The second volume of the Encyclopédie Galactique covers the following topics:
- Day-to-day life in the Galactic Empire, with articles describing the Imperial Justice, trading (and black market), communications, imperial culture (including sports and games)
- the different Guilds (Imperial Army, Merchants Hanse, Navyborg guild...), with rules for a character's career in her guild of choice
- Skills, with new skills, rules about teaching, psychic powers, and a set of optional rules to add Perks and disadvantages to characters
The last part of the encyclopedia features two scenarios. The first ("Cas de conscience") has the players explore an uncharted world on behalf of the B.A.I. ("Bureau des Affaires Indigènes", native affairs bureau). The second one ("Le Kerl de Mélancol") puts the players in charge of finding and protecting the successor of the late Imperial religious advisor.
