When Twilight is sucked into the illusion of the dark magic door in the Crystal Palace for a few seconds longer than canon, it leaves a lasting effect on her. The ripple effects of this causes her to seek out dangerous magic and put an end to anything that could be abused by the wrong hooves, not realising she herself is falling to the effects of dark magic.

Actually pretty decent as far as Twilight falling to darkness fics go, I'd love to see you revisit this with a longer version that is more fleshed out after you are done with your month of madness.

But what if it is Celestia who has fallen to the allure of dark magic?
I agree with the points you brought up. Alas, to see this one-shot turned into a longer story would please a great many people.
It may have fallen short of what you wanted , but it’s not bad. I liked you writing Twilight for a change. You have her voice down. I agree with you that a little more could have helped that, ”and suddenly crazy” effect.
So how will this affect the timeline? Y'know since Twilight is now a statue, What will happen with Tyrak or the storm king invasion? Or any other threats that will happen after this? Also another bearer for the element of magic? That would probably take thousands of years if not ever!?
