Keisha will be one of the show's new stars when the fifth season of Game of Thrones starts airing on April 12. She plays Obara Sand, the eldest daughter of season 4 character Oberyn Martell.
She'll be joined by on-screen sisters Tyene Sand and Nymeria Sand (played by Rosabell Laurenti Sellers and Jessica Henwick) as the deadly 'Sand Snakes' of Dorne, one of the fictional kingdoms in the Game of Thrones universe.
The role calls for Keisha to show off some action skills, as her character Obara is described as a strong fighter!
Fans got a closer look at the Sand Snakes and their weapons last week, when HBO released a new video showing Keisha in full warrior costume as Obara Sand. Check it out here.
