The Tourondel River runs west to east forming the border between the nations of Nirmathas and Lastwall, and splitting the Fangwood Forest into its northern and southern portions. It begins high in the central Mindspin Mountains of Varisia east of Janderhoff and flows east into Nirmathas where it is joined by the Shining River north of Marching Springs. After passing the Lastwall settlement of Roslar's Coffer, it flows into the Fangwood, passing the Nirmathi town of Kassen and Three Pines Ford in Lastwall. It eventually spills into Lake Encarthan between the towns of Tamran and Vellumis, with Crowstump near its mouth.
