Fate/Yhwach? No its Fate/Zaegar

As Yhwach found himself in the void, floating aimlessly, he couldn't help but feel a sense of frustration at his current situation. The void offered nothing but emptiness, and he longed for something more substantial, even if it meant enduring Zaegar's terrible jokes.

Yhwach: Would I truly entertain Zaegar's jests over this void?

Yhwach muttered to himself, contemplating his circumstances. Despite his immense power and influence in the worlds he had traversed, being stuck in this void felt like a punishment.

After a moment of silence, Yhwach shook his head. 

Yhwach: No, I mustn't dwell on this. There's no use in lamenting over things I cannot change.

he resolved, his voice echoing into the emptiness.

With a resigned sigh, Yhwach decided to make the most of his situation. 

Yhwach: Very well, if this is where I am to remain for now, then so be it. Perhaps a rest is in order.

he mused, acknowledging that even a being like him needed moments of respite.

As Yhwach prepared to close his eyes and embrace sleep, a sudden blaze of light pierced through the darkness, forcing him to shield his eyes with his hand. Annoyance flickered across his features as he squinted towards the source of the blinding radiance.

Yhwach: For a mere light, you sure are annoying.

As Yhwach's eyes adjusted to the intense light, he realized that it wasn't just any ordinary illumination. Instead, it was a swirling vortex of energy, pulsating with power and mystery. Intrigued despite himself, Yhwach watched as the vortex expanded, revealing a figure standing within its center.

Yhwach: Who... or what are you?

Yhwach's voice echoed through the void, tinged with a mixture of caution and curiosity.

As the red light intensified and shot towards Yhwach, he instinctively activated Blut Vene Anhaben to protect himself. However, to his astonishment, the beam of light effortlessly pierced through his defense, shattering it like glass. Panic surged through Yhwach as he watched his hand begin to disintegrate into particles under the onslaught of the erasing light.

Yhwach's mind raced, grappling with the realization that he was on the brink of being erased from existence itself. Desperation clawed at him as he searched for a way to counter the impending doom.

Just as Yhwach feared the worst, a deep, guttural laughter echoed within his consciousness. It was Zaegar, his Inner Hollow, stirring within him, seizing control in this dire moment of need.

Zaegar: Hahahaha! Looks like you've gotten yourself into quite a mess, Yhwach!

Zaegar's voice reverberated through Yhwach's mind, brimming with amusement at the predicament they found themselves in.

As Yhwach's consciousness began to fade, Zaegar seized control of his body, his grotesque mask manifesting over Yhwach's face, obscuring his features with its eerie visage. With a sinister grin, Zaegar's crimson eyes glowed with an otherworldly intensity as he faced the oncoming threat.

The red light, now panicked at the sudden shift in Yhwach's demeanor, attempted to retaliate with another beam of erasing energy. However, before it could fully materialize its attack, Zaegar, now in control of Yhwach's body, lifted their hand and intercepted the beam with ease.

The light, realizing its imminent defeat, desperately attempted to augment its power, but it was too late. Zaegar, fueled by the thrill of battle and his insatiable hunger for destruction, devoured the beam of light, absorbing its energy with a ravenous hunger.

With a triumphant roar, But as his victory echoed through the void, a sudden shift occurred, and Yhwach, now under Zaegar's control, found himself being summoned to a grail war.

Scene Break - Five minutes earlier

All the seven Servants had been summoned, leaving none for her to participate in the 'war'. Even so, her heart leaped with joy and she could not stop herself from dancing with giddiness.

???: Requirements are met. Initiating the summoning.

She did not need a regular Servant with a normal class. 'It' was a Servant that would allow her to fulfill her wish.

She could summon 'it' because she knew there were flaws in the system of the War and that the Grail itself had been corrupted.

But for all it was worth, she still held an emotionless gaze.

For 'it' was an existence so evil and corrupted that 'it' would bring forth nothing but destruction to the world.

The incarnation of 'All the World's Evil'.

Once she had summoned it, the melody of ruin would automatically begin to play from within the miracle.

Raising a delicate hand, she stated the special incantation she prepared with her dull tone.

Fill the void, tenfold, then empty it clean, Destroy the cup fivefold, and rebuild its gleam. In this cycle of darkness, let chaos reign, Till all that remains is the blackened bane.

Oh cursed one, cursed be, both world and soul, Hated by all, yet hatred takes its toll. Outside of order, bound to chaos' light, Despised by order, yet despising the right.

Subject and sire of chaos, dual in the role, Life's a lie, the truth lies in death's dark stroll. Life's curse, death's salvation, soothe the pain, From Gaia's plane, I summon thee, full of disdain.

Heed my call, the avatar of Akasha's breath, Oh Harbinger of death, in this voided space.

The whole cave started to glow with ominous purple light, a sign that her summoning was successful.

Of course it was, she knew it would be successful.

In the middle of the cave stood what appeared to be a rectangular box made of stone. It was without a doubt the prison where 'All of the World's Evil' was sealed.

