River Waeth

The River Waeth, sometimes Waith, is a major tributary of the Helvander. Its headwaters are on the south-facing slopes of the Adhemars' easternmost ranges. Its upper course flows down through the highlands of Baltusraal, then it turns south and runs through Ceregar and Qyrsh before joining the Helvander in northern Yenris. The city of Qyrsh, astride the lower Waeth, has historically controlled the river trade that moves upon it, and grown rich thereby. 
The Waeth flows through and gives its name to the Waethwood, a sizable expanse of forest located mostly in southern Ceregar.
