The Holy Grail. To some, it was a relic from ages past, a collector's item. To others, it was a holy symbol and the object of reverence. However, the Grail I sought was neither. It was the Holy Grail of Fuyuki. In truth, the Fuyuki's Grail was 'false' - and by false, it was not the cup that Jesus of Nazareth drank from before his death, but a ssupposedly omnipotent wish-granting device designed to pierce the Swirl of Origin and find thr root of all magic. 

I was rather skeptical of the Grail's omnipotence, but it was the only chance I had for revenge. You must be wondering why I seek revenge. Everyone that I knew, everyone that I loved, was torn away by denizens of evil. I had never loved my parents - and when my mother died, my father and I left for a remote island in the Phillipines, abandoning my homeland. There, he had revealed that he was a magus, and an outlaw one at that. He sought immortality - and on Alimango island, my home at the time, he picked up a student. She and I became friends, but after a failed experiment she was transformed into a Dead Apostle, an undead creature similar to a vampire. Before I knew it, the whole island had turned except for my father and I, and when I realized that this was all his doing I... killed him. He was still my father, and that would never change, but he was evil. And such evil must be purged - similar to a cell apoptosis - a symptom that manifested when a cell mutated. That cell commited suicide for the good of the many, preventing harm. And my father was part of that cell called evil. It was only natural that I removed him.

I was rescued from that island by a mercenary, a monster hunter of sorts. Her name was Natalia. I didn't trust Natalia at first, but she was my only friend - and person I knew in the world, so I warmed up to her eventually. However, I was forced to kill my mentor. I don't think I'm ready to talk about that yet. Afterwards, I continued the life that she had given me and disregarding the ideals of magehood, I used the ancient art of magic as a mere tool alongside more modern, vulgar methods - such as guns. My work as an assassin specializing in killing the proud magi who ignored modern technology earned me the title of 'Magus Killer'. 

Stolen from Royal Road, this story should be reported if encountered on Amazon.

My past may have been bleak, but ever since I was hired to compete in the Holy Grail War of Fuyukiand was given these Command Seals, sigils of a master, I saw hope. Despite the fact that I would lose my spouse - the homonculus Arsviel von Einzbern - in this war as a sacrifice to the Grail, an perhaps more, I could finally claim vengeance - if you could call it that - and purge the evil from this sick world. 

I looked out the window at the snow blanketed German forest then at the mercury pentacle in front of me, preparing myself for the summoning of the Heroic Spirit that would bring me victory in this Holy Grail War - my Servant. I took a deep breath, ensuring my catalyst - a bloodstained Linden leaf - was in place, then began chanting.

"Let silver and steel be the essence.

Let stone and the archduke of contracts be the foundation 

Let my great Master Emiya be thy ancestor

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.

I hereby declare. 

Your body shall serve under me. 

My fate shall be your sword.

Submit to the beckoning of the Holy Grail 

If you will submit to this will and this reason…Then answer!

An oath shall be sworn here! 

I shall attain all virtues of all of Heaven. 

I shall have dominion over all evils of all of Hell! 

From the Seventh Heaven, attended to by three greet words of power,

Come forth from the ring of restraints,

Protector of the Holy Balance!"
