HBO’s Game of Thrones has been referencing the Prince that was Promised for several seasons already. Fans of the show have been hedging their bets on which character this could be. It is believed that the Prince that was Promised will be the reincarnation of the legendary warrior Azor Ahai.
After Jon Snow’s resurrection, many fans started to think that he was the prophesized prince. However, recent events in Season 7 hinted that the prince could be a woman, given that High Valyrian language (in which the prophecy was delivered) is not gender specific.
In particular, fans believed that it could be Daenerys Targaryen and not Jon Snow.
Daenerys' is not Azor Ahai
Based on the theory, Dany’s defeat by water when Euron Greyjoy ambushed her fleet and took two of her allies (Yara Greyjoy and Ellaria Sand) could be parallel to Azor Ahai’s failure by water. Her failed raid on Casterley Rock, the stronghold of the Targaryens, could be the equivalent of the failure via lion’s heart as the Lannisters’ sigil is a lion. Some fan theories believe Drogon being stuck by an arrow during the loot train attack already counts as the third attempt.
However, some believe that the return of Ser Jorah, who has been in love with Daenerys since the earlier seasons, will be the key to unleashing Lightbringer.
Fans theories believe that he will sacrifice his life to make the prophecy come to life.
Dany's true purpose
A fan theory posted on Facebook Page "Game of Thrones 101" believes that Dany is not the Prince that was Promised. However, she will be instrumental in fulfilling the prophecy. The fan theory posited that Game of Thrones Season 8 would revolve around the death of Daenerys Targaryen, the Battle of the Last Hearth, and the return of Azor Ahai.
The theory indicated that Jon Snow (now Aegon Targaryen) and Daenerys would march their armies to the Last Hearth just as the Army of the Night King approaches. The Dothraki, the Unsullied, the northerners and the Knights of the Vale will brace for the biggest threat that they have faced in their lives with the fate of the living at stake.
The theory posits that Jon will mount Rhaegal, the dragon that was named after his father Rhaegar while Dany will ride Drogon to engage the Night King (who is riding Viserion) in an aerial battle. As Viserion succumbs to the fire attacks of his brothers, Jon engages the Night King in battle, but Longclaw is broken in two. Daenerys will shield Jon with her body and sustains a critical wound. Before she dies, the Red Woman arrives and gives Jon the broken blade and tells him to thrust it into Daenerys' heart.
The Red Woman will explain that the Lord of Light did not will for Daenerys to live, but her death could serve a purpose. Even though Jon did not want to do it, it was Daenerys who plunged the sword into her heart to bring Lightbringer to life.
While plausible, fans still need to wait for either "Game of Thrones" to complete its final season, or George R.R. Martin to release his final two books before the theory is confirmed. HBO has yet to announce whether the final season will air on 2018 or 2019 but after the cliffhanger Season 7 finale, there are still many more theories that fans have yet to discuss.
