Why hasn’t the news of the White Walkers spread at least as rumors yet? The Night’s Watch is now officially preparing for them, Stannis too, the Wildlings argreed to play along with the ‘kneelers’ because of them, a few Northern nobles have shown up at the Wall, yet somehow nobody let word out that the monsters of legend are real and coming for them? Even if the guests at the Wall don’t believe it, wouldn’t the fuss about them at least cause some gossip?
