HBO's Game of Thrones may currently be on an extended winter break, but with filming already underway on season 8, the latest set leaks tease a huge battle at King's Landing.

With the frosty fantasy winding down, and only six episodes left ever, the action-packed final season is sure to be filled with bloodshed and battles. As Queen Cersei Lannister sits uncomfortably on the Iron Throne, it is fully expected that her various enemies will make moves on the capital at some point in season 8.

First spotted by Watchers on the Wall, the Thrones fansite noted that production in Northern Island is building a supersized set.

Constructed in Belfast's Titanic Quarter, the mysterious set looks to be the biggest to grace the show since it started back in 2010. However, with episodes in season 8 expected to cost upwards of $15 million each, showrunners David Benioff and D.B. Weiss look set to make good on their promise of an epic swansong.

While it still isn't clear what the latest addition is, the site guesses that it is probably part of King's Landing due to the sheer size and possibility of a large gate. Also, with a separate tower featured alongside, the magnitude of such a build implies that it will be a major part of the season. Elsewhere, the revamped Winterfell set at Moneyball has become a hive of activity, and could be preparing for the rambling approach of some zombified White Walkers.

Watchers on the Wall also teased that Winterfell is laying tarps for a blanket of fake snow, while the rumors intensify for a showdown between Daenerys Targaryen's Unsullied and the Night King's army of the undead. Unsullied extras have been filming in recent weeks at Toome, Northern Ireland, and with that being just a stone's throw from Moneyball, it seems everyone is converging on the Stark homestead. Even more exciting, the Unsullied extras have apparently all been supplied with dragonglass spears - clearly tooling up to take on some frozen foes.

Cersei may have blown half her kingdom up, but could Thrones be building toward some colossal King's Landing drama? With the cast having gathered for table reads, and a slow leak of set spoilers, the long winter between now and season 8's 2019 release date will soon fly by. Whatever the future holds for the Iron Throne, fans are wondering whether season 8 will fulfill Dany's vision of a snow-covered throne room. Well, as they say, winter is coming.
