Disclaimer: anything recognizable I do not own.

I am going to be mainly focusing on Damien Potters group, not Harrys. I hope you don't mind. Also, not only did I get this story from the Harry Potter books but also from Dean Brody's song brothers. I was listening to it and was sort of wondering what would happen if Harry Potter had a brother to look out for him. The war never ended. It just kept getting worse until they forcibly enlist people into the fight.

Damien Potter was Harrys Idol. He was always there for him when his own father couldn't be. He was a fifth year. He was turning 16 that day. Harry couldn't wait to give his brother the present he had made in class. Harry was only a first year and thought Damien hung the moon. Then again so did everyone else. Damien was a happy, funloving student and was one of the most popular students in the school gaining friends in all houses with his good nature.

With a war going on, to Harry, Damien had been his everything. he taught him to fly a broom, to cast spells, to catch a snitch. Their father had died five years before, so Damien became both brother and father. He also became mother as their mother died weeks before school started up.

However, with a war raging on outside the doors of Hogwarts, things would not be happy between the broken family of two for very long.

It was his sixteenth birthday and Damien was sitting talking with his roommates, Oliver Woods and Percy Weasley. His two best friends. As Harry made his way over followed by his own friends, Neville his godbrother, Ronald and Hermione.

The moment Harry was seen, Damien quickly ended his conversation and turned his focus to the eleven-year-old. "Hey kiddo," Damien said grinning, roughling his already messy hair.

Harry just grinned back not bothered by the action. He was too excited to give his brother his birthday present. "I got you a present."

"Did you now," Damien said surprised, he wasn't able to go to Hogsmeade and he'd not requested money for owl order. "You didn't have to do that Snidge."

Harry handed him the package likely more excited then the teen who was about to open his gift. Damien opened it slowly drawing a pout from his brother. When the package was opened, it revealed a necklace. It was similar to a flat of metal but had his name, date of birth on it but also Demon which was what their dad had called him. It was a lot like the dog tags muggle soldiers wore. Something that both of them had been interested in growing up. Their grandfather on there mothers side had had a set and she had told them stories…back before she went a bit crazy seeking revenge for the death of her husband.

"Merlin snidge," Damien said pulling him into a hug knowing that he had to have worked hard on it. The dog tags reminding them both of a better time when they weren't just a family of two. "Thanks kid, I love it."

Harry just grinned. "any plans for your birthday?"

"Donno, maybe we could go get cake from the elves and eat so much mom would have our arses," Damien suggested mentioning their parents hurt but he would never let his brother see that, "Like we use to do with dad. Do you remember that kiddo?"

Harry nodded quickly though he mostly remembered through the stories Damien had told him. Damien hadn't wanted Harry to forget his father. Despite being gone continuously during war efforts. He was a good father. A good man. It wasn't fair they lost him so soon and their mother a short time later. Still, there losses were one of many in the war which tore apart families. "Yeah, it sounds like fun."

The owls began arriving and everyone froze at the red envelope. Damien closed his eyes knowing before it landed. As did his friends. They had expected it to come but they didn't expect it so soon. On his birthday. Usually they would wait a few days the send the red enveloped letter. They knew it was coming, Harry however did not.

He froze unable to believe it. He began shaking violently. The eleven-year-old couldn't believe it was real. He silently wished it wasn't real, but it was as Damien took the letter with his name on it. "no no no," he said desperately. "Please no Damien."

"Snidge," Damien said softly. "It will be okay Snidge."

"NO," He shouted running out.

Everyone knew what they red letter meant. It meant that he was inducted into the hit wizards. It meant he was going to war and fighting the death eaters. Damien got up and took off after Harry calling his name.

Despite their only being a couple seconds difference in their leaving the great hall. Damien couldn't find his brother anywhere and returned to the common room hoping he had went back. "Damien," Percy said looking to his friend. "I am so sorry."

Damien punched the wall angrily. He had known it was coming. No surprise. Still the broken look in his brother's eyes tore his heart apart. It wasn't fair. This war should have ended long before. Before kids the age of Hogwarts students was forced to go fight battles. Before eleven-year-old children knew what it was like to lose their father, there godfather and honorary uncle, there mother and now potentially losing the only family he had left. "Fuck Percy, I need to find my brother, where are yours? They can always find him."

"Here," Fred said leading Harry into the room. All of them had dark expressions on their faces. As if he had already died.

"Harry," Damien said gently crouching down so he was closer to his brother's height.

Harry wiped his eyes trying to be brave for his brother but he was terrified to lose him. At eleven, he did not really understand why it had to be him. Why he of all people had to leave for war, to fight battles. "Why does it have to be you? Damien there's got to be a way to get you out of it. Please you can't leave me too."

"Harry," Damien said forcing him to look at him. Needing his brother to understand. He may not want it but he knew what he had to do. He would do this for Harry. No matter how hard it was, he would do this for his brother. "I have to do this."

He shook his head defiantly, "No you don't."

