From publisher blurb: This is a supplement for use with Cepheus Engine and/or the Frontiers of Space. Space travel is a lonely occupation. Vast expanses of space are totally uninhabited. The great distances between populated worlds makes meeting other intelligent life forms during space travel a rare occurrence. But when such meetings take place..... the fun begins..... This is a comprehensive system of encounter tables for use with Cepheus Engine. The tables are designed for the Frontiers of Space (Sonora Sector) but can be used in any Cepheus Engine game or campaign.
