Game Of Thrones: 12 Big Questions That Must Be Answered In Season 7

The White Walkers put in their annual appearance in episode 5 this year, showing up to kill the Three-Eyed Raven, and set off the chain of events that led to 'hold the door'. Also in the episode we learnt their origins, and that they were created by the Children of the Forest to help them fight the First Men.

Of course, all this is just a prelude to their eventual invasion of Westeros. We're nearing the endgame, which means we're nearing the big battle of ice and fire.

Given that the show has just two seasons left, the White Walkers will need to get a move on at some point during Season 7. While they can't launch their attack right from the off, they will need to start heading towards the Wall, and could we see a dramatic conclusion that sees the Wall come down and the White Walkers invade?

The Wall contains magic, and there's a good chance it's similar to the Three-Eyed Raven's cave. Bran will need to pass through the Wall to get to Westeros, and he has the White Walkers mark on him - not only giving them a GPS path to the Wall and Westeros, but potentially destroying the magic that holds it together. The alternative to that is the Horn of Winter, or the Horn of Jaramun, which is believed to possess the power to bring down the Wall when blown. Sam found a mysterious horn Beyond-the-Wall, hidden alongside a cache of dragonglass, which is theorised to be the Horn of Winter. Could the horn we blown in Season 7?
