Yesterday we reported the breaking news that Game of Thrones’ prequel starring Naomi Watts was canceled by HBO. Almost immediately after, HBO announced a whole different series was coming in its place.

House of the Dragon, which is based on Fire & Blood, the 2018 book written by Martin himself, is set to take place roughly three centuries prior to the events of Jon Snow and Tyrion Lannister walking Westeros. The book is mostly about the history of House Targaryen, outlining the rise and fall of the great house itself. Expect to see a lot of CGI dragons in this one.

No casting details have been announced, although it is safe to say we likely won’t be seeing many familiar actors from the mainstay series.

If you need a breakdown of the book to help you set your expectations of what the show will cover, you can head over to EW where they have broken it down in a simple manner to elaborate on the timelines in which this show takes place.

No additional details have been shared, although word is getting around that Martin himself is going to be heavily involved, likely due to the screw-ups of Benioff and Weiss of the main series.
