Nah, but really the only word I could find that fit what I was looking for was "dictator." "Dictator" seemed a dumb title, and Potentate has Latin origins. Prometheans strike me as our world's Rome (especially being named [i]Prometheans[/i], with Prometheus being the Greek mythological figure who brought fire to man). So... Potentate was the best word.

You could've gone with Despot or Tyrant, both of which didn't start out with negative connotations. :D Though with the Prometheans being sort of Germanic language-wise you could just call your rulers Kings, since I believe the word King has it's origins in the early Germanic languages.

EDIT: Even if it'd be a bit boring.
