The Arrival of "the Prince That Was Promised"
As we all know, Winter is coming in the Game of Thrones universe. It's a phrase that's been uttered more than a handful of times since the show's premiere. It's more than just a Winter, though. It is believed cold darkness will fall on the world once more, and the Others will saturate the Seven Kingdoms of Westeros. We've seen indications of this bleak era on the show, most notably in the battle at Hardhome on season five, where we witnessed the rise of the legendary Night's King.
According to prophecy, Azor Ahai will also return, reborn as "the Prince That Was Promised." In this time where darkness casts its shadow on Westeros, it is said that a warrior will be born "amidst salt and smoke." At some point, he will rise and "draw from the fire a burning sword." This sword will be the Lightbringer, and the hero who wields it will become Azor Ahai incarnate. Once again, he will defeat the Others and beat back the darkness.
