Nox Eternum

You are the Demon Princess. Everything was going so well for you. Your father, the Demon King, had established total rule over the entire land. Nothing was outside of the Demon Kingdom's grasp. Sure, your father was a bit of a tyrant, but you didn't let it bother you. You had everything, wealth, power, and most importantly: family. You were set up to be the successor to the throne of the Demon Kingdom. The world was at your fingertips. That all came crashing down though. The day when the "hero" showed up. You were only a child at the time, but you remember it clearly. You didn't think they day would ever come. The way he held your father's severed head like a trophy for the world to see. It made you scream, it made you cry, but most of all: it made your blood boil. But, unfortunately for you, it didn't end there. He wanted to make sure there was nothing left. Your mother, the Demon Queen, who gave you nothing but love and affection. And your siblings, your brothers and sisters with whom you laughed and cried with. They're all gone, slaughtered by his hand. The grand castle in which you grew up, was torched to the ground. You managed to escape the bloodbath, the last member of your family. Using the skills your late father taught you, you've lived a life of solitude among the masses of the outside world. Years have gone past, after the destruction of the Demon Kingdom. You've matured now, but you won't ever forget what happened that day. You didn't see their faces, but you remember a few things about them. The Wizard in White, the Cloaked Archer, and the Angelic Sorceress - members of the hero's party. And finally, the "hero" himself - the Knight in Shining Gold Armor. The world now lives in peace, thanks to them, but you don't care. Your entire family is dead because of them, and you're willing to plunge the world into chaos if that's what it takes to avenge them. The heroes all need to die. Take back what they took from you.
