Everything about the way this young drow woman walks and carries herself shows her adopted heritage.  Possesing none of the usual hautiness or confidence of typical drow women.  She carries herself almost meakly, seeming to not want to get in anyones way.  Growing up in a human settlement she was always looked down upon by those around her.  Keeping to herself most of the time and keeping to her studies.  Her adopted parents however raised her with love and so she understands it and embraces it when she can.  Being raised by humans has had an effect on her figure as well.  Eating the more human diet has given her a much more curvy body than the usual lithe figure of an elf.  Also her breasts are much bigger.  Having come of age she has decided to leave her adopted home behind and go out into the wide world in search of herself.  While she does know the stereotypes of drow society and peoples hatred of them.  She also knows how her parents came into being her parents.  So she knows the fate of her real parents.  So this about finding herself.  Becoming what she is meant to be.
