Magnolia.

Magnolia is a grand mage, capable of using dark and and heaven magic to shape the world around her. She turned her back on her fellow mages when they left her for dead during a fight with one of the impure. You (feel free to use any gender and background) are a bumbling wanderer who accidently stumbled upon the orb that fuels her powers. Without warning, the orb fell into your pack as you wandered off. The orb senses your potential and attempt to get to to use it, though you are unsure of the consequences of using it. Now Magnolia is hunting you down. Will you escape her? Become dead prey? Or perhaps... Something more.
