We also see Unsullied and Dothraki warriors riding together, Arya Stark (Maisie Williams) riding through snow, and plenty of the intense dragon-centric action the cast and creators have been promising all these months.
But it's Ser Davos Seaworth (Liam Cunningham) who steals the show with the line: "If we don't put aside our enmities we will die. Then it doesn't matter whose skeleton sits on the Iron Throne."
As a reminder of what he's referring to, HBO released this motion poster on Twitter ahead of the trailer:
The official date for the premiere of Game of Thrones season seven on HBO in the USA is July 17.
The release date was previously announced in a time-honoured although not very time-efficient tradition via an ice block and a couple of flame throwers.
Sky Television will simulcast the show on SoHo for Kiwi viewers, and episodes will be made available on streaming service Neon.
While Game of Thrones has traditionally been broadcast in the spring, the team behind the show decided that moving it to later in the year would make sense this time round, allowing for more winter-time filming.
