Twilight Sparkle, Applejack, Rarity and Spike are on their way to a distant city, but lose their way. When a thunderstorm breaks loose, they seek refuge in a nearby manor, where time apparently stood still. Not everything is as it seems, as all around them, spirits rest uneasily and the supernatural manifests around every corner.

Rainbow Dash's life long dream finally becomes reality. But when she finds out at what cost, is it still worth it?
