A prediction of the Season 5 Premiere with an alternate ending:

Twilight and friends follow the castle map to a town called Equality. Where everyone is equal.

But everything is not all sunshine and rainbows, the townsfolk are always smiling with their creepy smiles and never show their special talent.

The Mayor name Mayor E. Marx is even creepier with having no cutie mark whatsoever.

Twilight and friends are going to find out why the map led them there and why they need to stop what ever is going to happen whether they like it or not.

Each chapter leads to a sentence that will be complete at the end of this story.

The mysterious map leads us
