The Sorrowhorn Peaks mark the western boundary of the Roan Valley. The Peaks were once home to the dwarven city of Dorsten but the city, and its inhabitants, vanished during the height of the Race Wars. In the centuries since the citadel vanished, numerous expeditions have been launched to learn the fate of the city, but those few who actually return from their expeditions always return empty handed. It is assumed that since the city vanished nearly overnight that its treasures must still remain within, though no evidence to the truth of that belief has yet to surface. Many travelers passing through the Peaks have reported hearing the famous great horn of the citadel calling out in the night.
