Ramin Djawadi, whose award-winning score for “Game of Thrones” inspired a world tour, is returning to compose music for the prequel series.
While there are other Westeros-related series in development, “House of the Dragon” is the only confirmed “Game of Thrones” spinoff show — so far. Martin, who signed a five-year development deal with HBO, is overseeing development on various ideas, including “Tales of Dunk and Egg,” “10,000 Ships,” “9 Voyages” and “Flea Bottom.”
