The Game of Thrones universe is expanding with A Knight of the Seven Kingdoms, a new adaptation from George R.R. Martin’s canon. The HBO series is another prequel set in the fictional Westeros, based on Martin’s novella series Tales of Dunk and Egg that follow Ser Duncan “Dunk” the Tall (Peter Claffey), future Lord Commander of the Kingsguard, and his squire “Egg” (Dexter Sol Ansell), who would later become King Aegon V Targaryen.
Egg’s explosive brother, Prince Aerion Targaryen, aptly nicknamed Aerion the Monstrous and played by Finn Bennett, becomes an obstacle in Dunk’s path as the two duke it out as the embodiments of good and evil. But despite stepping into the franchise as this show’s villain, Bennett didn’t watch the original series until the pandemic. “Lockdown was obviously really miserable, but at least I had Game of Thrones,” he told The Hollywood Reporter in 2025. “One of the great things about the show—and where a lot of fantasy shows faltered—is that it’s so political in looking at a kind of War of the Roses setup between these great and noble houses.”
