Wow. That's a lot of heads in the 'Hall of Faces'. Send a raven indeed. 

In the last few hours, Game of Thrones official twitter has gone into overdrive, posting and retweeting the following posters for Season 6. In short "Anyone can be killed..." And before you ask, yes, Jon Snow is there (although we're all more concerned if he can come back to life...)

Of course, he's not the only one. Clap your eyes on this lot.

Season 6 premieres on April 24
