Avalos

The Great River of Avalon. The Avalos spans the Kor continent from east to west, and is known by other names: Sphahovian, Llangontis, and Great River. 
The River Crescent is a great bend in the Avalos that archs for leagues around Rimwood and the Crescent Plains.
Aelysius is that portion of the Avalos that flows through the southern plains of the Ronic Realms, and in the Saddle Mountains. In the Saddle Vale it is known as Valeriver.
