Great Plain of Tethas

The Great Plain of Tethas, also called the Great Northern Plain, the Plain of Urem, or the Uremite Plain, is a vast expanse of flat grassland and semi-wooded savanna (interspersed with areas of scrub forest or broadleaf forest) that stretches for over two thousand miles across eastern Orithea. Countless long rivers twist and meander across it; the greatest of them all is the mighty Rhanna, into which most of the others flow as tributaries.
As its other names suggest, the Great Plain of Tethas is the dominant geographical feature of the land of Urem. In the past it was divided among many different Uremite kingdoms, but today almost all of it is under the rule of the Kirdan Empire.
