From publisher blurb:
The barbarians prepare their rebellion! Imperial troops and enemy gods can not crush the Orlanthi.
Thunder Rebels tells what every one of them knows about their land, their gods, and their ways. The men and women worship Orlanth and Ernalda, a great god and goddess whose influences permeate everything.
Thunder Rebels is necessary for anyone who wants to play an Orlanthi hero from the Heortling people of Dragon Pass. It describes their culture, magic, religion, and mythology. Character Generation includes Cultural Keywords, the Eighteen Professions, and almost fifty Subcults of Orlanth and Ernalda. Stories and myths illustrate the people and their deities, and set the stage for the Hero Wars. The Annual Sacred Calendar details the magical holy days of the Heortling year. Maps of Dragon Pass, the Storm Realm, and the Godtime chart the lands of myth and legend.
Thunder Rebels is a supplement for Hero Wars, which you must own to fully use this book. We suggest that it will significantly enhance a narrator's game.
This book is all you need to play an Orlanthi barbarian from Dragon Pass!
