Harry Potter But AU?

Harry's POV

"Dobby." Harry called once he was in the room of requirements.

"Who called Dobby?" Dobby said after popping into the room.

"Hey Dobby, I'm Harry Peverel and I would like to offer you a job."

"Mr. Peverel want Dobby as his house elf?" Said Dobby with tearful expression.

"First of all call me Harry. Second, Yes, I would. Do you want to be my house elf? It would be fine if you just want an employment..."

"Yes Dobby would like that."

"So let's talk about how much shall I pay you."

"Harry Peverel would pay Dobby?" You could see the concept of payment hasn't even made itself known yet in the house elf's mind.

"Of course, you are a free elf, you deserve to be paid." Harry knew from the books that Dobby wanted freedom and payment.

"So Harry Peverel don't want Dobby being his house elf?" Dobby asked confusing Harry.

"Of course I do, but you are free, don't you want to stay like that and be my house elf?"

"Dobby wanted being Marcus Potter's house elf until Marcus Potter told Dobby's old bad master to punish Dobby. Now Dobby only want a master that is good, who won't ask Dobby to do bad things and won't do them himself."

Harry thought he got it, in the books Dobby wanted canon Harry to be his master but canon Harry never suggested it so he decided to stay free.

Now with Marcus betray, Dobby only wanted to have someone else to serve.

"O.K. If that's what you want, you can become my house elf."

"Dobby is so happy master want him."

A flash of light appeared and Harry could feel the bond between him and Dobby.

"Now that we are bonded I have two requests. First of all, you should know when I'm outside of Hogwarts, I'm usually in the muggle part of the world, which means I can't have you call me master as in the muggle world It it's forbidden so from now on call me Harry."

In truth Harry wasn't comfortable being called master so he used it as an excuse.

"Great ms.... Harry is letting Dobby call him by his name, Dobby is grateful to have such a wonderful mas.. Harry!"

'It appears that it would take him some time getting used to call me by my name' thought Harry before telling him the second request.

"Secondly, I need you, whenever there is no one in this room, Whenever we are in class or in summer vacation, to come outside this room, walk three times where the door is supposed to be while thinking about needing to hide things and come inside the door that appears, the room is messy and I need you to organize it without touching any of the dark magic, can you do it for me?"

"Yes, mast... Harry!"

After which Harry when to sleep, he really needed one.

A day later

Luna's POV

Luna was so happy, her childhood friend is safe, the school won't close, and most importantly, there are no tests this year, which means she can use the next few weeks to learn magic with her Harry.

'Her Harry? Where did this thought came from?'

Though as much as it embarrassed her, if she was honest with her self, she might have a crush on the black haired boy with his tall, muscling figure, emerald eyes and powerful, yet controlled, colorful yet orgenized aura and of course, the peace she had when she was near him, with no small creatures flying near in and out of his ears. Yes the boy was perfect, if only.... A small sigh escaped her lips, if only she didn't have a competition known as Daphne Greengrass, a girl too pretty to be real, a girl who Luna felt was trying to steal her friend and knew from the Wrackspurt that came to Daphne's ears and the way they danced when ever she looked at him, that she was trying to use him.

It was the reason she didn't like her, it was the reason she was competing with her whenever they were having one of the muggle lessons about biology once a month in which Daphne joined. She wanted Harry to see she was much better then that girl.

Just like now, in an abandoned classroom as Harry didn't want Daphne to know about the ROR (a fact that made her happy every time), and they were learning about blood.

"Bone marrow is a spongy substance found in the center of the bones. It manufactures bone marrow stem cells and other substances, which in turn produce blood cells. Each type of blood cell made by the bone marrow has an important job. Red blood cells carry oxygen to tissues in the body..."

While Luna found the subject fascinating, a quick look in the direction of Daphne she could see the girl had much more fire in her eyes then usually.

'I wonder why?' Luna thought, before putting her entire attention back into learning to the 'professor'.

Daphne's POV

As Daphne heard about the bone marrow's job and the muggle's way of transplanting it her eyes lit like fireworks, her sister's blood curse can be cured!

It's why she stayed after the 'class' her business partner taught.

"Why didn't you tell me?"

"What?"

"That the only thing we need to do to save my sister is taking out her old blood stem cells in and create them again with potion?"

"Oh, that. Because it wouldn't work. As I told you before, while the curse might be in the blood, although I wouldn't know without studying her blood. Even if it is, the bone marrow that you would regrow would be identical to the first, which means you would accomplish nothing."

"And what about transplanting blood stem cells from someone else?"

"While that might work, thought wouldn't know with out learning what is that curse and if it is blood related, you would need someone who is a perfect match to donate their blood stem which based on what I can tell, would be much harder to find as I don't know if magical people's bone marrow is affected by magic or affect their magic, I know you wouldn't want to save your sister only to mage her a squib, and even if we succeed in everything, she could die from the procedure.

Even if the worst doesn't happen, even if everything is fine, her descendants would still have to suffer from the curse."

"So the only way we have is change her DNA? Her, as you called it in your book, vary being?"

It was at that point that she started screaming and crying

"There might be another way, but right now I can't see it." Even though she could barely see him, Daphne could heat the helplessness in his voice

It was then that Harry did something Daphne didn't expect, he hugged her.

"Don't worry, we are making progress. We would save your sister, we just need time."

It was then that Daphne decided to make sure Harry and her get the device that give a person more time, as she would do anything to save her sister.
