After HBO unveiled the epic Game of Thrones Season 7 trailer today, the show's official Twitter asked fans to tweet out the hashtag #WinterIsHere, along with another emoji. In return, the network would unveil one of 12 new motion posters featuring different characters for this highly-anticipated season, which teases that they are literally turning blue, due to this harsh winter environment (or that the show has switched settings from Westeros to the magical land of Pandora from James Cameron's Avatar movies). Since the latter is quite impossible, it seems these characters must prepare to brave the elements for a long winter ahead.

We have both the motion posters from the Game of Thrones Twitter and the static posters below, which feature Arya Stark (Maisie Williams), Bran Stark (Isaac Hempstead Wright), Brienne of Tarth (Gwendoline Christie), Cersei Lannister (Lena Headey), Daenerys Targaryen (Emilia Clarke), Jamie Lannister (Nikolaj Coster-Waldau), Jon Snow (Kit Harington), Petyr "Littlefinger" Baelish (Aidan Gillen), Sansa Stark (Sophie Turner), Theon Greyjoy (Alfie Allen), Tormund Giantsbane (Kristofer Hivju) and Tyrion Lannister (Peter Dinklage). Unfortunately, these posters don't exactly reveal any new details, except that they're all literally blue in the face, but the trailer that dropped earlier today featured plenty of interesting revelations.

For starters, we only get one brief shot of Bran Stark, but we can see that he now has an actual wheelchair, which we didn't see in any of the other footage of photos released thus far. After Season 1, when he was pushed out of the window by Jamie Lannister, Bran could not walk, and he was mostly carried around by his lovable companion Hodor (Kristian Nairn), sometimes by piggyback, sometimes via a large wooden sled. After Hodor's tear-jerking death last season, his companion Meera (Ellie Kendrick) had to lug him around in that sled on her own, until they ran into Benjen Stark (Joseph Mawle), who had been missing since the first season after going north of The Wall. This brief scene of Bran seems to hint that he is in Winterfell, although that hasn't been confirmed.

Many fans have hoped for a Stark family reunion this season, since the surviving Stark siblings haven't been together since the first season. Jon Snow helped Sansa Stark get rid of the Bolton clan who had taken over Winterfell, with Jon named King in the North after his victory. After spending the past two seasons in Braavos, Arya Stark finally returned to Westeros in the Season 6 finale, killing the nefarious Walder Frey (David Bradley), crossing that name off her death list since he orchestrated the Red Wedding. Still, there is no indication yet that Arya will finally return to her homeland of Winterfell, or that Bran will return home either, but if that happens, it could make for one of the most satisfying family reunions in TV history.

For those who can't get enough of Game of Thrones, the after-show Talk the Thrones has been re-branded this season, streaming live on Twitter and Periscope directly following each episode. The show was originally available through HBO's digital platforms last season, but now the show is moving to Twitter, after the show was ranked as Twitter's top trending TV show last year, while also garnering one of the top 10 hashtags of the year. Take a look at these Game of Thrones Season 7 character posters, to get ready for the Season 7 premiere on Sunday, July 16 at 9 PM ET on HBO.
