Obviously, this post consists of spoilers for Game of Thrones, Season 8, Episode 6, "The Iron Throne." We are discussing everything about the series finale, and now you have the opportunity to stop reading and get away from it.
The last moments of the last episode of Game of Thrones brought some big shocks from what the audience had expected. The destruction of King's Landing seems to have led to a better world, albeit not the one some characters have been working towards for years. In the final of the eighth season Westeros progresses not by conquest, but at least by a small piece of democracy. And hey, that's better than Season 1
Episode 6, "The Iron Throne," the last installment of the series, did a lot of post-processing. First and foremost we saw the end of Daenerys Targaryen. After destroying King's Landing, she eventually lost the support of some of her best allies (though not all). Jon asked Dany to show mercy to Tyrion, and when she refused, he took action – killing Daenerys to prevent her from governing the Seven Kingdoms (and beyond) with fear and dragonfire. After her death, Drogon appeared a few seconds later to melt the Iron Throne (which was more symbolic than a meaningful moment, but whatever), and then flew away with Daenerys's body in his claw. Our only clue as to where he was going came later in the episode when it was mentioned that he had been last seen flying east toward Essos, the continent that occupied the cities of Dany and their slavery-freed dragons and Valeryia, the Destroyed, includes land from which Dragon and Targaryen originally came from.
The Immaculata took Jon into custody, but without a leader to tell them what to do with him, they only detained him for a while. Next, they convened a council of Westeros Lords and Ladies in the Dragon's Mine in King's Landing to decide who should lead the Seven Kingdoms and what should happen to Jon and Tyrion. (It contained some familiar faces, including one that was quite brightly lit.) At Tire's suggestion, the most powerful people in Westeros voted for their new monarch: Bran Stark.
In part, Daenerys influence really helped. "break the wheel," ending part of the system of inherited power in the country. Bran ascended to the throne because of his ability as a Three-Eyed Raven he was the smartest among the powerful in Westeros and because of his disability he can not father his own children. That is, if Bran dies, there will be no eldest son to inherit his title, and no one will be forced to live under the thumb of a king just because he was fortunate enough to be born a prince. Instead, the men and women of Westeros will meet again and vote on a new king. It's not a perfect system, of course – the big houses are still great because they have money and land, and they keep that power forever in their families – but at least there's a semblance of a representative democracy in Westeros that it's likely to improve life for ordinary people a little, at least for a while.
Bran immediately named Tyrion, with his new authority, as the king's hand, essentially apologizing for betraying Daenerys. The idea is that Tyrion's betrayal will be a lifelong service, trying to make up for his mistakes in the past by being a good ruler.
Jon looks a little less well. The Immaculate and Sansa Stark are ready to go to war because of their destiny – the Immaculate want justice for their queen, while Sansa wants to save her brother and the man who was once called king to the north. They compromise when Jon is banished back to the wall to rejoin the night watch. It is not a real sentence anymore because there is no night watch anymore. "The world will always need a home for bastards and broken men," Tyrion says of the organization. When Jon arrives at Castle Black, he finds Tormund and the rest of the wildlings and decides to leave the guard and go over the wall with them. You could interpret it as Jon would be king beyond the wall, but it seems much more likely than living his life in freedom with his buddy Ghost.
There is no new king in the north, but there is a queen: Sansa Stark. During the council, Sansa refused to let the north reign from a southern king, even though that king was her brother. Bran allowed the north to maintain its independence, transforming the Seven Kingdoms into six. This makes Westeros technically two countries and not a united one (although one can only wonder how Dorne feels it all, since it has remained quite independent). Who knows how this will change the political situation in Westeros in the future.
Bran formed a new little council with a few critical survivors. With Tyrion as his hand, Ser Davos became his shipmaster, and Bronn of the Blackwater – now Lord of Highgarden, according to his agreement with Tyrion and Jaime Lannister in Season 8, Episode 4 – was named Mintmaster. And although he had not finished his Maester training in the citadel, Samwell Tarly became Grand Maester. Ser Brienne is named Lord Commander of the Kingsguard, and her longtime loyal squire, Podrick Payne, is also knighted and joins the Order.
After things calmed down, Gray Worm and the released Unsullied ships made their way east (probably also with the Dothraki). Gray Worm's target was the Isle of Naath, which recalled his earlier conversation with Missandei in Season 8, Episode 2. The couple had planned what they would do after defeating the Night King and winning the Iron Throne for Daenerys: return to Naath, where the Immaculate would protect the island's peaceful people, Gray Worm said. Although Cersei had Missandei killed, Gray Worm continues the plan to create a home for Naath and protect his people.
Arya Stark, who decided not to return to Winterfell or live her, also got into a ship a life as a highborn woman. Instead, she wants to explore the world by finding out what lies west of Westeros. She mentioned this task while still in Faceless Man training in Braavos. We do not know what might be out there, but if anyone can handle what she finds, it's Arya.
Oh, and Drogon is still out there. Apparently, Bran will use his three-eye raven powers to try to track down the dragon. In any case, dragons still live in the world, and that means there could one day be more of them.
And that was it's. In Westeros, the war is over, and the fate of the people is in the hands of a group that apparently wants to improve life for all. Whether they succeed is literally a different story. As Tyrion Jon said, in 10 years we have to see if the couple made the right decisions.
