Yep, it's almost time for another season of Game of Thrones. Which is, you know, really awesome and it will be great and yeah yeah yeah. But this teaser is especially foreboding (if very sparsely produced) because of the song, "The Rains of Castamere."
If you've read ahead like a good little nerdlet, you know that music foreshadows the single most shocking event in the series to date. The first episode airs March 31.
