(CNN) — Is Jon Snow really dead or not?
HBO released a teaser trailer for season 6 of “Game of Thrones,” and it has but whetted the appetite of fans.
In the trailer, the character of the Three-Eyed Raven (played by Max von Sydow) can be heard to say “We watch, we listen and we remember. The past is already written. The ink is dry.”
What follows is plenty of flashbacks, including that now famous scene of the death of popular character Snow, portrayed by actor Kit Harrington.
But it ends with a flash of the character Bran Stark (half brother to Snow) appearing to go into a trance before he says, “They have no idea what’s going to happen.”
“Game of Thrones” is one of the most popular series on HBO and the show is also featured prominently in a tweet from the network on what to watch for in 2016.
Season 6 of “Game of Thrones” premieres in April 2016.
