Deadline is reporting that HBO has found a writer for their next Game of Thrones spinoff 10,000 Ships, enlisting the services of screenwriter Amanda Segel to pen the pilot episode.
The potential series would follow the adventures of warrior queen Princess Nymeria and the surviving members of the Rhoynars, who traveled from Essos to Dorne following their defeat by the Valyrian Freehold in the Second Spice War. This migration took place around 1,000 years before the events depicted in the flagship series.
In the acclaimed fantasy drama, Arya Stark (Maisie Williams) named her direwolf after Nymeria, and the character was also presumably the namesake of Nymeria Sand (Jessica Henwick).
Segel's past writing credits include Marvel's Helstrom, Shooter, The Mist, The Player, Person of Interest, Nikita, Past Life, The Good Wife, and Without a Trace.
This is one of the three Game of Thrones spinoffs currently in development, along with 9 Voyages (Sea Snake), which has Bruno Heller (Gotham; The Mentalist) attached, and Flea Bottom, which is still searching for a writer. An adaptation of George R.R. Martin's Tales of Dunk & Egg is also said to be in consideration.
No word on which project could follow House of the Dragon, but regardless, it seems as though HBO is understandably more interested in exploring the past of this vast world than the possibility of developing a Game of Thrones sequel series.
