The Okal Rel Universe is a future where the cultural and biological evolution of the human race has divided it into two societies: "Gelacks" and "Reetions." Gelacks are dominated by the neo-feudal descendants of an ancient bioengineering project that modified humans to tolerate reality skimming, a physically and mentally strenuous method of faster than light space travel which underpins the economy and culture of the Okal Rel Universe. The Reetions are the descendants of unmodified humans whose social system depends upon transparency moderated by a form of artificial intelligence known as arbiters. Each race has advantages and handicaps, physical or cultural. In this official guide by author Lynda Williams, you will discover an ever-increasing treasure trove of information and insight into the Okal Rel Universe.
