From publisher blurb: Now’s your chance to explore the final sectors of Ephemeris “Near Space.” You’ll learn about the colonies that have been established, the worlds that are waiting to be colonized, and the other oddities that populate these six sectors. Learn about planets that once held civilizations, and no longer do, or learn about hyperspace rifts created by a war of Cyber Wizards, or learn about the asteroid obstacle course that the Althani have created. These are just a few of the things waiting for you in The Ephemeris Encyclopedia Galactica: Sectors Fifteen-Twenty.
