Reports of strange, almost sentient storms have been trickling into Canterlot from all over Equestria during the past month, and Princess Celestia has noticed an uncanny similarity between each of these reports. Every time one of these storms appears, it is clear that these storms are hunting for something.

Despite the obvious connections between each of these occurrences, it is unclear as to what it is that the storms in question are searching for. Unclear, that is, until tragedy befalls one of the Elements of Harmony. The remaining five ponies must hurry to uncover the answers to some very fundamental questions, all the while fighting to protect the remaining Elements.

However, in order to do so, they will have to dig down to the age-old fundamentals of good and evil, learning things about themselves that might have been better off left unlearned...

-Not every cloud has a silver lining, but everything good has something evil to go along with it.-
