Going through my list of possible foreshadowing. The fall of White Harbor.
Next to the high seat, Ser Marlon Manderly gave a snort of disdain. "It has been centuries since White Harbor has seen any wildlings, and the ironmen have never troubled this coast. Does Lord Stannis propose to defend us from snarks and dragons too?" (Davos III, ADwD)
There are thousands of wildlings south of the Wall, the ironborn have been emboldened by their new king. The Others are real. So are dragons. #ASoIaF
