As part of the Apple TV and HBO announcement, iTunes released this exclusive trailer online.

The Houses of Westeros are but spokes on a wheel, forever turning. First up, then down. The latest “Game of Thrones“ trailer positions Daenerys Targaryren as thinking she’s above this cycle…but is she? How long can you be the hero before you become tyrant?

Power is nothing but shifting sand in Westeros and beyond. In the struggle to stay on top, who will be the victor?

"Game of Thrones" premieres on April 12, 2015 on HBO.
