From publisher blurb:
A space opera setting
The planet Earth is a distant memory; a myth from our prehistoric past. Humans now occupy a small corner of the Mizendar galaxy, where space is filled with the Aether nebulae, solar-sailing ships, and dozens of alien empires lay claim to nearly every star system known.
Meet the mysterious Syranni, the warlike Zorani, and the enigmatic Machine Empire, all within this galactic guide.
This volume includes and expands on 'Alien Quadrant - Races', but details the entire Mizendar galaxy (more than doubling the page count).
