From the publisher:
Dragon Pass, Land of Thunder illustrates the marvels and wonders of heroic and mythic Kerofinela. Journey from deadly Snake-Pipe Hollow through the Bush Range past impossibly tall Kero Fin, to occupied Boldhome (capital of the Kingdom) and then south into legendary Heortland. Witness the wonders of ancient Kerofinela, birthplace of great Orlanth.
Dragon Pass, Land of Thunder is a supplemental book for the Sartar Rising campaign. It provides maps and information on all of the important places in the land. Many features are described that in the past were only names, and many new places are detailed as well. In addition to many smaller maps, the book comes with a large, full-color map of Sartar drawn by Wesley Quadros under the direction of Greg Stafford. It also includes a complete index, making it the ideal resource for use with other Issaries, Inc. books.
Dragon Pass, Land of Thunder is a must for any narrator running a Sartar campaign, and for any serious fan of Glorantha.
