Solidly built, strong shoulders and broad chested, Mir is hardly the image of delicate feminine beauty. She does not let this stop her from carrying herself with a lightness and grace that her massive body, according to stereotypes, should not have.
Though she does not suffer any signs of illness yet, due to her young age, as she grows, she will find herself suffering joint pain and random aches. This will only spur her desire to research more into the medicine that she is certain will give her immortality-- if not true immortality, then immortality in word.
Mir is, first and foremost, an arrogant spirit. She believes truly and earnestly in her mind. She is clever, at least, perhaps not the genius she claims to be, and she learns well. If she were slightly less of a tool, she might have considered a regular career as a simple healer. Mir, however, is drawn to the grandiose. It is not enough to simply be smart. She wants to be worshiped. She wants to be admired. She wants to become God Itself, if she can. Rejecting the spirituality of her aunts, she has settled for Divinity Through Science. If there are gods out there, let them prove themselves greater than her own intellect.
