Long ago, to calm the elemental spirits causing chaos across the Klein Continent, Grand Sorcerer Huey placed elemental gemstones capable of regulating nature in five altars, protecting them with magic seals. Every decade, Huey would take his clan members to visit the altars to maintain the gemstones. However, twenty years ago, Huey vanished. With no one to regulate the gemstones, the equilibrium was slowly lost, leading to natural disasters and the spread of the Dead Zone. That's when Huey's familiars summoned the main character from another world: Eiden.
