Trying to catch up, but I don't want to rush it. I rushed reading the books because they are real page turners, so it's hard to recall a lot of the story just a few years later.
So Ned actually sends the letter to Stannis in the show? Or is that wiki entry citing something from the books? I just can't recall the scene where the letter/raven is sent, though it's a small event.
“For God will not permit that we shall know what is to come... those who by some sorcery or by some dream might come to pierce the veil that lies so darkly over all that is before them may serve by just that vision to cause that God should wrench the world from its heading and set it upon another course altogether and then where stands the sorcerer? Where the dreamer and his dream?”
