Pelagius' Hip Bone

 is an item given by Dervenin when the quest The Mind of Madness is accepted. The bone appears to be the pelvis of Pelagius the Mad, the previous Jarl of Solitude.

Function
According to Dervenin, the bone is essential to gaining access to Sheogorath's realm, hidden within the Pelagius Wing of the Blue Palace. Item is still kept after quest is completed. It can be sold (after the completion of the quest) to general stores such as Belethor's General Goods, or used to decorate a player's house.
