In the Kingdom of Carnava, in an age when magic supports everyday life and civilization itself, peace is maintained by the queen's knights and the Rev Magic Association. Sixteen years before the game's story begins, monsters called Beast Fiends start to appear, destroying everything in their way. Mattias, leader of the Magic Association, uses the evil Demon Blade to try to seal the source of the fiends, but is sealed away himself by the elemental witches. (wiki)
