'Game of Thrones' Season 4 Trailer: The War Is Not Won

Winter is already here, but the fourth season of "Game of Thrones" is coming.

HBO released the first trailer for "Game of Thrones" season four tonight, revealing the upcoming struggles of the people of Westeros as the war for the Iron Throne continues.

The trailer begins with everyone's least favorite boy king, Joffrey, proclaiming that he won the war that we saw play out in the third season. But as Jaime Lannister informs him, "The war is not yet won."

That's definitely true, considering that the trailer shows Danaerys continuing to build her forces with her dragons and her newly acquired army. But advice from Jorah warns her about the grey areas between good and evil that war presents.

Will Dany end up becoming evil in her quest for the throne? And what will become of Tyrion, who can be seen being led up to the throne in shackles, escorted by guards?

Meanwhile, the White Walkers continue their advance, with only Jon Snow in their way.

The fourth season of "Game of Thrones" premieres Sunday, April 6 at 9pm on HBO.
