The small chiliocosm had experienced eight Epochal Cataclysms. However, no matter which epoch it was, Controllers were actually at a disadvantage. Be it against the Celestial Devils or those medium chiliocosm factions, the local Controllers were at a disadvantage.

Be it the Celestial Devils or the medium chiliocosm, they were far from what local Controllers could compare to.
