Told by the Northmen‪:‬

To the north of this gulf lay the Home of Mist, a dark and dreary land, out of which flowed a river of water from a spring that never ran dry. As the water in its onward course met the bitter blasts of wind from the yawning gulf, it hardened into great blocks of ice, which rolled far down into the abyss with a thunderous roar and piled themselves one on another until they formed mountains of glistening ice.
