Great Cataclysm

a long time ago, the world was one land mass similar to pangaea: a cataclysmic event caused the land to split into six parts, each separated by a deep, unconquerable sea. slowly, the ancestor race evolved into the different races that are known today. the ancestor race evolved differently on five of the isolated continents and the sea, resulting in the diversity of races there are today

additionally, during the great cataclysm, some of the molten core of forigo was pushed to the surface. when exposed to venelum, it took on sentience and bipedal form, becoming the grivau race.
