Premise:
All Celestia wanted was to be together with King Sombra, however Star Swirl-out of fear that it could bring great danger to both Equestira's-had closed the mirror portal and hid it away deep within the his personal library, never to be seen again. 1,000 years later however Twilight finds it when exploring The Castle of the Two Sisters. Exited at the possibility of exploring a new world, she quickly contacts Celestia, only to have the mirror confiscated, much to her dismay.

Many day later, Luna contacts Twilight and her friends revealing that her sister has been vanishing into the mirror at nightfall and has been slacking off in her duty's, as evidenced by her tired state when she does appear. Not only that, but at one point she came back clearly injured but passed it off as nothing, and recently she has been spending alot of time around Discord's statue and sending several units to attack the Changeling hives as part of a plan to "bring a new era of piece to Equestria", yet won't elaborate on what she means.

Later that night, Celestia is informed that the Crystal Empire has returned, prompting Celestia to "move forward with the final plan" and heads to the portal. At the same time the Mane Six and Spike follow her into the portal and end up discovering a whole new Equestria! But thing are much different from their home world...

What is Celestia planning? And how are the Empire, Discord, and the Changelings involved in it?
