One of newest addition in the Fate anime series is Fate/Apocrypha which is a TV anime which will premiere this coming July 1, 2017. A new trailer for Fate/Apocrypha had been unveiled on its official website together with the announcement of the show’s release date. The anime will premiere in July 1st as a part of the Summer 2017 anime lineup.
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 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. (via TYPE-MOON wiki)
TLDR: Yggdmillennia grabs the greater Grail and screws everyone, thus creating the two factions. (via Agnes Nguyen)
