The White Walkers are leaders of an ice zombie horde known as “wights” seemingly intent on destroying the world of men. They come from the far North, deep beyond The Wall, but have been organized under the rule of the Night King and are making their way south to Westeros as we speak.

Not that anyone besides the wildings, Jon Snow, the Night’s Watch, and Ser Davos are taking the threat seriously, though. In the first trailer for Season 7, we hear Davos tell someone: “If we don’t put aside our enmities and band together, we will die. And then it doesn’t matter whose skeleton sits on the Iron Throne.” Listen to the man, dammit!
