When Lily Potter was killed by the One-Who-Must-Not-Be-Named, she had just been home from the hospital after giving birth to her newborn daughter; Laura Lily Potter. That night, before Severus's arrival, someone else had been there: Mooney, James old friend. Remus took the girl in his arms and decided he couldn't leave her behind. He brought her with him to the muggle world, where they would now be living. When she turned five, Remus couldn't take care of her anymore, because he was too scared. The girl knew about his lycanthropy, but had never actually seen him transform. He was scared of hurting her. So, he sent her to a muggle family. It was a kind couple who already had a muggle-born wizard son, so they were happy to welcome her. When she turned eleven, she received a letter from the Hogwarts school, inviting her to study at the school. Dumbledore and Remus were the only ones to know about that girl being the daughter of James and Lily Potter. This is the Story of Laura Potter. (The first 3 or 4 chapters are shit, I wrote them a long time ago, but the rest are reasonable, so bare with me)
