The March of Corruption
Even before the first ray of dawn touched the horizon...
The preparations were complete.
Silence ruled the corrupted forest for only a brief moment before it was swallowed by countless footsteps. The earth trembled beneath the march of an army that had hidden itself for far too long. Dead leaves rose into the air with every step, while black mist rolled across the ground like waves following an unseen tide.
Unlike yesterday...
There was no attempt to conceal their presence.
Today, the corruption marched openly.
Howls echoed through the lifeless forest.
Sharp screeches from twisted bat-like creatures pierced the sky, followed by the hissing of enormous corrupted serpents slithering beneath dead roots. Humanoid creatures shuffled forward with uneven steps, their hollow eyes devoid of reason, while monstrous beasts dragged their broken claws across the earth, leaving black trails wherever they passed.
Every species.
Every shape.
Every nightmare.
They advanced together beneath a single command.
Yet amidst that chaotic procession...
One figure walked in complete silence.
Traka.
His footsteps produced no sound.
His body seemed to merge with every shadow surrounding him, making it impossible to determine where darkness ended and he began. His crimson eyes calmly swept across the endless ranks of corrupted creatures marching before him.
There was no excitement upon his face.
No anger.
Only certainty.
Behind him...
Another figure walked.
His hands weren't chained.
His feet weren't restrained.
Only the heavy black collar around his neck remained, connected to broken fragments of iron that dragged behind him with a metallic scrape.
Clang...
Clang...
Clang...
His movements were natural.
Too natural.
Like a person walking of his own free will.
Yet the emptiness inside his eyes revealed another truth.
There was no resistance.
No hesitation.
No life.
He resembled nothing more than a puppet whose strings remained invisible.
Even the corrupted creatures instinctively kept their distance from him. Some glanced at him with hostility, others with unease, as though they were looking upon something that should never have existed among them.
Traka didn't even spare him a glance.
Instead, his gaze shifted toward the countless creatures marching ahead.
His voice remained calm.
"So..."
"It begins."
The army immediately slowed.
Not because they wished to.
Because every creature instinctively listened.
Traka raised one hand.
"Go."
His single word echoed through the corrupted forest.
The monstrous procession stopped completely.
Silence.
Even the howls disappeared.
Only the wind remained.
Then his voice came again.
"Bring them..."
"...to their knees."
A brief pause followed.
His lips slowly curved upward.
"...No."
His crimson eyes gleamed faintly.
"Break them."
Another silence.
This time heavier than before.
"Every..."
"...single..."
"...one."
The corruption itself seemed to respond.
Dark mist thickened around the marching army.
Black veins spread beneath the earth wherever they stood.
The trees surrounding them twisted unnaturally, their branches bending toward Traka as though bowing before him.
Then...
His final order came.
"...But."
"I need them..."
"...alive."
The army erupted.
Howls.
Screeches.
Roars.
The deafening chorus shattered the forest's silence, frightening countless ordinary creatures hiding far beyond the corruption's reach. Birds burst from distant trees only to be swallowed by the overwhelming darkness spreading beneath the marching horde.
The army advanced once more.
This time...
Faster.
Far above them, the sky had only just begun changing from black to deep blue.
Morning hadn't arrived yet.
Yet the corruption had already begun claiming the day.

II. A Lesson Interrupted
Inside the sanctuary, everything remained peaceful.
At least...
For a little while longer.
Adri stood beneath the enormous tree exactly where Limbo had left her moments earlier. The countless streams of energy flowing beneath her skin had finally settled, disappearing one after another until only a faint current remained circulating naturally throughout her body.
Limbo still hadn't moved.
Even after learning that merely observing wasn't enough...
His curiosity hadn't diminished.
Instead...
It had grown.
He looked at Adri before breaking the silence.
"...If I manage to learn this..."
He glanced toward his own hands before smiling awkwardly.
"...what will happen?"
A small chuckle escaped him.
"It looks..."
"...pretty cool."
Adri couldn't help but smile.
"So that's what caught your attention?"
Limbo shrugged innocently.
"It does."
"It feels... different."
"Not like mana."
Adri folded her arms.
"You'll understand..."
"...once you experience it yourself."
Her answer only made him more curious.
"So..."
He hesitated briefly.
"...will you teach me?"
The smile gradually disappeared from Adri's face.
Her expression became calm once again.
"That..."
"...depends."
Limbo blinked.
"Depends?"
She nodded.
"On whether you're worthy."
The words carried no arrogance.
Only certainty.
"This isn't child's play."
"It isn't some ordinary technique that can be learned because someone finds it interesting."
She slowly raised her hand, gently placing it over her chest.
"This..."
"...is something nature itself cherishes."
"It has existed long before kingdoms."
"Long before cultivators."
"Long before humans believed they understood power."
Limbo quietly listened.
Every word drew him deeper into curiosity.
Adri looked directly into his silver eyes.
"But..."
She narrowed her gaze slightly.
"...Are you really—"
Her words stopped.
Not because she changed her mind.
Because...
The ground beneath them trembled.
A faint vibration spread through the sanctuary.
Limbo's expression instantly changed.
