Ponyville; a town that is plastic and fake.

It's the home of Dusty, an adopted Pegasus who soon learns about Real Trees; and how they were once all over Equestria. So to know what happened to them, he talks to Applejack; a pony who is the only one who knows what happened to all the trees.

She tells about her early years; before Ponyville even existed. She tells about the mysterious Zap Apple Trees, and the magical fruit they created. And she tells about the one pony who spoke for them.
