Strongest Incubus System

Elizabeth’s face contorted.

It wasn’t a subtle change. It wasn’t a simple hardening of expression. It was as if something too ancient to fit into human features had decided to emerge. Her skin seemed to stretch for an instant, the veins beneath the surface darkening like living roots, her red irises sinking into an abyssal hue that swallowed any trace of light. Her teeth lengthened slightly, not grotesque—but predatory. Elegant. Wrong. The air around her vibrated as if being compressed by an invisible force.

Her whole body trembled.

Not from weakness.

From rage.

A rage so fierce, so primal, that it seemed to come from an era before the very city that had dared to attack her. Her shoulders rose and fell with breaths too controlled to be natural. She clenched her fists with brutal force—strong enough that her nails pierced her own skin. Blood trickled between her fingers, thick and dark, dripping onto the cracked marble of the courtyard.

Each drop that touched the ground made the surrounding shadows tremble.

The mansion behind her still burned.

The smell of destruction mingled with that of her own fury.

She slowly raised her face to the sky.

And the sky seemed to hesitate.

”It’s been years...” she murmured, her voice carrying an echo that wasn’t entirely human, ”...since I used my strength.”

The wind began to swirl around her.

First as a breeze.

Then as a growing whirlwind.

The crimson mist exploded from her body in dense waves, and then—with a sound like the breaking of an ancient seal—something tore through the air behind her.

Wings.

Not symbolic.

Not illusory.

Gigantic bat wings, materialized in pure solid darkness, expanding outwards with an imposing grandeur that defied any human scale. Each wing stretched for hundreds of meters, casting a shadow that covered the ground, the trees, the remains of the destroyed gate, and part of the city itself in the distance.

Three hundred meters wingspan.

Each side.

The initial flapping of these wings was not just a movement.

It was an event.

The impact violently displaced the air, sweeping debris across the courtyard, extinguishing small flames, and forcing everyone present to stand firmly on the ground. The sunlight was swallowed under the veil of darkness cast by that colossal form.

It rose from the ground slowly.

Not in a leap.

But in ascension.

As if the sky itself were giving way.

The wings opened completely.

And the shadows they created began to move. Not naturally.

But like a living sea.

The edges of the darkness rippled, trembled... and then began to fragment.

Thousands.

Tens of thousands.

Bats emerged from the shadows cast by their wings, detaching themselves like living pieces of solid night. Small, swift, red eyes gleaming like sparks. They spun around her in chaotic spirals, filling the sky with a deafening sound of wings beating in unison.

The city below began to notice.

People pointed.

Guards dropped their weapons.

Mages felt the shift in mana and paled.

The swarm grew.

And grew.

Until the sky above Mirath was partially covered by a pulsating cloud of dark life.

Elizabeth hovered in the center.

Small compared to her own wings.

And, at the same time, infinitely larger than everything below.

She closed her eyes for a moment.

And felt.

Every drop of blood spilled.

Every magical signature of the invaders.

Every trace of hostile intent that still stained the city air.

When she opened her eyes again, they weren’t just red.

They were stars of carnage.

”Find all my enemies.”

The order wasn’t shouted.

It was whispered.

But it reverberated like an absolute decree.

The swarm exploded into motion.

The bats scattered in all directions, descending through the streets, infiltrating windows, disappearing into alleys, traversing rooftops, and plunging into basements. Each creature carried a fragment of her consciousness, an echo of her will.

They weren’t searching randomly.

They were tracking.

The first group of assassins was hiding in a warehouse north of the city, believing the plan had been successfully executed. One of them was still smiling, talking about the promised reward.

The shadow entered through the crack in the door.

A bat landed on the ceiling.

Then two.

Then twenty.

In seconds, the air in the warehouse was saturated with wings.

They tried to react.

Too late.

The bats converged like a living tide, covering faces, penetrating mouths, eyes, ears. Screams were muffled under the weight of hundreds of small bodies that were not just animals—they were extensions of her own darkness.

When the swarm receded, the ground was covered in emptied corpses, the flesh withered as if decades had passed in seconds.

And that was only the beginning.

In an abandoned tower, a mage responsible for the ritualistic explosive began to feel the air grow too cold. He tried to conjure a defensive circle.

A shadow fell upon him.

And, out of nowhere, Elizabeth was there.

Materialized in the center of the room, wings partially folded behind her, eyes gleaming with absolute judgment.

”You touched my house,” he tried to plead.

There was no time.

She raised her hand.

The blood within him answered the call like an obedient traitor.

His skin cracked in crimson fissures before collapsing inward, compressing bones and organs until only a shapeless heap remained on the floor.

She disappeared again in a burst of bats.

Street after street. Rooftop after rooftop.

Secret cellars.

Hidden rooms.

The swarm found.

She judged.

No scream lingered in the city for long before being silenced.

With each death, the fury did not diminish.

But it refined itself.

It became surgical.

Precise.

The leaders tried to flee.

Horses prepared.

Secondary gates.

Underground tunnels.

But the shadows were already there.

Always one step ahead.

