This story was originally Merlin Pranks101's Fate Ceteri Stulti Velit, but he put it up for adoption and I got permission from him to edit and then continue his story. All thanks to him for the idea as well as the parts of his chapters that I will use for the first few chapters of this story.

I do not own either the Fate series nor RWBY, and the quote is from the movie The Dark Knight.

Chapter 1: All Legends Have Some Truth

There is a saying that you either 'die a hero, or live long enough to see yourself become the villain.' Ozpin had always vehemently rejected that statement, as even throughout his many reincarnations and hosts he had always maintained his goal of protecting humanity. What he was planning now, however, started to make him doubt himself. After all, bringing back someone from the dead is something that would normally frown upon, especially someone close to him. In fact, despite the many things that he had seen over the years, the idea of doing what he has resolved to do still gives him a small bout of nausea.

Fortunately, the speeches of self-doubt and questioning were promptly put to rest by the arrival of his inner circle, a group of long-time friends that assisted him in fighting against the 'Queen' in this lifetime. The first to speak was a fairly unkempt man with messy black hair and amber eyes tinted with the slightest ruby color. His voice was rough, as if he had a sore throat. "So, Oz, what's so important that you needed to call us all in?" He throws a sour glance at the other man in the trio. "Last I heard, our dear Jimmy was handling security, so there was no need for us to help out."

Before 'Jimmy' could send his retort, Ozpin spoke once more, smiling slightly despite his earlier misgivings. "I was looking through the records of the old world that had been kept in the Beacon vault, and came across something that I felt might be able to help us in our fight against the Queen, and felt that perhaps we should try it out, as any advantage we can gain will be very much welcomed in our fight." He stood up, making a motion that they should follow him as he walked back towards the elevator. "I'd rather not risk her spies seeing what we're about to do, so if we could move this downstairs I would be much obliged."

As they entered, Ozpin touched his hand to a pad next to the floor buttons, resulting in the elevator making an odd chime before closing and rushing down for much longer than normal. As they exited the elevator, it opened up to a large underground chamber, with a pair of pods in the center. One of the pods was empty while the other contained a tanned female, no older than 25, locked into stasis. As every time before, the woman, Amber, was registered as 'Critical Condition.'

What shocked the other three, however, was the series of four interconnected circles drawn on the floor in front of Amber's pod. Each one looked to be of esoteric nature, containing a set of rings, arcs, and lines. The woman of the group, a blonde wearing an old-fashioned white blouse and black skirt, quickly spoke up. "Headmaster, what is this?" Her voice was skeptical as she gazed over the setup.

Ozpin took a deep breath, then answered calmly and confidently. "These, Glynda, were summoning circles once used by a group of… unorthodox scholars in order to manifest powerful beings. I questioned it as well when I first read about it in a coded diary that I had recovered, but I felt that we should at least try it, as there were no mentions of this producing backlash in the records."

'Jimmy,' an obviously military man in a pristine gray uniform as well as a white glove on his right hand, spoke up firmly. "Oz, this is a waste of our time. In the old world, people were much weaker than we are now. Anything they considered to be strong could be easily surpassed by our technology and our Huntsmen."

"What if, James, I told you that these beings were recorded to have the strength to bring down entire fortresses single handedly?" Ozpin's face stayed set in stone, a calm expression donning his visage.

"That's insane! There's no way that's humanly possible, even my flagship would have trouble accomplishing such a task." His voice was no longer calm, he had the tone of someone questioning another's sanity. Qrow and Glynda had similar expressions on their faces.

The man being questioned, however, simply chuckled somberly. "Well, you are partially right. Even if they were once human, it would no longer be accurate to label them as such. People summoned by this ritual were directed for a singular purpose, once upon a time: The acquisition of an item referenced in the diary as the 'great wish-granting cup.' The main reason I wanted to try this was because of a particular line in the text that read 'without the wish-granter, there can be no Servants.' As I understand it, the Servants that they talk about are the summons in question."

"So, then if these Servants are summoned, is there anything we should know beforehand?" Glynda asked this question, studiously preparing for the task ahead. "For example, is there any baseline for a Servant or is it luck of the draw?"

"Servants are restricted into seven classes, so as to limit their number and the destruction they cause. A class defines the general statistics of the Servant, while the individual that is summoned may have their own unique abilities beyond that. Servants themselves, however, are figures of legend. This makes it dangerous for them, as their name can reveal both weaknesses and strengths. After all, what someone died to once, they will most certainly die to again. The classes themselves, however, are simple. Sabers, who were swordsmen. Lancers, who struck with their spears. Archers, raining death from afar. Riders, storming the battlefield on their mounts. Casters, making use of esoteric talents. Assassins, who strike from the shadows. And, finally, Berserkers, chained in a cage of madness.

As they took in his words, an outburst came from Qrow, who had found the hidden meaning in what Ozpin had said. "So, then the people that we end up summoning have already died? That sounds more like mad science than a humane experiment, Oz."

Ozpin sighed, before speaking once more. "That was why i was hesitant to attempt this. After all, it's not like a hero to bring someone back to life solely to fight. In the end, though, we need this advantage. The Queen's numbers are overwhelming us, and I fear that these Servants are the only way to ensure Humanity's continued existence. So then, are we going to attempt this, or not?"

He looked at them, watching as they convened with each other through their eyes. After a minute of silent debate, they all nodded. Smiling at the sight, Ozpin directed them to stand in front of the individual circles, before giving them the command to "Repeat what I say, no mistakes." He waited for the accompaniment of affirmatives before starting his chant.

"Let Silver and Steel be the essence."

"Let Stone and the Archduke of Contracts be the foundation."

"Let Blue be the color I pay tribute to."

"Let rise a wall against the Wind that shall fall."

"Let the four Cardinal Gates close."

"Let the three-forked road from the crown reaching unto the Kingdom rotate."

"Let it be filled. Again. Again. Again. Again."

"Let it be filled fivefold for every turn, simply breaking asunder with every filling."

"I declare that you will serve under me, and that I will grant you victory."

"Submit to the whims of the foolish Grail, and answer its divine call."

"I swear to you, I am everything that is good, and deny all that is evil."

"From the Seventh Heaven, brought forth by the words of power,"

"Surpass the ring of restraint, and come forth, Protector of the Remains."

As they chanted, the circles glowed blue, before erupting in blinding light as the final words leave their mouth. As the radiance faded, four figures were revealed. The three who had just been let in on this secret stared in awe, while Ozpin did so instead with determination and a shred of happiness. The white-haired man in front of him bowed, his pale purple eyes glittering with amusement as he smirks a smirk that Ozpin vividly remembers, and never though he would see again, even after all his reincarnations. "Servant Caster graces you with the magnificence of his presence. Now, dear brother, answer me this: are you the one who is to be my Master?"
