In the year 20XX in the city of Barcelona, Spain seven Magi prepare for a war over an ancient relic. A relic called the Holy Grail, said to grant any wish to the winner of this war. Each Magi now a Master of a summoned familiar called a Servant, the embodiment of a Heroic Spirit, prepare for a Battle Royal to have their wish granted. Servants are summoned under a class befitting to their nature; the Saber class, Archer class, Lancer class, Rider class, Caster class, Berserker class, and Assassin class all with their own set of proficiencies and weaknesses. The identity of a Servant’s class gives anyone a general set of weaknesses they may have, but a Servant’s Heroic Spirit’s identity can be a nearly deadly mistake. A single mistake or miscalculation of Servant’s and Master’s skill set can end in the loss of Holy Grail or even life itself. In a battle royal of epic proportions what pair of Master and Servant will prevail to see their greatest wish granted? Who will claim victory in the Sixth Holy Grail War? Whose side will Fate take?
