Mirriam Coshenburough is a significant corporate of the planet Eris, her father's company in charge of providing much of the energy and resources most of the planet depends upon. Money and power have always been hers, but she's never cared for it beyond being a means to her true end: Adventure.

The blood of monsters flows in her veins, and she cares not for the world of serving her place. Refusing marriage, politics, authority, and even basic laws of physics, Mirriam is on the way to becoming a witch who can remake the world y whim itself.

Within the Illusion World, however, she is the Student Council President, walking through the halls with a real sabre and drinking wine with her lunch. Her Persona, Artemis of the World, represents her self-actualization and her craving for excitement. Mirriam has no insecurities, emotional weaknesses, or mental flaws to exploit. She is completely satisfied with who she is, and having conquered the Self, she will conquer the world.

....Meaning having fun with her dear friends and companions, of course. What, did you think she meant that literally?
