In the land of Luxendarc, four elemental crystals maintain the natural order until an encroaching darkness begins consuming them one by one. A disparate group of young adventurers—a village survivor haunted by inexplicable tragedy, a crystal priestess bound by sacred duty, a mysterious traveler plagued by lost memories, and a disillusioned soldier defecting from her own ranks—find themselves drawn together by circumstance and guided by a diminutive fairy companion. United by a common purpose, they must traverse a sprawling world to restore the crystals and drive back the spreading shadow threatening their realm. Standing against them is a formidable organization willing to use any means necessary to thwart their quest and reshape the world according to its own vision.
