Here's everything we know about the White Walkers so far...
*If you haven't watched season 7, look away now*
Who are the White Walkers?
The White Walkers in Game of Thrones are zombie-like creatures that pose a supernatural threat to humankind.
Author George R R Martin describes them as "gaunt and hard as bones, with flesh pale as milk" in the books, and frequently refers to them as "the Others".
While the White Walkers have been kept at bay behind The Wall for some centuries, they have now broken down that barrier with Daenerys' undead dragon, Viserion.
The White Walkers are led by the Night King, who was the first White Walker to be created. Their army is then referred to as "Wights".
So far, we've learnt that they can be defeated with dragonglass, Valyrian steel and fire. We also know they can't swim.
The Night King, however, appears to be immune to fire, as in the season 7 finale, we watch him walk through the flames unharmed.
We've also seen previously that killing the White Walker simultaneously wipes out all the Wights that Walker created.
So, there's the theory that killing the Night King will destroy all of them, as ultimately, it was him who started turning people into Wights.
Why did the Children of the Forest create the White Walkers?
Cast your minds back to season 6 of the show, when Bran, Meera and Hodor (RIP) entered the magical cave where the Children dwell.
They came across the previous Three-Eyed Raven, who then taught Bran to follow in his footsteps.
It was during one of Bran's visions that he saw the head Child, Leaf, create the first ever White Walker.
She does so by driving a dragonstone dagger into the heart of a human man. His eyes then turn that chilling blue colour, before he transforms into the Night King.
Leaf then explains that the Children of the Forest created the White Walkers in order to help them defeat the First Men, whom they were at war with.
The First Men were destroying the sacred forests, and the Children believed they needed stronger protection.
Sadly, the White Walkers turned against the Children, and became the fearsome force we've all come to know now.
