Orithea

Orithea is one of the four continents of Urva, situated mostly in the northwestern hemisphere. Although considered a continent in and of itself by common convention, geographically, Orithea is the central portion of the supercontinent Umre, which also comprises the continental-sized landmasses of Thelbiron (to the north of Orithea) and Ulthark (to the south).
Geography
The northern and western interior parts of Orithea are mostly dominated by a series of arid endorheic basins separated by high, jagged mountain ranges, many of them volcanically active. Collectively, this vast expanse of harsh and barren terrain is referred to as the Kesh Karkhan., although it encompasses many distinct regions and differentiated geographical features. To the south, the Kesh Karkhan gives way to the high plains of the Suagir steppe; to the east, to the more fertile and low-lying Plain of Tethas, drained by the great River Rhanna. Further south still from the Suagir steppe lies the broad forested lowland expanse known as Kelimaria, and from there the terrain rises again, into a series of mountain ranges and elevated plateaus that dominate the lands of Vastemar and Sularia. These regions mark the southernmost edge of the continent; at their southern extent, where the mountains again slope down to rolling savannah, Orithea ends and Ulthark begins. 
The far nothwestern parts of Orithea, across the arid interior from the steppes of Suagirea, are the regions known as Enyrion and Khadoa. They are mostly characterized by a mix of rich, green lowlands and gently rolling hills. Extending westwards and southwards from this region are the Western Isles, a series of extensive island chains that spread out into the Encircling Ocean off Orithea's west coast; the largest of these islands, Azhir, is nearly 1,500 miles long from tip to tip. In the northeast, where Orithea meets Thelbiron, high mountain chains run up from the basin-and-range country of the interior to form a steep, rocky spine for the land bridge joining the two continents. 
From the southeastern part of Orithea extends Rhydain, a subcontinental-sized peninsular landmass with a mostly mountainous topography that stretches roughly two thousand miles east to west. Though geographically part of Orithea, Rhydain has long been considered a distinct region, so it is common to hear reference to "Orithea and Rhydain" as paired, but separate, places. Separated from Rhydain's eastern tip by a narrow strait is the western end of the large island Taijuria. Between Rhydain, Taijuria's northern shores, and the southeastern coast of Orithea proper lie the Sarpic Seas, which ultimately connect to the Thurnic Ocean in the east. Rhydain's southern shores lie on the Emerald Ocean.
