Die-hard fans of the global ‘Game of Thrones’ series have just received exciting update. HBO has officially announced a new spinoff series, ‘A Knight of the Seven Kingdoms.’ Here’s the complete breakdown:

Prequel of Game of Thrones

In case you are wondering, ‘A Knight of the Seven Kingdoms’ will be a prequel to the famous ‘Game of Thrones’. This story is once again created by George R.R. Martin along with Ira Parker. The casting process was held in 2021, and production took place in June 2024.

The prequel will capture the adventures of Ser Duncan the Tall and Aegon V Targaryen from the Tales of Dunk and Egg novellas by George R. R. Martin. This new tale will be set 90 years before ‘A Song of Ice and Fire’ series. So, it’s obvious that the characters are quite different from what we have seen in ‘Game of Thrones’.

”Still, we can see some familiar sights like Westeros, Targaryen dynasty, and the magnificent Iron Throne.”

‘A Knight of the Seven Kingdoms’ airing date

The series will be available to watch on January 18, 2026 on HBO Max. HBO revealed it in a trailer published on various social media platforms, including Instagram and YouTube. The trailer itself is 2 minutes and 33 seconds long and was released on October 10, 2025.

In the trailer, we get to see the main character Duncan the Tall, played by Peter Claffey. We also could see other important characters like Prince Aerion Targaryen, Tanselle, and Prince Aegon Targaryen aka ‘Egg’. Make sure you ready to witness another masterpiece from George R.R. Martin in early next year.

”Because this is a tall tale that became legend.”
