Aria Kendra Dumbledore Prewett is the only grandchild of Albus Dumbledore. Her parents died during the first war with Voldemort. And Albus became her legal guardian along with Aberforth. Before she started at Hogwarts, she spent the school year with Aberforth. She was born on September 13th 1978, so is a year above Harry and the other two. She was so proud to be placed in Gryfinndor like the rest of her family and is a true gryffindor in every sense of the word. So much in fact her patronus is a lioness and in future becomes a lioness animagus. But we're getting ahead of ourselves. This story starts in her second year when the Golden Trio starts at Hogwarts. So let the story begin.

Aria's POV

I'm lounging in the study reading my school list as Dotty sleeps on my shoulder. She had been out all night hunting after delivering my letter. Poor girl is exhausted. "Something wrong?" my grandfather asks as I frown at the book list.

"No, just wondering who's the new defense teacher" I tell him.

"Quirrell is actually" he states.

"Didn't he teach Muggle Studies?" I ask confused.

"He did, but we already have a muggle studies teacher and he did very well in Defense Against the Dark Arts" he explains.

"What happened to Professor Green? She was an amazing teacher" I state.

"She resigned and returned to the ministry" he explains. "But I assure you, Professor Quirrell is more then capable at teaching the class" he assures me. "Anyway, a new muggle-born who is starting at school this year needs a guide for Diagon Alley. Would you be interested in taking her and her parents around?" he asks.

"I'd love too" I tell him. "But won't they be confused why a twelve year old is being their guide?" I ask him.

"I shall explain hings to them, we leave shortly" he tells me.

"Of course we do, let me go put Dotty in my room and grab my cloak. Wand and money pouch" I tell him. He nods his head and I do as I said I would. I come downstairs and he hands me a key on a chain. I smile and put it around my neck, it's a key to my families vault. I have my cherry wand in my wand holster, that he had gotten me for Christmas last year.

He apparates us to a place under a bridge. "Follow me" he says and I do so. About five minutes later we arrive at a two story house. He knocks on the door and a man in his thirties answers. "Good Morning Mr Granger, I am Albus Dumbledore and this is my granddaughter Aria. She will be helping you and your family today" he states.

"Come in" Mr Granger says and lets us in. He leads us to the living room. Where a woman and a young girl with bushy brown hair are waiting. "Jean, Hermione this is Albus Dumbledore and his granddaughter Aria" he says.

"You're the headmaster" Hermione says shocked.

"I am" he says with a twinkle in his eyes. "Being headmaster, I don't have much free time. So my granddaughter has kindly agreed to help you today" he states.

"But she's a child" Jean says.

"I am, but I am in my second year at Hogwarts and have grown up in the magical world. I can tell just as much as my grandfather and I can recommend some extra books Hermione could read" I explain.

"Extra books?" Hermione asks excited.

"Yes, I feel you deserve to be able to read as much about your new world as you want" I state.

"Mum, dad please can she show us around?" Hermione pleads. Her parents agree. Grandpa gives them the address to the Leaky Cauldron and left. Hermione and I sit in the back sit. As her parents drive us there. "What's the school like?" she asks.

"It's a castle, there are four houses at Hogwarts. No matter what house you'll be in, it will be like your family while you are at Hogwarts. We have multiple greenhouses, you'll learn to fly on a broom. You don't have to be there the whole year, you can come back here Christmas. First years arrive by boat from the train station, but afterwards they arrive by carriage" I explain.

"Where is Platform 9 and 3/4s? We've been to Kings Cross before, but never seen it" she states.

"It's hidden between platforms nine and ten, I'll show you on September 1st" I tell her. The car stops. "Good, we're here" I say.

"Are you sure this is the right place?" Mr Granger asks.

"It looks like a broken down old shop" Mrs Granger states.

"It does to the Muggle eye, what do you see Hermione?" I ask.

"I see a pub, a sign with a leaking cauldron outside" she states.

"Don't worry, once you enter you'll be able to see it in future if your with Hermione" I assure her parents. I lead them all inside and her parents look around in surprise. I waved at Tom and headed for the back. I tap the right brick with my wand, before holstering it. "Welcome to Diagon Alley" I tell them. They look around in awe.

"Can we go to the book shop first?" Hermione asks.

"First you need money to buy books" I tell her.

"We have money" Mr Granger states.

"Muggle money, you need wizard money. For that we have to go to Gringotts" I tell them pointing to the large white building. I lead them in and head over to front desk. "Hello Gornuk, the Grangers would like exchange muggle money for wizarding currency. Also may someone go fill my pouch with money from my vault?" I ask offering him my key.

"Of course Miss Prewett, I shall have Griphook go get your money and Hemlock can help the Grangers" he says gesturing to a desk. I thank him as he took my key and lead the Grangers over to Hemlock. Or how I like to call him, the clever goblin. After the exchange they had 50 galleons, 2 sickles and 12 knuts. Griphook appeared with my pouch and I thanked him. Taking it and my key.

"So you wanted the book store?" I ask Hermione.

"I think it best we get the essentials first Hermione" her mum states. "Leave the books for last, so we know if we have enough money to buy extra books" she explains.

"Ok mum" Hermione says looking deflated.

"How about school robes first?" Mr Granger suggests. We agree and I lead them to Madame Malkin's. She did Hermione's robes quickly. We then got her a cauldron, dragon hide gloves, phials, telescope and scales. Then get her wand, it was entertaining to watch. She final found her wand, vine 10 3/4 inches with dragon heart-string core.

"Time for your books" I tell her and she squeals. I chuckle. I'd be surprised if she wasn't in ravenclaw, though it'd be nice is she was in Gryffindor with me. I lead the way to the book store. The shop keeper immediately helps them with the required books and I went to pick out a couple extras for Hermione to read. I think she'll enjoy Hogwarts a History along with some other books on our worlds history.

She loved them. We headed to the ice-cream shop and got an ice-cream each. "How will you get home dear?" Mrs Granger asks me.

"Floo, I'll be fine" I assure her. As I put the last of my stuff in my bag. Which has an undetectable exchange charm on it. "I'll see you guys at Kings Cross on September first at 10:30" I tell them. They nod and Hermione hugs me. Before they left. I floo home and see grandpa by the father looking a little frustrated. "Something wrong?" I ask him.

"Harry Potter has not been receiving his letters, if it continues I'll be sending Hagrid" he states.

"I'm sure he's fine grandpa, you'd know if he was in trouble" I state. "What's for dinner?" I ask.

"You're favourite" he states and I smile. I sit down by the fire and start to read my new spell book. Wondering what this year will bring? What house Hermione will be in? What do I say when I see Harry Potter? I don't want to mention his dead parents or any sore subjects. I push the thoughts from my mind and focus on my book.
