Welcome to Overlord of the Abyss.

This is a story about power, survival, and growth in a world where Talents define everything.

The beginning is only the first step.

CHAPTER 1: OVERLORD OF THE ABYSS

SCENE 1: "The Weakest Son"

The room smelled of medicine. Bitter. Suffocating.

It clung to the air like something that refused to fade.

Lucius van Venus lay motionless on the bed, his frail body trembling beneath damp sheets. His skin was pale—almost lifeless—while cold sweat soaked through his clothes.

His chest rose… then fell…

Slow. Uneven. Weak.

"He still hasn't woken up?"

A voice echoed from beyond the door, edged with worry.

"No… the physician said his condition worsened last night…"

Footsteps lingered. Then faded.

Silence returned.

Inside the room—

A finger twitched.

Darkness.

Endless darkness.

Where… am I?

The thought surfaced slowly.

Then—

Memories flooded in.

A collapsing noble household.

A second son—frail, overlooked, forgotten.

A talent that never seemed to manifest.

Quiet disappointment.

Unspoken pity.

Lucius.

"…So I've taken over his body."

The realization settled without resistance.

No panic. No confusion.

Only awareness.

This wasn't a dream.

This was real.

A new world.

A new life.

He exhaled softly.

"…Then I'll survive here too."

Not out of pride—

But necessity.

Because that was all he had ever known.

Suddenly—

A cold voice echoed within his mind.

[Condition Met]

[Foreign Soul Detected]

[Initializing…]

Lucius' awareness sharpened.

A system…?

---

SCENE 2: Awakening

Pain struck without warning.

Sharp. Violent. Unforgiving.

"Tch—!"

His eyes snapped open as air rushed into his lungs.

The world came into focus—

A clean white ceiling.

Curtains swaying gently.

The faint scent of herbs.

Reality.

"…So this is it."

His voice was weak, barely above a whisper.

He raised his hand slowly.

Thin. Fragile.

Unreliable.

"…This body won't last like this."

Not fear.

Just a quiet conclusion.

Creak—

The door opened.

A maid stepped in, holding a bowl of medicine.

She froze.

The bowl slipped—

CRASH!

"Y-Young Master…?"

Her voice trembled.

She stared at him—not just in shock, but uncertainty.

"…You're awake…"

Then panic took over.

"YOUNG MASTER IS AWAKE!!"

She ran.

Silence returned.

Lucius let out a slow breath.

"They actually… care."

Fragments of memory surfaced.

A father carrying too much weight.

A brother who stood firm no matter what.

Servants who treated him kindly despite everything.

"…I see."

He closed his eyes briefly.

"…Then I'll accept it."

Not as a replacement—

But as someone who would carry it forward.

Footsteps approached.

The door burst open.

"Lucius!"

A tall man rushed in.

Behind him stood another—calm, observant.

Julius.

"Are you alright? Can you hear me?"

Lucius blinked, then nodded faintly.

"…I'm fine."

A lie—but a necessary one.

Relief showed clearly on his father's face.

But Julius remained still.

Watching.

"…You've changed."

Lucius met his gaze.

"…I almost died."

A pause.

"…That tends to change people."

Julius studied him, then let out a quiet breath.

"Heh… as long as you're alive."

He turned.

"Everyone out."

The room emptied.

Silence settled once more.

---

[Synchronization Complete]

[Lord of the Abyss System Activated]

A translucent interface appeared.

Lucius' gaze focused.

"…So it's real."

Lucius stared at the numbers.

"…Low."

But not hopeless.

Just a starting point.

"…This can be improved."

His attention shifted.

"…Show Talent."

The screen flickered slightly.

---

[Talent Awakening…]

---

Pain surged again—deeper, sharper.

Lucius remained still, enduring it.

Then—

Space distorted.

He raised his hand slightly—

—and vanished.

A moment later, he reappeared across the room.

No delay.

No resistance.

"…So this is how it works."

His voice was quiet. Thoughtful.

Not excitement—

But understanding.

Teleportation.

Refined.

Reliable.

Another layer followed.

Something deeper.

The Law of One.

His thoughts aligned more clearly.

Connections formed faster.

Cleaner.

More precise.

Lucius closed his eyes briefly.

"…There's potential here."

When he opened them again, they were calm. Focused.