He slowly turned toward the forest.
Another tremor followed.
This one stronger than before.
The leaves overhead began shaking violently.
Then—
Thousands of birds suddenly burst into the sky.
Not one flock.
Not two.
The entire forest seemed to explode into motion as terrified creatures abandoned their nests without hesitation.
Clouds of dust rose beyond the distant tree line.
The vibration became impossible to ignore.
Neither Limbo...
Nor Adri...
Needed another explanation.
They were coming.
The vibrations continued growing stronger.
Not in waves.
Not in intervals.
But continuously.
Each passing moment felt heavier than the last, as though the forest itself was struggling beneath an invisible weight. Dry leaves danced across the ground without the help of the wind, while clouds of dust slowly rose above the distant trees.
The peaceful sanctuary they had witnessed only yesterday was disappearing before their eyes.
Limbo's silver eyes narrowed.
He wasn't looking at the dust.
Nor the trembling trees.
He was watching everything at once.
The birds...
Their direction.
The shaking ground.
The disturbed mana.
The corruption spreading beneath the soil.
His mind instinctively began connecting every piece.
They're not hiding anymore...
Yesterday they observed.
Today...
They're announcing their arrival.
Adri silently stepped beside him.
Her gaze remained fixed upon the horizon.
"...It's faster than I expected."
Unlike yesterday's calm expression, this time there was no room for doubt.
Even someone unfamiliar with battle could tell.
Something enormous was approaching.
Mora slowly stepped out of the house after hearing the commotion.
The moment she looked toward the distant forest...
Her tiny body froze.
"...Grandma..."
Her trembling voice barely escaped her lips.
Neither Adri nor Limbo turned around.
Not because they ignored her.
But because their eyes couldn't leave what was unfolding before them.
The strange chorus gradually reached the sanctuary.
Howls.
Screeches.
Deep growls.
Sharp cries.
It wasn't the voice of one creature.
Nor ten.
It was countless beings calling together.
Corrupted wolves howled beneath the trees.
Bat-like creatures screeched from the sky.
Twisted serpents hissed through the dead grass.
Humanoid monsters roared while dragging broken weapons across the earth.
Every sound overlapped another.
Creating a terrifying chorus that no living creature could mistake.
The corruption...
Had come.
Unlike yesterday, when the scouts moved quietly between the trees...
Today's army hid nothing.
Their chaos itself became their announcement.
Their voices became their declaration.
Their march became their warning.
Every step shook the earth.
Every roar carried corruption deeper into the forest.
Wherever they passed...
The land changed.
Healthy grass slowly darkened.
The soil blackened as though life itself was being drained away.
Roots twisted unnaturally beneath the surface.
Yet strangely...
Nothing immediately withered.
Nothing collapsed.
It was almost as though the corruption wasn't destroying the forest.
It was...
Claiming it.
Pulling every living thing beneath its shadow while allowing it to continue existing under a different master.
Limbo quietly observed the spreading darkness.
"...This..."
His voice remained calm despite the overwhelming pressure.
"...Is this a war..."
He paused.
His gaze drifted across the endless corruption.
"...or something else?"
Even he couldn't answer his own question.
Because ordinary wars ended after victory.
This...
Felt completely different.
Adri slowly exhaled.
Despite the terrifying scene unfolding before them...
Her posture never changed.
Her breathing remained steady.
Her old eyes carried the calmness of someone who had witnessed countless storms before this one.
She remained exactly what she had always been.
An elder.
Someone who refused to panic simply because fear stood before her.
Within moments...
The distance disappeared.
Both sides finally stood facing one another.
On one side...
An old woman carrying years of wisdom upon her shoulders.
Beside her...
A frightened child whose small hands unconsciously searched for comfort she knew no one could truly give.
And standing slightly ahead of them...
The one who had willingly accepted burdens that were never meant to become his.
Not because fate demanded it.
Not because destiny had chosen him above others.
But because he himself had chosen to carry them.
For the people who had shown him kindness.
For the animals that shared this forest.
For the ones he loved.
For the ones he wished to protect.
He stood before an enemy whose origin remained unknown.
Its strength...
A mystery.
Its purpose...
Hidden.
Its existence...
A question no one could answer.
Yet despite every uncertainty...
He didn't step back.
His fingers slowly tightened.
"What can an Adaptive Class truly do?"
Unlike a Warrior.
Unlike a Mage.
Unlike a Tank.
His class possessed no clear role.
Its origin remained unclear.
Its abilities were mysteries yet to be uncovered.
No ancient records spoke of it.
No legends mentioned it.
No teacher existed who could guide him.
Even so...
He stood there.
Ready to clash against a reality that cared nothing for fairness.
Ready to challenge a world whose rules he barely understood.
Not with overwhelming power.
Not with legendary techniques.
But with his own hands.
His own resolve.
And the fragments of a broken magic that had yet to reveal its true nature.
Deep within him...
The Beta Fragments suddenly vibrated.
Once.
Twice.
Again.
The reaction grew stronger with every passing second.
It almost felt...
As though they had recognized something hidden within the approaching army.
Something familiar.
Something they desperately wished to reveal.
