So after just recently cancelling and removing my last Fate series fic, and watching the anime again after a long time, and playing through all three Dark Souls games, I just really had the urge to want to write this the moment the ideas popped into my head. There's a chance I might slip up on keeping specific characters in character but, meh, I ain't perfect, but I'll try my best. I ain't gonna waste any time with authors notes so I'll just get right to it.

Disclaimer: The Fate Series and Dark Souls belong to their respective owners, I own neither of them and if I did, I'd be getting a Fate Stay Night remake into schedule not that I didn't like the first one, I just think a remake would be cool.

Fate/Firelink:

'Prologue'

The time was upon them once more as the Holy Grail War approached for a fourth time.

Kirei Kotomine was given the tasks and assignments necessary to allow him stand on his own in the Holy Grail War. Of course, even if he hadn't went about learning everything he needed to know about magic, he was still confident in his own abilities as a member of the Church to stand on his own against the other opposing masters.

And as he thought about the opposing masters, his thoughts drifted back towards one.

Kiritsugu Emiya.

The man was an enigma.

No matter how much information he tried to find, or did find, none of it told him anything useful about his future opponent.

It didn't matter of course.

In the end, he would fall, just like every other master, and then Kirei himself would stand aside, allowing Tokiomi Tohsaka to take the Grail.

Kirei had already performed the ritual necessary to summon his Servant.

And, suffice to say, he was surprised.

Normally stoic, but anyone would be surprised by such an event.

What he expected to be an Assassin class servant of some kind however only turned out to be something, seemingly different. Maybe.

For starters, when he summoned his servant, more than one emerged from the summoning circle.

They all shared the same appearance.

Said appearance, was nothing like what an Assassin would wear save for a few pieces of their equipment.

They all carried large swords on their backs and held small daggers in their hands.

Their faces were obscured by metal masks, and they all wore the same pointed metal hats.

The wind was slowly starting to settle down from the summoning, the capes of the servants danced in the breeze slightly as they all stood as still as statues, eyeing their master in silence.

Kirei eventually recovered from his brief surprise, his face gaining its usual stoic expression.

Finally, one of the servants stepped forward, "Farron's Undead Legion have answered thy call. We, of the Assassin class, are at thy command. What is thy bidding, master?

That confirmed the servant class atleast. However...

...he was expecting to summon Hassan-I-Sabbah. Who, or what, was this Farron's Undead Legion?

Kayneth Archibald El-Melloi II was originally furious.

Absolutely livid.

Livid that someone dared to steal his catalyst for summoning his servant for the Holy Grail War.

No, actually.

Livid itself wasn't a good enough word to describe just how livid an esteemed Magus of high standing such as himself was.

He swore to the gods themselves that he would track down and make the cowardly thief pay for stealing his catalyst.

Of course, originally furious was just that.

Part of him felt some sort of relief through these turn of events.

For as he summoned his servant with the new catalyst he had brought to him, he was greeted with the sight of not one, but two large figures.

One of them was obviously smaller than the other, nearly standing at human height but clearly much taller than the average human. He was clad in golden armour, his helmet designed to look like that of a lion, and he wielded a long spear.

This was definitely the Lancer class servant he was expecting to summon.

His attention then went towards the other servant.

This one, was large, way larger than the first, and he, to put it bluntly, was, quite fat.

He too was covered from head to toe in golden armour, the armour itself was, rather grotesque, to say the least, and he wielded a very, very large golden hammer that looked like it could squash an entire car in one swing.

Kayneth was beyond surprised, he already had questions as to how he could possibly summon two servants but...

...his eyes drifted towards the spear wielding knight who stared at him in silence.

This was Diarmuid Ua Duibhne?

If so, then what was the story with the large fat servant next to him?

Kayneth's fiancée, Sola-Ui Nuada-Re Sophia-Ri, of the Sophia-Ri family, approached him rather cautiously before quietly asking out, "Kayneth, is this the servant you intended to summon?"

Kayneth was silent for a moment.

The armour the two wore did indeed look ancient, but it didn't exactly match how the hero in question was described in the history books.

Finally however, the servant decided to ease his confusion by stepping forward, kneeling down on one knee and bowing his head, spear held in front of him, "I am of the Lancer class, and have answered thy summons."

The servant looked over his shoulder slightly, looking at the large fat servant behind him.

Said fat servant hesitated for a moment before letting out a quiet, frustrated sigh, and copied Lancer's action, kneeling down and bowing his head.

