Grayflow

The Grayflow was a river found in the western end of the Savage Frontier in northwest Faerûn.

Geography
Emerging from the Graypeak Mountains, it ran northward toward Llorkh, before veering west. It was joined by the river Loagrann south of Orlbar, and then flowed into the Delimbiyr river with a confluence at Loudwater.

Together, the Grayflow and the Loagrann drained the lands of the Greyvale.
