You've accepted the responsibility of protecting the moors from those who seek to destroy it and all of the creatures who live there. Part of being their protector is being prepared to stoically stand guard ready to use whatever means you can, including magic, to keep the moors safe from harm. Holding your Maleficent staff at your side, you will be able to challenge anyone who tries to defeat the defenses you've put into place.
Have a little pent up anger over losing your wings to the scheming King Stefan? It's nothing a little curse can't help. Crash the christening of his first born and show him what it means to lose something precious beyond measure. You might come to regret it years later when you realize that you are completely in love with that little girl, but for now it sure will feel great to let your wrath be felt!
Your closest friend and ally, Diaval, will help you stay one step ahead of King Stefan and his army. So it's important to acquaint yourself with a talent for talking to ravens. He will listen, advise and protect you as no one else can. Plus, when you walk around with a raven as your companion people tend to be intimidated by that and as Maleficent this is exactly what you want.
