It’s been a long-time theory in Game of Thrones that Jon Snow will be Azor Ahai reborn, the legendary warrior who lived thousands of years ago and saved the world by fighting off the White Walkers. In the books, they are called the Others, who were defeated when the legendary figure used the Lightbringer, a flaming sword that he crafted. The first two attempts of wielding the steel where he tempered it in water and with a lion’s heart, the sword shattered. With a heavy heart, he tried it again and spent hundred days and nights to finish it – called for his beloved wife Nissa Nissa and drove it into her heart.

This history has been awakened by a theory that Jon or Aegon Targaryen is going to kill Daenerys to save Westeros from the wrath of the Night King and his undead army.

Jon Snow is Azor Ahai

When Azor plunged the Lightbringer into his wife’s living heart, her soul combined the steel, and it’s where the flaming sword or the Lightbringer was created.

The followers of R'hllor, the Lord of Light, believe that the legendary warrior will be reincarnated once the White Walkers or the Others attack the world again. We all know that Westeros is in darkness as it has been showcased in “Game of Thrones” Season 7 finale when the Night King and the ice dragon Viserion managed to destroy one great barrier in The Wall.

Jon will sacrifice Dany to save the world

We also know the romance between Jon and Daenerys, which was also featured during “Game of Thrones” Season 7 finale. Theories have it that they will eventually get married, despite the fact that they are both Targaryen, with Dany being Jon’s aunt (although a theory suggests that they are brother and sister). Longclaw, his sword made with Valyrian Steel, can’t defeat the White Walkers as easy as that.

However, to have it tempered, just like what Azor Ahai did, Jon will have to stick it into the heart of the woman he loves to create the sword that will defeat the Night King and his army.

Unfortunately, the woman he loves is no other than Daenerys Targaryen, who has been aiming to sit on the Iron Throne since it was taken from her family during Robert Baratheon’s Rebellion. Another bad news for Dany is that she may not be able to take the throne as she already had visions about this before. One more thing, she is no longer the rightful heir to the throne as what Bran Stark and Samwell Tarly confirmed during “Game of Thrones” season finale. Aegon Targaryen is.

Nope. “Game of Thrones” is not a fairy tale. So, it’s safe not to expect a happy ending.
