River of Lost Tears

From PathfinderWiki

The River of Lost Tears rises in the Bandu Hills, and flows via Fort Bandu, Stark Point and Kalabuto into the Lake of Vanished Armies.

It forms the border in that region between Sargava and the Mwangi Expanse. The garrison of Fort Bandu are attempting to build a bridge across the river, but so far this has been thwarted by attacks from the local Bandu tribe.1
