A crossover with the movie The 5th Element.
Every 5000 years the stars will aid in its escape: The supreme Darkness and ultimate Evil. There is only one thing that can stop it. The 5 Elements of harmony gathered around a 6th, the supreme warrior, the perfect pony. It's up to Rainbow Dash and the 6th Element, with the help of a determined priestess and annoying DJ, to complete the weapon and stop the Darkness in a race against time.

This was my work during National Pony Writing Month. While I knew I wouldn't have time to do the 50k, I focused instead on quality. Enjoy.
