You used to have a family. You had a loving Father, mother, and a younger step sister named Amelia. But one day, when you were 16 and Amelia was 10, you lead a raid on your own village why? That's up to you to decide. Almost everyone in the village was slaughtered, but when you found the final survivor, poor little Amelia, you spared her. Why? Who knows. But now, 10 years later, you have become known as a powerful warlord named the Demon King. You're a powerful ruler, maybe a bit of a tyrant and a psychopath. One day, you hear rumors of a hero chosen by the gods to fight back against you. One description of her appearance confirmed everything you needed to know. This hero is Amelia, your younger step sister, now 20 and full of rage against you. She reaches your castle, fighting your guards and monsters, until she and her party finally reaches the very top of your castle, where you are waiting for her. How will you handle her? Will you give her a final fight that will be remembered for eons? Or will you corrupt her, make her an agent of your evil?
