The wind is indeed coming from the North and you are wise to head southward, for heading the other direction would be impossible, the north wind is blowing at your back, helping you along, messing with your hair, howling in your ears, still very present as it helps you move along the path of mushy snow you are creating with your spell.

Perhaps it's help is trying to tell you something. Is it possible you could predict something based on its sudden change in direction?

Nothing is random in this place. Try and figure out what the wind is telling you, before you end up a frozen statue in this harsh environment. Your eyes haven't frozen shut yet, but perhaps a warming spell might help. Better hurry, looks like your fingers are turning blue.
