HBO has unveiled a mysterious video and website promoting the fifth season of Game of Thrones.

ThreeEyedRaven.com invites fans to sign up to receive "visions of the future," via Twitter or text message, rather than warg-like dreams. In addition to the website link, the Game of Thrones Twitter account also debuted a 10-second video teaser in which we hear Melisandre (Carice van Houten) say, "I see the darkness in you" as we're shown flashes of Arya (Maisie Williams) and her past.

As The Hollywood Reporter notes, the dialogue comes from Season 3, when Melisandre addressed Arya while preparing to leave with Gendry: "I see a darkness in you. And in that darkness, eyes staring back at me. Brown eyes, blue eyes, green eyes. Eyes you'll shut forever. We will meet again."

The fifth season of HBO's Game of Thrones debuts in the spring.
