This is platonic and cute. Sibling relationship. The feels in this hurted me.

Dumbledore P.O.V.

Looking at Y/n, I'm reminded of the terrified boy who sat in my office, holding a crying baby girl, without a clue in the world what he should do. The girl's mother had died in labour, and James had cared for the girl for about a week. His classes became too over whelming, and he couldn't do anything with all the responsibility he has as Head boy, Quidditch captain and the rest.

Him and a few friends took turns to take care of this little angle, but they just couldn't manage, and all the teachers forbid him to bring her to class. So now, here he was, explaining the situation to me, tears in his eyes, his precious baby girl in his arms.

"I'll take care of her Mister Potter. And you would be welcome to visit her any time you'd like," I had said with an all knowing and warm smile. I felt a stabbing pang in my chest for this little girl. So young, and unable to be with her birth parents for a while.

He laid the baby girl down in a cradle by Faux's resting post. As soon as he left, she started crying for her father. After I had calmed her into a sleep, I left the room and wept. No child could be treated like this.

Dumbledore P.O.V.

I had just received the news that James and Lily Potter had died. They would have come to collect Y/n this afternoon.

I had left Y/n with Severus, who didn't seem to mind caring for her, and cried in my office. Y/n was too precious for this world. She had this light in her that no one her age would ever have. I had taken Harry to the Dursleys, hoping that they would care for him like I was caring for his half sister. Y/n was given her mother's surname, Fiendfyre. I resolved not to tell her of her true identity till she was ready.

Dumbledore P.O.V.

"Dumbledore! Dumbledore! Come quick! It's Y/n!" The groundskeeper, Hagrid burst into my office. I had raised Y/n Fiendfyre for five years, rather successfully might I add. I had entrusted her in Hagrid's care for the day, as he had no classes to teach or pressing meetings to attend. I had rushed out behind Hagrid, and paused when I saw Y/n shrieking in delight as a blue whisp floats around her, taking the shape of a brown owl. Just like her mother.

Hagrid bellowed in delight, and I joined him. She has potent energy, that little girl. She's going to be a bright one when she starts going to Hogwarts. I think I might be more excited than she is for her to start attending.

Y/n P.O.V.

I didn't receive a letter like the others. I received a "You are attending Hogwarts in a month, by the way," from my adoptive grandfather Albus. I called him Papa Al. He was so proud, that he had framed the letter in his office before I had even got a chance to read it.

Hagrid had taken me to Diagon Alley to buy my school supplies. When we stopped to get ice cream as a treat, Hagrid had bought me a brown owl, with the most stunning eyes. When I looked at them, I could see the stars.

"She 'ot a bi' of a gift that un', 'ey told me so," Hagrid said, watching me examine the bird.

"She's perfect! Thank you Hagrid!" I barreled into his arms, giving him a hug in gratitude. I heard him sniff above my head, and I pulled away, to see him crying.

"Oh, don't cry Hagrid! When you cry, I want to cry," I say, my tears welling up.

"Oh no! Don't you dare!" Harris bellowed, offering me a hankie large enough to be a blanket.

I smiled, "I think you need it more than me," I said, patting him on the back.

One year later
Y/n P.O.V.

I'm now attending Hogwarts classes officially. I am currently starting my second year, and I am sitting through the sorting ceremony. I'm watching Minnie read off the names of students.

"Potter. Harry," she reads, and a chill runs down my spine at the mention of his name. The name sounds familiar, but not because of the fact that he is the most well known wizard other than Papa Al and Baldey-mort.

I make eye contact with Harry through the crowd, and smile. I hope he gets sorted into Gryffindor. He'd be a lovely addition to our house.

"Gryffindor!" The hat bellows, and my whole table stands up, cheering. Harry Potter is in Gryffindor.

Y/n P.O.V.

I had become good friends with Harry Potter and his two friends. I rather enjoy speaking with them. I am technically friends with everyone in school, but I mostly spend my time with Hermione or the twins. What a contrast, I know.

I was walking through the Forbidden Forest to feed some of the creatures to give Hagrid  a day off, when a large black dog jumped me over, sniffing me.

"Why hello! Aren't you just the sweetest thing!" I say, petting him. The dog gave me what looked like a lopsided smile, and ran off.

I started the habit of leaving him some food in a dog bowl. I had given him the name of Polly. He looked like a Polly, even though Polly is a girl's name.

Every weekend, I'd go and have a chat with him. Yes, he could talk. It was so cool.

But one weekend, he didn't show up. I waited for two hours, at the spot we'd usually meet, and he wasn't there.

After about two months of this happening, I gave up returning to the spot. I still left food out though.

Two years later

Today marks the beginning of my sixth year. I'm officially sixteen. I take my seat in the Great Hall, and listen to the speeches, the sorting ceremony and all the announcements. I spot a new teacher. She looks kind of like a pink toad. I'm going to call her Toadstool. Or Pink Mushroom. Pink Mushroom has more of a ring to it.

A few weeks into the term, Harry and I get called into Papa Al's office. He made us both take a seat.

"Now, what I'm about to tell you is going to be a bit of a shock," he said, "but you two are half siblings."

He explained how my father, James Potter, and my mother Ryona Fiendfyre had me in their seventh year of school, and how my mother died during childbirth. My dad and three of his friends tried caring for me, but it became over whelming, and my father asked Pappa Al to care for me. My father promised to come back as soon as he had his life in order.

"There was nothing he wouldn't do. I could see it in his eyes. He had this love for you, that I had never seen before in his eyes. He would do anything for you," Papa Al had said.

I looked over at Harry, tears in my eyes. I grabbed his hand. "Hi brother," I say giving his hand a squeeze. He squeezed my hand back.

"It's nice to know I still have family that loves me," Harry said with a sad smile. I mean, we were practically like siblings before, but now that we were officially related...it felt surreal.

Life got tougher the older we got. But in the end, I still had Harry.
