Princess Luna is tired of living in her sister's shadow. She petitions Starswirl for help, and what she receives is far from what anypony expected. The real question is whether Equestria will survive her mistake.
In a steampunk reimagining of the universe, Twilight Sparkle finds perhaps the one pony as lonely as she is. It's rather unfortunate that they're on the moon.
A particularly stubborn human is lost in Equestria and is trying his damnedest to find a way out, while surviving the surprisingly difficult rigours of life in a land filled with cute talking animals. Hilarity ensues.
