HBO is developing three more Game of Thrones prequel projects. They include 9 Voyages aka Sea Snake, Flea Bottom, and 10,000 Ships.

According to The Hollywood Reporter, the network has a trio of additional ideas in the works based on author George R.R. Martin’s fantasy world.

One of the projects, working title 9 Voyages, is from Rome creator Bruno Heller and follows Lord Corlys Velaryon, a.k.a. The Sea Snake, the Lord of the Tides and head of House Velaryon.

The character also appears in the upcoming greenlit GoT prequel House of the Dragon, where he’s played by actor Steve Toussaint. So this effort represents a potential spinoff of a character from a series that hasn’t yet been shot.

A second project, working title 10,000 Ships, revolves around the warrior queen Princess Nymeria, a revered ancestor of House Martell who founded the kingdom of Dorne (she became so legendary in the realm that two characters bore her name in the original series – Sand Snake Nymeria Sand and Arya’s dire wolf).

Her story is set roughly 1,000 years before the events in Game of Thrones, making it much older on the Westeros timeline than any of the other previously announced projects in the works.

The third project is set in the notorious King’s Landing slum of Flea Bottom, the maze of tight streets in the capitol city where characters like Davos Seaworth and Gendry Baratheon were born.

According to Deadline, word of the new projects emerges after HBO and HBO Max Chief Content Officer Casey Bloys said last month that they’ve been talking about various areas to develop:

We are talking about other areas that make sense as well. George R.R. Martin’s world is so big and what’s interesting about it, not only is it big but he’s got a lot of road maps in terms of history. So, one of the great things about House of the Dragon is that’s an established history that leads you to Game of Thrones the show, and there is a lot of little branches. There is a lot of opportunities and stories to tell.

The projects are in addition to the upcoming greenlit series House of the Dragon, which begins filming in the UK in April and stars Olivia Cooke, Emma D’Arcy, Paddy Considine, and Matt Smith.
