Following tonight's episode of HBO's Game of Thrones, the network released a brief preview for next week's Season 6 finale, The Winds of Winter, airing Sunday, June 26 at 9 PM ET. Tonight's epic episode Battle of the Bastards set the stage for quite the momentous season finale, but if you haven't seen it yet, there will be plenty of SPOILERS below, so read on at your own risk. While there is still very little we know about the finale, this teaser sets up a number of important plot points.

Tonight's Battle of the Bastards represented the biggest single battle in the show's history, and possibly even the history of television itself. Jon Snow (Kit Harington), Sansa Stark (Sophie Turner) and their allies squared off against the nefarious Ramsay Bolton (Iwan Rheon) to take back control of Winterfell. While it looked like the Bolton forces were easily overtaking Snow's men at first, Petyr "Littlefinger" Baelish (Aiden Gillan) finally returned, bringing the Knights of the Vale with him as the tide finally turned, resulting in Ramsay's defeat and his particularly gruesome death, by his own hounds.

This season finale trailer shows Jon Snow telling Sansa Stark that they must stick together, because they have plenty of enemies now, some of whom we also get to see. Walder Frey (David Bradley) is seen toasting with Jaime Lannister (Nikolaj Coster-Waldau), teasing that "the Frey's and Lannisters send their regards." Of course, longtime fans of the show know that "the Lannister's send their regards" is what Roose Bolton (Michael McElhatton) said to Robb Stark (Richard Madden) before killing him at the Red Wedding, so perhaps the Frey's and Lannister's are planning another slaughter.

We also see Sansa Stark asking Littlefinger what he wants, although Littlefinger adds that he thought she knew what he wants. Now that Sansa and Jon control Winterfell, we'll have to wait and see if any of their enemies make a play to take Winterfell. We also see Davos Seaworth (Liam Cunningham) furious with Melisandre (Carice Van Houten), presumably after learning what really happened to Stannis Baratheon's daughter, Shireen (Kerry Ingram). We saw in tonight's episode that Davos found one of Shireen's burnt dolls, after she was burned alive as a sacrifice to the Lord of Light.

We also see that the High Sparrow gets prepared for the trial of Cersei Lannister (Lena Headey), Margaery Tyrell (Natalie Dormer) and Loras Tyrell (Finn Jones). We also see Daenerys (Emilia Clarke) embracing Daario Naharis (Michiel Huisman), along with a brief glimpse at Bran Stark (Isaac Hempstead Wright), but there is still very little we know about the finale. Take a look at this preview below and stay tuned for more on this highly-anticipated episode.
