Long ago, to calm the elemental spirits causing chaos across Klein Continent, Grand Sorcerer Huey placed elemental gemstones capable of regulating nature in five altars, protecting them with magic seals. Each decade, Huey and his clan members would set out on a journey to maintain the altars, but twenty years ago, Huey vanished. With no one to tend to the gemstones, equilibrium slowly gave way to natural disasters and the spread of the Dead Zone. That's when Huey's familiars summoned a protagonist from another world: Eiden. Following his arrival in Klein, Eiden assumes the mission of the vanished Grand Sorcerer. He learns to regulate his essence—similar to Huey's—and through close bonds with clan members learns to harness its power, so that the seal of the neon gemstone may be released and its strength restored.
