Twilight Sparkle succeeds in finishing Starswirl's mysterious spell, but just as her friends have rediscovered their true callings Celestia informs her of a new great purpose. Twilight and the other Element Bearers are to travel far beyond Equestria's borders, perform a spell together, and once again seal away an ancient evil that threatens not only Equestria, but all of Equis. Of course Twilight and her friends have vanquished many a foe in the past, so this seems simple enough.

But it's not. Celestia isn't telling the entire story. There is more to Starswirl's spell - and Twilight's destiny - than the six bearers have been told.

Thrust deep into an unknown world with little direction, Twilight and her friends will soon find that there's more to Celestia and Luna's shared past than they could have ever thought possible... and that the Equestria they call home may already be far beyond saving.

Just how, exactly, was Equestria really made?

An alternate universe diverging at the very end of "Magical Mystery Cure". Ignores comic canon. An attempt was made to stick to canon geography, but considering the world hasn't been mapped out in full there will be headcanon thrown in as well.
