Dringoth is a spirit living within the Skeleton of a Bosmer. He can be found in Bone Orchard, a large cemetery in the southern area of Grahtwood, Valenwood. He will request for the Vestige to help find and save his skeletal friends. This will then initiate a quest, Keeper of Bones.
The Vestige will find a talking skull on the ground north of the Southpoint Wayshrine. Dringoth will say that Worm Cultists are creating undead in the Orchard. The Vestige will need to tie Dringoth's skull to their belt and find the rest of him scattered across the Orchard.
