HBO has debuted the key art for "Game of Thrones" Season 4. Following in suit with the recently released character posters, this image reminds viewers "All Men Must Die" -- or Valar Morghulis, in High Valyrian.
It's interesting that HBO opted for the three-eyed raven to be the main imagery for Season 4. As fans recall, the magical creature is what Bran, Jojen and Meera are heading toward north of the Wall. Bran has seen the three-eyed raven in his crow dreams, and it's helping him unlock his warg abilities.
In previous years, HBO used the Iron Throne as the key art for Season 1, a fist clutching a crown for Season 2, and Daenerys' dragons for Season 3. Considering how integral all those objects have been in each season they were used for, consider this a clue of what viewers should keep an eye on in Season 4.
"Game of Thrones" Season 4 premieres April 6 at 9 p.m. ET/PT on HBO.
