Long ago, the orcs and humans all occupied the same area and warred for land and resources, eventually the human’s superior technology forced the orcs back into a barren valley called Krellscis. The orcs were subdued for years, and though no one knows how, suddenly resurged from the desolate mountains. Krellscis was long thought uninhabitable but the orcs have found a way. They return to Grenund and Xor-Giri as a stronger and more vicious race, if not for the bottlenecks created by the mountainous borders the orcs might have been able to overwhelm the adjacent nations.
Krellscis hasn’t been explored much by reputable eyes, but all accounts is a barren and dead valley, where not a single drop of water or leaf can be found. It is almost completely locked in by mountains and other impassable terrain.
