Castle Pradeux

Castle Pradeux was a location on Prefsbelt IV, and by extension a place within the Naval Academy on Prefsbelt IV. It was surrounded by various hills. By the time of the creation of the Galactic Empire, 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 links 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.
