A normal day. Twilight's doing research. Applejack's bucking trees. Pinkie Pie's doing who knows what. Rainbow Dash is practicing her tricks in Cloudsdale. Fluttershy is tending to her animals. And Rarity is making new clothes. But when they all are gathered by Twilight to see a huge ball of light floating down in the middle of town, who could his be? Is this the ancient and legendary Aero? Or is this a new enemy? Where is this colt from and why is he here?
