This story is a sequel to Music, Muscle, and the Multiverse

Discord has been ruling Equestria for 30 years. The heroes that returned found themselves hopelessly outnumbered, and the "King of Chaos" assimilated them into his vast army.
Treble and company find themselves in a new, damaged world, and must try to return it to the way it once was, while battling Lord Discord's evil army.

I really shouldn't have to make this disclaimer: Please don't dislike the story based on premise. It seems like at least seven to eight of the dislikes it has are because of people who didn't actually read the story. As such, I would like to put forth a request to read before making a judgement. If you still don't like it, then, by all means, dislike.
Set in a parallel universe to 5s4 Equestria, as written by TwistedSpectrum. Only a small amount knowledge of the original five score universe is necessary.

First true story in the Trebleverse system
