I'm Really Indescribable

I have shared a feast with ghouls in ancient tombs; I have also traveled with deep divers in the North Sea; I have also traveled through time with the Yisi people, witnessing the rise and fall of dynasties, the rise and fall of nations, and witnessing too many joys and sorrows. People falsely believe that I have the hands of a ghoul, the legs of a deep one, the head of a gug giant, the torso of a black goat, the wings of a Bayaki... The list goes on. However... I'm just an ordinary person who can change bodies.