One of them—the commander of the attack—ran through the underground galleries believing he was safe in the ancient routes beneath the city.

He felt the wind before he heard it.

When he turned, he saw only red eyes in the dark.

And then she walked towards him.

No wings now.

No spectacle.

Only presence.

”You made a statement,” she said softly.

He fell to his knees.

She inclined her head.

”I answered.”

The mist enveloped the tunnel.

And the silence that followed was absolute.

When the swarm began to return to the sky, the city was different.

Quieter.

As if it had understood something fundamental.

Elizabeth hovered again above Mirath, her wings still enormous, but already beginning to slowly retract.

She took a deep breath.

The fury still burned.

But she was satisfied.

For now.

War had been declared.

And she had just reminded the world why her name was whispered, not spoken.

And as the shadows retreated back to her wings, a thought crossed her mind like a silent promise:

Whoever touches what is hers...

Disappears.

The night seemed to hold its breath as Elizabeth found what she was looking for. Between arid mountains and a dry forest that had never received enough light to flourish, stood a fortress carved into the rock—invisible to human eyes, camouflaged by ancient runes and layers of illusion that distorted the surrounding space like a broken mirror. But shadows don’t hide the secrets of those who rule them. And she was the absolute sovereign of darkness.

The bats she had scattered across the sky began to return in waves, plunging from the clouds like black rain. Each carried fragments of vision, echoes of conversations, the smell of blood and gunpowder, the metallic sound of blades being sharpened. Thousands of perceptions collided in her mind at once—and she absorbed them all without hesitation. One pierced an illusory wall, revealing the void where there should only have been rock. Another slithered through a narrow crevice, revealing subterranean corridors illuminated by bluish lanterns. And then she saw.

The symbol carved in black iron above a large underground hall: the insignia of the Akalizeht Shadow Guild—a moon split in two by a vertical blade.

Elizabeth smiled.

One of the bats landed silently on the upper window of the base, a narrow opening protected by magic too common to stop it. Its red eyes flashed one last time in the sky—and then its entire body dissolved into a stream of black smoke that swept across the night like a silent lightning bolt.

The next instant, the bat exploded into shadows.

Elizabeth appeared in the center of the main hall.

The impact of her presence was not physical—it was spiritual. The temperature plummeted. The blue torches flickered violently. The air became heavy, as if space itself were being compressed. About forty assassins were gathered there: some seated at a large stone table, others sharpening weapons, two interrogating a prisoner tied to a chair. They all stopped.

She was there.

A black dress billowing like living smoke, red eyes gleaming with supernatural intensity, hair floating as if submerged in invisible water. Behind her, shadows pulsed like a colossal heart.

”Shadow Guild of Akalizeht...” — her voice echoed in multiples, as if dozens of versions of her were speaking at once, overlapping. — ”You usually do work for the Black Union and the underworlds of the big cities.”

She took a step forward.

The floor cracked beneath her heel.

”Then I want to know...” — her eyes scanned the hall, finding each face covered by black masks. — ”Why did you attack my home? My subordinates? My dear friends?”

Her aura began to expand.

Some assassins tried to move — but their bodies wouldn’t obey. Their muscles locked. Their hands froze inches from their weapons. It was as if invisible chains had been tied around their bones. ”Besides hunting... my husband.”

The last word came out low.

And terror took physical form.

One of the men tried to scream, but the sound died in his throat. The prisoner in the chair began to cry without understanding why. The leader present in the hall—a tall man in a red cloak and ornate mask—managed to take a half-step back before falling to his knees, not by choice, but because his legs simply gave way under the crushing pressure.

Elizabeth tilted her head slightly.

”I asked a question.”

The silence was absolute.

Then the man in the red cloak began to laugh. Not out of courage—but out of despair.

”D-do you think... it was... our decision?” he forced the words through clenched teeth. ”We received... a contract...”

Elizabeth appeared before him before the sentence was finished.

There was no perceptible movement. She was simply there.

She grasped his mask and ripped it off with a dry snap, revealing a pale, sweaty face.

”Whose?”

He opened his mouth—and his head exploded.

Not by her doing so.

A black rune etched into his tongue glowed for a second before detonating his skull from the inside out. Blood and bones splattered across the hall.

Elizabeth didn’t blink.

”Interesting.”

She turned slowly to the others.

Some began to cry. Others tried to force their bodies to react. One managed to move a finger—just one—before the shadows beneath his feet rose like living serpents and pierced his chest, exiting through his back in a grotesque explosion.

The first body fell.

Then the second.

She didn’t run.

She didn’t scream.

She simply walked.

Each step was followed by inevitable death. A man managed to free an arm and throw an enchanted dagger—the blade melted in mid-air before touching her. Another tried to activate an explosive seal—his own shadow rose and broke his neck.

The floor began to slip with blood.

”You made a mistake,” she said calmly as an assassin was slowly crushed by an invisible pressure that bent his bones inward. ”If you had attacked only me... perhaps I would have considered this a challenge.”

She stopped before a hooded woman who was trembling violently.

”But you touched what belongs to me.”
