The GeoFront in Rebuild of Evangelion. The GeoFront is a massive subterranean cavity, underneath Tokyo-3. The Nerv Headquarters building complex was build in the center of the GeoFront. The GeoFront is a massive sphere, with a wide disk centered in the roof. Within the center of this flattened disk is the “Ceiling City” of Tokyo-3’s movable buildings poking downwards as they are retracted below the surface. In the exact center of this cavern there is a deep trench, shaped like an inverted pyramid which underground instalations of the Nerv HQ building descend into. The above floor level pyramid-shaped Nerv HQ building is located slightly off-center, extending off of the central trench.
