Warning: winter is here, and so are the spoilers.
Who the Wun Weg Wun Dar Wun is Azor Ahai? It's Daenerys, right? No, it's Tyrion! It's not Samwell Tarly, is it? Or could it possibly be the subject of a staggering amount of Game of Thrones theories, Jon Snow?
Fans know the Prince or Princess that was promised has come, though that person's identity remains unknown. But there is a very compelling Rhaegar Targaryen fan theory circling the Internet that claims Daenerys’s late brother is Azor Ahai, and that the one and only Jon Snow is Lightbringer.
Before you dive into this theory, there are a few questions to answer first. What is Lightbringer? Is it a sword, or could it be a specific person? If you believe the stories hardcore GoT fans tell, Lightbringer is everyone's favorite glowering, know-nothing Night's Watchman. Here is the Jon Snow fan theory to end all Jon Snow fan theories, tying together his mysterious past with his (hopefully) legendary future.
Over 8,000 years before the main action of GoT, during the Age of Heroes, the Known World fell into a long, dark winter. During that time, the Others marched on humanity with their army of the dead - basically, exactly what is happening now in Westeros. The White Walkers drove the First Men and the Children of the Forest south until The Last Hero joined them, and with the use of dragonglass, they drove back the Others in the Battle for the Dawn.
The Last Hero lived during the age of the Long Night, and is believed by many to be Azor Ahai. This figure of prophecy forged the sword Lightbringer by plunging it into the heart of his wife, and used it to defeat the Others. This legend is espoused by the followers of R'hllor, the Lord of Light.
Lightbringer is said to be the legendary sword of Azor Ahai. It took him three attempts to forge it; ultimately, he had to plunge the sword into his wife Nissa Nissa's heart to complete the magical creation, her soul lending the sword its magic. But, then again, Lightbringer could also describe a person, depending on one’s interpretation of the prophecy.
There’s really no doubt about this at this point. The evidence is overwhelming, so much so that it’s almost unnecessary to make a case, but here is the definitive proof:
In Season 6, viewers see a flashback at the Tower of Joy where Ned Stark finds his dying sister Lyanna and accepts her son, vowing to claim him as his own. If the baby’s true parentage were known, i.e., that he’s the son of Rhaegar Targaryen and thus heir to the Iron Throne, he would be in grave danger. As the camera settles on the baby’s face, the flashback fades and the show returns to a shot of Jon Snow’s face.
