Hundreds of years ago, in an effort to calm the elemental spirits that were causing chaos across the Klein Continent, Grand Sorcerer Huey placed elemental gemstones capable of regulating nature in five altars which he then protected with magic seals. Every decade, Huey would take his clan members to visit every altar to maintain the gemstones. However, some twenty years ago, Huey vanished without a trace. Without anyone to regulate the gemstones, the equilibrium began to disintegrate, causing natural disasters to occur and the Dead Zone to spread. That's when Huey's familiars used a mysterious technique to summon the main character from another world: Eiden.
