Underworld

The Underworld is the subterranean land under Odianica that the corrupted races fled to after the Twilight Wars. It is the current homeland of the Ghoul, Ghast, Drow, Duegar, Ogre, Gorgon and Wraith. The caverns are pitch black and the only known entrance is at Khorboldar in Ozerunth. In the Underworld, only the Drow and Duegar have cities. The other races roam the Underworld in tribes, trying to escape and attack the surface. No one knows anything else of what is down there. What is known is that there are more terrifying creatures that live there other than the corrupted races.
