There were three sorts of Dornishmen, the first King Daeron had observed. There were the salty Dornishmen who lived along the coasts, the sandy Dornishmen of the deserts and long river valleys, and the stony Dornishmen who made their fastnesses in the passes and heights of the Red Mountains. The salty Domishmen had the most Rhoynish blood, the stony Dornishmen the least. … The salty Dornishmen were lithe and dark, with smooth olive skin and long black hair. The sandy Dornishmen were even darker, their faces burned brown by the hot Dornish sun. They wound long bright scarfs around their helms to ward off sunstroke. The stony Dornishmen were biggest and fairest, sons of the Andals and the First Men, brownhaired or blond, with faces that freckled or burned in the sun instead of browning.
