Everypony has a dark side to them. Something they fear, something that could destroy them. As a certain purple unicorn is forced to use dark magic, she finds her fears threatening to consume her...Along with the darkness inside.

This story occurs directly after the end of season 3: episode 2. If you haven't seen it yet, go and watch it before reading this story. (This story is my take on where i think they're going to go with that dark magic we saw, it wasn't used nor explained nearly enough in that episode.)
