There’s an ancient prophecy established in the Lord of the Light religion that purports a savior “born amidst salt and smoke” will pull a sword called Lightbringer from the flames to combat perpetual darkness. He or she will “have a song…of fire and ice.” It’s believed that this savior is the reincarnation of a hero named Azor Ahai, a warrior who lived thousands of years ago in Essos.
The prophecy was first mentioned in the second Game of Thrones novel A Clash of Kings, and though this person is most frequently called “The Prince That Was Promised,” they’re also sometimes known as “The Prince Who Was Promised,” “The One Who Was Promised,” the “Lord’s Chosen,” the “Son of Fire” and the “Warrior of Light.”
This person is mostly believed to be Jon Snow (Kit Harington), Daenerys Targaryen (Emilia Clarke), Samwell Tarly (John Bradley), Tyrion Lannister (Peter Dinklage) or Bran Stark (Isaac Hampstead-Wright) in the series, but there’s one little hang-up that I can’t shake. If the “Prince That Was Promised” is a person, then why aren’t they most commonly referred to as the “Prince Who Was Promised.”
