

Even children's fairy tales.

Most villagers believed ninety percent of the collection was useless.

Adventurers only wanted books about combat.

Mages searched for spellbooks.

Everyone else ignored the rest.

Kai preferred the neglected shelves at the very back.

Books so dusty no one remembered placing them there.

He wandered toward them now.

Rows of faded leather bindings greeted him like old friends.

One title immediately caught his eye.

One Hundred Uses for Moss.

Another.

The Complete Guide to Maintaining Stone Bridges.

Another.

Traditional Candlemaking Before Mana Lamps.

Kai smiled.

"So many forgotten things..."

His fingers traced cracked spines with almost reverent care.

Most people laughed at books like these.

Why study candles when magic existed?

Why learn farming techniques when enchanted fields tripled harvests?

Why memorize old construction methods when earth mages built walls in minutes?

Because...

someone once thought they mattered.

Kai believed knowledge never truly became useless.

Only forgotten.

"You found your cave again."

His father's voice echoed gently behind him.

Edric Aldren approached carrying a stack of returned books.

His beard had begun turning silver, though his shoulders remained surprisingly broad from years of hauling books instead of swinging swords.

His class wasn't Warrior.

Nor Mage.

Nor Priest.

Above his head shimmered a simple title.

Level 41 Librarian.

An ordinary profession by modern standards.

Most adventurers mocked it.

Kai thought it looked dignified.

Edric placed the books onto a nearby table.

"You always disappear back here."

"They're interesting."

"They're old."

"Exactly."

His father chuckled.

"I used to say the same thing."

Kai blinked.

"You did?"

"When I was your age."

Edric picked up One Hundred Uses for Moss.

"I read this three times."

Kai's eyes widened.

"Really?"

"Your grandfather caught me trying to grow medicinal moss in the attic."

"...Did it work?"

"For two days."

"What happened?"

"The goats ate everything."

Both laughed.

Edric's smile slowly softened.

"You remind me of him."

"Grandfather?"

"No."

"You."

Kai tilted his head.

"What?"

"The younger version of me."

For a brief moment, something unreadable passed across his father's face.

Pride.

Sadness.

Regret.

It vanished almost immediately.

"Come," Edric said. "Your mother wants everyone downstairs."

Lunch inside the Aldren household was always noisy.

His mother, Elara, believed silence belonged in libraries—not dining rooms.

Fresh bread.

Vegetable stew.

Roasted chicken donated by grateful villagers.

Lyra argued with their younger brother Finn over whose turn it was to clean the archive basement.

Finn insisted dust was "part of the atmosphere."

Their mother disagreed.

"You'll clean it."

"But—"

"No."

His father laughed into his soup.

Kai barely noticed.

His attention remained fixed on an old leather notebook sitting beside his plate.

Elara tapped the table.

"Kai."

"Hm?"

"Eat first."

"I'm reading."

"I know."

"So?"

"So food."

He reluctantly obeyed.

Halfway through lunch, Finn suddenly asked,

"Father... why don't people become librarians anymore?"

The room fell strangely quiet.

Edric lowered his spoon.

"Because the world changed."

"How?"

"People stopped valuing knowledge."

"They value strength."

Silence.

His mother quietly nodded.

"Heroes defeat monsters."

"Mages conquer dungeons."

"Kings build armies."

"Librarians preserve history."

Finn frowned.

"But history sounds important."

"It is."

"Then why does everyone laugh at us?"

No one answered immediately.

Finally...

Edric smiled.

"Because they don't know what they're losing."

Kai looked toward the hallway leading back into the library.

Thousands of books.

Thousands of forgotten ideas.

Waiting.

The afternoon passed peacefully.

Travelers came and went.

Children borrowed adventure stories.

Farmers returned agricultural manuals.

An old hunter requested a bestiary.

Everything felt ordinary.

Until sunset.

The first warning came from the village dogs.

They barked.

Not excited barking.

