A/N: Hey everyone! After seeing a lot of Tumblr posts about this, I finally decided on doing something about it. So my two loves HP and OUAT collide in this story. I hope you like it. Please tell me what you think! R&R!

Chapter 1: King's Cross Station

"Emma, come on, honey, it's time to go!" Mary Margaret said as she knocked on the girl's door.

"Coming!" Emma replied as she attempted to push her trunk out of her bedroom.

"Need a hand there, Emma?" David said smiling as he saw the blonde's effort. "Wingardium Leviosa" he said, flicking his wand and guiding the trunk down the stairs, outside their country house and into the van.

"Ugh, so not fair, David!" Emma shouted.

"Well, that's why you're going to school, to learn magic, young lady, and you know you can call me dad" he chuckled affectionately while ruffling Emma's hair.

"All set, then?" Mary Margaret asked.

"Yeah, just let me go get Merlin" Emma said as she ran up the stairs. She came back down holding a big cage with a silver owl. "Good boy, ready to meet your new home?" she cooed as her owl hooted softly inside his cage.

"Mom, why can't I go to Hogwarts too?" a small brown-haired boy with big eyes looking up to his mother asked.

"Not yet, Henry, in four more years" Mary Margaret replied as Henry's face fell a little.

"But you'll get to see this really cool train at the station, the Hogwarts Express" Emma chimed in, trying to cheer her adoptive brother up.

Emma Swan was thrilled to finally go to Hogwarts. Three years ago, she wouldn't have imagined her life would be like this. She had been living in muggle foster homes until she turned 8 and her magical abilities started to surface. When she accidentally set her 13 year old foster brother's hair on blue fire because he was bullying her, the Department of Magical Law Enforcement had showed up at her doorstep to clean the mess, erase memories, and place Emma under the care of a magical family, the Whites.

At first it had been too much for Emma, and she acted shy and quiet around her new family, trying to grasp in her 8 year old head that she was a witch, that there was a whole world she never thought existed before, and that more importantly, she had a family that actually loved her as she was. Soon enough, Emma began to feel more at home with the Whites, even though she still struggled to call them mom and dad, and wondered why on earth did they still want her.

They arrived to King's Cross Station in a hurry to get to Platform 9 ¾.

"Emma, wait up, slow down, there's enough time!" Mary Margaret said as she grabbed Henry's hand and tried to keep up with Emma, who was enthusiastically pushing her cart to get to the platform.

"I don't wanna be late!" Emma replied as she kept up her pace and had both parents rushing behind her into the brick wall of the platform.

"Emma, be careful. You're gonna…" she heard David's voice behind her but Smash! Too late! Her cart had bumped into a brunette girl's cart and both their trunks now lay on the ground while Merlin hissed angrily.

"Oh crap, I'm so sorry. I didn't mean to" Emma said.

"Emma, language!" she heard Mary Margaret's voice approaching.

The other girl chuckled haughtily at Emma's swearing as she stood up and shook the dust off her dress.

"It's ok, I'm sure it was just an…" the brunette replied.

"Well, well, if it isn't the White's stray dog. I knew you would only be trouble when I heard they had adopted you. Looks like you're proving me right" a tall dark haired witch stood looking down at Emma with disdain.

"Don't you dare talk to my daughter like that, Cora" Mary Margaret said angrily.

"I was just pointing out the obvious. Come on Regina, you don't want to be associating with this scum of unknown origins and questionable upbringing" Cora sneered, as a scared but proud Regina trailed after her mother leaving Emma dumbstruck at the lady's rudeness, but feeling insecure at the reminder of who she was.

"Who was that?" Emma spat angrily.

"That is Cora Mills, head of the Wizengamot, and she hates your mother, because she hated her mother, because… It's complicated," he sighed. "But just stay away from the Mills in general. I don't know about their youngest daughter, but they've all been in Slytherin so far, and let's say they're one of the few families after Voldemort's time that still believes all wizards and witches should all be pure blood." David explained.

"Is that why she said all those things? Because I'm an orphan and don't know who my parents are?" Emma asked, trying to hide the tremor in her voice.

"Emma, you're not an orphan." Mary Margaret interjected.

"Yeah, you're my sister!" Henry added trying to cheer her up.

"Thanks kid…" Emma sighed becoming wary of her near future at Hogwarts and this Regina Mills. "Well, I better get going… I'll write to you when I get there" she said as she hugged David and Mary Margaret.

"I'm sure you'll make many new friends" Mary Margaret said.

"And remember that even if you get sorted into Slytherin, we love you no matter what" David said teasingly.

"Ok" Emma smiled. "Bye buddy!" she said giving Henry a hug. "Write to me ok? And I'll see you at Christmas"

Henry nodded as she turned around and saw Emma jump inside the train, a mass of blond curls disappearing among the rest of the students.

"Hey, is this seat taken?" Emma asked a boy with brown hair that was wearing a Gryffindor scarf. He looked older than her but he couldn't be older than 13.

"Nope" he smiled as she sat down in the seat in front of him. "Name's August"

"I'm Emma, Emma Swan" Emma replied. Emma had chosen to keep the name on her birth certificate instead of adopting the White surname. Sometimes it made her happy to remember that there was a family that accepted her for who she was, but other times it reminded her of a past full of pain and misunderstanding. But it kept it real, Emma thought. It was her way of guarding herself against abandonment or rejection.

"Well, nice to meet you Emma Swan. I'm a second year" August said.

"Really? Cool! Tell me everything about Hogwarts. I don't want to look like a complete moron when I get there. I mean, I have heard about Hogwarts , my adoptive parents are both wizards and my neighbors are the Weasleys, but they only have baby Rose, not anyone that is actually my age, or going to Hogwarts at the moment, you know?" Emma said without catching her breath.

August chuckled "A bit of a rambler, aren't you?"

"Sorry, I do that when I'm excited or nervous, and right now I'm a bit of both" she replied.

"Nah, that's ok. Well, there are some things I can tell you about Hogwarts that you won't hear from anyone else, knowledge from the legendary Weasley twins…" he started.

"August! We were wondering where you were hiding!" a tall girl with straight brown hair with a red streak and another brunette with her hair on a neat ponytail stumbled into their compartment.

"Hey there, my favorite ladies! Emma, these are Ruby and Belle. They're first years as well. Guys, this is Emma, my new friend. If you want to win points, make friends with this one, I'm telling you" he said pointing to Ruby. "Her grandma is one of the teachers."

"Are you kidding me? You go for a year thinking you'll be away from your parents but now I have a strict grandma watching my every move" Ruby sighed in defeat.

"Oh, come on, she's not that bad" August said.

"Right, wait till I start taking her class. She won't cut me any slack." Ruby replied.

"So guys what house do you want to be in?" August asked.

"Is that even a question? Obviously Gryffindor!" she replied confidently.

"Hey, I'm already liking you!" Ruby smiled "Belle here wants to get sorted into Ravenclaw and I can actually see her there. She's a big nerd!" she said affectionally.

Emma enjoyed the playful banter with her new friends the rest of the way, so much that she forgot about the incident with Regina earlier. This was going to be a good year, Emma thought to herself as August showed them a trick that made your nose grow when you were lying.
