Motherhorn

Motherhorn is the Theater-Castle of Endelyn Moongrave, the Hag that rules over the splinter-realm of Yon. It is full of mechanical and theatrical contraptions that are powered by the near-constant lightning storms that plague Yon's shadowy peaks. A mountain pass leads to huge doors into a shadowy corridor. Beyond a black curtain a massive amphitheater is carved into the mountintop. It is a dramatic and terrifying place to give a performance, but that is what's demanded by Endelyn of most visitors.
