From the publisher's website:
Stars of Inequity is a supplement for Rogue Trader that presents tempting new opportunities for those brave few who make their livings in the Koronus Expanse.
This detailed resource focuses on the perilous worlds of the Expanse. Game Masters can create their own new realms with the World Generator, a system designed to craft unique planets filled with terrible risks and unmatched potential for profit. Players can brave the dangers of planetside missions, crossing the surface of shadowy worlds to explore deadly jungles, ancient ruins, crashed voidships, and more. And with the Colony Creation rules, your group can construct, expand, and control its own outposts on the lost and forgotten worlds of the Expanse!
