Fan Casting Oberyn Martell in A Song of Ice and Fire

Oberyn has the features of a salty Dornishmen. He is a tall, slender, graceful, and fit man, and has a lined and saturnine face with thin eyebrows, black "viper" eyes and a sharp nose. His hair is lustrous and black with only a few silver streaks and recedes from his brow into a widow's peak.
