The cold tunnel through the Wall at Castle Black makes Jon Snow think of an ice dragon. She said that the breath of the Ice Dragon was very cold. Old Nan told tales of ice dragons to the children of Lord Eddard Stark. Maester Margate has suggested that the tales of Cannibal Bay may be explained as distorted reports of ice dragon activity. The Ice Dragon is a constellation whose blue eye points north. Reportedly, they are far larger than the dragons of Valyria and are made of living ice, with eyes of pale blue crystal, vast translucent wings, and breath of cold. Ice dragons are said to roam the Shivering Sea and the White Waste.
