Sector Zero is an area of Norion explored in Metroid Prime 3: Corruption. It houses a large military base containing three Fedtech Plasma Generators, three Landing Sites, and a large Control Tower that controls the orbital Defense Cannon. The base is crafted in Jovian steel and mounted with a large planetary defense system. Relatively advanced accommodations for the Federation Marines stationed there can be inferred, as they are at least capable enough of protecting the remote planet, and they are among the first to test Phazon Enhancement Devices, highly experimental technology in itself.