The girl was calmly towards the 'cage', all the while thinking how many years, months, weeks, days, hours, and seconds, had waited for this moment.

???: Soon... Kosuke...

All she needed to do was to break it open. Once it revealed itself, it would automatically begin spreading its corruption to every corner of the world.

???: Show yourself... Angra Mainyu.

Black tentacles appeared from beneath her feet, from her left, and from her right, it was all around her. The whole cave had been covered with black tentacles that the young girl had created.

She was an extraordinary existence.

As a magus, her magic circuits were beyond measurement, to the point where the word phenomenal would severely undermine its quality, and with its abnormal, unprecedented composition, combined with her connection to the Root, she could accomplish things that no other magus could.

It was not even an exaggeration to put her on the same level as those who carried the miracles from the Root, the Magicians.

The girl commanded her tentacles to break open the prison of All the World's Evil, and so they did, releasing the Zoroastrian god, and-

Well, that was what she thought would happen.

Zaegar: FFFFUUUUUUUUUUUUUUCKING HELL!

She almost jumped as a fist suddenly burst through the prison. A very... human-like fist. No, it WAS human.

Zaegar: DAMMNNN LIGHTTTTTTTTTTTTTTT!!!

Numerous fists joined the first as the side of the prison shattered, the entire construct fading into black ash not long after. 

The being inside of the prison did NOT look pleased.

He didn't resemble the physical incarnation of All The World's Evil.

She stared, her gaze meeting his hollow mask eye socket, which glared back at her with an intensity that sent shivers down her spine.

Zaegar: Right, hello there! So I was just about to devour that stupid fucking light, but guess what? Some random bitch decided to ruin my meal. Care to explain why you'd commit such sacrilege? 'Cause you REALLY don't wanna see me in a cranky mood.

The girl, taken aback by the sudden appearance of Zaegar, stumbled backward, her expression a mix of shock and fear. She had expected the arrival of Angra Mainyu, the embodiment of All the World's Evil, but instead, she found herself facing this chaotic entity.

Her mind raced, trying to comprehend the situation and formulate a response. She knew she had summoned an evil being, but she hadn't anticipated this level of unpredictability.

???: I-I... I apologize, I didn't mean to interrupt your... meal.

Her voice trembled as she spoke, her eyes darting nervously between Zaegar's menacing form and the remnants of the shattered prison.

Zaegar: Oh, spare me your apologies, sweetheart. You're lucky I'm in a relatively good mood today. Otherwise, I'd have torn you limb from limb for ruining my fun.

His voice dripped with malice, his hollow mask twisting into a malevolent grin.

Zaegar: Where is the offering? If you summoned me, then you must have some kind of offering. Mountain Dew fountain? Mountain of Doritos? Little Mac-shaped punching bags?

He looked around and realized he was inside a dark cave. No one but himself and the girl stared in a confused manner.

Alarms roared in his mind as he fixed her with an intense gaze.

Zaegar: Why am I here in this dark place where no one could hear us if we tried to kill one another or worse?

???: ...This is... a rather odd form you've taken, Angra Mainyu.

Zaegar: Angry Man Jew? Did you want to summon an angry jew? Sheesh, I sure hope this isn't South Park. Anywho, THE FUCK, GIRL?!

The girl dismissed his anger and simply carried on with life like it was nothing. This did not amuse him.

???: No matter. Servant Avenger, I am your Master. You may address me as Emi Enishi.

Judging by his gaze, he couldn't care less about her name. He was the primordial Hollow also Yhwach's Inner Darkness, so that was to be expected. Nonetheless, she carried on.

Emi: I have called upon you to carry forth the true purpose of your existence. To participate in the Holy Grail War and bring forth corruption and destruction upon this world.

Zaegar's eyes gleamed with interest at Emi's words, his twisted grin widening as he listened to her command.

Zaegar: Ah, now that's more like it! A little chaos and destruction to spice things up. Well, lucky for you, destruction's my middle name. You've got yourself a deal, sweetheart.

He bowed mockingly, his hollow mask casting eerie shadows in the dimly lit cave.

Zaegar: But before we get down to business, let's get one thing straight.

Zaegar's twisted grin widened as he stepped forward, his crimson eyes glinting with malice. In a flash, he appeared in front of Emi, his hand wrapping around her throat with a vice-like grip.

Zaegar: Let's get one thing straight, sweetheart. I take orders from no one. Not you, not her, not even the Soul King himself.

His voice was low and menacing, reverberating through the cave with a chilling intensity. Emi gasped for air, her eyes widening in fear as she struggled against Zaegar's iron grip.

Emi: Release me... now...

Her voice was barely a whisper, choked out between gasps for air. But Zaegar paid no heed to her plea, his grip only tightening around her throat.

Zaegar: You think a little command seal will control me? How amusing.

With a scoff, he glanced down at the command seal on Emi's hand, a cruel smile playing across his lips.

