In the fantasy roleplaying world of Glorantha, magic works because relations between the spiritual and physical planes are firm and immediate. Maintaining good ties with your chosen god allows your character to learn special magics or to receive visions of other places, provides him with trusty companions in a cut-throat world, and may even give him the chance for divine intervention to escape a tight spot. In many ways Glorantha has a depth and consistency unparalleled in gaming.This major supplement explores religions useful in and designed for fantasy settings. Starting with the most primitive ancestor worship, the book progresses through tribal deities of nomadic barbarians, the intricacies of more civilized cults, and the horrors of chaos.

Non-human religions include an elf cult and numerous troll cults.This book offers over 100 Rune and Battle magic spells and skills not in the standard rules, handy for the gamer intent on long-living characters.
