The darkness of winter is upon Ponyville. Fluttershy, trying to escape the melancholy of her lone cottage, visits her friend Pinkie Pie. Pinkie is currently busy babysitting Pound and Pumpkin Cake, but does her best to cheer her up. However, she can't help but feel as if there is something dark and sinister stalking the small town. She excuses herself to make a visit to her friend Twilight, who does little to ease her concerns.
When she returns to the Cakes' home, she can't help but feel like there is something terribly, terribly wrong. The air is thick, and the feeling of foreboding unbearable. Little does she know that there is a spiritual storm threatening to consume Ponyville as the last foundations of sanity crumble into the torrential maelstrom.
