Group shot Game of Thrones season 7 finale trailerHBOThis is an epic group shot.

Warning: Spoilers ahead for the “Game of Thrones” season seven finale.

The first shortened “Game of Thrones” season is about to come to a close with the seventh and final episode airing Sunday, August 27, on HBO. In the teaser video released, we finally get a glimpse of all our favourite heroes congregating in King’s Landing. We’ve broken down the trailer shot-by-shot to see what we can expect on the coming finale (which will be a record-breaking 81 minutes).

Keep reading for a look at all the major reunions heading our way:

The episode opens with Grey Worm and the Unsullied standing in formation outside of King's Landing.

HBO
We've missed you, Grey Worm!

Jaime and Bronn look out at the Unsullied and the Dothraki armies. Even though Daenerys lost some allies, her forces still look formidable.

HBO
We rarely see this side of King's Landing.

They look both impressed and concerned by Daenerys' show of force.

HBO
But this is supposed to be a meeting about a temporary peace treaty.

Cersei has summoned Euron's massive fleet back to Blackwater Bay.

HBO
His fleet is waiting outside of King's Landing.

Meanwhile Tyrion, Varys, and Theon are sailing into the bay, too.

HBO
We haven't seen Theon since he returned to Dragonstone.

Finally, we see the huge group enter the Dragonpit. In the screenshot below you can see Tyrion, Jon, Podrick, Brienne, Davos, Missandei, Jorah, and Theon.

HBO
We're guessing Daenerys is nearby, along with the Hound and Beric.

This means Tyrion, Podrick, and Bronn will all be together for the first time in a while. Plus we might see Missandei and Grey Worm speak outside the castle walls. Also noteworthy is that this is Jon Snow's first time in the capital of Westeros.

Altogether, here's who to expect in the dragonpit scene:

Tyrion, Jaime and Cersei Lannister

Jon Snow

Podrick Payne

Brienne of Tarth

Ser Davos Seaworth

Missandei

Jorah Mormont

Beric Dondarrion

Sandor 'The Hound' Clegane

Gregor 'The Mountain' Clegane (GET HYPE!)

Euron and Theon Greyjoy

Varys

Qyburn

Jon has made this pitch before, so it's likely that he'll take charge.

HBO
He's a pro at informing Westerosi of the coming Night King and his army.

The location for the meeting with Cersei is the ancient Dragonpit of King's Landing.

HBO
Here we see Jon and company entering the arena.

The Dragonpit is mentioned in George R.R. Martin's books as a ruined structure that used to house, you guessed it, dragons.

HBO
There was a domed roof but it collapsed along with the Targaryen reign and their dragons.

This whole buildup and mission was centered around getting Cersei to believe in the Night King's threat.

HBO
We love this new costume Cersei is wearing -- sleek black with stripes and severe shoulders.

Cersei loathes Tyrion, and still wishes him dead. What will their first encounter be like? Based on his expression, things are going to be tense.

HBO
Tyrion distrusts Cersei, but can he predict her every move?

For her part, Cersei is looking smug while Jaime watches her. Will she have some trick up her sleeve, à la the Sept of Baelor explosion?

HBO
This would be a convenient time to wipe out her enemies, but Daenerys' armies would surely take revenge.

We don't see Euron or Daenerys in the promo, but we're betting they will be inside the dragonpit as well. This shot, on the other hand, looks like Theon on a beach.

HBO
Theon told Jon he wanted to rescue Yara, so perhaps we'll see the outcome of that mission in the finale.

Last but not least, the only glimpse of Winterfell was a solitary shot of Sansa walking on the parapets.

HBO
Her tension with Arya and Littlefinger will surely come to blows.

The 'Game of Thrones' season seven finale airs Sunday, August 27 on HBO. In the meantime read look back at the penultimate episode, 'Beyond the Wall,' with our roundup of seven details you might have missed.
