HBO is not done with the Game of Thrones universe just yet. While the main series ended in 2019, there are several spin-offs and prequels in the works. One of the first spin-offs, House of the Dragon, premiered in 2022 and has already been renewed for a second season. The second season is currently in production in the UK, despite ongoing strikes in Hollywood. The show features new characters from George R.R. Martin's novel Fire & Blood, as well as returning stars from the first season. The departure of co-showrunner Miguel Sapochnik has resulted in Alan Taylor joining as an executive producer and director for the second season.
Another spin-off in development is The Sea Snake, which would focus on the character Corlys Velaryon. Although the actor who plays Corlys in House of the Dragon may not reprise his role, he has expressed interest in being involved in the new series. There is also a planned sequel series that would follow the character Jon Snow. Kit Harington is set to reprise his role, and the idea for the series was brought to HBO by Harington himself. The series would explore Jon's life after the events of Game of Thrones.
In addition to these spin-offs, there is a TV series in development based on Martin's novellas about two characters called Dunk and Egg.
Lastly, there are rumors of an animated Game of Thrones series in the works, with the working title The Golden Empire. The series is said to be set in Yi Ti and is being developed by a young writer. While details about this series are scarce, Martin has expressed excitement about the concept art and animation.
Overall, it seems that the Game of Thrones universe will continue to expand with these upcoming projects, providing fans with more stories from the world of Westeros. [300 words]
