The Ω System ("Omega System") is a massive space fortress housing Proto Ω and the Original Zohar. Apparently, Ω System is an incarnated version of Old Miltia, for the planet was ripped apart from the inside out as the Ω System emerged. The Ω System has been fitted with many puzzles and locks to keep unwanted visitors out, as well as a pair of large guardian mecha (one of them taking the form of a full scale Cathedral). Proto Ω and the Original Zohar are housed in the core of the Ω System.
