HBO has just released the second trailer for Game of Thrones Season 7, which features a lot of new footage with a few cryptic hints about what's to come, along with loads of action-packed footage. There is a lot to unpack here, and if you aren't caught up with the series quite yet, there will be plenty of SPOILERS below, so read on at your own risk. While we don't get to see who he's talking to, this trailer features dialogue where Jon Snow (Kit Harington) is seeking an alliance, which may be the same one that was teased in the Game of Thrones Season 7 set photos last fall. The trailer ends with quite the cryptic scene that could certainly hint at the death of an iconic character. This is your last chance to avoid SPOILERS, so read on at your own risk.

The trailer debuted on HBO YouTube, which begins with footage of Sansa Stark (Sophie Turner) walking through Winterfell, along with voiceover from Littlefinger (Aidan Gillen), who tells her that she should be fighting every single battle in her head, seemingly grooming her to become a leader. This comes after comments from Sophie Turner where she said Sansa will struggle with the newfound power that Jon Stark now has as King in the North, which could hint that Littlefinger could be pulling the strings to overthrow Jon. While viewers learned that Jon Snow is in fact a true-born Stark, the son of Ned Stark's (Sean Bean) sister and Rhaegar Targaryen, the rest of Westeros still thinks he is Ned Stark's bastard. While we get a brief glimpse of Bran Stark (Isaac Hempstead Wright), whose greensight vision confirmed Jon's lineage in the Season 6 finale, it isn't known when Bran will tell Jon and the rest of his family the truth.

The trailer ends in an even more mysterious fashion, with footage of Jon Snow riding into battle, although we do not see his face, which is coupled with narration of Sansa Stark uttering one of her father's sayings, "When the snows fall and the white winds blow, the lone wolf dies but the pack survives." While Jon Snow is certainly still alive in this trailer, that particular saying coupled with that footage could certainly be an omen that Jon Snow will die, again. After being treacherously murdered by Aliser Thorne (Owen Teale) and several of his Night's Watch brothers at the end of Season 5, Jon Snow was resurrected by Melissandre (Carice Van Houten), although before a critical battle at the end of Season 6, Jon Snow told Melissandre that he did not want her to bring him back to life if he shall die. Jon did in fact survive, ridding the Bolton's from Winterfell and being named King in the North. If Jon does in fact find out that he is a true Stark, it would give him a great claim to the Iron Throne, but the mysterious ending of this trailer could certainly be an omen hinting at his second death.

The trailer is also chocked full of other details, including Jon Snow approaching a fortress gate within a large mountain, although it is never revealed who is on the other side. There is also plenty of footage of Daenerys Targaryen exploring her ancestral homeland of Dragonstone alongside Tyrion Lannister (Peter Dinklage), along with brief shots of Grey Worm (Jacob Anderson) in full armor, Theon Greyjoy (Alfie Allen), Brienne of Tarth (Gwendoline Christie) and Podrick (Daniel Portman) and even The Hound (Rory McCann), along with a number of random battle scenes and brief shots of The Night's King, leader of the White Walker army, Bran Stark and Beric Donadarrion (Richard Dormer), who is seen wielding a sword that magically sets itself ablaze. There is also a number of quick shots, one of which shows Grey Worm and Missandei (Nathalie Emmanuel) continuing their romantic relationship.

With less than a month left until the Game of Thrones Season 7 premiere, airing Sunday, July 16 at 9 PM ET on HBO, it isn't clear how much more footage the network will reveal. It was recently confirmed, though, that press members won't be getting sent early Game of Thrones Season 7 screeners, keeping the policy they set last year intact after the leak of the first four episodes of Season 5. Regardless, take a look at this new trailer for Game of Thrones Season 7.
