Ellaria Sand

Ellaria Sand is a recurring character in the fourth season and is portrayed by Indira Varma. She is the paramour of Prince Oberyn Martell of Dorne and a bastard of House Uller. "Sand" is the surname used for bastards in Dorne.

Season 4
After their arrival in King's Landing, Ellaria and her lover, Prince Oberyn Martell, head to one of Littlefinger's brothels. Oberyn examines three whores while Ellaria lies on the bed, asking her which one she would like. She says that she doesn't want a timid one and he eventually finds one to her liking. When Olyver calls Ellaria "my lady", she calls him out for using a lie to adress her and tells him to call her what she is: a bastard. When Oberyn hears men singing the Rains of Castamere in the next room, Ellaria tries to stop him but can only watch as Oberyn takes out his rage on the Lannister men-at-arms.

Ellaria and Oberyn attend Joffrey's wedding, where she is introduced to Tywin Lannister and Cersei Lannister. Cersei subtly mocks her bastard status, instigating a debate over the cultural differences between the Dornish and the rest of Westeros. She later witnesses the poisoning of King Joffrey.

In the books
In the A Song of Ice and Fire novels, Ellaria Sand is the paramour of Prince Oberyn Martell. She is the bastard daughter of Lord Harmen Uller, the Lord of Hellholt - thus she is one of the "Sandy Dornishmen" of the central desert of Dorne, who possess particularly dark skin, burned brown by the hot desert sun. Her hair and eyes are also black.

Ellaria is the mother of the four youngest of Oberyn's eight bastard daughters, who are all collectively known as the "Sand Snakes". Ellaria's four daughters with Oberyn are named Elia, Obella, Dorea, and Loreza Sand.

She is described as not explicitly beautiful, as she is no longer a young woman and has borne four children, though still attractive and eye-catching, with an exotic, sensuous flair. Like her partner Oberyn, she expresses sexual interest in both women and men. It is not unusual for lords and ladies in Dorne to be openly bisexual, due to the relaxed attitude towards sexuality among the Dornish.
