The black phoenix

Maybe you know any stories about fairies, mermaids or vampires. But there are also witches. Most the witches just play a little role in the stories, but they could be the most powerful creatures of all of them. They could fly like fairies, swim under water like mermaids or could be as strong as vampires, if they would use their power for themselves. But they didn't because they were loyal companions and did their job pretty good. We were always thought to become friends with them, but then there was me... I wanted to use the power for me and not for anybody else. I know every story has a good end and this story does too but I think I'm the only one who thinks like that and nobody could change my mind...
