History of Westeros delves deep into Heart Trees & Weirwoods. As always, we discuss their history while poring over the details to learn as much as possible. We cover everything from tree dreams to blood sacrifice, the power of stumps, Bran’s visions, the cave of the Three Eyed Crow and an assortment of items made from weirwood… and quite a bit more. It’s such a huge topic we can’t even tease it all! Part 2 of our Weirwoods series is out now, view it here.

I never knew that northmen made blood sacrifice to their heart trees.
