'Game of Thrones' Season 5 Teaser Trailer Proves Winter is Coming, For Real This Time — VIDEO

You never know when HBO is going to drop a bomb like the teaser trailer for Game of Thrones Season 5. Well, spoiler alert: It's here, and it's as mysterious and eery as ever. The teaser is about 16 seconds long — yes, 16 seconds. It features Sansa, Tyrion, Cersei and a lot of fantastical and non sequitur elements like water, birds, windows and a three-eyed raven, a reference to the bird that Bran Stark has sought since Season 1. Take from it what you will.

Season 5 of the fantasy epic promises even more twisted plot lines and unfortunate fan favorite deaths. Those who have read the hearty series however, know exactly when and who will perish. The last teaser for Season 5 featured young Arya Stark on her journey to Braavos, and it seems she's well on her way to becoming one of the fiercest fighters in the whole series, despite her short stature and young age.

So when will HBO drop a full-fledged Game of Thrones Season 5 trailer — you know, one that's more than 30 seconds in length? Who the heck knows. Until then, you can attempt to unravel the clues in this teaser.
