Well, Evil Authorlord is already taken by Viridian of Viridian Dreams, so, is there a title that you would prefer? Anyone have any suggestions for something clever and pithy? Or does "The Giant" just work?
EDIT: As for the term "Word Of God", you are the Creator, so far as OOTS-verse goes, and that phrase is the accepted general term for pronouncements from the creator of an artistic endeavor. So it's not really religious in anything but an ironic sense. Perhaps, though, thinking of it as an acronym for Gaming Operations Designate works? :)