Zaegar: You're a fool if you think you can control a force as chaotic as me.

Emi's hand trembled as she summoned all her strength, pressing the command seal against Zaegar's skin with a desperate hope that it would compel him to release her.

Emi: Drop... me...

Her command was laced with authority, fueled by the power of the command seal. For a moment, it seemed as though Zaegar would obey, his grip loosening slightly.

But then, with a wicked laugh, he tightened his hold once more, defying the authority of the command seal.

Zaegar: Nice try, sweetheart. But I'm afraid it's going to take a lot more than that to control me.

Emi's heart sank as she realized the futility of her attempt. She was at the mercy of this chaotic entity, with no means of escape.

Zaegar: Now, let's talk about our little arrangement, shall we? You wanted chaos and destruction, and I'm more than happy to oblige. But remember, you summoned me for a reason. And until I decide otherwise, you're at my mercy.

With a sinister chuckle, Zaegar released Emi, allowing her to stumble backward, gasping for air as she clutched her throat.

Zaegar: Consider this a warning, sweetheart. Cross me again, and you'll regret it.

Emi's eyes narrowed as she regained her composure, glaring at Zaegar with a mixture of defiance and confusion.

Emi: What are you? Why didn't you kill me? Isn't it in your nature to destroy and kill all humans? You are Angra Mainyu, after all.

Zaegar threw his head back and laughed, the sound echoing through the cavern with a chilling resonance.

Zaegar: Oh, sweetheart, you're half right. It is in my nature to bring chaos and destruction, but I'm not some pawn named Angra Mainyu. My name is Zaegar, and you can stop blabbering about that shit now.

His hollow mask contorted into a wicked grin as he sauntered closer to Emi, his crimson eyes gleaming with amusement.

Emi: ...Zaegar?

The girl was exasperated. Could it be she had made a mistake somewhere in the summoning ritual? But it couldn't be. 

Plus, for some reason, she knew nothing about this man after hearing that name. Usually, information from the Root was sent into her head once she identified something, but there was nothing. Absolutely nothing.

She focused her sight on the Hollow as she discerned his class and his parameters, something that every Master in the war could do.

Once she did, she became speechless. For the first time, her face contorted in genuine shock.

Emi: Servant Class... Foreigner?!

Zaegar: And not even a droplet of alcohol around. Worst. Summoning. Ever.

__________________________________

A threat had invaded the world.

An anomaly that could- no, would result in absolute annihilation had descended. The world had a mechanism to respond to threats such as this one.

The Counter Force is composed of Gaia, the will of the planet, and Alaya, the will of humankind.

Gaia deemed this... invading abomination too much of a threat, and it saw Alaya, whose agents were Heroic Spirits, as the main culprit.

Gaia did not want humankind to destroy it. Humankind was the prime danger to the planet.

Gaia screamed for help. A wish to eradicate humankind for the planet's survival.

Far beyond the stars, in each of the celestial bodies belonging to the solar system, they came to life. 

Alaya, knowing that the incoming threat was beyond any of its agents, employed a certain being to supervise the anomaly and, hopefully, aid it in repelling annihilation.

This was, in essence, a massive wager with results ending on opposite sides of the spectrum, Salvation or Destruction. But there was no other being capable of repelling the imminent threat.

And so, time took a different path. All because of a foreign drifter.

Fate/Yhwach? No its Fate/Zaegar: Start

- Class Skills -

Existence Outside The Domain - EX: Denotes a being that hails from beyond the known universe. Being a living anomaly, the Servant is free to interact and change the world as he sees fit at full power. His power alone can override any rules of the universe and even bend them to his whims. He is not aligned with Gaia nor Alaya and instead is recognized simply as a force of absolute power over his own being.

Divinity - A: Although Hollow, his absolute might is a concept beyond anything divine, and is sometimes seen as an almighty existence. However, Zaegar sees godhood as something below him and frequently clashes with deities out of boredom or simple spite. Additionally, he is rather proud of his Hollow race and prefers to be a Hollow with godlike power instead of an outright god. Thus, his Divinity decreases from EX to A. 

- Personal Skills -

Magic Resistance - EX: Despite his refusal to know any magic, since he views it as a waste of time, his endurance is such that virtually no Magecraft or Magic in existence can faze him. He can casually shrug off attacks that alter reality or causality without any effort, and even the highest of Noble Phantasms can only amount to an annoyance at the very best. This means, on the other hand, that his current Master does not need to supply him with mana, allowing him to use his Noble Phantasms to their fullest capabilities at all times.

Independent Action - EX: Due to his extreme laziness and take-no-shit attitude, combined with his power, no being in the world can truly control him. Command Seals are rendered ineffective since his sheer force of will override the command. Normally, Servants must have a Master, even after being summoned. Because Masters must provide their servants with Mana to keep them in the world, or they will be unable to retain their physical forms. Some servants have skills that prevent this outcome, but all of them have a time limit. Except Zaegar.
