Tales of Eternia is an action japanese role playing game, with real time battle scenes (combos and spells can be assigned to the face buttons). It is a port of the original PS1 game, which was localized as Tales of Destiny II in the US (not to be confused with the Japanese Exclusive title Tales of Destiny 2, an actual sequel to Tales of Destiny)

The game is set in the fantasy world of Inferia, follows the story of a young hunter named Reid Hershel and his friends, Farah and Keele, as they meet a mysterious girl who speaks an unknown language. Their subsequent quest to discover her origins leads them across a dimensional boundary to an entirely different realm known as Celestia, where they become involved in an age-old conflict between the two worlds.

It would later inspire a 13-episode anime co-produced by Production I.G loosely based on the game's plot.
