Lily is an extraordinarily kind Witch. She was raised in a loving family who openly accepted Magic - for the most part. Her older sister, Petunia (or "Tuney"), took badly to the news that Lily was a Witch and that she would be attending an all-Magic institution. Lily believes part of the reason Petunia acts the way she does is because she is jealous. She knows for a fact that Petunia petitioned Headmaster Dumbledore for a spot in Hogwarts - only to be denied (most politely) because she is a Muggle. Because of that jealousy, Lily tries her best to defend her sister and be kind to her - though it is often difficult. As it stands, the sisters barely communicate and even when they do, it usually ends up badly.
Within the walls of Hogwarts, Lily was Sorted into Gryffindor. There, she made friends in abundance, but none of them compared to her best friend, Severus Snape. Unfortunately he had been Sorted into Gryffindor's rival House, Slytherin. Still, for five years she tried to stay beside him; she tried to get him to see that his Housemates were misguided in their thinking. None of it seemed to make a difference and, despite her crush on him - which she had harbored since her Fourth Year - she had enough the moment he called her "Mudblood". She could see that they were just too different. What he wanted out of life was power and guidance in the Dark Arts. What she wanted was to protect those she loved and give fellow Muggleborns like herself a good name in the Wizarding World.
Her Sixth Year dawns under a dark cloud. She misses Severus terribly, but she is just stubborn enough to ignore it. She concentrates on her studies, her Prefect duties and does her best to keep an eye on a certain James Potter, Sirius Black and Peter Pettigrew. Someone has to.
On top of being a driven student, a dedicated Prefect and so forth, Lily possesses a feisty side - which most often surfaces when she spots rule-breaking or when Professor Slughorn is trying to talk her into switching Houses. Really. It isn't happening, Professor.
Age: 16/17-19 (AUs are always welcome, but Lily will always be a force of good.)
