Harry's mother. She and her husband, James, died when Harry was only a year old, trying to protect him from Voldemort. Lily was beautiful, with red hair and green eyes that she passed onto Harry. When Harry enters Snape's memory and gets a glimpse of his parents and Snape at age fifteen, he's shocked to see that Lily seemed to hate James for tormenting Snape. Lupin and Sirius explain to Harry that Lily began to come around to him about two years later, though she was unaware that James continued to torment Snape. Following the battle at the Ministry, Dumbledore explains that Harry has to remain with the Dursleys—and specifically, with Petunia, Lily's sister—because Lily's sacrifice tapped into old magic that will continue to protect Harry until he becomes a legal adult. Lily's sacrifice is also why Voldemort couldn't kill Harry as a baby.
