Now it's a party! Somehow, we've already reached the final episode of "Game of Thrones" Season 7, and it will bring together almost everyone in the Seven Kingdoms.

The Season 7 finale, Episode 7, airs Sunday, August 27 on HBO. It's an 80-minute episode, and it reportedly the emotional Episode 6, "Beyond the Wall."

In the finale promo, we see a gigantic meeting of the minds from across Westeros in the Dragonpit in King's Landing. This is where Jon Snow will try to convince Team Cersei to declare a truce with Team Dany and forces to defeat the White Walker threat.

Jon Snow: "There is only one war that matters. And it is here."

We also revisit Grey Worm, who has been stuck at Casterly Rock all season. And it looks like things have not warmed for Sansa Stark up at Winterfell. She sent Brienne as her envoy to the Dragonpit meeting, so she could stay behind and deal with the Arya/Littlefinger situation.

reportedly start filming in October 2017 and air in either 2018 or (let's hope it doesn't come to this) 2019.
