> In this AU, Celestia and Sunset have swapped roles.
>
> After stealing Starlight's crown and escaping back to the human world, Celestia planned to use all that newfound power and return to Equestria, ruling it as she saw fit. However, she didn't realize that magic worked differently in the human world and when she put the crown on, it transformed her into a monster.
>
> In this form, Celestia's insanity was cranked up to 1000. She didn't just want to take Equestria, she also wanted to make Starlight and her friends suffer for trying to stop her. She was going to take all of the sun's energy and leave the human world, along with Starlight, in complete darkness before going to Equestria.
>
> Thankfully, Starlight and the elements of harmony had managed to free her from the dark magic and bring her back to her senses. Once defeated, Celestia was overcome with guilt and shame at what she had done. The mane 6 accepted her apololgy and decided that they would help Celestia learn what friendship truly was.