"Harry, this...I have to do this. It is what brothers are for," Damien stated.

"What do you mean," Harry demanded not understanding what that had to do with anything, "You could die I can't lose you too. Everyone...they've killed everyone I can't lose you too Demon."

"Snidge, I need to do this," Damien said gently knowing in his heart it was what he had to do even if at the moment it hurt. "It is what brothers are for. I need to fight so you never have to. So, you can live free. So, you never have to face them."

"Someone else can fight," Harry said.

Damien kissed his forehead. "No Harry, I have to fight. Don't worry, I will come back for you Snidge. I won't let them take anything else from you kid. I promise. I will find a way to end this, so you never have to face this choice."

"Promise you will come home. I can't lose you too."

Damien looked him in the eyes, "I promise I will not leave you alone Harry. I promise I will do everything in my power and come home to you."

Damien stood up and looked to Percy his features cool and serious, needing his friend to make him a promise. They had spoken about the possibility but now that it was here, he didn't feel prepared. "You take care of my brother, summer you take him home with you if I can't."

Percy shook his head shocking everyone, "I can't Damien. You know as well as I do that my birthdays in a week. I am right with you top of the year, I turn 16."

No one had put that together, except the others facing the decision. "What," Fred demanded shocked having never thought that was even a possibility. His brother, his rule following prefect older brother couldn't possibly be going to war. "What do you mean you...no no way."

Percy looked to the twins knowing they would take it worse than Ronald. "I'm sorry Fred, George I thought you would know. I will get a letter on my sixteenth birthday and I have no intention of fighting it. One from every family. I won't let it be one of you. Bill and Charlie were gone before they started enlisting. I go or one of you will have to and I can't let them do that."

Damien looked to Oliver knowing his older brother was in the hit wizards. He would not have to enlist, "Don't look at me mate. I'll be out there watching your back and keeping you both alive. I don't got the grades you do but I put down my name. I'll be gone before Christmas."

Damien wasn't entirely surprised but they had never made a final decision on it. At least that they spoke of. "This isn't fair," Harry stated angrily. He was losing his brother and his brothers friends. It just wasn't fair. "Why can't the adults fight the war."

"Because they failed to," Percy stated knowing nothing he could say would make it easier. "They had their chance. Now its falling on our heads and we won't let it fall on yours."

"So, because the ministry fucked up you have to go fight," George demanded angrily.

Percy gave his brothers a hug. "It's exactly as Damien said. It's what brothers are for. Now, you both take care of Ron and Harry. I spoke with dad, he agreed that if Damien got enlisted Harry can live with us. You take care of him or we both know Damien will come back and kick your arses."

They nodded completely serious. Harry and Damien were as good as family already. "We promise," Fred said seriously. "When...when do you go?"

"The next training group start October 31st so we have a month, my birthdays October 14th," Percy stated.

"I'll get my letter soon, I'm already sixteen but they send the freely enlisted letters by October 1st," Oliver stated.

Damien looked to his brother, "I will come home Harry, I promise and this entire month I will spend every minute with you," Damien promised. "Okay baby brother?"

"I don't want you to go," Harry stated.

"I know Snidge, I know now we need to go down, bug the house elves and get lots and lots of cake and Ice-cream and chocolate. We will eat it till we puke and I think that we can have a sleep over in my dorms."

"I believe there's a girl I might stay with in the old classroom," Oliver stated knowing the two of them would need more time to come to terms with being separate. One at school and one at home wasn't the same as one going off and fighting a war.

Percy nodded, "I am sure the twins will put me up for the night, just the two of you for the night."

Damien gave them a grateful smile, "Come on snidge. Buck up. It's my birthday, no tears on my birthday."

He didn't look happy but followed Damien out anyways. He'd do anything for his older brother and if he needed him to buck up, he would. He might not be happy about it but he would do it anyways. "Will the kid be okay," Angelina asked worriedly. "Damien's been worried sick about him."

"You would be too," Percy said bluntly. "There grandparents were killed in their home when Harry was one. There dad was a hit wizard, high up. He was killed back when Harry was 6 and Damien was 11. Their mom died Last summer. There godfathers or uncles are currently Missing in Action, Sirius Black should have gained custody, but he was reported missing before their mother's death. Believed dead. There uncle Remus went undercover in a group and was never heard from again. Both are either dead or worse. They are all each other has. No other family except some muggles they have never met."

"I never knew they lost that many people," Fred stated horrified. He had lost family, uncles and aunts but their immediate family was still intact. He still had both parents and even living grandparents. None of his brothers had been killed. He couldn't imagine how the eleven-year-old felt.

Percy looked to the twins. "Which is why you need to take care of the kid for Damien because we can't. He will be coming to live with us during the summer since there will be no way for us to get the summer off. It's up to you both to take care of him."

"We will," George promised, "you're sure there's no way for you to get out'?"

Percy gave George a hug. "I wouldn't even if I could. Sorry Georgie. It needs to be done. Someone has to fight and this war has to end. Before there's nothing left to fight for."
