Castle Pradeux was a location on Prefsbelt IV and, by extension, a place within the Prefsbelt IV Naval Academy. It was surrounded by various hills. By the time of the Galactic Empire's creation, and the restructuring of the Academy system, the ancient stones of the castle were dwarfed by soaring buildings and towers, in addition to the 12 Mounts, each named for exceptional naval battles. A multi-kilometer-long passage linked Castle Pradeux with the heart of the range, which itself led to the Naval Crypt. It was often used during Graduation, where the newly-made midshipmen travel and pledge him or herself to the service.
