Twilight and her friends settle down in Ponyville after a crazy wedding crashed by a certain evil queen. On the way, Twilight realizes that she accidentally packed a mysterious device that isn't hers, something found after the ceremony ended. The large crystal ball has the oddest sort of rainbow-colored energy coursing deep inside and no sign of what it does. The six friends take a look. They tap on it, blow at it, and otherwise look for answers, finding no labels or anything else. Twilight accidentally opens it up, revealing a description written in some mysterious, alien-like language. She'll send it back to Celestia later, but for now she vows to find out more, deeply curious. She stays up studying to no avail.

Twilight wakes up to find her friends totally losing it, acting weirder than she's ever seen before. She decodes the ball, finding a cryptic message thanking Queen Chrysalis for buying the item. Noone knows how the Queen got this device, how to use it, why she brought it, how she lost it, and where the Queen herself is at the moment. Twilight must find a way to stop this insanity as well as get some answers.
