Ravagog is the ogre capital. This is where King Dimitar lives and rules. It is separated into two parts by the Eventide River, in which one part is in a mountain and the other is underground.
Ravagog is where the old gnomish capital, Serenvale, was until the Ogres took it over. Ravagog is described to be separated by the Eventide (a river) into two parts. Half of it is carved into the mountain, and the other half is underground. The Ogres also removed all the Panakes trees, leaving the roots behind.
