Hbo’s president of programming Casey bloys says the series likely wo n’t air until’sometime in 2022,’ via deadline.

Hbo had several other game of Thrones successors in the works, but all focus right now is on house of the dragon.’there are no other blinking green lights or anything like that,’ bloys said.

House of the dragon is based on George R.R. Martin’s 2019 book fire and blood. The book is set 300 years before the events of game of Thrones.

The book explores the politics, civil wars, and intrigue throughout history. Martin has just published the first of two planned fire and blood books. A song of ice and fire starts is planned for the future.

House of the dragon will be broadcast on HBO next week. It’s possible the show will focus on just one part of house Targaryen’s history, like AEGON’s conquest or the dance of the dragons.

Hbo passed on another in-development game of Thrones prequel that had been set 8,000 years before the events of the original show.

bloys says she set hers 8,000 years before the (mothership) show, so it required a lot more.’that is a big swing,’ says bloys.

George R.R. Martin revealed that house of the dragon had a key advantage. The lack of which ultimately had a huge impact on game of Thrones.
