I'm in this void. A mind separated from it's body and just thinking. I don't know what or who I am or even if I am. Do I exist? I must, but then why can't I remember anything...

Well I can remember one thing, it has something to do with shadows and crystals.

This story is a kind of what if story that takes place during the MLP FIM season 6 premiere. It's basically the idea that what if the Crystal Heart was preventing Sombra from returning, and when it was destroyed it let him return. Then the story takes place from his perspective in his own mind.
