This story is a sequel to Futility

After traversing a barren landscape, and apparently surviving a fatal spell, I have arrived in a literal heaven. But, Futility is always around me, even now. We are a doomed planet, unless we sacrifice her.
It seems fate has a sick sense of humor. But mark my words:

At the end of this battle, there will be at least one mare with a purple body and a neatly cut mane lying in the dirt dead.

And it won’t be me.

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.
