Summary: Aurora Lillian Potter does her best to keep her "baby" brother out of trouble because of a promise she made long ago. Of course, the fact that her brother is Harry Potter, the Boy Who Lived, tends to make the job more difficult. Add on top of that her attempt to be her own person and not just "Potter's sister," and there is bound to be some drama. All that's left to say is, good luck, Aurora.

A/N: Hi all, this is my new Draco/OC story, some things will be similar to my first story The Dragon's Light, so if you read that one you might recognize a few things. This story is going to start with GoF and will go through the series form there. I hope you all enjoy and please review so I know how I can improve my writing! Without further ado, here is the story!

PROLOGUE

"Picture!"

A surprisingly loud voice came from a little girl of about two, as she posed in the living room, clearly ready for the picture that she had called for. Her mother laughed while holding her baby brother and her father shook his head with a chuckle, "Of course, darling. Whatever my little girl wants." This was generally the response this particular little girl received from her father, as she was after all his little princess.

With that, the family gathered in front of the camera, all smiling as the flash went off. Of course the little girl wanted to take a second one "just in case," but it was useless given the wailing her baby brother had started as soon as the camera flashed. She was angry at first but she didn't want to scare her baby brother again, so she gave in. However when she looked at the picture she smiled and decided they had no need for another one because this one was perfect! She was standing front and center in her Dorothy costume, her parents on either side dressed as Glinda and the Wonderful Wizard of Oz, the photo was completed by her baby brother dressed as Toto sitting in her basket.

She just knew this Halloween would be special and she was happy to have captured it in a picture. Maybe next Halloween they would actually be able to go outside. She said as much to her parents who exchanged a look before her mother smiled and said "Maybe, darling."

The little girl frowned because she knew that when her mother said "maybe," it really meant "don't get your hopes up." However, she got over her moment of sadness because as long as she got to spend Halloween with her family, she would be happy. And if she got to choose their costumes again. When she repeated this to her parents, her mum's eyes got watery ("allergies" she always said) and her dad picked her up and told her with a proud smile, "That's right darling. Family is the most important thing and you must always remember that."

She just smiled right back at him, "Don't worry, daddy. I will!" And with that, he put her back down and she started playing with her brother as their parents watched on with smiles on their faces.

As the night wore on, the little girl ended up making many more promises to her parents that night, after the bad man came.

"Go with your mum, always remember how much I love you darling." "Don't worry, daddy. I will."

"Stay hidden and stay quiet. Always know that I love you." "Don't worry mummy, I know."

"Make sure to always take care of Harry, darling." "Don't worry, mummy. I will."

As that little girl grew up, though she forgot the people she made the promises to, she vowed to herself that she would do everything in her power to never break those promises. Never.
