'Game of Thrones': Dragons, White Walkers, Battles Dominate Season 7 Trailer

"For centuries our families fought together against our common enemy. Despite their differences. Together," Jon Snow says in latest preview

With less than a month before the seventh season of 'Game of Thrones' premieres, HBO has unleashed a new trailer warns "Winter is here."

With less than a month before the seventh – and second-to-last – season of Game of Thrones premieres, HBO has unleashed a new trailer that once again warns "Winter is here."

The two-minute trailer opens with the denizens of Westeros – including Daenerys Targaryen (Emilia Clarke), Cersei Lannister (Lena Headey), Tyrion Lannister (Peter Dinklage) and Sansa Stark (Sophie Turner) – seemingly preparing for what promises to be an epic battle not just for the Iron Throne but the very survival of all seven realms.

"For centuries our families fought together against our common enemy. Despite their differences. Together," Jon Snow (played by Kit Harington) says in voiceover in the trailer. "We need to do the same if we're gonna survive. Because the enemy is real."

In the second half of the trailer, the battle is at hand, with crows, arrows and dragons in flight while armored men face the dreaded White Walkers, the "common enemy" Snow spoke of.

The trailer concludes with Sansa Stark ominously warning, "When the snows fall and the white winds blows, the lone wolf dies but the pack survives."

Game of Thrones' seventh season arrives July 16th.
