Rancor Summit is a 200' jagged spire of bone sited in the ruins of Ugidreth. This colossal bone was a gift from Thasmudyan to his highest priest at the time, Katrana Dumu-Loc. It is said that this bone was the spine of some long dead monstrosity floating in Chaos. The spine was moulded with tons of bones to form walls and chambers. Rancor Summit served as the palace for the former rulers of Ugidreth.
