The Korir River is formed by the confluence of the Upper Korir River, the Tpishi River and the Lakusa River west of the Shattered Range in the Mwangi Expanse. It flows through the Screaming Jungle, joins the Pasuango River and empties into into the Lake of Vanished Armies. The River of Lost Tears also flows in the lake. From there the Lower Korir River flows into the Korir River delta and into the sea. The river serves as a trade route between Port Freedom and Kalabuto in Sargava. It also links them to Mzali in the Mwangi Expanse, but foreign traders are unwelcome there.
