“Game of Thrones” returned to HBO briefly on Sunday. The network released the first official teaser for Season 7 of the original series during a brand new episode of “Westworld.”

The brief clip — comprised of several still images — gave little away about what’s to come when the show premieres in 2017. It featured Sansa Stark (Sophie Turner), Arya Stark (Maisie Williams) and Jon Snow (Kit Harington). The images lead many “Game of Thrones” fans to believe Season 7 will center around House Stark, though Bran (Isaac Hempstead Wright) was not shown.

In the teaser Sansa can be seen standing before the weirwood tree, located in Winterfell. In the still she appears shocked or frightened, though it is not clear what she’s looking out at. Arya has a similar expression on her face as she sits atop a horse wearing all black. The shot is taken from a low angle, giving nothing away about her location with the background. Lastly, Jon is shown in conversation with a women. There has been some speculation among Thronies that he is talking to Sansa, though it is not clear from the image. The teaser did not reveal the date on which “Game of Thrones” fans should expect the show to return.

While there have been a number of spoilers leaked, much of the Season 7 plot remains a mystery. On Nov. 20, El Periodica Extremadura was able to snag photos from a “Game of Thrones” set in Barrueco de Arriba, Spain. The pictures showed the Dothraki army — currently lead by Daenerys Targaryen (Emilia Clarke) — carrying out a large scale attack on unsuspecting caravans. Only the actors portraying the Dothraki soldiers were present during the shoot, which lead the site to speculate that the horses and people operating the caravans will be added later. Due to their absence, it is not clear who the caravans belong to, but El Periodica Extremadura noted that they were seen during an earlier shoot leaving Highgarden.

Spanish-language spoiler site Los Siete Reinos confirmed days earlier that the Lannisters were scene marching with the caravans from Highgarden. Jaime (Nikolaj Coster-Waldau) and Bronn (Jerome Flynn) were scene on set by onlookers nearby. Los Siete Reinos reported that it did not seem that Daenerys would be present during the attack carried out by her men. Clarke was reportedly filming scenes in Belfast, Ireland, when the sneak attack was filmed. The scene had not yet wrapped when the report was published, however, which left time for her to potentially return.

A potential Lannister takedown isn’t the only thing that’s got fans on the edge of their seats, anxiously awaiting the “Game of Thrones” Season 7 premiere. Rumors of the Stark children reuniting, Jon and Daenerys joining forces and some serious White Walker drama have also been circulating. Fans in Spain spotted the King of the North and Mother of Dragons chatting cliffside in an area some speculate will be portrayed as Dragonstone — a former Targaryen stronghold.

Since then it’s been reported that the two will find themselves in Kings Landing, where they’ll be joined by Gendry (Joe Dempsie) and a few other fan favorites. While there, Jon will attempt to convince the people of the Seven Kingdoms about the very real threat the White Walkers pose to them. They’ll doubt him, as many have before, prompting him to bring a member of the undead army before the court in the Dragonpit. Watchers on the Wall, a reliable “Game of Thrones” spoiler group, confirmed that the scene was being filmed in Seville, Spain.

“Game of Thrones” is expected to return in the summer of 2017. There is no official word on a release date at this time.
