'Game of Thrones' Season 7 News & Updates: Euron Geryjoy Defeats Sand Snakes? Leaked New Photos; A Grand Alliance Being Plotted?

A new set of production pictures of Game of Thrones season 7 has leaked and it looks like there would be a big alliance brewing. And Cersei (Lena Heady) has been looking more wicked and badass as more than ever.

The Lannister-centric images from the production set in Spain's Los Barruecos National Parks show that there would be some huge story circulating around the villain Euron Greyjoy (Pilou Asbaæk), his defiant niece Yara Greyjoy (Gemma Whelan), and two Dornish prisoners who seem to be familiar.

The pictures show that Euron arrives on horseback to a rainy King's Landing with his niece Yara, Ellaria (Indira Varma) and Tyene (Rosabell Laurenti Sellers) in tow. They are his captives and it confirms a rumor that Euron will be successful in a sea-battle that would kill the Sand Snakes. With no presence of Obra (Keisha Castle-Hughes) or Nymeria (Jessica Henwick), they are presumed to have been wounded by Euron's sword.

But where is Cersei? She had been filming in Dubrovnik, Croatia with The Mountain (Hafthor Bjornsson). The location was used to describe the look of the King's Landing at its best. Even though it has been used for the previous seasons, the use of it for season seven is still hazy to fans.

The city was used extensively for the filming of Battle of the Blackwater because of its majestic and well-preserved nature of the walls, which is a good description in the book. Would there be another battle in the King's Landing?

But what is more striking in Cersei is her pumped up villainous look. In the photo, she is clad in all black with a dark gold neckpiece and shoulders.

Don't feel too bad for them, though - if Euron's plan is indeed to present these three women to Cersei Lannister (Lena Headey), there's a very good chance a much worse fate awaits them.

More striking is Cersei's new, more villainous look: all black, with a dark gold neckpiece and shoulders. While this is how we see her at the end of season 6, her guards have been decked out in slick-but-evil-looking duds as well: black armor with silver shoulders and an emblem of the crown emblazoned on their chest plates.
