Sure, everyone is whining about Dany’s digitally edited coffee cup and leaked images of Jaime’s phantom hand right now — but something tells us when the time comes, diehard GoT fans will show up for the first of four spin-offs HBO currently has in the works.

Here’s what we know about the much-anticipated Bloodmoon series right now:

The title: George R.R. Martin previously announced that he thought the prequel should be titled The Long Night, but what does he know? He only authored the A Song of Fire and Ice book series the show is based upon.

The plot: Set more than 5000 years before the events of the current series, the new series will follow the story of the Children Of The Forest.

On his blog, Martin teased that the action might be based on the Fire and Ice companion book Fire & Blood, featuring dragons and “all the Targaryen kings from Aegon I (the Conqueror) to the regency of Aegon III (the Dragonbane), along with their wives, wars, siblings, children, friends, rivals, laws, travels, and sundry other matters.”

The air date could be sometime this year, according to some reports.

HBO still hasn’t announced an official air date for the premiere episode, which is directed S.J. Clarkson (The Defenders and next Star Trek film) from a script by Martin and Jane Goldman, the scribe behind “The Kingsman” series and two X-Men entries.

The cast is packed with acclaimed international actors, including two-time Oscar nominee Naomi Watts who is set to headline as “a charismatic socialite hiding a dark secret”.

Fan theorists are speculating online that she will play Nissa, wife of Azor “Lord of Light” Ahai, a leading figure of the faith of R’hllor.

Watts will be joined by fellow double-Oscar nominee Miranda Richardson — AKA Rita Skeeter in the Harry Potter films. Marques Rodriguez, soon to be seen in Ava DurVernay’s Central Park Five limited series, When They See Us, on Netflix is also a series regular.

Brit thespians John Simm (Doctor Who), Richard McCabe (Collateral), John Heffernan (The Crown), Jamie Campbell Bower (The Crimes of Grindelwald), and Dixie Egerickx (Patrick Melrose) round out the primary cast.

Beyond that, a batch of relative unknowns fills the call sheet: Naomi Ackie (Star Wars: Episode IX), Denise Gough (Guerrilla), Alex Sharp (To the Bone), Toby Regbo (Reign), Georgie Henley (The Chronicles of Narnia), Ivanno Jeremiah (Humans) and Sheila Atim (Harlots).

Three more Game of Thrones prequels are also planned, with the original series due to end on Monday.

The sixth and final episode of Game of Thrones will air next Monday on Foxtel at 11am and 8.30pm. Keep an eye out for news.com.au’s recap and podcast analysing the episode.
