A/N: I wasn't going to post a new story until I finish the other two stories I'm working on, but I couldn't help it!

I'm so excited for this story and I've had the idea stuck in my head for the longest time! I won't be able to update for a while, since other stories are higher on my priority list, but I will update as often as possible.

Please note that the OC is 18 years old while Sirius is around 36 in the 5th book, an age difference of 18 years. However, I obviously threw this fact out the window.

I have a feeling this story will be slightly crazy, but bear with me. Reviews would be awesome!

It was a rather bright sunny day as the young girl and her caretaker took a walk through Grimmauld Place. "…seven, eight, nine, ten, eleven, twelve…." The small 5 year old girl counted the house numbers happily as she walked next to her caretaker, Nana.

"No, look here," Nana pointed to the house next to eleven. "See? Next is house number thirteen. They skipped the number twelve all together."

The young girl looked up at Nana and back at the house. "No…" She pointed up to house number twelve. "Can't you see it Nana? It's right there."

"Come now silly Arabella. You're just letting your imagination run wild again."

"Am not, it's right there!"

"Come on Arabella, your father is waiting for you at home."

Ever since I could remember, I could see things others couldn't.

I could hear things others couldn't.

I even talked to things others couldn't.

No one else could.

Every day I had to pretend.

I had to pretend that the world I could see didn't exist.

Chapter One

In Which She Drew a Picture of a Man

The eighteen year old woman walked leisurely along the sidewalk. Her white floral print dress swirled about her knees as she went along and her waist-length dark brown hair moved along with the slight breeze. It was a sunny summer day, very hot and humid, but she took her time getting to wherever it was she needed to go. She eventually arrived at Grimmauld Place, an area she spent quite a bit of time in since she was a child. As she passed the empty playground, she began to count the house numbers as she always did. One, two, three, four, five, six, seven, eight, nine, ten, eleven…

"Arabella! Arabella!" A high pitched feminine voice shouted out. The young woman, whose name was Arabella, looked up ahead to see a small figure zooming toward her. Arabella held out her hand and the small figure landed on it; the figure was a little fairy with golden hair and eyes. The little white dress she wore was decorated with small golden leaves. "How are you, Linore?" Arabella greeted the little fairy.

"Wonderful! But we have more important things to talk about! Humans are living in the House Arabella!"

"The House?"

"Yes! They're living in House Number 12!" Arabella then looked up at the house on her left, Number 12 Grimmauld Place. It was the number one mystery of her childhood that still puzzled her to this day. How could it be that no one else could see the house? The house wasn't a magical creature, like a fairy. There was no way for it to hide itself; it simply wasn't magical, was it? Besides, how could anyone live there, if no one could see it?

"Are you sure there are people living there?" Arabella asked a bit skeptical of the little fairy.

"Linore is correct, for once." A small masculine voice said, startling Arabella.

"Tamesis!" She peered down at her right shoulder. "I didn't see you."

"Obviously." He rolled his eyes. Unlike Linore, Tamesis' attire was darker: ripped black wife beater, black jeans, dark grey skin, and decorative black thorns. His eyes and hair were equally as dark, somewhat reflecting his personality. He picked at his clear wings absentmindedly before continuing. "A few days ago wizards moved into the House."

"Wizards!" That explained where the magic came from that kept the House hidden from others. How could she not think of wizards before? "You two must tell me all about them!"

"They aren't that exciting…" Tamesis mumbled, while Linore seemed rather excited to tell Arabella what she knew. Arabella carried the two fairies to a bench, which was situated in a position so that it was facing the house. Sitting down on the bench, she then moved the two fairies to settle in her lap. "So…" She started and Linore flew up to speak. "The wizards are like normal humans, except they use magic a lot for everything."

"It's not that exciting. All they seem to do is cook and clean," Tamesis interjected.

"Tell me what they look like. Do they wear strange robes and pointy looking hats?" Arabella asked.

"Some do, some don't. Most of them just where normal human clothes all the time!"

"Only a certain number of wizards live in the house itself." Tamesis informed her. "There are others that come and go from time to time."

"I see…"

"Oh, but Arabella! There is one wizard that looks so mysteriously handsome!" Linore swooned at the mere thought of him.

Arabella took out a sketchbook and a pencil from her shoulder bag. "Go on!" She laughed. "Tell me what he looked like."

"He has shoulder length hair as dark as the midnight sky on a moonless night and his eyes are a dark silver…" Linore started dreamily.

"His hair looks dull and he may have some split ends. His eyes aren't that amazing; they're more like a stone gray." Tamesis chimed in.

"He's tall and lean and his clothing is refined…" Linore continued.

"He's tall and skinny. It looks as if he hasn't seen the light of day, no matter how refined his clothes are…" Tamesis added.

"Will you stop interrupting me Tamesis!" Linore shrilled, fed up with his random insertions.

"You need to stop over exaggerating his looks. In my opinion he's a bit above average, but you make it seem like he's some Greek God."

