This Game of Thrones ending theory is the most convincing yet

We're a matter of weeks away from the premiere of the final season of Game of Thrones, and the fan theories are getting out of control.

With the show's stars and producers giving us nothing but crumbs over the past two years, fans have been left to their own speculative devices to guess how this fantasy epic is going to end.

While some of the theories are pretty outlandish and hard to believe, a Reddit thread has predicted how the White Walkers will be defeated.

And, we'll be real with you, it sounds weird as hell. But it has the legs to be legit.

A Reddit user has pointed out the glaring clue is in the title of the book saga, A Song of Ice and Fire, saying it could mean an actual song is the solution to defeating the White Walkers.

Ridiculous right? But hear it out.

A while ago author George R.R. Martin said the answer to everything has been right under our noses the whole time, giving the song theory some serious weight.

This is how the user explained it:

"The only confirmed ways to kill the White Walkers involve magic, this includes dragon glass which are magical (confirmed by G.R.R. Martin) used by the Children of the Forest, Valyrian steel which are infused with Valyrian magic, and the fire from the dragons, which are magical creatures," the thread reads.

"First of all, we know that there is the prophecy of the prince that was promised, which involves a song. This means that there is an actual song, but as to what this song is, we don't know."

The Prince That Was Promised (also known as the Lord's Chosen, the Son of Fire and the Warrior of Light) is a prophesied saviour in the religion of the Lord of Light.

The prophecy suggests he would be born "amidst salt and smoke" and pull a sword from flames, which would be used to combat an "impending darkness".

Now back to the fans theory:

"Perhaps there is a sort of magical song, literally, which could kill the White Walkers entirely, and perhaps even Rhaegar knew what it was. There are so many references to Rhaegar singing with his harp, and Rhaegar is first and foremost a singer, he only learned how to fight due to this song, whatever it is.

"However, in order for the song to be effective, requires the singer themselves to be infused with both fire magic and ice magic. In the show, we know that Targaryens have a special connection with fire, whereas the Starks are said to have a connection with ice, or broadly, winter, thus, these two bloodlines are infused with fire magic and ice magic.

"This does not invalidate the Azor Ahai, or the Nissa Nissa theory, because it's clear that sword fighting is a necessary component to defeating the White Walkers, but since there is at least dozens of White Walkers, the likelihood of killing all of them is difficult, in fact during the Long Night, not all the White Walkers were killed, how they were defeated remains a mystery.

"Perhaps this is where the song, whatever it is, comes in, and the person imbued with the blood of fire and the blood of ice who sings this song will destroy the White Walkers finally."

Not so ridiculous anymore, huh?
