SPOILER ALERT! After the shocking Season 5 finale of HBO's Game of Thrones, one of the many questions left unresolved is whether or not Kit Harington's Jon Snow is really alive or dead. The Night's Watch commander was savagely attacked by his "brothers," who left him for dead during the finale, Mother's Mercy. While we likely won't get any solid confirmation about Jon Snow's fate until next year, the show's official Twitter account has released the first Season 6 poster, featuring a cryptic image of Snow, while teasing that the new season will debut in April.

There has been plenty of evidence that supports /game-of-thrones-season-6-kit-harington-jon-snow/Kit Harington's Jon Snow being both alive and dead. Back in September, new photos surfaced that showed Kit Harington on the Northern Ireland set. Some have speculated that the Red Priestess Melissandre (Carice van Houten) could use her supernatural powers to bring Snow back from the dead, but series creators/showrunners David Benioff and D.B. Weiss have said on numerous occasions that Snow is really dead. Author George R.R. Martin has even teased in the past that this beloved character isn't really dead, but we still don't know for sure, since fans are still waiting for his sixth book in the series, The Winds of Winter, to be published.

This new poster also teases that Game of Thrones Season 6 will debut sometime next April on HBO, although an exact release date wasn't given. Unless George R.R. Martin manages to get his sixth book published before April 2016, Season 6 will be the first season that will debut before the latest book has arrived. HBO and the producers have been extra secretive as production continues this season, with the show eschewing its tradition of revealing new cast members and characters at their annual Comic Con panel, but we do know a number of new actors who have come aboard so far.

New characters include Ian McShane in an unspecified role, Pilou Asbæk, who has been rumored to be playing Euron Greyjoy, the uncle of Alfie Allen's Theon Greyjoy and Max von Sydow as the Three-Eyed Raven. Richard E. Grant and Essie Davis are portraying members of a theater troupe who are putting on a play about famous figures in Westeros, with James Faulkner, Samantha Spiro and Rebecca Benson portraying the father, mother and sister of Samwell Tarly (John Bradley). Most recently, we reported that Spartacus: Vengeance star Joseph Naufahu has come aboard, rumored to be playing a Dothraki warrior.

This season will also mark the return of Isaac Hempstead-Wright's Bran Stark and Kristian Nairn's Hodor, who are just a few characters set to return after a lengthy hiatus. Brynden Tully, a.k.a. The Blackfish, (Clive Russell), who was last seen at the infamous Red Wedding, will be back, along with Gemma Whelan's Yara Greyjoy, Theon Greyjoy's sister, who hasn't been seen since the Season 4 episode The Laws of Gods and Men. While we wait for more details regarding Season 6, check out this new poster, and chime in with your Jon Snow theories.
