The mansion was dark on the outside, framed by the glowing white of the moon. The air was warm, but cool, which was typical of the summer months. But for Harry Potter, as he stood outside the mansion, he was sweating nervously as he stared at the ominous wrought iron gates. Malfoy Manor was one of those grand places that he had come to associate with the wizarding world; it was also typical of the Malfoy family image, really, with its grandeur, and he had no doubt the place was highly protected.

Tonight was his seventeenth birthday, and if tonight went the way he hoped, then he would never have to fear anything from Voldemort ever again. The Order's intelligence on Voldemort's location was limited, and he had only gotten it after placing one of the elder Weasleys under the Imperius curse and then wiping their memory, but the intelligence was very old but it was all he had to go on.

Harry walked up to the gates, screwing up his courage as he did. As he studied the gates, he saw there was no way he could open them.

But he didn't need to.

"State the intentions of your visit," a grating voice that reminded him of the Daleks he and she had watched as kids on the rare occasions Mrs Figg allowed him and Rose to watch TV (don't think about her, not yet; with a bit of luck he would see her soon).

Taking a deep breath to steady his nerves, Harry spoke aloud, "My name is Harry Potter. I wish to speak to Lord Voldemort. I have a proposition for him."

The voice didn't speak again, and there was no sound for what seemed like an eternity. But as he checked his watch while he waited, he was only waiting for half an hour. He paced up and down, glancing at the Manor. He wondered what was going on in there. He knew now the Death Eaters were aware of his presence that they were stunned by his arrival and what he wanted, and they were likely making decisions about what they should do.

Harry merely hoped Rose and Voldemort kept things calm, and that Rose would point out that he wouldn't be here unless there was a good reason.

There was no sound.

It was as if the world had gone still as it listened to his proclamation.

Finally, the gates opened and Harry held his head high as he marched down the winding gravel path. With each step, the manor grew larger and larger until it was looming over him, and two Death Eaters were standing outside by a door at the top of a small stone stairway lit by a magical lantern charmed to light at a specific time.

Harry stopped by the base, wondering what was going to happen next. The light reflected off the white face mask eerily, but he couldn't see the eyes. He had no idea who was in front of him, never mind what they were thinking.

"Come in, Potter," one of the Death Eaters said. Harry recognised the voice of Bellatrix Lestrange. She sounded…surprised, stunned, and nothing like her usual insane manner. He had always likened her to a Berserker from Viking culture; she was only mad whenever she went out on a raid, but she was quite sane underneath. This just proved it.

Bellatrix walked into the manor, gesturing he should follow and Harry followed her while the second Death Eater followed on behind. The door slammed shut. Harry followed the Death Eater, seeing for himself that Bellatrix was genuinely puzzled and she kept looking over her shoulder, glancing at him curiously. Harry wondered why she didn't say something, but guessed she had been ordered not to, although why Voldemort would do that, he didn't know. Bellatrix led him down corridors lined with portraits, who stared at him judgementally. He ignored them.

Finally, they came to two double doors painted black and gleaming with the crest of the Malfoy family on the handles. Bellatrix pushed them open and they went inside before gesturing for Harry to go in first.

"Thank you," Harry said politely to her as he walked past, hearing a sound like a scoff behind him. But he ignored that.

The room was dominated by a large wooden table made from dark wood with matching dark chairs. Lining the walls were black-clad figures, some of them wearing ordinary wizarding robes, although a few wore Death Eater garb sans the hoods and masks. Clearly, they were ordered to meet as they truly were. Harry recognised Lucius Malfoy and the Lestrange brothers instantly.

But then he saw Rose.

She was standing close to Draco Malfoy, her beautiful face, inherited from her mother - their mother - was slack with shock and surprise. The question was obvious in her gaze.

'Why are you here?'

Harry spared her a small smile.

Rose was his twin sister. She had gone into Slytherin whereas he had gone into Ravenclaw because of his intellect although it had been a close tie between Slytherin and Ravenclaw at his sorting. Unlike many others at Hogwarts who saw the Slytherins as evil, Harry knew his sister wasn't; like himself, she was ambitious and resourceful, but whereas he was more geared toward intellect, she was more geared towards ambition, and for three years they shared and enjoyed a warm relationship.

And then it became tense.

During the Triwizard Tournament, Rose's boyfriend, Cedric Diggory made the mistake of suggesting they both take the trophy, but when Harry, who knew the whole thing was a trap geared for him, Cedric had come along and was killed. Rose was distraught, and she had spoken to Dumbledore and the old fool had told her Harry's blood was used to bring back Voldemort while Cedric was collateral damage in the whole thing, and he had seen their parents. Harry and Rose's views on their parents were mixed; while they loved Lily and James, they had never known them, and they had always been in pain over them and the contradictions they'd been given about their parents over the years. But they were still their parents and the twins missed them. For Harry to see them, and not Rose was deeply painful.

