"The Long Night is coming," Melisandre tells Daenerys of why she's come to her. "Only the prince who was promised can bring the dawn."
It's not the first time we've heard about "The Prince That Was Promised" on Game of Thrones. Melisandre once believed the title referred to Stannis Baratheon, and later to Jon Snow. Now, it appears that Daenerys has something to do with it, too. And with the revelation that "prince" has no gender in Valaryian, might Dany be the the princess who was promised? The one to end the Long Night and restore peace to the world?
"I believe you have a role to play," Melisandre admits. "As does another: the King in the North, Jon Snow."
So, what exactly is the Prince That Was Promised prophecy and why is it so important? Is it possible that it refers to both Daenerys and Jon? Here's a brief history of the Long Night, Azor Ahai, the Prince That Was Promised, and what he or she could mean for the future of Westeros.
