Nightmare Moon's return was cause for a lot a fear and panic. A lot of Chaos. Isn't it possible, nay probable, that all of that might have reached a certain draconequus statue? A certain draconequus that, once free, is a bit confused about what happened, and decides to investigate into who alicorn-napped Celestia and stole his shtick. When he realizes its Luna as what he dubs "The Eternal Prom Night Queen" (among other things) that's when things get interesting.

Watch how things unhold for the Mane 6, the Princesses, and all of Equestria when Discord not only gets free during Nightmare Moon's return, but also playing a major role in stopping her and saving the day. And seriously, what now, princess? Going to stone the hero while pardoning the villain?

This will be a Rewrite of the series. Don't worry though, Discord may seem nicer than he should be, but he is more curious than anything.
