The most powerful warriors of Westeros are finally coming together in the season finale of "Game of Thrones."

A promo for the last episode teases a meeting that's been a long time coming, as Cersei and Jamie Lannister receive Tyrion, Jon Snow, Gendry, Theon Greyjoy, Jorah Mormont, Davos Seaworth and Brienne of Tarth in the ruins of Dragonpit in King's Landing.

Mysteriously absent: Dany, who must have send Jon on her behalf.

"There's only one war that matters and it is here," Jon warns Cersei, relaying the threat of the Night King and his army of white walkers, which now includes an ice dragon.

While neither The Hound or The Mountain appear in the teaser, many fans are speculating the finale will result in the long-awaited Cleganebowl, a rumored duel between the two brothers.

Supporting this theory is a shot from the second trailer for Season 7, which shows who appears to be The Hound drawing his sword in the same Dragonpit seen above. See the evidence at the 1:20 mark below.

The season finale of "Game of Thrones" airs Sunday, August 27 on HBO.
