@robindlaws Nevermind the weirdly specific demon names, this dichotomy is similar to Tolkien's middle-earth legendarium! cf. this discussion on ghosts ("Houseless") from Morgoth's Ring (towards the end of "Of Re-birth and Other Dooms of Those That go to Mandos.(33)").

Examples of demons meanwhile: Sauron, Balrogs, Ungoliant, etc.
