There are multiple factions in Fate/Regalia that are trying to gain dominance in OLYMPUS. However, due to the fact that almost all factions are now headed by young people that have different goals from the ones issued them before they came to OLYMPUS, there are no open wars between these factions. In fact, most of these factions live in a harmony in the academy city, if not counting for the occasional squabbles between the factions of Holy Church and Dead Apostles.
There are total eleven factions in OLYMPUS, and seven of these are so called "Player-Factions" that the players themselves are in. These Player-Factions are divided into various sub-factions that determine the actual dorms where the characters sleep, and various other things. The factions are.
