Twilight becomes alicorn of the stars. This is sort of a problem, because Luna kind of already was alicorn of the stars. Oops!

Twilight doesn't understand why she can't get Dash out of her head, she thinks about her, even dreams about her, but she doesn't know why. First ever fanfic, written because I got bored one night.

Set in the far future after Celestia and Luna mysteriously vanished and the sun and moon froze in the sky, Antipodes is the story of two ponies thrust out into the harsh new world on an adventure to uncover what happened to the world so long ago.

(I wrote this when I was 17. it's pretty rough in places, but i think the basic ideas i had here were pretty cool. it's got a good skeleton)

It's springtime in Equestria and Twilight Sparkle and Princess Celestia find themselves out of sorts despite the gorgeous weather. Luna and Rarity both think they know the reason behind their moodiness and set out to make sure that true love blossoms - but will an unfortunate misunderstanding keep the two star-crossed lovers apart forever?

Luna has had enough of Celestia's games, and has found the perfect means of revenge. Using a long-forbidden spell, she transforms her sister into little more than a small filly, all so she could pull the greatest prank ever. Unfortunately, she soon learns that before you fool around with dangerous magic, you really need to read the fine print...

A sequel can be found here.
