Duncan remembers his mentor, Ser Arlan of Pennytree, charging him with the duties of a good knight: protecting the helpless. Now a knight himself, Duncan reluctantly agrees to take on a young squire named Egg (Dexter Sol Ansell). The story takes place well after the events of *House of the Dragon*, but the Targaryen family still rules, and they’re just as troublesome as ever. Finn Bennett, known from *True Detective: Night Country*, plays Aerion Targaryen, sporting a strikingly similar bleached-blond hairstyle to Timothy Olyphant’s character in *Alien: Earth*, and isn’t shy about insulting Duncan. Bertie Carvel, Sam Spruell, Tanzyn Crawford, and Daniel Ings also star as Baelor Targaryen, Maekar Targaryen, Tanselle, and Ser Lyonel Baratheon, respectively. *A Knight of the Seven Kingdoms* will debut on January 18, 2026, and the show promises an enjoyable viewing experience – especially with a friend.
