Maybe Spike and the ponies with the Mane get transported to a parallel Equestria where the rules of magic are different. They have to figure out how to get back while also dealing with the strange new world. For example, in this world, Spike's fire - breathing ability might have a completely different effect or significance.
Well, obviously Spike is one of the main characters. He's a dragon with a close connection to the ponies. And then there are the ponies who possess the Mane. Although we don't have specific names given in just this title, we can assume they are ponies with unique personalities and abilities related to their Mane.

Well, perhaps in this fanfiction's alternate universe, the Mane 6 are all from different species.