She had gone off with Draco, who was one of her friends in Slytherin House. Harry had never found out what had happened to her over the holiday, as she refused to get in touch despite the numerous letters he'd sent her. But in their fifth year, Harry had gotten the message from his glacial sister. She didn't want to speak to him. And he didn't know what Voldemort had promised her, but since both twins were more neutral towards the Dark Lord than people like Sirius and Dumbledore would have wanted, Harry had some ideas of what Voldemort promised her. He doubted it would be an offer for their parents or Cedric, Rose was more realistic than that. It was more likely she wanted revenge against the muggles, especially those who'd tormented and abused her, them, as children.

Anyway, she was a Death Eater now, he had seen her Dark Mark burned into her arm as she and Malfoy killed Dumbledore. Unlike the Weasleys or even Sirius, or one of those narrow-minded Gryffindorks, Harry was more hurt she hadn't told him that instead of being dismissive towards her now.

Harry turned away, ignoring the other Death Eaters, seeing they were gazing at him in surprise and disdain.

Sitting at the head of the table was Lord Voldemort himself. The Dark Lord was gazing at him with his usual cool manner, his red eyes flashing without any curiosity as he watched the lone dark-haired boy wearing a long dark cloak striding towards him.

Finally, Harry stropped close to Voldemort, gazing at him. He and Voldemort locked eyes, with his gentle breathing the only sound he could hear, while he tried to keep his nerves.

Voldemort broke the silence first. "Harry Potter," he spoke in his usual, low, measured tones. "Why have you come here to me, and what is the proposition for me?"

This was it. No turning back now.

Harry took a deep breath and he knelt on the cold floor. "I wish to join you, My Lord," he said to the surprise of the Death Eaters while he tried to keep calm, "You are going to win. I want to be not just by your side, but my sister's as well when you do."

The Death Eaters were stunned into silence by the Boy Who Lived's words, to say nothing of the casual way he had just thrown aside any light allegiance. All of them glanced at their Lord, wondering what he was going to do next and were preparing to follow his lead. All but one. Rose was gazing at her brother, surprised by his brazen approach which was nothing like him.

Harry meanwhile was more worried about what Voldemort was going to do, next mind what he was going to say. He had no idea how the Dark Lord was going to react, but he hadn't killed him yet, so that was something.

Voldemort stunned the audience when he began laughing. "Ah, Harry, I was always hoping that you would see this fighting was pointless. I had even hoped when you saw your sister had no malice towards me nor do I have any towards her, when she became a Death Eater, and a member of the Inner Circle that you would see I had nothing personal against you. I have nothing but respect for you; a young, powerful Ravenclaw, extremely creative in magic…but first I need to make sure this isn't a scheme from Dumbledore. Stand up and come towards me, Harry."

"Thank you, My Lord. It was partly why my sister is here that I came. I don't care about the Light, never have. All I cared about was my sister; if you look back over our previous encounters, you'll find I only defended myself, rarely did I attack back," Harry stood up and Voldemort likewise rose to his feet and stepped closer to Harry. As the Dark Lord rose, Harry spotted the expression of disbelief and surprise on the Death Eater's faces.

"Yes, I remember," Voldemort nodded as he thought about what he'd just learnt. "Look me in the eyes," Voldemort ordered.

Harry obeyed his first order as a Death Eater. He gasped as he felt Voldemort go into his mind. He had tried to learn basic occlumency at school, but whatever was in his scar had made it impossible, so he had done his best to avoid thinking about things when he was in Dumbledore's presence, and since occlumency relied on wrapping his magic around his mind despite several hurdles, he found it easy to let Voldemort inside.

Thanks to his meagre experience in the mind arts, Harry saw images of his childhood fast forward. He saw the abuse and the humiliation he and Rose had endured; him seeking solace in books and creativity while he and his sister both thought up brilliant ways of escaping Dudley's gang; their hatred for the Dursleys and the residents at Privet drive; their meeting with Hagrid who kept brainwashing them into seeing Gryffindor as perfect without realising the twins had their own views; their sorting where Harry was a potential Slytherin but his intellectual interests had won out; Voldemort paused when he came across moments where Harry and Rose spoke about their disgust towards muggles, seeing them as nothing more than animals and Harry's discovery of the Rappaport laws in the MACUSA which spoke of a world where magic was truly separate, with muggle-born children removed from their families in order to furnish the MACUSA with fresh, new blood without any links to the muggles whatsoever; Voldemort stopped when he found moments where he was kind towards muggle-borns but disdainful towards their muggle relatives; Voldemort paused when he came across Harry's interests and what he liked to read, and how he and Rose practiced and laughed together and had fun before the last two years; Dumbledore and the Order roping him in the war when he wanted nothing to do with it since he just wanted to be left alone and he truly didn't want to fight for muggles as it insulted his pride as a wizard; Dumbledore falling to his death (Harry felt the Dark Lord's shock when he saw Harry forcing that poison down Dumbledore's throat without any kind of mercy) and the Order just breaking ties with him before he had made his mind up, to seek Voldemort and join as a Death Eater, so he could take his revenge on the muggles.

