Stolas appears to be narcissistic, decadent, exigent, and has a regal quality about himself. His house appears quite large containing many pictures of himself along with his clothing around him and he complains of being lonely. As with many demons, and the denizens of Hell in general, Stolas has a highly questionable moral compass. Being a regular client of Blitzo and his service, Stolas is responsible for ordering the deaths of mortals to advance his own agenda.
