The first season of A Knight of the Seven Kingdoms will follow the exploits of the knight Ser Duncan the Tall (Peter Claffey) and his young squire, Egg (Dexter Sol Ansell), roughly 100 years before the events of Game of Thrones and 100 years after the events of House of the Dragon.

Their journey will take them to a competition in which they encounter several members of the Targaryen dynasty — including Prince Aerion Targaryen (Bennett), Prince Baelor Targaryen (Carvel) and Prince Maekar Targaryen (Spruell) — along with another knight known as the Laughing Storm, Ser Lyonel Baratheon (Ings), and a puppeteer named Tanselle (Crawford).

The series is written and executive produced by George R.R. Martin and Ira Parker, and executive produced by Ryan Condal, Vince Gerardis, Owen Harris, and Sarah Bradshaw.
