When Luna was only but a filly, she began to hear voices in her head. They were whispering vile and wicked things into her ears, telling her that she will do unforgiving acts of pure envy to one Princess in particular. But, Luna didn't have much of an idea if the voices were there to help her, or hurt her, because of her young age. It didn't help that the voices were altering her thoughts with trickery. This is the story of a corrupt mare, who almost plummeted Equestria into eternal night.
