Game Of Thrones Spin-Off Green-Lit By HBO

A new series is coming.

What you need to know
  • HBO greenlit pilot for Game of Thrones prequel
  • It will be set thousands of years prior to the events of the series
  • It's set to air in 2020 after the existing series concludes next year

Rug up everyone, because more winter is coming.

OFriday June 8 -- a very good day -- HBO announced that it's given the go-ahead to a Game of Thrones prequel pilot. It will be penned by series author George R.R. Martin and Jane Goldman, who wrote Kick-Ass and Kingsman: The Secret Service.

We are very excited.

The as-yet-untitled pilot -- which was one of five spin off options HBO had on the boil -- will reportedly be set thousands of years before the current series. Well, more specifically, 10,000 years earlier, according to Martin's books.

And the official HBO logline for the spin off is giving us CHILLS.

It states: "The series chronicles the world’s descent from the golden Age of Heroes into its darkest hour."

And only one thing is for sure: From the horrifying secrets of Westeros’ history to the true origin of the white walkers, the mysteries of the East, to the Starks of legend … it’s not the story we think we know.

'Not the story we think we know" ... that sounds familiar.

Storylines are expected to cover major events like the construction of the Wall and the ancestral home of House Stark, Winterfell. We may find out more about the generation-long winter known as the Long Night, and the events that led to a war against the White Walkers.

But don't hang out to see fan faves Jon, Tyrion or Dany pop up, although the dastardly Night King might make an appearance. Considering the huge time gap between the prequel and the original series we can expect to meet an entirely new set of characters.

Key players in the Age of Heroes -- again according to Martin's novels -- include Bran the Builder, Lann the Clever, the Grey King and the original Azor Ahai. You'll be excused if these names don't ring a bell.

Here's what we know/had to consult the books to find out. Not to be confused with his distant relative Brandon Stark, Bran the Builder constructed the Wall and Winterfell and founded House Stark.

Lann the Clever somehow stole Casterly Rock from the Casterlys and founded House Lannister, while the Grey King supposedly wed a mermaid and founded the Iron Islands. Warrior Azor Ahai led the fight against the terrifying White Walkers.

While casting announcements are still a way off, we're having fun creating our dream ensemble of actors in our heads. Whoever Goldman and Martin choose to star in the new series they'll have huge boots to fill and millions of hardcore fans to impress. No biggie.

Social media is bubbling with fan reactions ranging from the witty to excited and just plain unimpressed.

GoT returns for its six-episode, eighth -- and final season -- in 2019. But now we have something to look forward to after waving goodbye to Westeros as we know it. By our calculations, the prequel could hit screens within a year after the original series wraps.

That's if HBO gives the pilot the green light to be made into a full series. Better start sending prayers to the old gods -- and the new.
