The biggest battle that Game of Thrones has ever seen is going to hit screens in the next few months, as the living and the dead fight it out for the future of Westeros. This is a showdown that has been teased since the very first season of the series, when the White Walkers were still seen as a myth, and not a legitimate threat. Now, the White Walkers are going to be facing off against Jon Snow and his army, and there may be only one person who can save them.
