Omega 99
Ten years after Moonbase Omega opens as a center for research and diplomacy, national interests bring spies, military personnel, and political conflict to the Moon. An explosion at an FTL research station tears Luna from its orbit and sends it into an unfamiliar region of space, amid warring aliens and mysterious machines. This science-fiction campaign setting for Cepheus Engine and other 2D6-based roleplaying games details the Moon, its human inhabitants and technology, nearby alien civilizations, and the space within six parsecs of Luna’s new location. It also includes adventure seeds for stories about Earth’s first explorers in a runaway Moon.
