With fans still reeling from the death of Jon Snow (Kit Harington) in the Season 5 finale of Game of Thrones, HBO certainly hasn't made it any easier to mourn. Last week, the cable network released the first poster for Season 6 of Game of Thrones, slated to debut in April, which featured the bloody face of Jon Snow. Today, HBO has debuted the first trailer, which prominently features Jon Snow from the epic Battle of Hardhome, along with several other iconic moments from the show's five season run. Perhaps most importantly, though, this trailer features the voice of returning star Isaac Hempstead-Wright as Bran Stark, along with Max von Sydow as the Three-Eyed Raven.

At the end of Season 4, Bran Stark finally reached the Weirwood Tree and met the elusive Three-Eyed Raven. Since his story had essentially caught up to the George R.R. Martin novels, both Bran and Hodor (Kristian Nairn) sat Season 5 out, as Bran started his training with the Raven. We reported in August that Max von Sydow has been cast as the Three-Eyed Raven, who has been training Bran to hone his "greensight," which allows him to see the past, present and future. While we don't get to see new footage of Bran or the Raven, the footage ends with a cryptic warning from Bran: "They have no idea what's going to happen."

This message could have a double meaning as well. While we assume that Bran is referring to the people of Westeros, it could also be for Game of Thrones fans themselves. Season 5 wrapped up all of the main story lines told in George R.R. Martin's first five novels, and since we don't know when the final two novels will be published, fans have been left in the dark about what will happen in Season 6. HBO hasn't announced a specific premiere date yet, but both last week's poster and this new trailer reveal that the show will return sometime in April.

As for Jon Snow, 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 season will mark the arrival of several new cast members, such as Ian McShane in an unspecified role and Pilou Asbæk, who has been rumored to be playing Euron Greyjoy, the uncle of Alfie Allen's Theon Greyjoy. 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. While we wait for more details about Game of Thrones, check out the new trailer for this highly-anticipated season.
