What in the heck even are these things? These skeleton-zombie beasts known as Wights are related to White Walkers, but with far less flesh, more speed, and more murderous tendencies. They attack Bran's little traveling group on the way to the three-eyed raven and, in the process, kill Jojen Reed. Apparently magic staves them off, but how long until we see them again? Shudder.
