The final countdown is on, with only one single episode left until Game of Thrones is done forever. But we don’t have to say goodbye just yet — we can at least wait until the end of the month when HBO releases Game of Thrones: The Last Watch.

The two-hour documentary from director Jeanie Finlay says farewell to Westeros with a BTS look at the green screens, the costumes, the makeup, the sets, the night shoots, and all of the hard work it took to build the fantasy world that fans fell in love with.

The Last Watch debuts on HBO on May 26. Get a sneak peek below.
