Synopsis: The start of the Great Holy Grail War starts. During the previous war, the Greater Grail disappeared after the Third Holy Grail War. Years of silence went by, and around the time the Fifth Great Holy Grail War would have happened, the Yggdmillennia family announced their secession from the Mage’s Association. They also declared they had possession of the Grail. The Association sends fifty magi out to retrieve it, where all but one were slaughtered by a single Servant. The survivor manages to activate the reserve system, which allows the summoning of fourteen Servants. There are two factions participating in this war: the Black Faction, those who want to protect the Grail, and the Red Faction, those sent to retrieve it. This war is on a bigger scale where the Grail itself summoned its own Servant to watch over the conflict.
