House of the Dragon, a Game of Thrones prequel series, will begin filming next month, and an animated spin-off is in the works, as well as a show based on George RR Martin's Tales of Dunk and Egg novellas.
However, it appears that even more Westeros is on the way.
HBO appears to be creating three new prequel concepts: 9 Voyages, also known as Sea Snake, Flea Bottom, and 10,000 Ships.
According to Deadline, 9 Voyages is the only one with a creative team working on it right now. Martin is collaborating on the project with Bruno Heller, the maker of The Mentalist, Rome, and Gotham.
The title refers to Lord Corlys Velaryon's and later his grandson, Lord Alyn Velaryon's long sea voyages aboard the Sea Snake ship. Many Westeros ships had sailed as far as Qarth in search of spices and silk, but Corlys dared to go much farther, reaching the fabled lands of Yi Ti and Leng, whose riches doubled that of House Velaryon in a single voyage.
The most destitute part of King's Landing, the capital of the Seven Kingdoms of Westeros, is Flea Bottom, which is featured in the first four seasons of Game of Thrones.
Many prostitutes and criminals live here, as do the needy and unwanted. Ser Duncan the Tall, a future Lord Commander of the Kingsguard, and Lord Davos Seaworth, a future Hand of King Stannis Baratheon, are two notable Flea Bottom natives.
Finally, 10,000 Ships alludes to Princess Nymeria's and the remaining Rhoynar's journey after their defeat by the Valyrian Freehold in the Second Spice War. A thousand years before the events of A Song of Ice and Fire, a Rhoynish migration took place.
While it's unlikely that all three of these concepts will materialize, HBO president Casey Bloys revealed his vision for the network's post-Thrones future last month – and it appears that there isn't a specific number of prequels in mind.
"I'd rather not come up with some arbitrary number – I want three shows, five shows, ten shows, whatever," he explained. "I make an effort to speak with the team about the stories we're telling and the characters worth highlighting."
"The number of shows I like is equal to the number of good shows. As a result, rather than picking a number and working backward, I try to let that be our guide. That's what we'll do if the show is successful."
