River Sur

This river forms part of Thay’s northern border with Thesk. Narrow and swift at its origin, a spring located along the top of the First Escarpment, the Sur slows and widens rapidly, becoming wide, shallow, and infested with disease-carrying insects as it flows past the Surmarsh, finally emptying into Lake Mulsantir. Despite its proximity to Thay, the Red Wizards have little influence over the Sur and its environs, though vessels from Surthay periodically sail here to fish.
