HBO has unveiled a brand new poster for Game of Thrones, which returns with the Season 3 Premiere Sunday, March 31 at 9 PM ET. This poster teases the arrival of fully-grown flying dragons, which were raised by Daenerys Targaryen (Emilia Clarke) in Season 2. While it's unclear if they can breathe fire yet, this dragon depicted in the poster certainly possesses the gift of flight. Take a look at the one-sheet, then read on for more details about the new Season 3 trailer.

The trailer with all new footage is debuting on ABC's Jimmy Kimmel Live! tonight, with an online premiere following shortly thereafter. We'll bring you this new trailer as soon as it's available, so stay tuned.