"Well, how do you know he isn't one?"

"He isn't because that makes no bloody sense! Listen to yourself! You sound like some love sick child."

"I do not!" The female fairy whined.

"I finished you two." Arabella announced, breaking up their spew. She held up her sketchbook so she could see it from afar.

The two fairies flew to see the sketch of the mystery man. "It looks just like him." They said together. The girl sighed and admired the sketch before her. In less than a millisecond, she wanted to know more about this man; his likes, dislikes, hopes, fears. It was a strange feeling, seeing that she has never even seen this man before.

Linore noticed that she was in deep thought. "What's wrong Arabella?"

"Nothing…it's just that…it's just that I wish I could meet him."

"You can silly! You have us remember?" Linore exclaimed and pointed to herself and Tamesis.

"What do you mean?"

"What she means is that our fairy magic is stronger than wizard magic." Tamesis explained. "Any sort of magic that keeps you out of the house, we might be able to overpower. Fairies existed long before wizards, so our magic tends to be more powerful most of the time."

"Oh…but I have a piano lesson today with Mr. Walters." Arabella sighed and packed her things away. "I really must be going."

"Come back tomorrow then! We can visit him tomorrow!"

"I don't think that's a good idea Linore…"

"But don't you want to meet him?"

"Yes…" She confessed softly, but continued down Grimmauld Place, without another word to the two fairies. She wanted to see the man, but she was unsure. Fear held her back, the fear of not knowing anything about this man, except that he was a wizard with black hair and grey eyes. With her eyes focused on the ground, she walked in deep thought and just as she was about to leave Grimmauld Place, she ran into someone. "A number of things clattered to the ground. "I'm so sorry!" Arabella began scrambling to pick up the boxes the stranger dropped.

"It's nothing to worry about," the man reassured her as he picked up a box. She noticed when she looked up that the man wore worn out tan dress pants and a simple white shirt. He didn't look like he was from around this neighborhood, since his clothes weren't exactly upper middle class attire.

"Would you like help carrying these?" She offered.

"No thank you, it's not necessary."

"I insist." She had already began walking in the direction the man was headed. "My name is Arabella Roland. I live just a few minutes from here at Radiance Court. Are you new around here?"

"I'm just passing through…you shouldn't give too much information about yourself to strangers. You'll get yourself into trouble that way."

"Oh…" She looked away, blushing from her obvious naivety.

The man noticed this and smiled kindly. "My name is Remus Lupin. I suggest you be more careful in the future, Miss Roland."

Arabella was relieved he introduced himself as well; she didn't feel as foolish anymore. "So…what are you doing with these boxes?"

"I'm making a delivery for a friend."

"Oh! The things in the boxes aren't fragile are they?" She asked in fear that they may have broken.

"No, but they are important." They walked together in silence for a moment, before Lupin spoke again. "I think I can take it from here. The rest of the way is a bit far out of your way and I don't want to waste anymore of your time…"

Arabella set the box she was carrying on top of the ones he carried. "It wasn't troublesome at all! I'm glad I was able to help you. Well, until we meet again I guess…" She waved goodbye, with a smile on her face, and turned around to head home. That's when she remembered she had a piano lesson to attend to and began to run. She didn't notice that she and Mr. Lupin had stopped in front of house number 12 of Grimmauld Place.

Sirius Black stood by the window and watched as the brown haired girl ran off again. He had taken a habit to waiting by the window around 3 o'clock in the afternoon almost every day to see her walk by. He found it strange that he saw her walking with Remus. From all the times he had seen her, she was always walking by herself.

Sirius sighed; he couldn't deny the fact that he had been watching this girl walk past the house around 3 o'clock every day since he'd moved back in. He also couldn't deny the fact that this made him seem like a creeper, but he had a good reason as to why he was intrigued with this girl. The first day he saw her; she had stopped and looked up at the house, as though she could see it. She stood there for a while, and for a moment he thought she could see him gazing down at her, on the street below. He found her behavior, from that day on, to be rather odd for a muggle. Other than looking at the house, she would sometimes talk and laugh to herself, like she did earlier today. What a strange girl…

"Sirius!" Remus called out and Sirius went downstairs to help his friend. "About time." Remus handed him a couple boxes to carry. "What were you doing up there?" Remus asked.

"Nothing." Sirius murmured. "Who was that?"

"Who?"

"The girl that was with you."

"Oh, you saw her. I'm sure she's just an average muggle girl. She said she lived in Radiance Court."

"She told you where she lived?" Sirius repeated, unsure if he heard his friend correctly.

"Yes, she was a bit naïve, but a very kind girl none the less, or at least from what I could tell. She even told me her name."

"Her name?"

"Arabella Roland." He told Sirius offhandedly.

"Arabella." Sirius repeated the name; it seemed to roll off his tongue with ease. Remus went to put the boxes away and Sirius followed. Arabella, now he knew her name and, for some odd reason, knowing this made him all the more eager to watch her walking past his window again.
