The Rhivi Plain was a large plain in the center of north Genabackis. To the north of Pale, it was flat and yellow-grassed. The plain was mainly composed of grassland and its centre was home to the nomadic Rhivi culture. The Rhivi Trail ran from the city of Pale north, through the plain to Patch. The Plain was surrounded on three sides (west, east and south) by mountain ranges including the Barghast Range, the Tahlyn Mountains and the Moranth Mountains and forestland. The Rhivi Plain had once been the site of an ancient inland sea that had ultimately withdrawn to the borders of Lake Azur.
