West Sellen River
The West Sellen River is part of the vast Sellen River system but is, in itself, a long and important river forming the boundaries between nations for its entire 1,200-mile length.
South of Lake Laruba, the River Kingdoms form the eastern bank of the West Sellen River. In this phase the river is joined by its tributary, the Twinetongue River. Eventually, the border of Ustalav turns westward and the river now becomes the border between Razmiran and the River Kingdoms, as the river continues southwards.
