Scientists have managed to locate the cause of this epic catastrophe originated out of an anomaly spawned in the city of Fuyuki in late 2004. Rewind to 2015 where the plot takes you to the Chaldea Security Organization summit at which point it is discovered that all of human existence is in dire peril if no action is taken within the coming year. Fate/Grand Order is a JRPG framed within the popular visual novel reincarnated via some fairly competent franchising initiated by Fate/Stay Night.
