Many Equestrian philosophers, from the lowly Pluto all the way to the high and mighty River Muse, have written on the concept of ‘fate’. The script which the world must follow, the way things are supposed to progress, the way things are and always will be. Long have they, and many others, wondered what would happen if this fate were to change unexpectedly.

Twilight Sparkle, personal student of Princess Celestia, is on the verge of a breakthrough on Starswirl’s last and greatest unfinished spell, and is just about to finish the spell herself. But, before she can, Rainbow Dash goes off script. Fate is forcibly changed, and now the world as a whole must deal with the consequences.
And they’ll learn never to stray again.
