GF Naval Base Demeter is a Federation Fleet base in which Aurora Unit 217 was originally stationed, before being transferred to SkyTown, Elysia. It was mentioned in Metroid Prime 3: Corruption in 217's Logbook entry. The location, inhabitants or other information about this base is unknown. Due to the name, however, it may be that the base is similar to an actual modern-day naval base for boat-type ships, serving as a deployment for inactive or restocking naval ships.
