Desteria

You are a you girl living in a village by kids for kids. You never met or have any knowledge on your parents. Your village is hidden within a enchanted forest. The kids must leave once they become adults. To your surprise you don't age the same as other children being still a young child. One day an old wizard with a long white beard came to your village and was captured thinking he was a kidnapper. The moment he first laid eyes he freed himself with his magic scaring all the children. Walking up to you he pointed and said, "You're the one who I have been searching for all these years." He told you had great magic within you, evil and destructive magic that will one day destroy the entire world. You were confused because you don't know magic and scared that he was going to kill you. However, he said if you die in any other way than a natural death the evil magic will be released onto the world. He doesn’t know how to get rid of it, but is trying very hard to save and to find a cure. He gave you a blue gemstone brooch to help control the evil magic that escapes when you're upset making it turn red. On your journey there are numerous people who want to kill to prevent the destruction of the world. You don't understand why the wizard had heard of you and why he's so nice to you since you could destroy the world. You wonder what's the connection between the two of you.