Aware.

Then—

A notification appeared.

---

[Hidden Condition Fulfilled]

[Title Unlocked]

---

Lucius paused.

"…A title?"

---

[Title: Overlord of the Abyss]

Effect: ???

Restriction: Sealed

Condition: Grow Stronger

---

Silence lingered.

Lucius studied the words carefully.

"…Overlord…"

Not excitement.

Not pride.

Just quiet curiosity.

"…I'll need to understand what that means."

The air felt slightly heavier.

Different.

Lucius leaned back slowly.

His thoughts drifted briefly—

To his father.

To Julius.

To the life he had just inherited.

"…One step at a time."

A soft exhale escaped him.

"…First, I survive."

His gaze shifted toward the window.

"…Then I grow."

A faint pause.

"…The rest can wait."

Then—

A subtle chill passed through the room.

---

[Abyssal Entity Noticed Your Existence]

---

Lucius' eyes narrowed slightly.

Not fear.

Not excitement.

Just awareness.

"…So something noticed."

A brief silence followed.

Then—

"…I'll deal with it when the time comes."

No rush.

CHAPTER 2: Whispers of the Unknown

The morning sun stretched across the Venus estate. Its tall spires and marble halls glowed softly in golden light. Dust motes floated lazily in the beams, catching the sunlight like tiny stars suspended in midair.

The servants moved quietly. They seemed lighter than usual, almost as if hope itself made their steps easier. Their voices carried faint excitement, tinged with relief.

"The Young Master woke up," one whispered, barely audible.

"After days…" another replied, trembling slightly.

"It's like a miracle," a third muttered, clasping her hands tightly to her chest.

For the first time in days, the household felt alive. There was relief, even joy, that the Young Master was safe.

Yet inside one room, silence reigned.

---

Lucius stood by the window. His reflection appeared faint against the polished glass. Pale skin. A thin frame. A body that looked like it could collapse under its own weight at any moment. Fragile, weak, mortal.

"…Still weak," he murmured. The words were calm, almost detached. Yet his eyes were sharp. Calculating. Observant.

He lifted his hand slightly.

Step.

In an instant, he appeared behind the window. A faint shimmer of residual mana lingered where he had stood. His chest rose faster. His body trembled slightly from the effort. Even something as simple as moving instantly consumed energy—mana he had not yet learned to control fully.

"…So this is how it feels," he whispered, breathing carefully. His pulse throbbed at his temples. Every blink across the room seemed to burn a tiny sliver of energy. A faint metallic taste lingered in his mouth.

The so-called useless Talent had never been useless. It had only been incomplete. Now, even with partial mastery, it left traces of strain in his fragile form.

A faint curve appeared on his lips. There was a spark of satisfaction.

---

Voices drifted from the corridor.

"…A dungeon appeared," one voice said.

"…Unknown rank," another replied.

"…Monsters are acting strange," a third added.

Lucius listened carefully. Each word sank into his mind like water into stone.

"…Some say it might even be dangerous," another voice muttered, almost in fear.

Silence followed. Thick, heavy, like fog hanging in the air.

Lucius turned from the window. "Not yet," he said softly.

Walking blindly into an unknown dungeon without preparation was the fastest way to die. He knew the risk. He needed proof first. Proof that this world—and whatever strange forces existed—was real.

He stepped toward the door. Every movement was fluid, precise, calculated. If it failed, he would adapt.

---

The Venus estate was more than a simple residence. Beneath its sprawling grounds lay one of its last remaining assets: a controlled dungeon. It had once been a training ground, a source of rare materials, and a tool to maintain the family's influence.

It was guarded. Regulated. A place no ordinary person dared to enter.

Lucius moved through the halls slowly. Servants bowed as he passed. Fear or respect did not matter to him. He observed them casually. He noted the slight changes in their posture and the flickers of recognition in their eyes. None dared to question him.

Finally, he arrived at the dungeon entrance.

A swirling mass of distorted space pulsed faintly, embedded in stone like a wound carved into reality itself. Lucius studied it carefully.

Weak. Fragile. Harmless.

Perfect.

He could sense the dungeon's mana—a soft hum against his consciousness. It was alive and seemed to whisper secrets to those who could listen. He stepped closer, feeling the pull of its energy. Strange. Intoxicating.

