Aegon's Conquest writer hints at work on another Game of Thrones prequel

Game of Thrones ended back in 2019, but the Game of Thrones universe may only be beginning. The hit prequel show House of the Dragon returns for a second season in June, and just recently we learned casting information about another prequel series, A Knight of the Seven Kingdoms: The Hedge Knight, most likely to premiere in 2025.

Those are the two TV shows that we know HBO is officially making, but they've been quietly developing several others in the background, including a Jon Snow sequel series about a show about Aegon the Conqueror, the first Targaryen king of Westeros. Back in February, HBO was "actively heating up" development on the Aegon show, hiring writer Mattson Tomlin — who worked on The Batman with Robert Pattinson and wrote the upcoming sequel — to dig into the idea. Now, Tomlin has posted a picture of a laptop, a notebook, and a copy of Fire & Blood, the George R.R. Martin book that would form the basis for his show, implying that work is ongoing. "I've got a pretty sick job," he wrote.

Agreed!

HBO is developing a show about Aegon the Conqueror, but they haven't given the go-ahead

Note that none of this means that HBO is actually moving forward with a show about Aegon the Conqueror, who conquered the Seven Kingdoms with his sister-wives Rhaenys and Visenya some 300 years before the events of Game of Thrones. They've developed many Game of Thrones spinoff shows over the years, a couple of which have gone forward — House of the Dragon and A Knight of the Seven Kingdoms — and most of which never made it to TV. It's too early to tell what will become of the Aegon show.

Personally, I hope HBO takes its time with this kind of thing and doesn't greenlight too many Game of Thrones spinoff shows just because. With House of the Dragon, HBO has successfully continued the legacy of the original show without giving people too much of a good thing. A Knight of the Seven Kingdoms is a very different sort of Game of Thrones show, and new seasons probably won't air in years when we get new seasons of House of the Dragon. I'm hoping that will work, too.

But I don't want to have multiple Game of Thrones shows on the air at the same time to the point where we get sick of these stories. I think an Aegon show might be a good pick for after House of the Dragon is over, but we'll see how HBO and parent company Warner Bros. Discovery play it. For now, the second season of House of the Dragon premieres on HBO and Max on June 16.