If only they could speak.
"...Granny..."
"...Limbo..."
Mora's frightened voice finally reached them.
This time both slowly turned.
Her face had turned pale.
Her small body trembled uncontrollably.
Fear had long since replaced confusion.
She was old enough to understand.
This wasn't another nightmare.
This...
Was real.
Adri slowly lowered herself beside Mora, placing a reassuring hand upon the frightened child's shoulder. Her touch was warm and steady, carrying neither panic nor hesitation. Although her own heart had grown heavier with every passing moment, she refused to allow that unease to reach the little girl.
"Don't be afraid," she said softly.
Her voice remained calm.
"As long as I'm standing..."
"...nothing will reach you so easily."
Mora looked up at her, trying to believe those words. Yet the countless roars echoing beyond the sanctuary made it difficult for anyone to find comfort. She instinctively held Adri's sleeve tighter.
Limbo quietly watched them before turning his attention back toward the approaching army.
False hope...
He hated it.
Words alone couldn't stop what was coming.
Neither could empty promises.
They were all standing on the same boat now, looking toward an enemy whose existence itself defied reason. Whether they wished to fight or not no longer mattered.
The enemy had already arrived.
A heavy silence settled over the sanctuary before Adri slowly raised her head once more.
"...Dark Minions."
The words escaped her lips almost unconsciously.
Limbo glanced toward her.
"Dark... Minions?"
Adri nodded slowly without taking her eyes off the approaching corruption.
"They are born where corruption gathers."
"They live within it."
"They breathe it."
"They walk wherever it spreads."
Her voice became colder.
"And wherever they march..."
"...corruption follows."
Limbo quietly observed the countless creatures advancing beyond the trees.
"So they're not controlling the corruption..."
"They're carrying it."
Adri looked at him for a brief moment before nodding.
"Exactly."
"The corruption itself doesn't choose a direction."
"They do."
"And wherever enough of them gather..."
"...the land eventually belongs to darkness."
Limbo's expression hardened.
That explained what he had witnessed only moments ago.
The grass.
The soil.
The trees.
None of them had begun changing before the army arrived.
The corruption wasn't simply spreading.
It was advancing together with them.
Almost like an invisible tide following their march.
Another violent tremor shook the sanctuary.
BOOOOM!
The trees surrounding the barrier swayed violently as distant creatures rammed into everything standing in their path.
The time for observation had ended.
"We strengthen the barrier."
Adri spoke without hesitation.
Limbo immediately stepped forward.
Mana gathered around his palms before spreading outward in countless thin streams. The familiar transparent barrier surrounding the sanctuary brightened once again as fresh mana poured into its weakening structure.
Unlike before...
This time Adri placed her own hand upon it.
The moment her palm touched the barrier, Limbo felt another stream of energy enter the formation.
Not mana.
Something deeper.
Something purer.
The countless pathways he had observed earlier began circulating once more beneath Adri's skin.
His eyes instinctively followed them.
The energy flowed from point to point before leaving her body and merging into the barrier itself.
So...
That's how she strengthens it...
Not by forcing mana...
But by guiding it.
Limbo silently memorized every movement.
Every connection.
Every fluctuation.
He knew he couldn't reproduce it.
Not yet.
But remembering cost him nothing.
Far beyond the sanctuary...
Hidden among the countless corrupted creatures...
Traka watched everything unfold without moving.
The barrier...
The old woman...
The boy...
The frightened child...
His crimson eyes calmly swept across each of them.
Then...
Almost lazily...
He lifted a single finger.
No words.
No command.
No roar.
Just a single gesture.
It was enough.
The army understood.
The front ranks suddenly exploded into motion.
"Aaaawwoooooo!!"
"Screeeeech!!"
"HISSSSSSS!!"
The corrupted beasts lunged forward together.
Bat-like creatures filled the sky like a black cloud before diving toward the sanctuary.
Humanoid creatures sprinted behind them with terrifying speed, while smaller corrupted beasts crawled across the ground in overwhelming numbers.
At the same moment—
"Area Scan."
Blue mana spread from Limbo's body like ripples across a still lake.
His perception expanded rapidly.
One hundred meters...
Two hundred...
Further.
Further still.
His breathing became heavier as countless pieces of information flooded his consciousness.
Enemy numbers.
Movement.
Distance.
Formation.
Flying units.
Ground units.
Blind spots.
Everything entered his mind at once.
His temples throbbed painfully.
Too much information.
Too quickly.
Still...
He refused to stop.
"I have to find something..."
"Anything..."
"A weakness..."
"A pattern..."
"There has to be one..."
The Beta Fragments within him vibrated even more violently, almost resonating with something hidden deep inside the corrupted army.
Then—
BOOOOM!!
The first wave crashed into the barrier.
Corrupted birds struck the transparent wall with such force that several exploded instantly upon impact, black blood splattering across the shimmering surface before sliding harmlessly downward.
Others weren't so fortunate.
They rebounded violently, their broken bodies thrown back into the charging army.
Yet...
More replaced them immediately.
Without fear.
Without hesitation.
Without stopping.
The assault...
Had truly begun.
