The Horn Stream The Time of Troubles & Era of Upheaval Inspired By Ed Greenwood

The Horn Stream is a geographical feature within the fictional Forgotten Realms setting, specifically located in the Dessarin Valley region. It is identified as a tributary of the River Surbrin, joining the larger river system near the major settlement of Yartar. The stream flows generally eastward from the vicinity of the town of Triboar before merging with the Surbrin.

While a canonical map location, the Horn Stream is largely a minor feature, often only listed as a landmark in sourcebooks and adventure modules such as Princes of the Apocalypse. Unlike major rivers in the region like the Dessarin itself, the Horn Stream has little specific lore or history assigned to it in official materials, serving mainly as part of the overall geography that defines the trade routes and wilderness of the North.
