We already knew season 8 would not be the last time we step foot in Westeros. The series creator George R.R. Martin has previously confirmed that various prequels are in the works (in both book and film versions) and today the writer announced a fifth HBO prequel to the cult series is in the early stages of development.

Writing to his LiveJournal, R.R. Martin confirmed: "Truth be told, we've had five scripts in various stages of development for months. Which I believe I mentioned... But now at last all the deals are signed, and it can be told. BRYAN COGMAN has come on board to pen the fifth of the successor shows."

The fifth spinoff is in good hands; Cogman has been a part of the show since before the first season. He was hired as an assistant to the show's writers/producers David Benioff and D.B Weiss before the pilot had even been filmed. He has written more episodes for Game of Thrones than anyone, bar Benioff and Weiss. "If D&D [Benioff and Weiss] have been the kings of Westeros for these past seven seasons, Bryan Cogman has surely been the Prince of Dragonstone," R.R. Martin penned in his blogpost.

"I can say that, like the other pilots, it will be a prequel rather than sequel, a successor rather than a spinoff. Bryan's series will be an adaptation, and one that will thrill most fans of the books, I think, set during a very exciting period of Westerosi history," R.R. Martin wrote.

But don't expect to see all five shows make it to air, and don't expect to see them anytime soon. R.R. Martin predicts that we could possibly see two or three of the prequels make it to the pilot stage, but this may not be until 2019 or 2020.

At any rate, with five prequels in the works, the origins of Westeros could look to overtake the traditional Game of Thrones series in length. What is dead may never die. 

It looks like we will be seeing A LOT more Game of Thrones spinoffs
