Top 10 wildest Game of Thrones fan theories ahead of season 8

Bran drove Aerys crazy, built the Wall, is the Night King, did everything important

This one illustrates the problem with introducing time travel to your plot. This theory supposes that Bran Stark, using his powers as the new Three-Eyed Raven, is responsible for virtually every major event in the history of Westeros.

Let’s break it down. We start with the premise that Bran wants to use his power to stop the Night King’s genocidal march south. First, he goes back in time to when Aerys Targaryen is king, and attempts to influence the king to assemble an army and march north to deal with the White Walkers before they become a major threat. Instead, all he does is drive the king mad, and we all know how that turned out. Next, Bran goes back in time and helps the Children of the Forest, the Giants and the First Men build the Wall, acting through the legendary figure Bran the Builder. Then he goes even further back to when the Children created the Night King, attempting to warg into the man he was before the Children have a chance to sow the seed’s of mankind’s undoing. And it’s here where the theory reaches a climax.

As the old Three-Eyed Raven once warned Bran, “[i]t is beautiful beneath the sea, but if you stay too long, you’ll drown.” While attempting to warg into the Night King, Bran becomes trapped in his body, becoming the very monster he was attempting to stop. Recall that the Three-Eyed Raven once told Bran that he would fly. And so he would…as the Night King, atop Viserion.

It’s an interesting theory, and it would certainly change the way we think about the story, but we’d call it a long shot.
