Original story idea was Alphamon_Ouryuken's.

Long ago in the magical land of Equestria, the righteous King Sombra ruled the Crystal Empire in peace, but there was a time when three others also ruled along side him. Chrysalis, his beloved - who went into hiding because of a curse placed on her - along with Celestia and Luna - who sadly became drunk on their own power, and he was forced to banish.

A thousand years later, his prized student Sunset Shimmer is given the task of make sure the Crystal Faire goes as it should, as well become more social with the citizens, but sadly that task is derailed by the disappearance of the Crystal Heart, and the return of Daybreaker and Nightmare Moon!

Now Sunset must find a way to stop the two tyrannical Queens before they bring the Empire to ruin! But she might need a little help . . . from the most unexpected sources . . .
