HBO is developing three more Game of Thrones prequel projects, including one title 9 Voyages from Rome’s Bruno Heller and another about the founder of Dorne, dubbed 10,000 Ships. The third is set in the King’s Landing slum of Flea Bottom.

They join House of the Dragon, which begins filming in the U.K. in April and stars Olivia Cooke, Emma D’Arcy, Paddy Considine and Matt Smith.
