The fourth of Greg Stafford's pre-finished works. Unlike the other books, this is summary, non-Glorantha-world information. Like them, however, it is a non-professional publication.

This book is the lost half of the Glorantha: Genertela, Crucible of the Hero Wars box from Avalon Hill. It includes all the info on the oceans and islands and the Pamaltelan continent. Some of the maps are a bit rough and incomplete, but otherwise it's a very complete reference for the rest of Glorantha.
