Trixie is very bored. In an effort to relieve said boredom, she is reading her textbooks on magic.
This is a very bad idea.
The result? A spell goes wrong and Ponyville ends up with two Trixies, or at least two pieces of Trixie.
One is carefree, pompous, and just a wee bit more arrogant than usual about her powers.
The other is a nervous wreck that can't work up the courage to do anything based on the thought that it'll lead to a personal failure in her responsibilities.
They are two incomplete halves of a whole that have a spell to fix.
The problem with fixing it?
One of them decided to run off to Neigh Orleans during a night of endless partying.
A Lunaverse Story.
