From the publisher's website: "The t’skrang call the Serpent River Shivoam, the River Dragon. On the Dragon's broad back they can ride anywhere. From the gates of Throal to the depths of the Servos Jungle, to the treacherous edges of the Mist Swamps, and even into the dark heart of the Blood Wood. The Serpent reaches throughout Barsaive, tying everything together. Mighty t’skrang Riverboats of the t'skrang trading houses, loaded cargo boats, and fishing skiffs of a hundred hinterland villages ply the waters of Barsaive's mightiest river, risking its dangers for profit or adventure. Dangers abound, from hidden currents and swirling rapids over fearsome pirates willing to kill for booty, to the recently established Theran fortress of Triumph near Lake Ban. Nations of Barsaive Volume Two: Serpent River offers gamemasters and players an in-depth look at the Serpent River. Running the entire breadth of Barsaive from the Grand Cataracts in the North to the Mist Swamps in the South, the Serpent River has been used by traders for thousands of years. This book provides detailed descriptions of the six great t’skrang trading houses, featuring revised and updated content, and new material for adventures in the world of Earthdawn. Requires use of the Earthdawn Player’s and Gamemaster’s Guides."
