The Regime (Earth-7)

Ancient Times
The Regime existed in their own solar system centuries before life on Earth first appeared. They became extremely advanced and began travelling the galaxy, judging planets on whether or not they were worthy of survival. If they were, they were inducted into the Regime, if not, their planet was destroyed. Unbeknownst to them, they were being drawn to Earth by the stirring of a future god-like being.
