From the Traveller universe, this book covers two major races — the psionic human Zhodani, and the canine Vargr — and three minor races from Zhodani and Vargr territory — the saurian Drakarans, the arachnoid Clotho, and the gas giant manta-like Sheol.

Character templates, technology and deckplans are given for each race, as well as details of the major races' history and geography. A chapter on Zhodani psionics finishes the book off.
