Dorne

Dorne is the large peninsula which makes up the southernmost part of Westeros and is one of the constituent regions of the Seven Kingdoms. The lords of the ruling House Nymeros Martell style themselves "Prince" and "Princess" in the Rhoynish fashion.

Geography
Dorne is the hottest region of Westeros. The region is rocky, mountainous, arid and dry, and features the only desert on the continent. 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 stormlands to the north and the Reach to the northwest and west. There are two major passes, the Boneway and the Prince's Pass, which go through the Red Mountains to the Dornish Marches of the stormlands. The Prince's Pass leads to Nightsong, while the Boneway leads to Summerhall.[3] Sunspear and the Water Gardens, both controlled by the ruling House Martell, are located in southeastern Dorne.

Most of Dorne south of the Red Mountains is an arid wasteland. Eastern Dorne largely consists of dry, stony soil ill-suited for agriculture, while western Dorne contains deserts of red and white sand. The lords of House Vaith, for instance, are known as the Lords of the Red Dunes, while nobles of old who settled desert oases called themselves the Lords of the Wells. Sand dogs live in the desert.

The major Dornish river is the Greenblood in southeastern Dorne, which is formed by the Vaith and the Scourge near Godsgrace. The trading port called Planky Town is located at the mouth of the Greenblood along the Summer Sea. The Brimstone in southern Dorne flows past the Hellholt to the Summer Sea. The Torentine has its source in the Red Mountains of western Dorne and ends at Starfall along the Summer Sea. The Wyl flows across the Boneway in northern Dorne to the Sea of Dorne. There is another river in northern Dorne which flows near Yronwood to the Sea of Dorne, but its name is as yet unknown.

The southern coast is some four hundred leagues long. It is ridden with cliffs, whirlpools, and hidden shoals, with few safe landings.

People
Dorne is the least populous of the Seven Kingdoms. Dornishmen differ both culturally and ethnically from other Westerosi due to the historical mass immigration of Rhoynish people and their relative isolation. Dornishmen have adopted many Rhoynish customs on top of their First Men and Andal origins. Dornishmen have a reputation for hot-bloodedness and sexual licentiousness and are still viewed with some mistrust and rivalry by the people of the neighbouring Dornish Marches and the Reach. Dornish bastards of noble origin are given the surname Sand. Dornish paint their silks instead of sewing coats of arms.

Dorne contains septs for the Faith of the Seven and red temples for followers of R'hllor.
