Hey Fan fiction people this is my first time writing a story and I'm going to write an interesting idea of Fate Story. It would be a college student who is not a mage nor know any mages and Holy Grail War. He found the Holy Grail that was on Grandpa box and found that it summon Heroic Spirit that from legend and myths. This would not be good for him. Disclaimer: I don't own any fate/stay night. I do know my grammar is bad. No need to rub it to my face and I apologize that my story is not very good, it just a idea that was in my head for while.
The Greater Grail, a powerful artifact, created two centuries ago by three magus families for their quest to reach Akasha, the root of the World and to recover the Third Magic. To achieve this they needed a great source of power. The Holy grail was that source and Justeaze Lizrich von Einzbern become the core of the Greater Grail. By summoning seven heroes to fight, the last one standing who had completed a ritual would be granted one and omnipotent wish. That wish is the reason for the Holy Grail War. That is a magus duty this is the entire reason they had spent their years to do. Many believe that the number of souls of the servants kill in the war to make a wish are six but its true purpose requires Seven servant to returning to the root as a way to form a hole directly to the Akasha,the wish of the servants was never meant to be fulfilled and are just sacrificial pawns for them.
The First Grail took place around 1800 it was not even a war at all, it only meant to be a ritual for the three families to reach Akasha. It took around ten years to gather the necessary energy to manifest the Grail. The Three families realized that only one person can utilize it even though they had the same goals, their opinion on how to reach them were different from each other, soon this unforeseen event caused them to break off their alliance. They all agreed to proceed with the system and means to create the Grail but become enemies when it was summoned.
Due it requiring seven Heroic Spirits to achieve the ritual and seven Masters to summon them, The Three Families sent envoy to four outside magi with messages that say join the Holy Grail war to obtain your wish and become Masters. This cause internal quarrel with each other that was not major conflict in the end. It was more or less Holy Grail War beta
The Second Holy Grail War was held around 1860s, which formally take on the name of the "Holy Grail War." But had no rules for the Masters and their servants to follow it and became a murder spree that nobody even survived. This cause the Three Families to create more precise rules and bringing a third party like the Church whose job is to watch over any claim of the Holy Grail. The Church send a supervisor to act as a mediator between the Church and the Mage's Association to keep it from falling into the wrong hands.
The Third Holy Grail war took place in 1930s before World War 2. Now let us speak of the Third Holy Grail War event. One of Three Magus Families the Einzberns a bloodline family had suffered a disastrous defeat in the early stages of the Second Holy Grail War tired of losing out on reclaiming the Third Magic chose to summon a Ruler class Servant to be an impartial authority, who real identity is Amakusa Shirou Tokisada the teenage leader of the Shimabara Rebellion. The summoned Amakusa Shirous was not outstanding in combat nor proficient in Magecraft but he continued to win and survive the war. As the third war drew to a close end a unexpected occurred. One participant of the war was Darnic Prestone Yggdmillennia a Head of the Yggdmillennia clan discovered the chance the Greater Grail and borrowing the power of the military of Nazi Germany with skillful words to operation to seize it. Which the power of military behind him to able plundered it and cause lot of casualtie to exhausted Three Magus Families but he was heavily wounded fight against Ruler who die least . The Greater Grail, forged by the combined labor of all three great families, was plundered by the Nazis.
Now with the Greater Grail in their hands, surely Nazi Germany would be able to rule world as they fit. As it was being transported to Germany, Darnic plan to betrayed Nazi and leading detail about the Grail disappeared without a trace. Before He can do that, the cargo ship that he was on blew up and caused chaos between the Nazi and Mage. Few hours later, the ship sank, along with the casualties, Darnic's body was found, burned to a crisp. A few years later the Mage's Association was attacked from Ghoul, Living Dead and Vampire led by Dead Apostles who sensed their position was weaken. There was major casualties on both sides, even with the help from the Holy Church. During the battle there was a report of missing valuable catalyst, secret blueprints of different family members, and important documents
The Greater Grail disappeared. like a mist, the dream of the three great families dissolved. only few of member still know what is it and spent year look for it, hope the Grail is still out there wait to be found. And so the years went by, until even the youth became elderly.
Around one hundred eighty to the modern time of 21st century. The Greater Grail is now literal cup, who have appear in a box filled with other catalyst. The Holy Grail is still gathering energy around it, while it is being protected by average college student moving back to his grandfather's home. He have no idea what he hold is the most dangerous thing.
