HBO’s next Game of Thrones spinoff premieres in January

Today at this year’s New York Comic-Con, HBO announced that A Knight of Seven Kingdoms’ six-episode-long first season will begin airing on January 18th, 2026. Based on Martin’s Tales of Dunk and Egg novellas set decades before the events of A Song of Ice and Fire, A Knight of Seven Kingdoms chronicles the adventures of Ser Duncan the Tall (Peter Claffey) and prince Aegon Targaryen (Dexter Sol Ansell).

In the newly released trailer, no one really respects Ser Duncan — a lowly hedge knight who is eager to prove his worth and become a well-known figure across the kingdoms. But Aegon sees the large man as a potential ally who could help him travel to Ashford in the distant Reach. The two make an unusual pair in a land filled with far more formidable-seeming knight / squire duos. But the trailer teases some of how Dunk and Egg are destined to become players in some of the most important events in Westeros’ history.

The trailer makes A Knight of Seven Kingdoms seem a bit more lighthearted than HBO’s last Game of Thrones spin-off. But like House of the Dragon, the new show looks like it will have no shortage of battles and fire-breathing monsters, which will hopefully make it an exciting watch when the show debuts next year.