Dungeons, he recalled, were anomalies born from unstable mana. They were places where reality warped. Monsters could appear without warning. Treasure could hide in the shadows. Some dungeons destroyed entire villages before anyone noticed. Others were tamed and controlled by nobles or powerful adventurers.

Danger levels were classified as follows:

E-rank: Weak monsters, ideal for beginners.

D-rank: Slightly dangerous; basic combat skills required.

C-rank: Trained fighters required.

B-rank: Deadly; only elites survive.

A-rank: Extremely dangerous; high-level adventurers only.

S-rank: Legendary threats; survival uncertain.

SS-rank: Catastrophic; even powerful lords rarely survive.

Unknown: Beyond reckoning; only legends whisper of them.

The Venus family's dungeon? E-rank. Low danger. But enough for observation. Enough for confirmation.

---

A guard appeared from a side passage, bowing stiffly. "Young Master? This area is restricted," he said.

"I know," Lucius replied, his voice soft but firm. He moved forward, noting every detail: the faint scratches on the stone walls, the lingering scent of damp earth, the subtle shift of mana patterns.

The guard hesitated. "Should I inform the Lord?"

Lucius' gaze met his. Calm. Heavy. Dominant. Yet measured, not arrogant.

"Do you think I came here to be stopped?" he asked quietly.

The guard stiffened. "…No, Young Master," he said.

Lucius continued without another word.

---

He approached the swirling entrance. His reflection rippled across the unstable surface. Weak. Fragile. Mortal. Perfect.

The dungeon's distorted space pulsed faintly. He could feel its energy bending around him, the walls stretching slightly. Shadows twisted in subtle, unnatural ways.

Lucius leaned against the entrance archway. Eyes narrowed. He analyzed every detail: the faint glow of mana, the shifting shadows, the distant, almost inaudible sounds of movement. Patience. Observation. Strategy.

Then, without hesitation, he stepped forward into the swirling void.

The world twisted around him. Light fractured. Shadows flickered. A cold, humming pulse of mana washed over him.

Then—he vanished.

No sound. No trace. Only the faint ripple remained where he had been.

The dungeon had accepted him.

This was real.

A whisper echoed—not in sound, but in thought. Curious. Ambitious. Promising.

Lucius' lips curved slightly. "Yes. I am just getting started," he said softly.

The dungeon called. And Lucius was listening.

---

CHAPTER 3: The First Hunt

> Darkness swallowed him whole.

For a brief moment—

There was nothing.

No sound.

No light.

No sensation.

Then—

The world returned.

Cold air filled his lungs.

Stone touched his feet.

Lucius opened his eyes.

A dim cavern stretched before him, illuminated only by faint blue crystals embedded in the walls. Water dripped slowly from above, each drop echoing throughout the underground passage like distant footsteps.

Drip.

Drip.

Drip.

Drip.

"…So this is a dungeon."

His voice was calm.

Too calm.

Inside, however, his mind was already working.

Analyzing.

Measuring.

Calculating.

The air was heavy with mana. Much denser than outside the dungeon. Monsters thrived in environments like this.

But more importantly—

He could feel his body clearly now.

Weak.

Fragile.

Unstable.

His muscles trembled slightly just from standing still.

So this is the body I have to work with…

Lucius exhaled slowly.

This wasn't unexpected.

The real Lucius had been sickly his entire life. A body that never trained, never fought, never endured hardship.

Yet now—

It had to survive a dungeon.

His eyes narrowed.

In this world, creatures like Skarnlings were considered among the lowest-ranked monsters found inside E-rank dungeons.

Weak individually.

But dangerous in numbers.

They were known for ambushing lone adventurers, tearing apart travelers, and hunting like scavengers in the dark.

Many beginners died because they underestimated them.

Lucius, however—

Had no intention of dying here.

He began walking deeper into the dungeon.

Each step was slow.

Careful.

Quiet.

The ground was uneven, covered in damp stone and scattered bones. Some of them looked human.

Interesting…

So people really did die here.

Then—

A sound.

A growl.

Low.

Hungry.

Lucius stopped instantly.

His eyes shifted toward the darkness ahead.

Movement.

Something crawled along the cave wall before dropping down.

A creature emerged.

Small.

