The River Whye is located Northwest of Calla Bryn Sturgis, the main setting of Wolves of the Calla. The River is divided into two sepearate branches. The Devar Whye branch extends up to where Mid-World meets the Borderlands. The eastern branch known as the Devar-Tete Whye divides the Borderlands from the dead lands of Thunderclap beyond.
An important trade river of the Borderlands region, both ranches of the Whye empty into the South Seas.