He already had several ideas in mind to help the Death Eater's cause; he had originally intended to do it alone, but like this in this manner, there was a stronger chance, and with Dumbledore dead, there wouldn't be anyone to oppose him. And, after learning of the Potter family history, where he had learnt several of his family had joined Grindelwald after finding his visions of a wizard-ruled world compelling and then later when James Potter's sisters, Cleo and Natalie had joined the Death Eaters, Harry had wanted to put things right.

Time had no meaning when Voldemort went through his mind more gently and subtly than he had expected, but when Voldemort was finished the Dark wizard just retreated, leaving Harry to stagger and lean against the table, wincing with the effort. He was surprised when he felt Voldemort's spider-like hands on his arms, steadying him and helping him straighten up.

"Relax, Harry," Voldemort said. "I didn't intend for it to be severe."

Harry nodded but he was too breathless to reply.

"This young man who has proven himself to be an extremely powerful and capable wizard is loyal to our cause," Voldemort announced at large, "he was never loyal to Dumbledore, as we were led to believe. Now, he will become one of us. But first, the world must see that he is not one of them, but one of us. Harry, hold out your arm."

Harry raised his left arm. Voldemort took it and held it in his grasp gently. Stroking the skin with the tip, muttering an incantation. Harry winced as his arm started to heat up, but he held back the urge to shout or scream when he felt magic pulsing through his arm, radiating from the wand tip. It felt like he was being branded by a red-hot iron, and in a way he was. But he refused to scream. He would not be weak-

Finally, the Dark Mark began to appear on his arm, spreading outwards. Shaped like a skull with a tongue protruding like a ghastly tongue, wrapping itself around the skull, painted in tones of black, red and green. Voldemort let go of his arm, and Harry gently ran his fingers over it to make sure it was there.

"Welcome to the Dark Order," Voldemort said, "Now you are officially one of us, a Death Eater. We are one family. United under the Dark Mark. The Mark will link you to the others, letting them know you are one of us. When you are summoned, the Dark Mark will let you instinctively know where the meeting is."

Harry looked down at the Mark and then back at Voldemort, the leftover pain from the initiation fading. Harry had always hated the weakness of the Order of the Phoenix, led by Dumbledore, who refused to do anything constructive and he had always resented them for not seeing that muggles were the enemy, not their fellow wizards and witches.

In any case, the Order and so many people lied about the Death Eaters.

Voldemort wasn't trying to kill muggle-borns.

He was trying to save them.

He remembered how he had been treated by muggles, and he wanted to ensure nothing like it happened ever, ever again. Unfortunately, Light propaganda worked against him. And he and his followers were called monsters. It should have been the other way around since the Death Eaters never force children to be thrown back into the jaws of abuse and neglect.

But now he was a part of the Dark Order, he would do anything the Dark Lord had to say when he said it. And even better, with him being with Rose again, he would finally have a chance of rectifying the mistakes made by their parents, who should have joined the Dark Lord the moment he asked them; if they'd done that, they would be here, still alive, and they might have won long ago.

"Thank you, My Lord," Harry smiled evilly.

Voldemort smiled back, in the same manner, feeling the old fondness he had for the young wizard return. "I look forwards to hearing of your ideas. They looked intriguing."

Harry had been given a room and was busily unpacking when he heard a knock on the door. Standing still, he picked up his wand and flicked it at the door, his mind going through his repertoire; he could already tell another Death Eater was standing outside.

The door opened. Rose was standing there. She was holding a bundle in her arms. Black robes with a silvery-white mask. His Death Eater garb.

"Hi, Rose," he said, unsure how to greet her. The fact she had come here on such a menial task when a House elf could have done it spoke volumes. She was here to talk.

"Hi, Harry," Rose walked in slowly, eyeing his wand, knowing that he knew more magic than she did even if she'd spent more time recently picking up the Dark Arts. She placed the robes and mask on the bed while Harry flicked his wand at the door, shutting it. "I can't believe you joined."

"You should know me well enough to know I never had faith or trust in Dumbledore, given how he forced me to fight the Dark Lord," Harry replied. "Y'know, this is the first time you and I have spoken in a while," he added mildly.

Rose looked down. "I'm sorry, Harry. I was hurt so much; everyone was saying you were more important than I was, how you saw our parents and I didn't, and how you seemed to care about the muggle lovers more than what we went through-."

