Young Celestia is trying to study for the night before heading to bed, however, her little sister Luna was always more active at night and quite a hoof full. With their parents away and Starswirl nowhere in sight, Celestia offers to show her sister a rare summoning spell book she 'borrowed' from the library.

However, Celestia misunderstands the purpose of the creature and after she summons Fetura, she quickly learns the familiar cannot be stopped, not until it has successfully bred a mare.
