In this sense, it is similar to the Throne of Heroes. The Automaton has monitored and recorded all occurrences on the Earth (including the activities of human heroes) since time immemorial.

Servant data is taken from the Moon Cell Automaton, a spiritual computer system built on the lunar surface by a pre-human civilization and discovered by humans in the year 2032. There, the Moon Cell orchestrates a replication of the Holy Grail War using a system called Serial Phantasm or SE.RA.PH, which handles the summoning of Servants. The world is set in a school called Tsukumihara Academy, a fictional place existing within an artificial environment called the Moon Cell. As of the 2030s, the world's mana was completely gone. The universe of Extra shares the events of the Fate/stay night universe until a 'certain major incident' in the 1970s that caused the world's mana to start drying up causing it to split off into its own separate universe. With only an enigmatic 'Servant' by their side, they face both friends and foes in battles to the death to not only gain possession of a mysterious object known as the 'Holy Grail', but also to find the answer to the most important question of all: 'Who am I?' Setting
