House of the Dragon Season 3 Adds Three New Knights

House of the Dragon Season 3 has announced the addition of three new knights to its cast: Tom Cullen as Ser Luthor Largent, Joplin Sibtain as Ser 'Bold' Jon Roxton, and Barry Sloane as Ser Adrian Redfort. Largent, a lowborn knight known for his immense strength, becomes a pivotal figure as Commander of the City Watch and has shifting loyalties between the rival Targaryen factions. Roxton, head of House Roxton and wielder of the Valyrian steel sword Orphan-maker, is a fierce supporter of King Aegon II and the Greens. Redfort, hailing from the Vale, is loyal to Queen Rhaenyra and is set to play a key role as part of her Queensguard. These new characters join a returning ensemble cast led by Emma D’Arcy, Matt Smith, and Olivia Cooke, with the season currently in production and expected to premiere in 2026. Showrunner Ryan Condal has teased that four major events from George R. R. Martin's 'Fire & Blood' will be depicted in the upcoming episodes.
