For centuries, ponykind thought Princess Platinum's splendorous silver crown lost for all time, but it has been found. Twilight Sparkle, the self-proclaimed Princess of Thieves, has tracked it down to the long-fallen Diamond Dog kingdom of Erebark, and means to enter the mountain to retrieve her kin's lost heirloom and settle scores with Princess Celestia.

Unfortunately, there are one or two details she didn't realize going into this mess. Namely, that she'll need to steal from the gilded gallery of one of the mightiest dragons ever to walk the land.

Oops.

Tragedy strikes the Sparkle estate one winter evening and Twilight finds herself cold, alone, and far from home.

Fortunately she stumbles across two fillies who may have more in common with her than she realizes. With no place else to go, nopony else to turn to, and no clear way back home, Twilight decides to stay with the fillies and their caretaker while she tries to piece together the mysteries of what happened to her family and why.

Bonds will be forged.

Secrets will be unraveled.

And a great journey will be undertaken.

A time travelling Spike is inviting all Twilight's closest friends to her one thousandth birthday.

Wait isn't time travel extremely dangerous?
Don't worry. This is a predestination paradox. Nothing you do will change the past.
Oh, so everything is going to turn out okay right?
Right?