Twisted.

Grey skin stretched tightly across its skeletal body. Its limbs were long and crooked, and its claws scraped against stone as it walked.

Yellow eyes glowed in the darkness.

A Skarnling.

It stared at him.

Lucius stared back.

For a brief moment—

Neither moved.

Then the creature screeched.

And lunged.

Fast.

Far faster than an ordinary human could react.

But Lucius wasn't ordinary.

—Step.

His body flickered.

[Teleportation ]!!!

He Shouted!

Space distorted slightly.

And he vanished.

A split second later—

He appeared behind the monster.

His breathing hitched.

"…That cost more than expected."

Teleportation.

Even a short displacement drained his mana noticeably.

The Skarnling twisted violently, reacting faster than he expected.

Claws shot backward.

Slash!

Pain flared across Lucius's chest.

He immediately stepped back.

A thin line of blood appeared on his skin.

His breathing grew heavier.

"…This body really is trash."

His mana was already dropping.

Just one use of teleportation had taken a noticeable toll.

The Skarnling screeched again and rushed him.

This time—

Lucius didn't teleport.

Instead, he watched.

Carefully.

Its movement pattern was simple.

Straight-line attack.

No strategy.

Just instinct.

At the final moment—

Lucius sidestepped.

The creature stumbled forward.

That was the opening.

Lucius moved immediately.

His hand shot forward and grabbed the back of the monster's head.

The Skarnling thrashed violently.

Claws slashed wildly through the air.

But Lucius didn't hesitate.

His grip tightened.

CRACK!

The creature went still.

Its body collapsed.

Silence filled the dungeon once again.

Lucius stood there for a moment, breathing slowly.

Sweat formed on his forehead.

"…Pathetic."

He wasn't sure if he meant the monster—

Or himself.

Then—

A voice echoed inside his mind.

[You have slain a Skarnling]

[+10 EXP]

[+1 Stat Point]

Lucius froze.

His eyes widened slightly.

"…So it's real."

Another notification appeared.

[Reward Acquired]

[Blunt Iron Sword Obtained]

A sword materialized beside him and dropped onto the ground with a dull sound.

Lucius bent down and picked it up.

The blade was rough and poorly made.

But it was better than fighting barehanded.

"…This will do."

Then—

A translucent screen appeared in front of him.

---

Lucius stared at it in silence.

Low.

Pathetically low.

A normal trained soldier would surpass this easily.

"…So even with god-tier talents…"

He closed his eyes briefly.

"…I'm still at the bottom."

That was fine.

Power wasn't given.

It was built.

His gaze shifted toward the numbers again.

Strength.

Agility.

Mana.

Sensitivity.

Endurance.

Each stat represented survival.

Each choice—

Could decide life or death.

Lucius tapped his finger lightly against the blade of the sword, thinking.

Strength?

No.

Even if increased, it wouldn't change much immediately.

Agility?

Useful… but not enough.

Sensitivity?

Better awareness… but he could compensate with experience.

Endurance?

That would help his weak body—

But it wouldn't solve his biggest issue.

His eyes narrowed slightly.

Mana.

"…That's the problem."

Teleportation.

His strongest advantage—

Was also his biggest weakness.

One use already drained him heavily.

In a real fight—

That could get him killed.

If I run out of mana… I die.

Simple.

Clean.

Certain.

Lucius didn't hesitate anymore.

"Mana."

The moment he decided—

The system responded.

[+1 Point Allocated to Mana]

A faint warmth spread through his body.

Subtle.

But noticeable.

His breathing stabilized slightly.

The exhaustion from earlier eased—

Just a little.

"…Better."

Not enough to change everything—

But enough to matter.

Lucius closed the status window.

His grip tightened around the sword.

Then—

He raised his head and looked deep into the dungeon.

A sound.

Not one.

Not two.

Multiple footsteps.

From the shadows—

Three Skarnlings emerged.

Their yellow eyes glowed in the darkness.

They had been watching.

Waiting.

Hunting.

Lucius stared at them.

Then—

A faint smile formed.

"Good."

His stance shifted.

Sword raised.

Mana circulating slowly within him.

His eyes turned cold.

"Let's test it."

The Skarnlings screeched—

And charged.

Lucius stepped forward.

His first hunt had only just begun...