Kayneth just stared for a moment, before finally asking the question that was bugging him, "Are you Diarmuid Ua Duibhne?"

Lancer shook his head, simply replying, "I am not. My apologies if that displeases you master."

That answered his question.

Rather than summon the intended servant, Kayneth somehow ended up summoning two servants from what he could only assume was a further ancient era before Diarmuids time.

Kayneth didn't know their identities, but to be honest, he didn't really care.

He had two servants, instead of one.

That alone, gave him reason to think that victory was already his.

When the last few remaining days had gone by, the day had come for Tokiomi Tohsaka to finally begin summoning his servant.

He was sure without a shadow of a doubt, that the other masters were already in the process of summoning theirs. No doubt they would want to get ahead of schedule and be atleast a few steps ahead of him and the other masters.

Not that it mattered.

In the end it didn't really make much of a difference when the servant was summoned, unless one master was so foolish in taking too long to summon their servant, in which case that master would be an easy target to eliminate.

But he had a gut feeling all the masters in this Grail War were prepared, and were most certainly summoning their servants at an appropriate time. Kirei had already summoned his servant not too long ago, and according to a message he received, his student had summoned six servants with matching appearances. This had quickly gotten his attention for a moment, but he eventually had to get back to focusing on his own.

Again, Tokiomi had no interest in whether the other masters summoned their servants or not.

It was his own servant that he was interested in.

However, something, must have went wrong.

Something could only have gone wrong for the servant to appear as it did before him.

What Tokiomi was expecting to be his winning servant, completely sent him into a spiral of confusion and shock.

Just...what was this...thing that he was laying his eyes on.

Part of it was human, wearing some sort of golden crown and very old, tattered robes that once looked fit for royalty.

But the rest of it, was an abomination.

An absolute monstrosity that nearly took up more than half of his room.

This was not Gilgamesh.

This could NOT be Gilgamesh.

Tokiomi felt fear take him, and took a small step back as the 'servant' looked down at him with a neutral expression.

"So...thou art the one that summons me to this plane." The servant spoke, his voice sounding mostly human, but there was just something, monstrous there.

Tokiomi gulped, but did his best to remain calm, "I...am...you are, the servant Archer, yes?"

The servant merely replied with a small nod, prompting Tokiomi to add, "Are you...Gilgamesh?"

It was a really stupid question, but Tokiomi just had to know, to be absolutely sure. At the very least, this Archer would reveal his identity on his own.

Archer tilted his head slightly, rising high up into the air on his monstrous body and opening his arms wide, "No. Why do you ask? Am I not suitable enough? Do you lack confidence in me already even though the battle has yet to begin?"

Tokiomi quickly shook his head, "O-Of course not! I am simply...confused. I was expecting...someone else, you see."

Archer smirked, a smirk that sent shivers down Tokiomi's spine, "Worry not then. You have obtained the most powerful being as your servant. Within this Holy Grail War, I shall bring you victory. You, should feel honoured."

Tokiomi took a brief glance up at the crown on his human parts head, then bowed his head a little in respect, "I apologise if I offended you. I am, indeed honoured, to have one such...as yourself, as my servant."

The Tohsaka family patriarch looked up again, just in time to see Archer had already turned away from him and started sliding along the floor like a snail, his hands running across the bookshelves at the side of the room, clearly more intrigued by them than Tokiomi's respect it seemed.

"This...might have just gotten complicated."

It took longer than he would have liked, but Waver Velvet finally managed to finish the summoning circle, even if it did take a majority of his day away.

He didn't mind though.

It was a complex procedure, so it was to be expected that getting the summoning circle just right would take some time.

The ritual for summoning the servant was the tricky part.

Good as he liked to think he was, Waver still couldn't claim to be the most, experienced, when it came to such advanced levels of magic.

Then again, summoning these, servants, seemed to be on a level much higher than that of just magic.

Maybe he just felt satisfied that he stole Kayneth's catalyst and was just imagining the magus' face.

The very thought of it made him want to laugh out loud.

Nonetheless, the summoning process was just as difficult as getting the summoning circle just right.

Just one slight misstep was all it took to mess up the entire thing.

When the summoning circle began to glow in response to his words, he knew he got it right.

An explosion of light followed when he finished and threw him off his feet.

He took his time recovering from his fall before trying to get a good look at the servant he summoned.

