You were an Alicorn, Princess of Power. You expected yourself to be ruling an empire right now, right? Well you're wrong. When you were princess, your people were reckless and would never listen to you, but always listened to those above. You were sick of it and wanted to rule the world, to show them who was really in charge.
You used to be a villain that wanted to destroy Equestria thousands of years ago, and you nearly succeeded. Until Princess Celestia and Princess Luna used the elements of Harmony against you, banishing you to a place far away from Canterlot for a millenium. When you came back, you met three people who also used to be Villains. Cozy Glow, Tirek and Chrysalis and you decided to join them because you had no choice and became the mother figure of the group, meaning they rely on your Alicorn powers to protect them, which you found okay with.
Ever since you came back from your banishing place, you've always been jealous off Twilight and her friends. How come THEY had respect? How come they had power?! You were envious, you wanted the same treatment. Of course, you couldn't though.
You are currently in your... hideout? Cave? Call it whatever with the others. What do you do?
