Shirou Emiya believed that the destruction of the Holy Grail in Fuyuki City would mean the end of conflict, the end of the wars created by the Grail itself. Apparently fate decided to kick him in the face to prove him wrong for the second time in a year and an half. With the presence of the Greater Grail still there, despite the Holy Grail itself being destroyed, the conduit to the Throne of Heroes was opened, allowing Servants to be summoned by mages in order to aid them in the coming battles. No magus is safe. Welcome to the Magus Wars.
