A/N: Multiple characters in this book are not portrayed the same as in the Harry Potter series by JK Rowling.

This story is set in Harry's sixth year, though many events happening in years prior have not happened, for example Sirius Black is still alive.

Also my spelling, punctuation and grammar is not exactly perfect, so please don't be too harsh.

"We all have good and bad inside of us. It's what side we choose to follow that defines who we really are." - JK Rowling, Harry Potter and the Order of the Phoenix

"Harry Potter! What have you done!" Dumbledore shouted as he slammed his fist onto the wooden desk infront of him. Harry kept his gaze down, instead choosing to watch as the items on the table jumped from their places. He felt strangely ashamed as he fell victim to one of Dumbledore's rages. He wondered if this is what others his age felt when their parents told them off. Of course Dumbledore wasn't his father, but except from his godfather Sirius Black, Dumbledore was the closest thing he had to a parental figure.

Sirius sat in the chair next to Harry, his hand placed on Harrys shoulder as a form of support.

"Now now Dumbledore, don't take this out on the boy, he didn't know." Sirius said, defending Harry, as he lent forward in his chair. "It was only 6 years ago that he found out about the existence of wizards, he can not be expected to know everything." Dumbledore took a deep breathe, feeling the adrenaline and anger still pulsing through his body, he knew he shouldn't of handed Harry over to his Aunt Petunia and her vulgar family. Harry would of been better off growing up in a wizarding family, he needed to know as much as he could about the wizarding world if he had a chance at defeating Lord Voldemort and his lackeys.

"Walden MacNair is arguably one of the most powerful and evil wizards in existence." Dumbledore began explaining, feeling slightly guilty to his overreaction. "Him being in Azkaban is far from benefiting us." Harry stared towards the old wizard confused.

"Why not? He's a deatheater, he tried to attack me. What was I expected to do?" Harry asked and turned his head from Dumbledore to Sirius and back again.

Dumbledore momentarily ignored the question as he stood up from his seat. He turned towards the back wall of his office which laid in the depth of Hogwarts School of Witchcraft and Wizardry, and ran his finger along one of many shelves of books. Most were covered in thick layers of dust, untouched for years, some even longer, saved incase Dumbledore one day decided he needed one. On the whole of the middle shelf which held atleast 40 books, only one lacked the dust covering. He pulled the book from its place and ran his hand along the leather cover. It wasn't the normal book size, instead it was square and resembled a large scrapbook. The leather of the book was black, and slightly worn from how long it had been owned, but also how many times he had needed it. On the front cover engraved in silver text said the words: 'The MacNair Family'.

"The MacNair family is one of the oldest wizarding families known." Dumbledore placed the book on the desk infront of Harry and opened it to the very first page, where there was a family tree resembling the one of the Black family at Grimauld place, minus the pictures. "The family consists almost completely of pureblood witches and wizards."

"Most deatheaters come from pureblood families though, so how does that make Walden MacNair so much different to others?" Harry asked.

"Most people turn evil due to their pasts and experiences, occasionally due to circumstance. This family however are simply pure evil, but most importantly they have incredible magical abilities that many are envious of. Most wizards wouldn't be able to escape Azkaban, but Walden would easily be able to, and he wouldn't just allow himself to escape, he would completely empty the cells." Sirius shifted awkardly in his chair, remembering his own terrifying escape from Azkaban, and the people who were hidden in the hundreds of cells. The complete opposite reaction of the guilt that filled Harry. He one day wished to be an Auror, to fill the Azkaban cells of those who deserved it, yet here he was facing the fact that he was arguably to blame for a future mass break out. He didn't know the kinds of wizards that filled the cells, but one thing he did know was these were some of the most dangerous, and threatening wizards who were far from afraid to kill and torture.

"Their interest into the dark arts have been some what known about for many years, though the ministry lack proof, and only a fool of an Auror would actually go after him or other family members." Dumbledore reached across the desk and flicked through the pages of the book stopping at one. On the left page held a picture of Walden alone, and on the right was a picture of what Harry assumed to be his family, it was the picture of Walden which seemed to be cut out of the newspaper, probably the Daily Prophet, yet the other picture seemed almost brand new. Just looking at a picture of Walden caused chills to go down Harry's spine. He was the kind of man who could intimidate just about anyone. Harry could hardly believe that just under 48 hours ago he stood infront of the man. It had only been a year ago since Harry found himself fighting off the dementors to save not just himself but his older cousin Dudley, and he had only just found himself in the a similar situation against one of the most fearful wizards. Part of him hardly expected to be attacked again in the muggle world. It was a place where he was nobody, compared to being the 'chosen one' in the wizarding world, so part of him slightly convinced himself that nobody would bother with someone like him. He had however been keeping his guard up. After Voldemort's return 2 years ago he knew that he would constantly need to be alert of absolutely anything, that was why he instantly suspected MacNair to be a deatheater.

