We're less than three months away from the return of "Game of Thrones," which takes on the epic events of George R. R. Martin's novel, "A Storm of Swords," in Season 3.

In preparation for the show's much-anticipated premiere, HBO has released a tantalizing new promo which invites fans behind the scenes of the new season, previewing returning characters like Tyrion Lannister (Peter Dinklage), Robb Stark (Richard Madden) and Margaery Tyrell (Natalie Dormer), as well as newcomers like Mance Rayder (Ciaran Hinds) and Lady Olenna Tyrell (Diana Rigg).

The trailer also offers a glimpse at the city of Astapor, where Daenerys Targaryen (Emilia Clarke) will spend much of the season, and teases Jon Snow's (Kit Harington) journey north of The Wall, following his capture by the wildlings in Season 2.

Excited yet?

"Game of Thrones" Season 3 premieres Sunday, March 31 at 9 p.m. EST on HBO.
