From the Back of the Book: In the far future, mankind has scattered to many worlds and divided into many races... and some are very alien, despite their Human ancestry. GURPS Traveller: Humaniti describes 16 Human-descended races from the far reaches of the Imperium and beyond, including the technologically advanced Darrians (with their sun-smashing Star Trigger), the carnivorous Dynchia, the dour warrior Azhanti, and the agressive Itharians.
