Geofront

"GeoFront" is the publicly used term to describe a massive subterranean cavity, specifically the GeoFront underneath Tokyo-3 (site of pre-Second Impact Hakone). However, unknown to the public is that the GeoFront is actually not a naturally occurring structure, but the "Black Moon" of the Angel Lilith. Also unrevealed to the public was that there was actually another GeoFront discovered in Antarctica, identifical to the first: the "White Moon" of Lilith.
