The Magnificent Westeros Seven, the Fellowship of the Wight, the Suicide Squad — whatever your preferred nickname, the group led by Jon Snow is going to face a seemingly impossible task in this week's "Game of Thrones."

HBO released the photos for Season 7, Episode 6, "Beyond the Wall." They don't reveal much about Jon and company's time in the North, though we can probably assume a pretty big battle. This is, after all, the penultimate episode of the season, when most of the huge showdowns have happened (see: "Battle of the Bastards," "Blackwater").

So, here are some pensive portraits of several of the gang, starting the King in the North:

Jorah Mormont:

Tormund:

Beric Dondarrio and Jon:

And there are a few action shots, including one of Beric with a flaming sword!

Whatever goes down beyond the Wall, things are still percolating over in Winterfell. Last we saw, Littlefinger had set up Arya to find a letter that Sansa had written in Season 1, pleading with Robb to bend the knee to Joffrey. Will Arya fall for it? Will it drive the sisters further apart?

Wonder what Sansa is reading here? Let's hope whatever is, Brienne can provide wise counsel:

And in Dragonstone, all of Daenerys' boyfriends advisors left for the North. Here, she walks with her Hand, Tyrion, as her dragons look on:

And we're burning with curiosity about this fireside chat. Let's hope Tyrion is giving better advice to Daenerys than he has so far this season.

"Game of Thrones" airs Sundays at 9 p.m. on HBO.
