SkyJagged has just been hired as cloud distributor at Ponyville. Though the first two weeks were tough to get used to, it's more odd that he's met a pony who's even newer to the town than he is. But when yet another pegasus arrives asking about the first and talking about invasions and the destruction of the town, he becomes incredibly suspicious of both of their stories.

His search might just lead him to uncover a race long thought extinct… and capable of doing a lot of harm.

This story also fits under the category of "mystery", but that option isn't here.
NOTE: I couldn't find a picture that I felt suited the story without giving away too much, okay? Sue me!
