From the back cover:
Viewed with fear by other races, the Zhodani are believed to harbour powerful psionics within a terrible and oppressive society. Alien Module 4: Zhodani peels back the layers of mystery and mis-information to reveal a fascinating race who are a domineering force in their region of the galaxy.
This book is packed with information for both players and referees. New rules for careers allow players to create their Zhodani characters, which are then well served by technology and ships designed by and for the Zhodani. Chapters are devoted to playing a Zhodani and how their society and culture are structured, complete with how they handle psionics. Finally, we have also included a complete new sector to explore, meshing seamlessly with the Spinward Marches.
