Chronicles of Toril
The Surbrin River is a river in the Silver Marches. It flows from the Spine of the World, after which it is joined by the Rauvin River, and later the Goblintide River, the Laughingflow, and Horn Stream. The Surbrin River then feeds into the Dessarin River.
The town of Nesmé sits on the eastern side of the Surbrin River, with a large fortified bridge across it.
