DUBAI: At a time when the sprawling saga of “Game of Thrones” and its prequel “House of the Dragon” have come to define modern fantasy television, “A Knight of the Seven Kingdoms” emerges as an unexpected offering.

Based on George R.R. Martin’s “Tales of Dunk and Egg” novellas, the six-episode HBO series — created and spearheaded by showrunner Ira Parker alongside Martin — gives viewers a story that is not about dragons or imperial politics, but about two unlikely companions navigating a treacherous and unforgiving world from its humbler margins.

From the opening moments of the premiere, where the familiar “Game of Thrones” theme music is undercut in a moment of shocking levity, the show makes clear that we are far away from the grand halls of Casterly Rock, the Red Keep or even Winterfell. Grounded and whimsical, this is Westeros viewed from muddy inns, dusty roads and makeshift jousting camps.

Peter Claffey as Ser Duncan “Dunk” the Tall is the beating heart of the series. Claffey imbues Dunk with an endearing earnestness — a towering, awkward figure, constantly walking into doors, whose moral compass is as unwavering as his endless appetite.

His chemistry with Dexter Sol Ansell’s young squire, Egg, who has deep secrets of his own, is warm and organic, creating a duo that is as compelling as any knight and squire of fantasy lore. Their dynamic gives the story a cozy, almost heartfelt buddy-adventure quality.

What makes “A Knight of the Seven Kingdoms” so captivating isn’t its lack of spectacle. It has plenty of Westerosi trappings and there’s a sizeable helping of Targaryens and Baratheons and who have you. But its choice to focus on everyday courage, loyalty and the messy, funny, sometimes mundane reality of being a hedge knight truly makes this a worthy addition to the “Game of Thrones” screen universe. We hope there’s more where that came from.
