Boneyard Keepers are giant, skeletal undead warriors in Dragonplate Armor and armed with Dragonbone Greatswords, who protect the Oblivion plane known as the Soul Cairn. They stand at least as tall as Giants, although unlike the Giants of the mundane realm they are belligerent on detection of an interloper.
Like the lesser guardians of the Soul Cairn, the Bonemen, they dissolve into liquid black puddles upon defeat. They are substantially more powerful fighters than Bonemen. They are generally found around major structures in the Soul Cairn.
