Everyone knows of Twilight Sparkle, personal student to the princess of the sun, and element of magic. She has friends, family, and above all, hope.
However, Twilight Sparkle doesn't exist. In fact, Equestria doesn't exist either. All it is and will ever be is a figment of my imagination. Simply a way to live out the rest of my days with a slight measure of happiness. I am not her, but I would give my horn to be her for but a single day. To have everything, and yet not realise how lucky you are to have such things, to live.
What I am doing right now is not living, this is waiting for death.
Everyone gives into hopelessness eventually. When you're the only pony left in the world, and your name isn't actually Twilight Sparkle, what is there to hope for?
The world is doomed, unless the chosen one dies. The chosen one of the purple body and neatly cut mane.
