Gea: The name for the world. Used in reference to the soil, land, and the spirit that dwells within the world as well.
Gea is made up of three (known) landmasses, Amorica, Ushia, and Oforica. It has many different races, though their individual origins are not known. The races, while tending to be geographically clumped, are not necessarily exclusive to one location.
