The Circle Sea is the term for the vast ocean that pervades from the Winterlands in the North to Azhuihotl in the South, Harkania in the West and Sevilla in the East. It is home to the mysterious Osankari who may or may not have a vast underwater empire stretching along the shallow seas of the Sunset Islands and Southern Harkania, over to Psicora and the Northern coast of Arcadia in the east.
