Grandia III takes place in an unnamed world, consisting of a main continent surrounded by the Belion Sea, which is vast, to the point where only one person has flown its breadth, Sky Captain Schmidt. Yuki hails from the village Anfog, on Titalos Island. Much of the world relies on methods of flying, from dragons to planes, which use a magical power source. The Guardians are mystical beasts which reside in the world of Grandia III, hailing from the Verse Realm. They came to Yuki's world after a war broke out on their own, quieting wars in both worlds.
