Well, presumably they could start out as an Imp or Shadow and spend thousands of years “leveling up”
Of course, that has not been working out for me. But then for some reason, I don’t have a lot of initiative. If I were to be honest, I think I just enjoy chillin with my pipe a bit too much.
If you can have a Greater Shadow maybe a Shadow Prince?
Very cool title at the least. Ooh, maybe the shadows are ruled by The Prince of Shadows?
