Ellaria Sand is the paramour of Price Oberyn Martell. She assumes the last name Sand as she is bastard-born of a noble house, much the way Snow is the bastard name given in the North. Ellaria traveled to King’s Landing with Oberyn for Joffrey’s royal wedding, where Oberyn was ultimately killed in trial by combat. After the death of her lover, Oberyn, she is intent upon avenging his death.
