Snow is coming.

George R.R. Martin, author of the Game of Thrones saga, said the recently-announced sequel, centered around the character of Jon Snow, has a working title (Snow) and is the creation of Kit Harington, who played the hapless bastard on GOT.

Martin notes in a recent blog post that Harington came up with the concept for the spinoff, adding that “It was Kit Harington who brought the idea to us. I cannot tell you the names of the writers/showrunners, since that has not been cleared for release yet… but Kit brought them in too, his own team, and they are terrific.”

This spinoff is set to be a sequel, unlike the other Thrones prequel spinoffs currently in the works. (The first, House of the Dragon, debuts on HBO in August.) At the end of Thrones, Jon Snow was once again banished to the Night’s Watch after killing his aunt/lover Daenerys. Snow was last seen heading north of the Wall with his direwolf Ghost.

Martin, who is still at work on the sixth GOT book (The Winds of Winter, release pending since forever), will be involved in the show as well.

“I am involved, just as I am with [the Thrones prequels in the works] The Hedge Knight and The Sea Snake and Ten Thousand Ships, and all the animated shows,” he wrote. “Kit’s team have visited me here in Santa Fe and worked with me and my own team of brilliant, talented writer/ consultants to hammer out the show,” he blogged.

While Emilia Clarke, who played Daenerys, is not planning a return to the world of Thrones, one actor is ready to start singing A Song of Ice and Fire again.

“Brienne of Tarth is incredibly close to my heart, and I would relish any opportunity to revisit her. I believe she is enduring,” Gwendoline Christie told Newsweek. Christie joined the show as Brienne in the second season and the formidable warrior survived all the way to the end, which was something of a feat.

“I feel incredibly and genuinely honored and so fortunate to have had the opportunity to play that character that I have loved with all of my heart for all of that length of time, for that decade,” Christie said, adding that “maybe” she would be involved with Snow.
