1 Winter is coming
Game of Thrones and its new spin-off, House of the Dragon, take place in the Seven Kingdoms of Westeros, a turbulent continent loosely inspired by the feudal societies of medieval Europe – think knights on horseback, stone castles and all-powerful royal dynasties making life miserable for everyone else. But this fantasy world has one notable USP: in Westeros, seasons can last for years, making the arrival of winter a terrifying, potentially apocalyptic prospect. Not least because (by the time of Game of Thrones at least) it’s ruled by a Night King who can reincarnate the dead as zombie-like “White Walkers”.
