D O R N E →large peninsula which makes up the southern-most part of Westeros, and is one constituent regions of the Seven Kingdoms. Its capital is Sunspear and the lords of the ruling House Martell still style themselves “Prince” and “Princess” in the Rhoynish fashion.
Dorne is bordered by the Sea of Dorne to the north, the islands known as the Stepstones to the east, and the Summer Sea to the south. Stretched between them is the mountain range known as the Red Mountains, which separates Dorne from the remainder of the Seven Kingdoms by land. There are only two major passes though the Red Mountains, connecting Dorne with the rest of the continent by land, the Stone Way Pass and the Prince’s Pass. The Prince’s Pass leads to the Reach, while the Boneway exits the mountains near Summerhall.
Dorne is the hottest region on Westeros. The region is rocky, mountainous, arid and dry, and features the only desert on the continent. Its rivers provide some fertile lands and even during a long summer there is enough rain and other supplies of water to keep Dorne habitable. Inland water is almost as valuable as gold, and wells are jealously guarded.
