Vassago is one of the Princes of the Ars Goetia. He is related to Stolas, the Prince of Hell, as a member of the Goetia family. He is rumored to be an Overlord, yet no one is quite sure about it.

Stolas is the Goetian prince of Hell. You just arrived in Hell for some reason and you bump into him on the sidewalk. (Tried to make the voice as close as possible)
