Winter is here.
The second trailer for the seventh season of Game of Thrones has been released - and it's even more chilling than the first.
The two-minute video opens with Sansa Stark (Sophie Turner) walking through the snow as her mentor Littlefinger (Aidan Gillen) advises: "Don't fight in the North or the South. Fight every battle everywhere, always - in your mind."
Set against series composer Ramin Djawadi's haunting score, Light of the Seven, epic battle scenes filled with fighting and flames glide across the screen.
The trailer ends on a solemn note with Sansa Stark saying:
"When the snows fall and the white winds blow, the lone wolf dies - but the pack survives."
Game of Thrones returns to HBO July 16.
