Warning: Spoilers ahead!
Let's start with all the action in the north, since that's what has us the most hyped. Jon Snow will be battling the White Walkers along with a badass crew.
First, there's Beric Dondarrion with his flaming sword. We last saw him with the Hound on season six.
You can see Beric's fiery blade next to Jon in this shot. That's a lot of people — are they wights? Or Wildlings? Maybe a mix of both?
It looks like Jon will re-enact his one-on-one fight with a White Walker on season seven. The last time he did this was in "Hardhome" — the epic season five episode.
It looks like the Hound is traveling north with Jon and Beric to fight, too.
Tormund is there too, fighting alongside Jon and company.
We think this pack of ravens is also in the north — notice all the people beneath them?
This trailer gave us the first look at the Night King in action. He looks upwards at something, but what? Those ravens? Is he in the north where Jon Snow is, too?
Towards the end of the trailer, we see multiple shots focused on Jon, while Sansa recites an iconic Stark line.
"When the snows fall, when the white winds blow, the lone wolf dies, but the pack survives."
That saying is straight from the original book series. Ned says it to Arya as a warning that their family must be united against a common enemy.
Speaking of keeping family together, we think Bran might be finally coming to Winterfell.
You can see Bran and Meera waiting to pass through the gate at the Wall that leads to Castle Black.
And then in this shot of Bran, he's seen in a wheelchair seated in front of a weirwood tree. The man with his back to the camera looks like the same maester who was serving the Boltons in Winterfell.
Maester Wolkan has a similar build, though it's hard to say for certain since we don't see the man's face in the trailer. Regardless — Bran is definitely getting south of the wall and to a place where he'll be given a wheelchair.
Though Brienne was briefly in the first trailer, we finally got a peek at her and Podrick. It's nice to see this duo sticking together.
Jon has a lengthy piece of dialogue: "For centuries, our families fought together against their common enemy, despite their differences. Together, we need to do the same if we're gonna survive, 'cause the enemy is real. It's always been real."
He might be talking to the other Northern lords, since the North is typically united against their enemy, whether that means Targaryens or other threats.
As Jon speaks, we see Daenerys walking through Dragonstone.
Dragonstone is where Stannis Baratheon lived. Daenerys pulls down his banners showing the flaming heart with a stag.
We also get a glimpse of all three dragons — Drogon, Viserion, and Rhaegal — flying over the ocean near Dragonstone.
Daenerys will make this castle her own on season seven.
We know Tyrion will be with her as Hand of the Queen, but both shots of him in the trailer are making us worried.
Tyrion looks worried — and possibly with good cause.
The Greyjoy fleet is headed for King's Landing — you can see the Red Keep in the background. Euron will likely form an alliance with Cersei and aim to attack Daenerys.
Knowing Cersei, she'll be more than amenable to team up with Euron — the biggest bad guy left in Westeros now that Ramsay is dead.
In this snippet we can see Euron himself attacking a ship and looking ready to kill.
This could be bad news for Yara and Theon, who stole the Iron Fleet from Euron and allied themselves with Daenerys.
Theon has been through more torment than nearly any other show character. Will he survive this season?
We believe the shot of a man falling to his knees on a beach is Theon — you can see the typical Ironborn clothing on the man next to a ship.
Meanwhile, Jaime and Bronn will lead the land battle against Daenerys, her dragons, and the Dothraki.
We can't see that going well for him, especially given this fiery and desolate field he's riding through.
Jaime seems determined, though. Will he go head-to-head with Daenerys?
You can just barely make out Daenerys on top of Drogon here, and what looks like Dragonstone in the background. Who is she trying to intimidate, here? Jon? Another unwelcome face on her beach?
Last but not least, there's this mysterious figure whose face is cleverly hidden by the sun. Our first thought was of Arya (and Needle!) but we can't be certain. Maybe it's a flashback of Bran's?
