It’s the first official photos of the Sand Snakes! Game of Thrones season 5 introduces a trio of deadly young women, all half-sisters from Dorne with the same powerful father (last season’s philandering, doomed Prince Oberyn Martell). What do they want? Revenge, of course! (They’re from Dorne, remember?) “It’s fun because they’re constantly fighting, but it’s the kind of family that if an outsider comes in, they all band together and unify,” says showrunner David Benioff, who cast actresses of different nationalities for the roles who all still manage to pass as siblings.

There’s the eldest, Obara (Keisha Castle-Hughes, a Kiwi whose character takes after her dad by fighting with a spear), Nymeria (Jessica Henwick, a Brit who wields a bullwhip) and the youngest, crop-topped Tyene (Rosabell Laurenti Sellers, an Italian- American who gets stabby with double daggers). “We haven’t seen women like this on Game of Thrones before,” observes Castle-Hughes. “You have lone wolves like Arya and Brienne, and others like Daenerys or Cersei, who are politically strong surrounded by men. But you haven’t seen women who are strong together and who collaborate — which is a dangerous thing. We’re three girls who are violent and manipulative who are thirsty for Lannister blood.” (You know, if you guys ever leave Dorne, you should really look up this girl named Arya…).
