The River Keld is located in central Avistan, flowing from its source in the Aspodell Mountains in a westerly direction before meeting up with the River Iseld and flowing into the Inner Sea. Its source is located near the point where Isger, Cheliax, and Andoran meeet, and for much of its early journey, the river forms the border between the first two countries. It flows past the blackened remains of the Chitterwood following the foothills of the Aspodell. Once it joins the Iseld past the Chelaxian town of Misarias, it is wholly within the latter country, bisecting the Whisper Woods.
