HBO has made its first major casting move for A Knight of the Seven Kingdoms Season 2, adding Lucy Boynton as Lady Rohanne of Coldmoat, Babou Ceesay as Ser Bennis of the Brown Shield, and Peter Mullan as Ser Eustace Osgrey of Standfast. It is the first clear sign of how the series is building out its next chapter after Season 1 introduced viewers to Dunk and Egg and set the tone for a smaller, more grounded kind of Westeros story.
These three roles matter because Season 2 is expected to adapt The Sworn Sword, the second Dunk and Egg novella by George R. R. Martin. In that story, Ser Duncan the Tall and Egg become tied to a tense local conflict in the Reach, with Rohanne and Eustace at the center of the dispute and Bennis adding even more instability to the situation. For fans of the books, this is one of the more intimate and character-driven stories in Martin’s world, with less emphasis on giant battles and more focus on loyalty, pride, class tension, and the messy reality behind knighthood.
Boynton feels like an especially interesting choice for Lady Rohanne, a character readers know as sharp, formidable, and impossible to ignore. Ceesay as Bennis suggests the show wants a performer who can bring real edge to one of the story’s more volatile figures, while Mullan seems like a natural fit for Eustace Osgrey, whose personal history and stubborn pride give the story much of its emotional weight. On paper, this trio gives Season 2 a strong dramatic spine before HBO has even revealed much else.
The timing also tells fans that HBO is moving forward with confidence. Recent trade reports say Season 2 has already been filming in Belfast, with 2027 currently eyed as the target for its return. That means the show is wasting little time following up on a first season that helped separate A Knight of the Seven Kingdoms from the larger, more spectacle-driven corners of the franchise. Instead of trying to outscale Game of Thrones or House of the Dragon, this series continues to lean into something more personal, and these first castings suggest that approach is not changing anytime soon.
For longtime readers, this is the kind of update that makes Season 2 feel real. For casual viewers, it is a reminder that this series is carving out its own identity inside Westeros, one built less on dragons and palace warfare and more on the people caught in the cracks of a fading kingdom. And if HBO gets these characters right, The Sworn Sword could end up being exactly the kind of follow-up that turns Dunk and Egg from a promising spinoff into one of the franchise’s strongest stories.
