Harry Potter struggled to reach over Hagrid to stir the flying Motorcycle towards the Burrow. Hedwig, his beautiful beloved owl, had flown to his rescue, giving him a few extra moments to get away at the cost of her own life. He prayed that while painful, Hedwig's death would be the only one. He gasped when he saw two Death Eater's chasing him and then frowned as the form of a wispy, stunning white-blonde female around Fred and George's age, appeared out of nowhere.

"Cover your ears Harry" she said and he did as she said, strangely trusting the unknown woman and also stunned that the bike kept going straight without his stirring it. He heard a faint female scream and saw the two Death Eaters fall off their brooms and fall out of the sky.

"Keep going" the stunning blonde female ordered and he looked at her and then nodded and drove as fast as he could towards the Burrow. He heard another faint scream and flinched as he landed. A while later everyone was back at the Burrow and Harry had been told by a pale Bill, that Mad-Eye Moody had been killed after Mongdungus vanished. Harry and everyone else in the room leapt to their feet, holding out their wands and Harry paused when he saw the stunning blonde that now looked fully human and not like a ghost as she had before. He then realized her hair was almost white, more so than Draco Malfoy's.

"Who are you?" Remus demanded and she blinked at him and her eyes began to water.

"Remus Lupin" she said and he looked at her, confused.

"Who is she?" Tonks, Remus' new wife, asked and the stunning white-blonde looked at her and then Remus.

"You would probably know me best as Rosaline" she replied softly and Remus froze.

"Rose?" he asked and she looked at him, with a calm look.

"It can't be" Remus shook his head.

"Why not? You can see me can't you?" the stunning white-blonde asked and he looked at her. Harry frowned as did Tonks at the look Remus was giving the unknown female.

"Remus who is she?" Tonks asked with a slightly jealous and possessive tone.

"Prove it" Remus demanded and she blinked at him and then nodded.

"Stag, Rat, werewolf and mutt, Prongs, Wormtail, Moony and Pafoot, added with Stripes. Sirius killed James and Lily" she said and Harry frowned at the toneless voice she used and Remus gasped at her.

"Sirius never killed my parents" Harry said and she turned and gaped at him.

"He was innocent, Rose. It was Pettigrew" Remus said and she looked at him. They all frowned when she turned on her heel and stormed out of the house. Harry and Remus shared a look and then ran after her.

"Stay back" they heard her say in a strained voice.

"Rosaline, what is going on?" Remus asked and she turned and they gasped. Her once stunningly blue irises now colored her entire eye leaving tiny black dilated spots, her hair was now blowing wildly in the barely existent wind and so did her strange, torn light grey dress.

"Rose…" Remus began and they both gasped as she flew into the sky and then let out the most agonized scream Harry had ever heard. They both watched as she finally floated back to the ground and then looked at him.

"Do you know who I am?" she asked and he shook his head and she looked at Remus.

"We…we...thought…" he began and she looked at him.

"We thought he had you. We never found a body so…"Remus whispered and she nodded.

"I understand" she said softly and Harry frowned.

"What is going on?" he demanded and Remus and the white-blonde, who was now, back to her stunning self, looked at him.

"My name is Rosaline…I'm…well…er…" she stuttered and Harry watched Remus walk over and place a hand on her which she quickly moved away from. Harry's frown only deepened when he saw an understanding look on Remus' face, despite her rebuff.

"I'm…your father's baby sister" she said and he gasped at her.

"You can't be. You don't look any older than 20" he said and she smiled softly.

"I am 32. I am just…different" she said and he frowned at her.

"What are you?" they heard Tonks demand as everyone else stood behind them, staring at the white-blonde.

"I'm different" she said and they looked at her.

"We're all different" Ginny replied and the blonde sighed.

"Not like me" she said and they looked at her as she turned to Remus.

"I'll be around" she said and then they all gasped as she took off into the sky and vanished.

"Remus who was that?" Harry demanded and Remus looked at him.

"Rosaline Hazel Potter, James' little sister. She graduated the year after us but she was in Slytherin" he said and Harry gasped.

"Slytherin?" he asked and Remus sighed.

"Rosaline is different Harry, just like she said. She…felt things so differently to everyone else" he said and Harry frowned.

"Remus, I love you, I really do but if you don't tell me everything you know about that…woman…I'll find out myself from Umbridge" Tonks threatened and he looked at her and sighed. He ushered them all back inside the house and they all sat, silently and patiently, well all apart from Harry and Tonks.

"Rosaline was different, she always was. She felt things so much deeper and harder than anyone else. See…Rosaline is or rather was… an Empath" he said and they all gasped.

"So what is she now?" Ron blurted and then flushed and Remus sighed.

"Hermione" he said and the smart female looked at him as he looked right at her.

"What happens to a witch with severe emotional pain if she's attacked by a creature that preys on people like her?" he asked and Hermione was quiet and then she paled and Ron grabbed her hand.

"No" she gasped and he sighed and nodded.

"What?" everyone else asked and the two sighed.

"Banshee" they both said and they all gasped.

"There's no such thing" Molly Weasley said and Remus shook his head.

"They are extremely rare, since many don't live for more than a year or two. They do exist but tend to live alone and never in just one place" Remus explained.

"Banshee's tend to be cold and unfeeling creature's, having lost most of their emotions during transformation" Hermione added and they all gaped.

"So…my aunt is a Banshee?" Harry asked and Remus nodded.

"How did she get that way though? I mean everyone has emotional pain sometimes" Ginny pointed out and Remus sighed.

"But it takes severe pain for a witch to be susceptible to the call of a banshee" Remus said and they all frowned.

"But what kind of pain…oh god" Hermione whispered and Remus nodded.

"Finding your brother and his wife dead would do it, added with the betrayal of finding their killer is a friend" Remus said in a voice just above a whisper.

"But I thought banshee's were meant to be ugly" George said and Remus and Hermione looked at each other and Remus smiled softly.

"Not always, depends on their looks before transformation. Last time I saw Rosaline was the day she came to Hogsmeade to meet me, Sirius, Lily and James. She was only 17, just about to graduate and she was just as stunning as she is now. When she was younger, she had the same long dark hair as James that always hung in pretty curls no matter what she did. Rosaline was always beautiful, still is even with her drastic change in appearance. No one knew of her transformation, we didn't know what happened to her. Everyone assumed that since she went missing, that she'd been the house with Lily, James and Harry and that you-know-who had taken her but it was never proved either way" Remus explained softly and Tonks stood and took his hand and he kissed it gently.

"I'm sorry, if I'd known I wouldn't have asked" she said and he sighed and smiled softly.

"No, Harry deserved to know why she hadn't taken him in" Remus said and Harry nodded.

"I understand Remus, honestly I do" he said and Remus sighed.

"She loved you Harry. From the second she saw you, she loved you. Spent most of her allowance on you, James always told her off for it. He accused her of spoiling you rotten" Remus chuckled and Harry smiled.

"Why didn't Petunia or Vernon say anything?" he asked and Remus sighed.

"Like I said Harry, no one knew what had happened to her. We all just…assumed the worst I suppose" Remus said and Harry nodded and then went upstairs with Hermione and Ron. Harry wasn't surprised when Hermione soon left to pick Remus' brain about Banshee's as a species.
