Although work has already begun on 'The House of the Dragon', the Targaryen-centric spinoff set hundreds of years before the events of 'Game of Thrones', there's now going to be more spinoffs on the way.
Previously, HBO had said that there was to be a bake-off situation where writers would come together and pitch stories and concepts, with those having the most potential winning out. The end result of this process was, well, 'The House of the Dragon' winning out and the Naomi Watts-led series being cancelled before it began.
Deadline, however, is now reporting that HBO has three additional 'Game of Thrones' prequels in the works, with one of the three already having a concept formed and a showrunner attached in Bruno Heller. Best known for his work on HBO's 'Rome' (which was cancelled to make way for 'Game of Thrones', by the way), that series is understood to be called '9 Voyages', and follows a character known as the Sea Snake, who travelled across all of Westeros as a plunderer and explorer.
The second spinoff is about Flea Bottom, the maze-like slums of King's Landing where Ser Davos Seaworth, Gendry The Bastard, and plenty of other characters hail from. Last but not least, the third spinoff is called '10,000 Ships' and follows Princess Nymeria, who fled with the last of the Rhoynars and settled in Dorne. You might also remember that Arya named her direwolf after that character.
The likelihood of all three of these spinoffs making it to screens is, admittedly, less than good. HBO has been pretty brutal about shows in the past and if it's not working, it's getting the chop. While these three ideas may be in the early stages and have established showrunners onboard, that's still a long way to go before it's on TV and there's no guarantees they'll even get that far.
Still, of the three, any one of them has the potential to be turned into an interesting series. Flea Bottom, from the parts revealed in 'Game of Thrones', has plenty of stories to tell. The idea of a seafaring adventure set in the world of Westeros could be exciting - make it like 'Master and Commander' but as a TV series, and you've got us roped in. As for the Dorne / Princess Nymeria one, sure, it sounds quite similar to 'Game of Thrones' in the idea of a powerful woman forming a nation of her own, but yeah, why not?
Either way, we'll be keeping an eye on this whole story as it develops.
