There's something different with HBO's A Knight of the Seven Kingdoms. An adaptation of a series of novellas by author George R. R. Martin, this third live-action installment in the Game of Thrones Universe should be a realistic representation of the minutiae of life in Westeros. Two characters, namely, Ser Duncan the Tall and Prince Aegon Targaryen, alias Egg will lead A Knight of the Seven Kingdoms. Duncan takes on the bald boy Egg as his squire, and he happens to be a Hedge Knight who works in the service of various lords throughout the realm.
