The High Valyrian saying "valar morghulis" is the slogan for the upcoming fourth season of "Game of Thrones," translating to "all men must die," which is emblazoned on the official key art just released by HBO featuring a three-eyed raven apparently made of swords. It's a fitting theme for a series known for its high body count -- the new season premieres on April 6th.
