A fantasy world on the Yori Continent where seven mystical Yori stones—Sun, Moon, Fire, Water, Wood, Metal, and Dark Yori—are the fundamental source of magic and civilization. Six major races inhabit this world: Humans, Elves, Dwarves, Orcs, Dragons, and Shadow Clan. Society is structured around Yori stone affinity, creating a magic nobility class. The Yori Wheel Alliance maintains peace among races. Technology blends medieval aesthetics with Yori-powered innovations including flying vehicles and teleportation arrays.
