Fate/Labyrinth

Prequel to Fate/Prototype. Young Ayaka Sajyou wakes up to a normal morning breakfast with her father and older sister, Manaka, unaware that a battle of frightening proportions has now begun in Tokyo. This battle is the Holy Grail War, the first of a series of mutual slaughters where seven Magi and seven Servants team up together to fight in a battle royale to win the Holy Grail, a mystical omnipotent wish-granting device to have their own wishes granted. As each of the Seven Masters summon their Servants and fight, more of the mysteries surrounding the Holy Grail are revealed, culminating in a epic battle that will test loyalties, forge new alliances, and makes one question, who is the real Master in this Holy Grail War?

The setting of Fate/Apocrypha is a parallel world to Fate/stay night where the Greater Grail was removed from Fuyuki after the Third Holy Grail War and disappeared for many years. Around the 2000s, around the same time as the Fifth Holy Grail War would have happened, the group that plundered the Grail, Yggdmillennia, openly declares their secession from the Mage's Association and that they are in possession of the Grail. The Association dispatches fifty magi to retrieve it, but all but one are instantly slaughtered by Lancer of Black. The one remaining manages to activate the reserve system of the Greater Grail, allowing for the summoning of fourteen Servants in total. This marks the start of the Great Holy Grail War in Trifas, featuring two different factions, the Black Faction, whose members are part of Yggdramillennia, and the Red Faction, whose members were sent by the Mage's Association with the exception of one from the Church. The Grail itself also summons Ruler to act as a mediator of the Holy Grail War.

Aslaug is the daughter of dragon-slayer Sigurd and valkyrie Brynhild. She long slept under the great harp of magical silver, and what awaited her upon her awakening was a world of men without gods. The Scandinavian Peninsula of the 9th Century. There she had a fateful encounter with Ragnar, young warrior of the vikings, the bold men who claim to serve the disappeared Norse gods and to be braves deserving of guidance to Valhalla. This truly was the chance meeting between the last Valkyrie and the last Einherjar.

When Lord El-Melloi II, the later Waver Velvet, gets asked to claim his inheritance over Adra Castle, he travels there with his apprentice Gray to do so. But they are not the only ones called that way. The will of the previous owner states that the assembled contestants—including Luviagelita Edelfelt—must compete in a game of wits to win the castle.
