Nightmare Moon is a powerful mare. She is a very powerful, very crafty mare, with more intelligence and wisdom in her left hoof than most other ancient beings have in their whole bodies. So why was she so easily defeated? The answer- she wasn't. Her sister may have overpowered her with the Elements, but she was close in power levels to begin with. What could six little ponies do? The answer- Nothing.

Twenty years after that crushing defeat, Twilight wakes up from her slumber to find a Diamond Dog trying to free her from her imprisonment. In the following days, she learns what has happened in her absence, and uses what little knowledge she actually acquired over her twenty year imprisonment to make the monumental task of defeating Nightmare Moon ever so slightly easier.

Thankfully, she has access to all her 'old' friends, as well as a few old 'villains' to make the journey at least bearable. Her new 'niece's' crazy inventions are sure to make things easier in the long run, if those holes in the wall are any indication.

If only her brother weren't such a douche.
