HBO finally confirmed what the fans have dreaded all along. "Game of Thrones" won't be back until sometime in 2019. The wait will be long and painful, but it will be worth it because according to pretty much everyone Season 8 will be the greatest thing that's ever aired. So all in all, the fans will have more than enough time to speculate on what's going to happen in the final season.

The clues are there and so is George R. R. Martin's "A Song of Ice And Fire" book series on which "Game of Thrones" is based. And despite the fact that the show and the books couldn't be any more different at this point in the story, the showrunners and George R.

R. Martin confirmed that the ending would be pretty much the same. So using the "A Song of Ice and Fire" novels as evidence to support the show theories is absolutely legit, at least when it comes to the ending of the series.

Now with that out of the way, let's shift our focus to today's theory that has to do with a certain prophecy or rather its misinterpretation. So let's delve into this.

The Prince That Was Promised prophecy

According to "Wiki of Ice and Fire," the Prince That Was Promised is a prophesied hero, a savior of mankind, who would be born under a bleeding star "amidst salt and smoke" to wake dragons out of stone. This prophecy was written in High Valyrian, a gender-neutral language, so this prince might be a princess as well, as we learned in "Game of Thrones" Season 7.

Let's not forget that the Prince That Was Promised was also mentioned in Daenerys' the House of the Undying vision from "A Clash of Kings" where she saw her brother Rhaegar talking to Elia Martell (his wife) about their newborn son Aegon.

He is The Prince That Was Promised, Rhaegar said, and his, is the song of ice and fire.

In the books, Melisandre uses the term the Prince That Was Promised and Azor Ahai interchangeably which seems to imply that they are one and the same. But as we all realized by now, Melisandre really isn't a reliable source of information as she often misinterprets her visions. With that in mind, it stands to reason to believe that the whole Lord of Light religion was based on the misinterpreted prophecy. Which brings us to today's theory.

The truth behind the Prince That Was Promised prophecy

According to YouTube channel Talking Thrones, the Prince That Was Promised prophecy could be just a play on words, meaning that this prince isn't a hero reborn, but someone promised to the Night King.

In his video, Talking Thrones shared our opinion that the Last Hero actually made the pact with the White Walkers [VIDEO] which ended the first Long Night and there is a special someone who was promised to the White Walkers.

And that someone is none other than Jon and Daenerys' baby, the child of ice and fire. This would explain the reason why the Night King is attacking now after all these years and why he didn't kill Jon Snow when he had a chance.

Does this theory make sense?

While Jon and Daenerys' baby being the Prince that Was Promised as a child of ice and fire is by all accounts a pretty solid theory, there are some arguments against it. For example, if the right bloodline is required, wouldn't it be more fitting that the Prince That Was Promised is Jon Snow? He is, after all, a half Stark and a half Targaryen being the child of Rhaegar and Lyanna, while this baby is just one-quarter Stark. However, Jon Snow is not a baby, and we saw only babies being converted into White Walkers. But then again, the man tied to the tree wasn't a baby either when he was turned into the Night King [VIDEO].

With all this being said, we don't think that this theory will come true, but you can watch Talking Thrones' video down below for more details and then decide for yourself.
