'Game of Thrones': Watch the Chilling 'Winter Is Here' Season 7 Trailer

Cersei Lannister (Lena Headey) promises to defeat "whatever stands in our way" in first official, action-packed teaser for penultimate season

HBO released the brooding first full trailer for 'Game of Thrones' Season Seven.

Winter – and the first official trailer for Game of Thrones' Season Seven – is finally here. And if its sneak peek at the upcoming "Great War" is any indication, the penultimate season of HBO's massive hit show is going to be a doozy.

In a series of dramatic proclamations, Daenerys Targaryen (Emilia Clarke) boasts that she "was born to rule the Seven Kingdoms," while current Iron-Throne resident Cersei Lannister (Lena Headey) promises to defeat "whatever stands in our way."

The most chilling prediction, however, comes from Davos Seaworth (Liam Cunningham), who warns that if they don't unite to defeat the Night King, "it doesn't matter whose skeleton sits on the Iron Throne." Elsewhere, the clip showcases the usual mixture of sex, swords and sweeping cinematography ahead for the acclaimed HBO drama.

The network teased the new season in March with a gripping teaser clip that found Cersei, Daenerys and Jon Snow assuming their respective seats of power. The shortened Season Seven – which will comprise seven episodes, down from the typical 10 – premieres July 16th.

HBO has tapped four writers to work with George R.R. Martin on developing new 'Game of Thrones' spin-off series. Watch here.
