HBO’s A Knight of the Seven Kingdoms continues to expand its world, and the newest casting announcement suggests that the upcoming season will bring one of the most memorable characters from George R. R. Martin’s Dunk and Egg novellas to life.
Lucy Boynton has officially joined the cast of A Knight of the Seven Kingdoms season 2, where she will portray Lady Rohanne Webber, a character deeply connected to one of the most beloved stories in the Dunk and Egg saga. The announcement immediately sparked excitement among fans familiar with the source material, particularly the novella The Sworn Sword, which introduces Rohanne as a sharp, determined noblewoman who becomes entangled with Ser Duncan the Tall.
For viewers who have followed the first season of HBO’s Game of Thrones prequel, the addition of Rohanne signals a clear direction for the next chapter of Dunk and Egg’s journey.
Who Is Lady Rohanne Webber?

In George R. R. Martin’s stories, Lady Rohanne Webber is the young ruler of Coldmoat, a powerful noble house in the Reach. Despite her youth, Rohanne commands respect and authority over her lands, which are caught in a tense dispute with the neighboring House Osgrey.
When Ser Duncan the Tall and his squire Egg arrive in the region, they find themselves drawn into the conflict between these houses. What initially appears to be a simple political disagreement slowly reveals deeper themes about honor, survival, and the fading glory of once powerful families.
Lady Rohanne is central to that story. She is intelligent, pragmatic, and fully aware of the challenges of ruling in a brutal feudal world. Unlike many noble characters in Westeros who rely on lineage alone, Rohanne actively defends her lands and navigates the complicated politics surrounding her.
Casting Lucy Boynton as Lady Rohanne Webber suggests that HBO intends to faithfully adapt the events of The Sworn Sword, which many fans consider one of the strongest Dunk and Egg tales.
Why Lucy Boynton Is an Interesting Choice
Lucy Boynton is widely recognized for her roles in projects such as Bohemian Rhapsody and The Politician. She has developed a reputation for portraying characters with quiet intensity and emotional depth, traits that align well with Rohanne Webber’s personality.

Lady Rohanne is not a conventional fantasy heroine. She is strategic, proud, and often guarded, shaped by the political pressures of ruling her house at a young age. The character must balance authority with vulnerability, making the role particularly demanding for any actor.
Boynton’s casting suggests that the showrunners are looking for someone capable of bringing nuance to the role rather than simply presenting Rohanne as another noble figure in Westeros.
For a series that places character relationships at the center of its storytelling, this choice could significantly shape how the events of season 2 unfold.
What This Means for A Knight of the Seven Kingdoms Season 2
The presence of Lady Rohanne Webber strongly indicates that A Knight of the Seven Kingdoms season 2 will draw heavily from The Sworn Sword, the second novella in Martin’s Dunk and Egg collection.
If the show follows the structure of the books, the story will see Ser Duncan the Tall and Egg traveling through the Reach during a harsh drought. Their journey leads them to serve the aging Ser Eustace Osgrey, whose lands are in conflict with Rohanne Webber’s domain.
At the heart of the narrative lies a dispute over water rights that escalates into a conflict involving loyalty, honor, and survival. While the stakes may appear smaller compared to the epic wars of Game of Thrones, this story highlights the everyday struggles of Westeros’ lesser houses.
That grounded perspective is precisely what makes A Knight of the Seven Kingdoms unique among HBO’s fantasy series.
Instead of focusing on dragons, massive armies, or throne politics, the show explores the lives of wandering knights and small lords trying to navigate a fragile peace following the Targaryen civil war.
A Character with Future Westerosi Legacy
Fans of the books also know that Lady Rohanne Webber’s importance extends beyond her role in The Sworn Sword.
Rohanne’s story eventually connects to one of the most prominent houses in Westeros history. According to George R. R. Martin’s extended lore, she later becomes linked to House Lannister, creating a fascinating bridge between the era of Dunk and Egg and the timeline of Game of Thrones.
While it remains unclear whether the HBO series will explore this aspect of her life, the possibility adds additional intrigue to the character’s introduction.
Even if the show focuses primarily on the events of the Dunk and Egg novellas, Rohanne’s presence helps reinforce how interconnected Westeros’ history truly is.
The Growing Anticipation for Season 2
Although A Knight of the Seven Kingdoms season 1 has only recently introduced audiences to Dunk and Egg’s journey, anticipation for season 2 is already building. Casting announcements like Lucy Boynton’s continue to signal that HBO is confident in the long term future of the series.
And if Lucy Boynton’s casting is any indication, A Knight of the Seven Kingdoms is continuing to assemble a cast capable of bringing Martin’s richly layered characters to life.
