10 Facts About Westeros Game Of Thrones Won't Tell You
8. White Walkers Took 2000 Years To Get An Army Together
What we know from a small scene in the HBO series is that the Children Of The Forest created White Walkers because they were at war with the First Men. In this scene, one of the Children tells Bran “We were being slaughtered. Our sacred trees being cut down. We needed to defend ourselves.”
When Bran asks “From who?” the reply comes: “From men.” So the Children plunged a dragonglass dagger into the heart of a man, creating the first White Walker. But something doesn’t add up with that timeline, and it’s the fact that The Long Night – the time when White Walkers first rose up and had to be defeated by the Children and the First Men – didn’t happen until 2000 years after the peace treaty was signed.
So what gives? This is where thing gets tricky and the TV show will never acknowledge it because it’s easier to just gloss right over the timeline and pretend everything makes sense. But if the Children Of The Forest really created White Walkers to defend against the First Men, then why did they only come around two millennia after the fight ended?
The only possible explanation to this question is that the Children Of The Forest lost control of their greatest weapon and the White Walkers set out into the North on their own. From there they slowly made wights, created new Walkers, and finally after thousands of years they were ready to attack.
By the time the Long Night came, peace was at hand, and as a result both the Children and the First Men had to come together to fight the White Walkers in order to save all life on Westeros.
