River Ivo
From Tar Valon Library
The Ivo is a river in the main continent, located entirely in unclaimed land and flowing from the Black Hills until it joins the Arinelle.
In earlier times, it formed the border between Masenashar and Oburun though it is not clear if it was the border, or if the border merely followed it (TWoRJTWoT, Ch. 11).