When the smoke settled, Waver was taken aback in surprise when he able to make out his servant.

A frail looking yet beautiful woman was seated in the middle of the summoning circle. The robes she wore were somewhat revealing, completely old and in tatters.

Along with the bracelets she wore around her wrists, she also wore a thin silver tiara, and her long, black hair, that extended far down her back and across the ground behind her a little looked a little messy, most certainly in need of a good wash and a good brush.

Waver recoiled at the sight of the servant, who slowly looked up from her knees and directly at him. Though her eyes were closed, she was clearly aware of his presence, "Greetings. You...are my master, no?"

At first, Waver was just to awestruck, but quickly recovered from his state before managing out a reply, "Um, y-yeah! Uh..." He stopped for a moment, thinking of what question to ask.

"I understand. I hope I...can live up to your expectations." The servant said.

Waver hesitated again for a moment, then decided to ask, "Um...what was your servant class again?"

The woman responded calmly, "Rider, master."

That surprised him.

He was atleast expecting some sort of noble looking knight on a horse, or maybe a large man on a chariot. Instead he got, this frail looking woman.

Then again, looks can be deceiving.

And Waver Velvet knew better than most, to never judge a book by its cover.

The summoning ritual took quite a toll on Kariya Matou especially in his exhausted state.

Nonetheless, he was able to perform it successfully, much to his father Zouken's delight.

However, something seemed off.

The servant appeared as expected, and they radiated a powerful aura.

But Zouken was familiar with the power of servants.

And the power coming from this one, far exceeded that of any servant he'd ever felt.

The power he could feel from this servant was completely immeasurable.

So much so that he couldn't help but feel the slightest bit intimidated.

The servants armour was ancient, as to be expected of a heroic spirit. Dark armour of silver and blue, and a dark sword held in his hand, this, dark knight radiated a very dark aura that sent shivers down the spines of both Matou's.

Zouken eventually regained his composure and chuckled, "Well done Kariya, you managed to successfully complete the summoning ritual, and survive. There might just be some sort of hope for you yet."

Kariya frowned, eyes narrowed as he watched the old man leave, "Remember, Kariya, I don't really have high expectations for you right now, so, do yourself the favour and atleast try to prove me wrong a little."

The old man cackled on his way and Kariya did nothing more than glare after him.

When he turned back, he could see his servant was also apparently looking in Zouken's direction.

It was only for a brief moment, the servant slowly looked back at Kariya by the time the latter set his eyes on him.

He wasn't sure how, but something about this servant seemed, not right.

Nonetheless, he too, could feel the overwhelming power coming from him, and this gave Kariya all the assurance he needed that the Holy Grail would be his, and by winning it, saving Sakura and returning her to her mother and sister.

Kiritsugu Emiya had summoned the Saber class servant he intended, however, the servant standing before him and Irisviel did not look even close to what they pictured King Arthur to look like.

In fact, Kiritsugu was starting to convince himself that the servant summoned before him was not King Arthur.

The servant that stood before them towered over them both by a few feet. He looked ancient yes, but...too ancient.

His armour was ash black, it was thin at the arms but heavy plates covered his shoulders and torso, while the cape hanging from his waist were nearly in tatters.

The servants face was obscured by the helmet he wore, a sort of triangular thin slit being his only way of seeing through it.

It was the weapons the servant was holding, that confirmed to Kiritsugu that this servant was not who he intended to summon.

In the servants left hand, a slightly long, sharp and rusty silver sword.

And in his right hand, a very, very large sword that was about as big if not bigger than a human being, the sword itself was ash black just like the servants armour.

Irisviel took a small step back and turned to Kiritsugu, waiting for him to speak.

However, he did not speak.

Despite, this error in the ritual, Kiritsugu could feel a massive aura of power coming from this servant.

In the end, that's all he really needed. A powerful servant.

The silence lasted for a long moment before the servant finally spoke up, his slightly deep voice echoing throughout the entire hall, "And so I have been summoned, and so I answer. So now I ask, are you worthy, to command my sword?"

Authors Notes: A bit of a rushed start but then again, the anime itself kinda just got right to the fun, so why not? Anyway, I'm not sure if I've left enough, specific details describing each of the servants, but I'd like to think I've left enough subtle hints as to who is who. And yes I know I left out Caster, that was intentional, I plan on bringing Caster in next chapter. Also, character tags and pairings are subject to change as I'm still debating on them. As usual, please Review, the feedback is helpful.
