River Thay was a large, sprawling river that served as a major thoroughfare for the movement of goods and people across northern Thay. It flowed from Lake Thalimbrar atop the Thayan Plateau, served as the border between Eltabbar and Delhumide, flowed down the northern cliff face of the First Escarpment and into Lake Mulsantir and the Surmarsh.
