As fans impatiently wait for Season 5 of Game of Thrones to debut sometime next spring, HBO has released a very brief teaser trailer with snippets of new footage. The video was released on the show's Twitter page earlier today, which also leads to the new website Fans can sign up to "receive visions of the future" from this upcoming season, through either a Twitter account or text messaging. For those who aren't caught up with the series yet, there will be some slight spoilers below, so read on at your own risk.

The footage and the website itself alludes to the raven that Bran Stark (Isaac Hempstead-Wright) finally encountered in the Season 4 finale, after seeing this bird in his visions. However, the footage does not show Bran, who is sitting out this season because the show has caught up to his story from the George R.R. Martin. Instead we get a brief glimpse at Arya Stark (Maisie Williams), with a voice stating "I see a darkness in you."

Production is currently under way on the new season, which will feature the first ever flashback sequence that will serve as the opening scene in the Season 5 premiere. HBO hasn't announced when the new season will debut yet, but it will likely debut in either late March or early April.
