Moebius: The Orb of Celestial Harmony is a video game produced by Origin Systems and designed by Greg Malone. It was originally released in 1985 for the Apple II series of personal computers. Versions were also released for the Amiga, Atari ST, Commodore 64, Macintosh, and MS-DOS. The game is primarily a top-down view tile-based role-playing video game, but it has action-based combat sequences which use a side view, roughly similar to games such as Karateka. Origin Systems produced a sequel to the game, entitled Windwalker.
