It was only a few seasons ago that we watched Bran, Ned Stark's son, as he travelled north to meet his mentor. At the end of Season 4, physically challenged Bran, carried by Hodor, mets the Blood Raven, and that was the last of his screen time. However, the latest teaser image released by HBO hints at Bran's role in Season 6 of "Game of Thrones". A brief glance at the image indicates that Bran is mobile and perhaps doesn't need his trusted companion Hodor's help. 

To be sure, both teaser updates released so far predict the Starks will play a huge part of the plot in the upcoming season of the HBO fantasy series. Jon Snow (Kit Harrington) and Bran Stark's (Isaac Hempstead Wright) storylines will, in all probability, determine the fight against the white walkers. Fans of the show would remember that at the end of the teaser video, Bran Stark says, rather ominously: "They have no idea what's going to happen."

In Season 6, Bran, the second-youngest of the Starks, will be more skilled in controlling his powers. In all probability, he will have mastered the art of peeking into the future, but it remains to be seen if he can control it in any way.

In a recent interview with Entertainment Weekly, actor Hempstead Wright said his character Bran would have the ability to look into the past, present and future and piece information together. "He's now discovering how crucial he could be in the Great War. It's quite Inception-y."

Part of understanding the future could mean the apocalyptic fight against the shadowy white walkers. Nevertheless, will Bran's powers be limited in the war against the zombie-like creatures? Who could thwart his effort?

A recent post by a vlogger hints that Bran's mentor, the Blood Raven, could in fact be part of the white walkers. This is due to a vision Melisandre (Carice Van Houten) has. Furthermore, the Blood Raven (Max von Sydow) also has the power to change his face like Jaqen H'ghar; he can get into the skin of another person or animal, and can see the future as well. In the books, he tells Bran to embrace darkness and eliminate the possibility of light in his life.  

"Game of Thrones" Season 6 is expected to premiere in April 2016 on HBO.
