It's a war between mages who summon heroes from across time to take hold of the Holy Grail, a wish granting device. I am one such hero. The title I would go by in that war is 'Lancer' and that is my role. Every warrior is slotted into one of several types, which determines their power and abilities. Saber, Archer, Lancer, Rider, Caster, Assassin and Berserker.

[Enkidu smiles.] Of course... this is only the usual classes. Sometimes oddities happen but I'm not privy to that knowledge. My purpose is to fight the others and win for my master, until we're the only ones. Then we get to make a wish on the grail. Or so it goes.
