So here is my try are a Harry potter story. First off any flames will be laughed at but useful comments are appreciated. The time set starts during year 4 and I will continue to write stories throughout the years and possibly after the war. No matter what I will not change my character or any pairings but any other ideas are welcome.

I do not own harry potter they are owned by JK Rowling.

Chapter 1

Here's a twist

Night has fallen over Hogwarts School of witch craft and wizardry. The shadows swallowing the landscape and painting it in shades of black grey and blue.

Candles burn causing the large glass windows to glow as the first years finish their sorting and the feast begins. All people naive to the emerald green eyes watching from one of the large windows.

Ariana Potter gazed forlornly at the raven haired male laughing with his friends. She searched for him for so long, so determinedly that this sudden fear of approaching him seemed silly. Yet she could not deny that it was there, choking her every time she thought of it.

With a heavy sigh, the young woman turned and began to focus within herself; a single form entering her mind.

Soft feathers sprouted from her skin as the young woman shrunk, golden red hair receding as green eyes turn gold. Within moments a falcon took flight from where the girl once stood.

Ariana mentally smiled as she relished the wind rustling her feathers. Twisting in the air she fell into a steep dive, laughing inside from the rush of adrenaline as the earth came rushing to meet her. At the last second she pulled up and landed gently in the grass next to the west wall of the castle. Nothing took away her worries like flying, it was times like these she was grateful for her changeling blood.

Within moment she was once again a 5'11, lean built and pale skinned girl with a straight nose, hip length hair and wide eyes.

Ariana faces the wall and pulls out her wand, ebony with basilisk fang core, tapping a soft rhythm. The bricks writhed and moved until nothing was left but a large Oak door.

The Changeling entered and whispered an illumination charm causing the room to light up.

"I saw him again nyx."

The girl muttered to the black cat lounging on the old cot in the back of the room.

"Who Ariana?"

The girl sighed and stripped, the cat waiting patiently for an answer.

"My twin."

Nyx nodded and curled up to sleep once more. Ariana finished changing and crawled under the blankets of her bed. Staring around the room, she often wondered who used it. It had to be a student or teacher who left for summer because the entire time she had been here no one had entered.

"We'll have to move tomorrow nyx."

The girl whispered, the cat cracked open an eye.

"I know, but tonight you must sleep, the day has been long and you need rest."

She smiled at her furry friend before snuggling down and letting the dark claim her.

"Petrificus totalis!"

Ariana's eyes flew open and the sound of an unknown voice. She tried to rise but realized she was unable to move.

''Oi! George who do you think this is?"

I shifted my eyes to the voice and took in a tall red headed lean built boy, his chocolate eyes glittering in merriment. I growled.

"Dunno Fred but she doesn't look happy"

Another moved from behind the first and I noticed they were twins. I snorted and tried to focus on breaking the charm. It wasn't working.

The one called George studied her as his brother bounced from foot to foot.

"What should we do Gred?"

The other cocked his head to the side then nodded to himself.

"Take her to Dumbledore of course, he should know about someone hiding in the castle."

Fred smiled wide.

"Of course brother, most excellent idea."

With that being said, the two darted out of the room as Ariana floated behind them, silently screaming in fury.

When they reached the large eagle statue that hid the stairwell to the headmaster's office, the boys muttered the password in unison and hurried up the stairs.

"Come in."

A slightly raspy voice answered before the boys could even knock so they opened the door with a flourish.

"Headmaster we..."

"Found this little bird sleeping..."

"In our Work room."

The twins explained, each finishing the other's sentence. Albus Dumbledore peered at the captive over his glasses, a knowing twinkle glittering in his eyes.

"I was wondering when I would see you." He muttered with a smile as he looked back at the twins.

"It's alright boys, you may release her. I know who she is."

Ariana suddenly fell to the floor with a loud 'oof' but quickly stood and faced the Headmaster, fear wiggled in her belly at the thought of how much trouble she could possibly be in.

The headmaster continued to stare at her for a moment, his eyes still twinkling.

"Mr.'s weasley will you etch Harry Potter for me?"

The redheads looked confused but nodded anyway and disappeared leaving the girl and the old man alone.

"You know..."

Ariana looked just as the man began talking.

"If you're going to torment professor Snape by hiding in his bed or in his desk, you shouldn't snicker to yourself so loudly."

The girl merely grinned as she shifted her weight from one foot to the other.

"Yeah well even you have to admit it was hilarious."

Dumbledore went to answer but was interrupted by a knock at the door.

"Do come in harry, Mr.'s weasley"

Ariana's breath caught as the raven haired boy stepped into the room, His soft green eyes taking in her appearance before turning to the headmaster. She was so happy to finally be seeing him, to be standing in the same room with him. After all she had been looking for him since she was 10.

"You sent for me Professor?

Dumbledore Nodded and gestured to the young woman who still had not taken her eyes of the young man.

"I want you to meet someone Harry."

Harry turned and with a gentle smile offered his hand.

"I'm harry potter."

She smiled weakly and hesitantly took his hand.

"Ariana."

Dumbledore watch the exchange with a gentle smile before dropping the bomb.

"She's your sister Harry."
