I'm the DM of my campaign, but one of my players runs a cleric of "the Uber-God," a sort of supreme good deity, of which Hieroneous, Pelor, etc., are just aspects. (The player came up with the concept.)
We never did settle on a name for this Uber-God, though - we mostly just call him "Ube" (phonetically: "Oob"), short for "Uber."
