A character/reference from the PS2 game series "Xenosaga".

Fifth Jerusalem is the current capital planet of the Galaxy Federation, and seat of the central legislative judicial, and administrative agencies. The headquarters of the S.O.C.E. is also located here. Its name originated from the fact that it is the Fifth capital of the Galaxy Federation. In the game, the long-forgotten Earth is referred to as Lost Jerusalem. "Fifth Jerusalem" also encompasses a large administrative space-station in orbit around the habitable world of the same name. Most of the administration appears to go on onboard the space station.
