Lyra becomes madly twisted by science and Nietzsche's philosophies! Her rampage upsets small business in Ponyville! It's up to Alicorn AJ to save the day!
This is a (nonsense) side story to The Assumption of Applejack -or- Appletheosis. It's set five years after the events of that story. In an alternate reality. In a dream. Induced by fever. Or something. Whatever it is, it isn't canon. I apologize in advance. Partially inspired by the cover image.
[Edit:] There is now a sequel: Apples and Lyras by Rokas. Check it out. I totally endorse it as an alternate canon ending to my excessively apocryphal fic.
