Description:
For Day 3 of TwiPie Week on tumblr, prompt is "Newlyweds"!
A Beautiful Night by MrNumbers is one of my favorite fics ever. It's an AU wherein the Elements of Harmony didn't work and Nightmare Moon won. It's so good, especially the twipie in it.
SPOILERS: In the fic, Twi doesn't become an alicorn; she stays a unicorn all throughout even after saving the world.
