The phoenix girl (MCSM) (Being rewritten)

Everyone knows to never mess with Petra. She is very easy to anger. Especially when someone picks on her friends. Some say that when she gets angered enough, her amathist eyes glowed gold. However, she has a reason for her anger. Something no one ever knew. Not even Jesse. The only thing left to do, was to prove that the admin can be defeated with her power. She knows its the only way. Why? Because this is her destiny. But the question is, can she fight back against all that stand in her way, or will her life shatter into pieces of darkness, forever?
Warning, Jesstra alert. If you don't like Jesstra or lesbian ships then get out now.
