Though fictional, several aspects of the game are based on reality. Though not explicitly stated in-game, Aurora's duchy in Austria is located in Carniola. An earthquake that hit the capital of Carniola on Easter Sunday in 1895 is adapted into the game's story, where it causes a nearby dam to burst and the capital to be flooded. Similarly, the land of Lemuria that the player explores throughout the game is based on a supposedly lost continent.
