Ever Free, Ever After.

Princess Twilight Sparkle is greeted with a terrifying, new reality after expecting peace. When a darkened rainbow rift begins to form in the sky, she watches in horror as the surrounding ponies panic. The unfortunate ponies who couldn't help but stare in awe and fear had a bright, white light emanating from their eyes, nostrils, and jaws. Eventually, the poor ponies would soon be sucked into the rift, never to be seen again.. for now.

Twilight, believing that this rift is a black hole that marks the end of Equestria, tries to calm down her subjects, but realizes that there's nothing she can do. Feeling defeated, she watches every pony disappear in sadness, and remains frozen as the white light illuminates all that she can see. After some time passes, she feels herself getting sucked into a void of nothingness- or, rather, a new realm?

Twilight finds herself back at her castle, however, she notices that things are drastically different. The environment looks the same, the designs of the buildings also look the same... but the ponies that she once knew and recognized were dressed as... fairy-tale characters? To her surprise, they have no memory of who she is, either.

Twilight learns that there is a balance of goodness and evil within this world, and if she truly wants to save all of Equestria AGAIN, she must help each and every pony reach a good OR Paccurate fairy-tale ending. Will she have the will power to do so? Will everypony ever remember who she was? Or will she remain forgotten, her life meaning nothing to them?

Only time will tell.
