HBO announced today that Star Trek: Deep Space Nine costar Alexander Siddig has joined the cast of the upcoming season of Game of Thrones, the massive hit television series based on George R.R. Martin’s ongoing epic fantasy series.

The cable network released this video at their Comic-Con panel in San Diego, which serves as an introduction to several new cast members:





Siddig has been cast in the role of Doran Martell, prince of the land of Dorne and brother of Oberyn Martell (portrayed by actor Pedro Pascal in this past season). Scenes for Dorne will be filmed near Seville in southern Spain; the area will serve to represent the southernmost land in the kingdom of Westeros.

Game of Thrones Season 5 is expected to air in Spring 2015.
