Citadel

An unused Space Pirate Data entry in Metroid Prime 3: Corruption centers around the construction of a Citadel on Phaaze. The entry suggests that this would have been a base of operations for the Space Pirates on Phaaze (in the final game, no Pirates are seen on the planet, although they guard it from the Federation Fleet in its orbit) and a place of worship for their deified leader, Dark Samus. The Citadel, according to the entry, was built in a matter of weeks. No evidence exists of such a location being programmed into the game.
