Description of Obara Sand ("Sand Snake"):

Obara Sand is the illegitimate daughter of Oberyn Martell and an Oldtown courtesan. She is the eldest of the infamous Sand Snakes. Obara is a big-boned woman near to thirty, long-legged, with close-set eyes and with the same rat-brown hair of her mother which she sometimes ties in a knot. She strides quickly and angrily. Obara has callused hands and can have a mannish look.
