The new Game of Thrones prequel series is under development. The first one hails from “Rome” titled 9 Voyages or Sea Snake. On the other hand, Flea Bottom and 10,000 Ships do not have any writers on board yet. The first spin off 9 Voyages is confirmed to center on Sea Snake, Lord Corlys Velaryon – head of House Velaryon and a husband to Rhaenys Targaryen.
Flea Bottom is known to be placed in the poorest district of King’s Landing whereas 10,000 ships is likely to revolve around the life of Princess Nymeria who got married to Lord Mors Martell and further also journeyed with the Rhoynar to Dorne.
