What we do know for sure about the Three-Eyed Raven is that he is a Greenseer, gifted with the ability to see the past, present, and future and communicate through dreams. Greensight is more common with the Children of the Forest, but some humans, like the Three-Eyed Raven, also have this ability.
Although we don't meet the Three-Eyed Raven on Game of Thrones until season five, his presence hangs over the entire series. When Bran falls from the tower and slips into a coma, the Three-Eyed Raven appears to him as a bird infiltrating his dreams. Later, Bran hears his voice coming from a weirwood tree, directing him to go north.
