Nabonidus is a mysterious, highly powerful being who was introduced saving Ravat from Blackout's betrayal. He is a very quiet, softspoken individual, but is dangerous enough that even Ravat knows better than to cross him. It is unknown what species Nabonidus is, whether his existence is unique, or whether he used to be a normal being. What is known is that he is an enemy of Zev Raregroove and his allies, and is on uneasy terms with Ravat, although the two are willing to work together in cases that would be mutually beneficial.
