Everything we know so far about the 'Game of Thrones' prequel
In just three days, Game of Thrones will come to an end and someone (or no one) will finally sit on the Iron Throne.
While this series has had its fair share of memorable moments, such as Arya's eleventh-hour slaying of the Night King and the long-awaited Cleganebowl, generally speaking, it's divided fans.
In fact, there's even a petition calling for it to be remade.
Relive the glorious moment Arya kills the Night King to save Bran:
This division grew in the wake of episode five, The Bells, which saw Daenerys, in a complete betrayal of everything her character stood for, needlessly kill countless innocents in King's Landing.
However, regardless of what happens at the end, even the most disappointed fans can take comfort in the knowledge that filming has begun on its prequel, Bloodmoon, in Belfast, where much of GoT was filmed.
This is everything we know about the prequel so far.
Firstly, it's set thousands of years before the current storyline (although the exact date is not known), which, when you think about it, could have been totally avoided if Rob Stark had listened to Catelyn's advice and simply not gone to King's Landing in the first place.
Bloodmoon will focus on the Children of the Forest, and, most interestingly, the origins of the white walkers and the Night King - chronicling "the world's descent from the Golden Age of Heroes into its darkest hour."
For anyone who isn't a Westeros encyclopedia, the Age of Heroes comes after peace was made between the Children of the Forest and the First Men.
During this period, many of Westeros enduring houses like House Stark were formed. But its synopsis from HBO has warned: "it's not the story we think we know."
The first cast member to be officially announced was, who will be playing a woman described as "a charismatic socialite hiding a dark secret."
A number of other cast members have also been announced including Jamie Campbell Bower (Harry Potter and the Deathly Hallows Part 1), Georgie Henley (The Chronicles of Narnia) and Miranda Richardson (Harry Potter and the Goblet of Fire).
In terms of a release date, Casey Bloys, HBO's head of programming, said that the prequel would not be hitting our screens until at least a year after GoT has drawn to a close, so it's earliest possible release date is 2020.
However, given that there was a two-year break between seasons seven and eight of GoT, it is likely to be longer.
This is the preview trailer for the last ever episode of Game of Thrones:
This prequel may not bethe only time we will return to Westeros, either, as George R. R. Martin previously spoke of a number of spinoffs.
"We have had five different Game of Thrones successor shows in development," he wrote in May, "and three of them are still moving forward nicely. The one I am not supposed to call The Long Night will be shooting later this year, and two other shows remain in the script stage, but we are edging closer.
"What are they about? I cannot say."
