The series’ official Twitter account shared a link to the new website, The Hollywood Reporter explains.
The site, ThreeEyedRaven.com, invites users to sign up for notifications via Twitter or text message. With sign up, members receive a message saying “You now have the power of #The Sight. Keep watch for visions of the future.”
Though HBO declined to give up any hints indicating the meaning of the message, many believe it will eventually lead to a trailer for season 5.
