Game Of Thrones Prequel: 10 Legendary Characters We Hope To See
5. Leaf And The Children Of The Forest
The Children of the Forest are the original inhabitants of Westeros, along with Giants. They have been dismissed as make believe by just about everyone in Westeros save for Bran Stark and Meera Reed considering they're the only living people that we know of that have seen them. When the First Men came over across a now vanished land bridge from Essos to present day Dorne, they immediately warred with the Children until the Pact was made to defeat the Walkers. Now that since that's been brought up...
We do know thanks to Bran's vision quest with the Three Eyed Raven that it was the Children who created the White Walkers in the first place as a weapon to fight men, which as we know, eventually backfired. Thus, the Pact was formed.
What's interesting here is that Leaf was the particular child that created the Night King and would thousands of years later sacrifice herself to ensure that Bran and Meera escaped the tree of the Three Eyed Raven from the White Walkers and that Hodor held the door. Due to this, there is a chance that Leaf could be the only character to appear in both Game of Thrones and the prequel.
