From the back cover:
Cults of Prax is RuneQuest's first major supplement, and it explores the dominant religions in a particular area of Genertela more closely than was possible to do before, beginning with the most primitive ancestor warship, passing though the tribal deities of the simple nomad barbarians, and exploring the intricacies of the more civilized Lightbringer cults with trader deities and a god of knowledge. Though all cults receive a broad range of capabilities from their divine relationships, there are some deities specializing in certain activities and areas, such as a war god, a city god, and the mysterious Lunar cult. Finally there are religions of non-human races including the elf cult and two troll cults.