Fear.

Then came horses.

Fast.

Too many.

Kai looked toward the windows.

Dust clouds rose along the road leading into Ashgrove.

His father was already moving.

"Lyra."

"I see them."

"Lock every archive door."

His mother's expression hardened.

"Finn."

"Basement."

"Now."

"What about Kai?"

Edric looked directly at him.

"Stay with your mother."

"I can help."

"No."

"I've trained."

"You've trained to organize books."

Kai clenched his fists.

His father wasn't wrong.

He had never awakened a combat class.

His status was painfully ordinary.

Name: Kai Aldren

Class: Apprentice Librarian

Level: 7

Strength: Poor.

Agility: Average.

Mana: Below Average.

Combat Skills:

None.

The front doors burst open.

Villagers stumbled inside.

"They're here!"

"They're armed!"

"They're wearing black armor!"

"Mercenaries!"

A heartbeat later...

The library doors exploded inward.

Wood shattered across the stone floor.

Five armored figures marched inside.

Each wore dark cloaks stitched with a crimson eye.

The leader removed his helmet.

Cold blue eyes swept across the shelves.

"So."

"The rumors were true."

Edric stepped forward.

"This is a public library."

"You are trespassing."

The mercenary smiled.

"We're not here for your money."

"We're here for your books."

Kai froze.

Books?

Why?

The leader slowly drew his sword.

"Hand over every volume concerning obsolete professions."

"Ancient skills."

"Pre-System civilizations."

"And forgotten techniques."

No one moved.

His father answered calmly.

"This library does not surrender knowledge."

The mercenary sighed.

"I hoped you'd say that."

Steel flashed.

The first bookshelf crashed sideways.

Books scattered across the floor.

Villagers screamed.

Another mercenary kicked over a reading table.

Pages flew through the air like frightened birds.

Kai stared in horror.

Years of history...

Thrown aside like garbage.

"No!"

He rushed forward instinctively.

A heavy armored boot struck his chest.

The world spun.

His body slammed into a shelf.

Pain exploded through his ribs.

He gasped for air but couldn't breathe.

The mercenary barely looked at him.

"Pathetic."

His mother ran toward him.

"Kai!"

Before she reached him, another mercenary blocked her path.

Edric charged.

For the first time in Kai's life...

He saw his father fight.

Not with a sword.

With knowledge.

Edric pulled a heavy encyclopedia from a nearby shelf and smashed it into an attacker's face before using the rolling ladders and narrow aisles to force the armored men into bottlenecks.

Years spent inside the library had become a battlefield advantage.

Lyra hurled thick dictionaries with frightening accuracy.

Finn shoved shelves over to slow the invaders.

For a moment...

It almost worked.

Then the leader moved.

One strike.

Edric's improvised defense shattered.

A second blow sent him crashing across the room.

"Father!"

Kai forced himself upright.

His legs trembled.

His body screamed in pain.

Still...

He ran.

He didn't have a weapon.

Didn't have a skill.

Didn't have strength.

He only had the desperate hope that somehow...

Somehow...

He could protect them.

The mercenary leader didn't even bother drawing his blade again.

A single punch caught Kai in the stomach.

Every ounce of air left his lungs.

He collapsed onto the stone floor, unable to move.

Helpless.

Completely helpless.

From where he lay, he watched black-cloaked figures tear through shelves, ripping apart catalogs, throwing ancient manuscripts into sacks, searching for something only they seemed to understand.

One mercenary shouted,

"Captain!"

"Nothing in the main archive!"

"Search the restricted stacks!"

The captain's eyes narrowed.

"I knew this family was hiding something."

He slowly turned toward the Aldrens.

"You've protected these books for generations."

"Tell me where the Forgotten Collection is..."

"...or we'll burn every shelf until we find it."

For the first time in his life, Kai realized there were people who feared old books more than powerful weapons.

And whatever lay hidden within his family's library...

Was worth killing for.
