What exactly is Gortha? It's not exactly a place, as much as a thing. A volcano. In the center of the Stromm Badlands is where it sits, in a mountain range that shares it's name. It's very active, and so the Stromm Badlands are usually covered by it's thick sooty cloud.
A large desert that stretches all the way to the mountains of Xell in the west. Not much need to explain about it, other than that it's usually clouded with sooty clouds from Gortha.
