The world consists of seven islands, each with a city: Honglian City, Lvzao City, Lanhai City, Qingyun City, Chengyan City, Huangliu City, and Ziling City. Everyone in this world carries a Heavenly Crystal within them. Through special methods, people can awaken their crystals and use their power. The first people to awaken their Heavenly Crystals believed themselves to be supreme beings, so they spent vast resources building an aerial island at the center of the seven islands: the "Divine Realm."
