Trivia

 * Wald Uberlisterin's name in the Japanese version of the game was "Elds Leika", which means "The Deceiver of the Forest" in Old Norse (as Wald Überlisterin does in German). However, this name may also be read "Eld Sleika", which means "Faint Flame" in Old Norse, and seems to correspond to the official subtitle given for this area.
