These are the place names that I use. Some are what the places are known as by the locals, some are the Shela names. Many countries don’t yet have definite borders.
The seas are all named by the Shela. The Holy Sea is believed to be the location of Vee Pretniska, residence of the god Roamuhs. The Fire Sea was once the far east of the Shela world (ie. the place where the sun came from). The Stone Sea is named for its apparent lack of any strong ocean currents, the Running Sea is named for the opposite reason.
