HBO has announced Confederate, the next project from David Benioff and D.B. Weiss, the creators, writers, producers, and showrunners behind their mega-hit series Game of Thrones.

The series is set in an alternate historical timeline, in which the southern states successfully seceded from the United States and events are leading toward a third American Civil War.

Some type of spinoff to HBO’s Game of Thrones has been expected since we the fans, and especially HBO, realized how big of a hit it was. The world that the “Song of Ice and Fire” series is set in runs so very deep with history, it can be overwhelming to try to take it all in. It would be crazy not to bring some of those other stories to life. There’s a wealth of great tales to be told—especially ones that happened before the events of the show—such as Robert’s Rebellion, the Children of the Forest (seen above), the fall of the city of Valyria, and so many more. That’s why it was no great shock to find out that, after the main series wraps up, a prequel was more likely than a spinoff.

Now comes news even more exciting than just a potential prequel. It’s being reported that not one, but FOUR different potential Game of Thrones spinoffs are now being developed, and four writers have signed on to work on them along with George R.R. Martin.

At the Game of Thrones panel at this year’s SXSW, showrunners D.B. Weiss and David Benioff said they’d love to do an episode of Adult Swim’s Rick and Morty once the HBO series concludes.

The response came from a question about what the pair’s plans are beyond the show. As a bit of a surprise, neither hesitated to respond in agreement about collaborating on the sleeper hit cartoon series co-created by Justin Roiland and Dan Harmon. There was, however, one big catch…

Die hard Game of Thrones fans will know that there have been several instances throughout the run where well-known musicians made subtle appearances. And at SXSW 2017 today, showrunners David Benioff and D.B. Weiss revealed that this season is no different.

While neither made mention of the exact episode or scene, it was confirmed on stage that musician and adult-Ron Weasley lookalike Ed Sheeran will be making his way to Essos.

We’re speeding toward the end of Game of Thrones (*sniffle*), and that’s something we just have to accept (knock it off, you promised yourself you wouldn’t cry). But while the end of the main series begins to come into view, anyone who has been paying attention knows that this is more than likely not the end of our time in Westeros and the surrounding areas.

For a while now we’ve been hearing about the potential for a spinoff series, which would focus on other stories set in other times. Those familiar with author George R.R. Martin‘s “A Song of Ice and Fire” world know there’s an incredible amount of history there, much of which would make for some great TV. HBO’s president of programming Casey Bloys talked about this recently, saying it would more likely be a prequel series than a spinoff. He also revealed that season eight of the current show, the final season, could end up being a little longer than previously believed.
