I really want evil Celestia. Since I saw Nightmare Moon. Sooooo you can guess how happy I was when I saw her using dark magic
There was this whole story I had in mind where, 1000 years ago (because that's where all the dark stuff is going down) Discord, after suggesting to Luna that ponies were sleeping through her night, and suggesting to Chrysalis to wait until a big wedding to take over Canterlot rather than just running in there to inevitable defeat, and also hinting to Sombre of a certain fragile kingdom, he goes to Celestia and informs her that she will never know how to protect Equestria (which at the time would of been a huge concern for her, I mean, evil would be coming from every direction) unless she took into account the magic that she was up against. So she studied into it, and then tried casting some of the magic, and although it helped her to defeat all of the chaos that was in Equestria at the time, the magic layed dormant in her mind, where it slowly began to consume her.
Tl;dr- Dark Celestia rocks. And even if you disagree I hope you get a laugh out of the faces they are both making out of context.
Ill make happier stuff later. Promise.
