Ugly, brutish, malevolent and in service to dark powers: the uz of Glorantha have a bad reputation which is all too well deserved. The Guide to Trolls presents everything Games Masters need to present these brutes as detailed enemies in Glorantha campaigns, as well as including the necessary lore for players to portray uz characters themselves, seeing how it feels to play the 'other side' of things.

Included are expanded details on uz culture and physiology, regional differences between the trolls, as well as including new rules for troll magic: rituals to appease their dark gods and the magic of the uz cults that revere many of the most sinister deities ever to walk the face of the world during the Godtime.
