Greensight is a power that allows a wielder to have dreams of past, present and the future. One of the best examples was the vision Bran had in season 4. Or in the episode 2 of season 6.
Spoiler :
But the latest episode, Oathbreaker, came with so longly waited scene of the Tower of Joy. And we get a new aspect of greensight.
While Bran's dreaming his father heard him calling.
In the March Madness Promo we saw that Night King is able to actually catch Bran while the former is greenseeing.
So what do you think is the real extent of the greensight? It seems there is more to it than just visions. Can they actually affect events that happened or will happened? That would mess a timeline in so many freaking ways. Maybe it's exclusive only to Bran and Raven as they are probably the most powerful seers? Or maybe it shows us that Ned also had talent in it as greensight and wargs are closely tied with First Men. Or maybe it's a new aspect and power of Night's King?
Discuss.
