context_section_description: Tyene Sand (seasons 5–7) portrayed by Rosabell Laurenti Sellers.  Tyene Sand is the daughter of Prince Oberyn Martell by Ellaria Sand. Tyene is fiercer than she looks, especially with her twin daggers. She assists her mother in her plot to assassinate Myrcella Baratheon as revenge against Cersei, whose actions led to Oberyn's death. In the ensuing fight with Jaime Lannister and Bronn, she poisons Bronn by striking him with a poison-coated dagger before they are all arrested. In the cells, she strips in front of Bronn to hasten his heartbeat as well as the poison's effects, though she shows him mercy and gives him the cure. She later synthesises a similar poison for Ellaria, who uses it to poison Myrcella. She gives Ellaria the antidote before she too is killed. When Doran finds out, Tyene kills Areo Hotah while Ellaria stabs Doran in the chest. Tyene subsequently watches her own uncle die without remorse. She is later present when Ellaria meets with Olenna Tyrell to discuss an alliance with Daenerys Targaryen, where she is silenced by Olenna before she can speak. While journeying to Sunspear with her sisters and Ellaria aboard Yara Greyjoy's ship, Tyene is captured by Euron Greyjoy while defending her mother and taken as a captive aboard his flagship, Silence. Given as a gift to Cersei, Tyene is chained with her mother in a dungeon. Cersei uses a version of the poison on Tyene and leaves her chained in front of her mother so that Ellaria can watch her daughter not just die but decompose.
  Nymeria Sand (seasons 5–7) portrayed by Jessica Henwick.  Nym Sand is the second eldest of Prince Oberyn's bastard daughters. Her mother was an Eastern noblewoman who brought Nym up to be cultured, graceful and deadly with a whip. She assists Ellaria Sand in her plot to assassinate Myrcella Baratheon as revenge against Cersei Lannister, whose actions led to Oberyn's death. Though she is briefly imprisoned by her uncle Doran for her treachery, Ellaria murders Myrcella, and Nym joins her in her coup by ambushing and murdering Trystane Martell. She is later present when Ellaria meets with Olenna Tyrell to discuss an alliance with Daenerys Targaryen, where she is silenced by Olenna. In Season 7, Nymeria accompanies Ellaria, Yara and Theon Greyjoy, and her sisters on the journey to Sunspear from Dragonstone. After they are ambushed by Euron Greyjoy and his fleet, both Nymeria and Obara confront Euron while Tyene protects Ellaria. After the Lord Reaper of the Iron Islands kills Obara, an enraged Nymeria attacks him with her whip, only to be choked to death and then hung from the prow of the ship with her weapon, next to her sister.
  Obara Sand (seasons 5–7) portrayed by Keisha Castle-Hughes. A fearsome warrior, Obara Sand is the eldest bastard daughter of Prince Oberyn Martell. Her mother was a Dornish peasant girl who caught the eye of the Prince. She assists Ellaria Sand in her plot to kill Myrcella Baratheon as revenge against Cersei Lannister, whose actions led to Oberyn's death. Though she is briefly imprisoned by her uncle Doran for her treachery, Ellaria kills Myrcella, and Obara joins her in her coup by personally murdering Trystane Martell, her own cousin. She is later present when Ellaria meets with Olenna Tyrell to discuss an alliance with Daenerys Targaryen, where she is silenced by Olenna. In Season 7, Obaara accompanies Ellaria, Yara and Theon Greyjoy, and her sisters on the journey to Sunspear from Dragonstone. After they are ambushed by Euron Greyjoy and his fleet, both Nymeria and Obara confront Euron while Tyene protects Ellaria.

She is impaled at the front of the ship with her spear, next to her hanging sister, Nymeria.
