Season 3 of “House of the Dragon” introduces viewers to Tumbleton, a town rooted in George R.R. Martin’s “Fire and Blood.” Though deeper insights remain behind a paywall, its appearance suggests a pivotal new storyline developing in Westeros.

Set before the events of “Game of Thrones,” “A Knight of the Seven Kingdoms” takes viewers to an earlier chapter of Westeros. Unlike the original series, this new story forgoes dragons, offering a fresh vantage point on the Seven Kingdoms.