Harry snorted, "You are stupid sometimes, Rose. I had always planned on ruining Dumbledore's reputation and revealing his mistakes for the world to see, but now I can do more for our world so then nobody suffers like we did, while we lash out at the muggles. I was forced to do what they wanted when I didn't care. I always had an "it's your problem, you sort it out" view of the Order of the Phoenix. I also joined because you mean more to me than they ever did, and I never wanted you to be alone."

Rose looked down at the floor. "We should have joined the Dark Lord the moment we met him, Harry. He was the only one who truly treated us with respect, while Dumbledore patted us on the head, condescending us and sending us back to the Dursleys."

Harry wrapped her in his arms after deliberately rolling up his left sleeve. Rose had the Dark Mark shoved into her face. "Now, we are on the same side, sis."

Rose nodded in his arms.

"Anyway, we're not the only Potters to join the Dark side," Harry chuckled as he felt his sister jerk in his arms in surprise. "Come over here."

Leading Rose to the bed, he took out his backpack and showed her the history of the family. Rose went through the book slowly, her eyes widening as she read how several of Grandpa Fleamont's sisters and cousins had flocked to Grindelwald, finding his arguments compelling before joining him outright.

And they weren't the only ones.

It looked like James's sisters had joined the Death Eaters; Cleo had been a Slytherin, and Natalie a Ravenclaw, and both were promised great rewards from Voldemort.

"Where are they, Harry? Aunt Cleo and Aunt Natalie, I mean?" Rose asked.

"Mum and Dad wiped their memories and kept them in a box in the Potter vault. I got access to it today and I went to them. They'll be recovered in a few hours. With a bit of luck, they will both be here soon," Harry said.

Rose stared at him, her eyes watering while her mouth was pinched in anger at how much had been kept from them, while delighted they would meet other Potters. "I never imagined we'd meet more Potters."

"There are others, in America," Harry dropped the other bombshell. "Dumbledore kept them from us, another strike against the bastard."

"How do you think they'll react when they realise we're Death Eaters?"

"I hope they accept the fact we're in the right, Rose," Harry told his still shellshocked sister, "and if they don't accept what we're doing is for the good of the magical world, then so be it. We can have our own families."

"Oh, found someone have you?" Rose smirked at him, but he smirked back slightly more evilly than she did, and Rose felt her smile slip away, wondering what he was going to say.

"I saw you and Draco Malfoy. I suppose I will have to ask him what his intentions towards you are," Harry said and she knew he was not joking. He was being utterly serious, and Rose trembled a little. Her brother and she were magically powerful, and while she had shortened the gap by learning and mastering many dark arts fields, she knew it wouldn't take long for him to catch up.

"No, you're not going to hurt him," Rose said firmly.

"I won't, but if he does, I will go after him and use him as a transfiguration study," Harry grinned.

Rose facepalmed, knowing she'd lost.

But then Rose was surprised when Harry rolled up her sleeve, revealing her own Dark Mark before he rolled up his sleeve. "I wish we'd gone into the same House, and did this at the same time, sis," Harry whispered.

Rose touched his arm tenderly. "Me too, bro."

Over the next month, Harry proved his worth as a Death Eater to the others very quickly. Using his creative knowledge of spell casting, he was able to create bolts of lightning which tore through the Houses of Parliament and Buckingham Palace and other parts of London before he turned his attention to the Order of the Phoenix, destroying Number 12 at once.

When it was revealed Harry Potter was a Death Eater, he and his sister, Rose became reviled, but the Order was completely outmatched since so many had joined to gain Dumbledore's protection and because they relied too heavily on him to win the war, they were stuck.

Harry didn't give a damn how they felt. He was too busy getting to grips with his new life, and since the Dark Lord was concentrating on his goals, it was easier than ever to save muggle-born children, especially when they were being abused. In his first week as a Death Eater, Harry personally tortured nine different families for torturing children no older than three for exhibiting magic.

The Death Eaters quickly came to respect him. He was powerful and brilliant, and when the Dark Lord announced a celebration for a victory in the Ministry and their families came, Harry was there with Rose. Quickly he won the hearts of several of the children there, some of whom had been blood adopted by the more willing dark families. He conjured a plushie dragon, enlarged it, and flew it around the room, to the delight of the children.

Rose, who was attending with Draco, smiled at him, enjoying the look of peace on his face. She smirked when she saw a few witches their age looking at him with interest, and she hoped that Harry and she had a happy ending. At the same time, she wished they had both joined the Dark Lord from the very start, instead of waiting this long.

Author's Note - I've been asking around lately, wondering what it would take if a sibling of Harry became a Death Eater even if sometimes I have problems working it out. The idea is fascinating to me, mostly because Harry never knew his parents, so why should he feel that type of loyalty? In this story, Harry and Rose both grew up abused, damaged, and they saw no reason to be loyal to Lily and James' memories.
