The Game of Thrones extended universe is continuing to expand, as George R.R. Martin just gave a major update on the franchise’s newest show. As well as Season 3 of House of the Dragon and several other new spin-offs currently in development, HBO is also working on A Knight of the Seven Kingdoms, which adapts one of Martin’s smaller stories set in Westeros. Season 1 of the new series, which stars Peter Claffey as Ser Duncan the Tall, a.k.a. Dunk is set to premiere sometime this year. But, HBO apparently has a lot of confidence in the latest series having a long future.
