Game of Thrones as we know it is coming to an end at HBO.

But the premium cable network is not ready to say goodbye to one of the most popular shows on all of TV and is looking to extend the franchise with new series set in the same universe.

With the news that HBO has handed out a pilot order to one of the four spinoffs in the works, it has now been revealed that the pilot will film in the same place many of Game of Thrones' biggest scenes have been filmed.

According to the Belfast Telegraph, that location is The Paint Hall in Belfast’s Titanic Quarters. What's more, the filming start date is sooner than you may think.

It will start filming in October. It's very soon and means that the casting process must be well underway by now. Little is known about the series which has been created by Jane Goldman.

Per the official logline, “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.”

Back in June, George R.R. Martin added in a blog post, “None of the characters or actors from Game of Thrones will appear in the new show."

"All of the successor shows we’ve been developing have been prequels, as I have mentioned before."

"This one really puts the pre in prequel, since it is set not ninety years before Game of Thrones (like Dunk & Egg), or a few hundred years, but rather ten thousand years (well, assuming the oral histories of the First Men are accurate, but there are maesters at the Citadel who insist it has only been half that long). We’re very early in the process, of course, with the pilot order just in.”

It makes sense that the new offshoot would want to veer away from the parent series. A lot of fans like a series to have a finite conclusion, and that means not having characters appear in other shows.

Furthermore, the actors and creative forces behind the show have been adamant that the story for all of the characters will end after the final six episodes.

It would be a bit much to promote it as the end and then continue plots in another show.

Then again, it's becoming increasingly worrying to think about how the show is going to service all of the characters with just six episodes remaining.
