A major waterway northwest of Calla Bryn Sturgis that divides into two branches. The western branch, the Devar-Whye, runs close to where the borderlands meet Mid-World-that-was. The eastern branch, the Devar-Tete Whye or Little Whye, divides Calla Bryn Sturgis from the dead lands of Thunderclap. The River Whye runs roughly north-south and serves as an important trade route for the borderland peoples, with lake-boat marts travelling along it. Both branches empty into the South Seas.
