If the project comes to fruition, it would join several other Thrones-related offshoots in various stages of development. A prequel titled House of the Dragon was ordered to series at HBO in late 2019 and will follow Daenerys’ (and Jon’s) ancestors in House Targaryen as the storied family begins its legendary fall. The series was co-created by Thrones author George R.R. Martin and Ryan J. Condal (Colony), and it stars Matt Smith (Doctor Who), Paddy Considine (The Outsider) and Olivia Cooke (Bates Motel). Thrones director Miguel Sapochnik and Condal will serve as co-showrunners.
