Hardcore warriors give birth to hardcore offspring: In this latest Game of Thrones featurette from HBO, we get to meet Oberyn Martell's (RIP, man) three daughters who are collectively known as the Sand Snakes. The video is a close look at how weapons master Tommy Dunne handcrafted the Dornish weaponry for Season 5. 

While the daughters—Obara (Keisha Castle-Hughes), Nymeria Sand (Jessica Henwick) and Tyene (Rosabell Laurenti Sellers)—are actually the bastard daughters of Martell and his paramour Ellaria Sand HBO has pared down minor details for smooth storytelling's sake. Obara's weapon of choice matches her father's: the spear. Nymeria prefers the whip while Tyene opts for the double daggers. Looks like these girls are just as beautiful and lethal as their parents are (...were).

On top of all that, the Sand Snakes, much like many of the other characters on Game of Thrones, are probably pretty angry at this point. Non-book readers' interests are piqued, however: Why is HBO dedicating this featurette to them? Perhaps the three will play a big role in the upcoming season. 

Game of Thrones returns to HBO on Sunday, April 12.
