A Dance with Dragons - Jon XII
“Did they trouble you on your way south?”
“They never came in force, if that’s your meaning, but they were with us all the same, nibbling at our edges. We lost more outriders than I care to think about, and it was worth your life to fall behind or wander off. Every nightfall we’d ring our camps with fire. They don’t like fire much, and no mistake. When the snows came, though … snow and sleet and freezing rain, it’s bloody hard to find dry wood or get your kindling lit, and the cold … some nights our fires just seemed to shrivel up and die. Nights like that, you always find some dead come the morning. ’Less they find you first. The night that Torwynd … my boy, he …” Tormund turned his face away.
“I know,” said Jon Snow.
Tormund turned back. “You know nothing. You killed a dead man, aye, I heard. Mance killed a hundred. A man can fight the dead, but when their masters come, when the white mists rise up … how do you fight a mist, crow? Shadows with teeth … air so cold it hurts to breathe, like a knife inside your chest … you do not know, you cannot know … can your sword cut cold?”