'He had been forced to accompany Dudley to town, his Aunt and Uncle were fearful incase any harm came to their 'little Duddykins' whose chances of falling victim to a wizarding attack due to association with Harry was reasonably high. They didn't live to close to the town they found themselves walking to, as they had recently moved. The Dursleys were very concerned about their reputation within their world of people, god forbid it be known they were related to a wizard like Harry. So they saw moving to a much remoter village to be the only choice. A village with a rather low population, where the majority were concerned only in their own business, rather than trying to stick their noses into their neighbours business.

It was when Harry and Dudley were walking through an abandoned field that the attack happened. It was very rare to see a car nearby, and it was when an expensive car with blacked out windows, stopped on the side of the single lane road that Harry became increasingly suspicious. His hand instantly flew to grab his wand, as he closely watched as a tall man dressed in black a black suit complete with a clock exited the car. Harry was the first to cast a spell, knocking the wand from the mans hand, though it wasn't long until Harry managed to find himself at the negative end of a few spells himself. He was no where near the same skill level in duelling as this mysterious man had. Part of him knew he was going to loose, and as he watched as the fat lump of lard known as he cousin attempted to run away, he could only hope he would be able to save the person who had bullied him for all these years. It was just when Harry was at his weakest that he suddenly found himself surrounded by the white smoke that he appeared to see more often then not, the white smoke he managed to associate to the savers…..the aurors. He sat down on the ground, paying no attention to the arrest which took place infront of him, he payed no attention to the no less than a dozen aurors out magic this singular man, and then paid no attention to the man willingly going to his future… prison.'

"They." Dumbledore pointed to the moving picture of he right page, "are the MacNair family. Atleast they are the closet relatives to Walden." Harry grabbed hold of the book, bringing it closer to his face. There was something about this family that managed to intrigue him.

"That of course is Walden." Sirius said, looking over Harrys shoulder at the book and pointing to the man in the centre of the picture. "The woman whose shoulder he is holding is his wife, Ava. She is the typical deatheater's wife, a kept woman, never working a day in her life. The assumption is that their marriage would of been arranged." The woman, Ava was sat on the chair, her head held high with pride, and not a single hint of a smile appeared on her face. It was obvious by her over the top gown she wore that she was definitely rich.

"The two older boys are twins, Edward and Isaac both 21. Isaac is engage to his school sweetheart, and the youngest boy is Jack he's 9, due to start Hogwarts when he turns 11, unlike his brothers who went to a much more exclusive school." The two eldest boys were the spitting image of their father, whereas the youngest boy had more of the feminine features of his mother. It wasn't any of those who managed to catch his attention, it was the other girl, sat beside her mother and her older brothers hand upon her shoulder. She looked so out of place in the what would of been perfect picture of such a cold family. She shone with such a unique look compared to her family members, and bought a bit of warmth to the picture.

"Whose the other girl?" Harry curiously asked. He expected Sirius to reply, but upon hearing no reply he turned his attention to Dumbledore. It was anything but rare that Harry saw the partly distressed, partly weak emotions that he saw upon Dumbledores face. Dumbledore placed his chin on his hand, and took a sigh.

"That is Caitlin MacNair. Or as everyone else knows her as: The Missing MacNair." Dumbledore explained barely above a whisper.

"Why?" Harry asked, he was now becoming confused to the reaction he received from both Dumbledore and Sirius, they were both people who would rarely find themselves lost for words.

"Caitlin MacNair was last seen in public when she was 6, that was 9 and a half years ago." Dumbledore took the book from Harry's hand and turned the page over, before handing it back. Harry looked at the newspaper clipping titled: '5 years on: where is the MacNair?'. Along side the article was a picture of her stood beside younger versions of her brother, she younger herself. It was obviously her, as she once again bought warmth to an otherwise cold picture.

"Why does it seem to be such a big deal?" Harry asked, flicking through the pages of the book, finding multiple article on Caitlin, but also the family as a whole. He knew Dumbledore must of kept them for more than just reading material, and couldn't help but wonder why.

"Because everyone knows she is the key to taking down the deatheater's and Lord Voldemort himself." Sirius answered.
