Graven is a vast underground realm ruled by the Firstborn Mandragor. Graven is a vast realm of caverns and passages that spread out from the city of Hellas that lies at it's centre.
Mandragor, Lord of Tyranny, rules over Graven with an iron fist. The souls of the damned are forced to work in the mines for all eternity, digging up metals and other minerals which are turned into weapons in Graven's many forges.
