Forget winter, folks. HBO has a new warning for the fans of Game of Thrones and the character on it:

War is Coming.

So teases the just-released poster for season two of this incredible drama, which debuts on April 1. Similar to the set of premiere photos that hit the Web last week, the teaser gives little away, but the mystery is a large part of the appeal. A battle for the Iron Throne is about to be underway. What else does on need to know?!?
