George R.R. Martin may be responsible for birthing the franchise, but even he doesn't know how HBO's Game of Thrones is going to end. The author wrote the A Song of Ice and Fire novel series that the hit TV show is based on. However, the show eventually surpassed Martin's writings in the fifth season and, as such, they're treading on new ground. And Martin has opted not to know in advance where the show's creators David Benioff and D.B. Weiss are taking things.

During a recent interview, George R.R. Martin revealed that not only has he not read the scripts for Game of Thrones season 8, but that he hasn't even had time to visit the set. This is because the 70-year-old author has been plugging away at The Winds of Winter, what will ultimately be the sixth book in his series that fans have been feverishly, and impatiently, waiting for nearly eight years. Here's what Martin had to say about it.

"I haven't read the [final-season] scripts and haven't been able to visit the set because I've been working on Winds. I know some of the things. But there's a lot of minor-character [arcs] they'll be coming up with on their own. And, of course, they passed me several years ago. There may be important discrepancies... It's the end for a lot of people. It's not the end for me. I'm still deeply in it. I better live a long time because I have a lot of work left to do."

The Jon Snow cliffhanger at the end of Game of Thrones season 5 is where the books and the show parted ways. While George R.R. Martin did show Benioff and Weiss his rough outline, they have had to take creative license in order to finish out the show. Martin, for his part, also expressed regret for not finishing the books before the show wrapped up, given the current situation he finds himself in.

"It's been an incredible ride. And almost all of it has been great. Obviously, I wished I finished these books sooner so the show hadn't gotten ahead of me. I never anticipated that."

Ultimately, it just means that fans of the world of Westeros will have more to look forward to. And it means they will probably have two very different stories to enjoy when it's all over. Game of Thrones season 8 will be just six episodes long, but each of those episodes will feel like its own movie, as promised by HBO. That, coupled with the release of the recent trailer, ensures fans are in for an epic conclusion, no matter how different it ends up being from the books. Game of Thrones returns for its final season starting April 14. This news was first reported by Entertainment Weekly.
