Spoilers for the general plot and ending of the G5 movie.

The return of magic also caused the Crystal Empire to appear again, but two Crystal Ponies, banished from their homeland, wish to change that.
And now it's up to Sprout to stop them, save all of Equestria's magic, and accept that his family played a larger part in history than he would have enjoyed.

Written for the G5 Bingo Writing Contest. Prompts were "Sprout + is keeping a secret from + Sweets + Crystal Ponies + School for Gifted Unicorns".
Contains a silly plot, (intentionally) butchered history, and stereotypical Swedish/IKEA-ish proper names, mostly meaning that I added a bunch of unnecessary umlauts to vowels. =P I apologize to Prince Shining Armor, Princess Luna, and all Swedish people reading this. Also contains an actual IKEA name - Älvängen/Alvangen is/was a set of lamps, including a desk lamp.
Might do something else for the cover image later - right now it's nearly 1am and the deadline is upon me, so this needs to go out NOW.
