'Game Of Thrones' Season 5 Teaser Hints At Arya's Future

HBO has launched a new social media campaign that will be giving curious fans a glimpse at what is in store for season five of Game of Thrones.

By signing up at ThreeEyedRaven.com, fans will receive notifications via text message or Twitter direct message, with the first message reading " "You now have the power of #TheSight. Keep watch for visions of the future."

As fans of the book know, the Three Eyed Raven and The Sight are linked with the idea of visions. Fans who sign up on the website are granted "the sight" and will be given special glimpses at the upcoming season.

First up, and available for even those who haven't signed up, is a brief teaser trailer featuring Arya.

Most of the images are taken from previous seasons, but they point towards Arya's future.

Spoilers ahead. Read at your own risk!

We know at the end of season four Arya turns in her coin and is traveling across the sea to Braavos. We see images of that in the trailer, along with Arya taking up a sword and a quick look at a mysterious door. Book readers already know what Arya will find in Braavos -- the House of White and Black, where she will train to become a face-changing assassin like that of Jaqen H'gar.

She will also go blind in the process, at least for a time. Could the door in the trailer be the House of White and Black? Are these visions possibly coming from Bran himself? We know Bran won't be in season five as he trains under the Three Eyed Raven north of the Wall. What character's future will be teased next? It's all unclear, but HBO will no doubt be releasing more glimpses at the show's future as we slowly approach season five's debut in the spring of 2015.

Better yet, fans may get a hint of events to come by playing Telltales upcoming episodic Game of Thrones video game, which is set during season four and follows a noble house sworn to the Starks. The first episode is on schedule to release before year's end.
