HBO has released the first trailer for the fourth season of Game of Thrones.  Plenty happened in season three, but it ended on a bit of anti-climatic note, or at least as anti-climatic as crowd-surfing on a mosh pit can be.  But this trailer is here to remind us that death and destruction are the true rulers of Westeros, and that while "Winter is coming", war is already here.  Also, Jamie Lannister has a new haircut.

Hit the jump to check out the trailer.  Game of Thrones returns on April 6th.

Via HBO.
