Teron Gorefiend, I am...

With Gorefiend's items restored, there is but one last piece to this puzzle: A host. <The ancient shadowmoon spirit's lips curl up to form a wicked grin.> Surely you did not believe the fairy tale that I told you. The Altar of Shadows is my prison. Without your help, I would have been stuck here for all eternity. Now, I will take over your body and you will destroy my captors and break these bonds. Refuse and we will both be stuck here forever. Teron Gorefiend will be free!
