A major river that flows through Northwest Faerûn.
This river is one of the main routes for trade and commerce in the Sword Coast region. It is cold and deep, nearly a half-mile wide in many places, flowing from the Dancing Falls at the base of the Lost Peaks to the Sea of Swords just south of Waterdeep.
The waters of the Dessarin are home to the silver shalass, a fish that is considered a delicacy across the North.
The Dessarin has three primary bridges: Zundbridge, south of Waterdeep; the Stone Bridge, farther north and east of Red Larch; and Ironford near Womford. It also has the Dead Horse Ford, usable at certain times of the year, east of Yartar.
