A blizzard of hell, upon the night of Hearth's Warming Eve. Sent purely by accident to the small town of Ponyville. Although it would mean a snow heaven for the little ponies of the quaint town for the next morning, it wasn't exactly heaven through the night.

A lone mare, whose trust is scarce, stuck within the howling winds. Her wings frozen. Her legs numb. Slowly falling into a freezing slumber.
Until a friend came in her time of need, and warmed both of their hearts with the spirit of Hearth's Warming.
