The Sub-Sphere is a large white sphere on top of Mainframe's Principal Office. It is the main access for the Core Control Chamber and contains the system portal generator. Usually the Sub-Sphere has nothing on its surface but a small gray platform is inside it. This platform will come out of the sphere and sit on top so that Phong and anyone else can stand on the Sphere and use its functions. The Sub-Sphere will open when the portal generator is to be used. There is an axillary Sub-Sphere stored in the Archives that can quickly replace the current one if it is destroyed. (Bad Bob)
