Prologue

Harry felt like he could cry with joy. Don't get him wrong, he was sad for all those that were lost, but at the same time the war was finally over. Only, he couldn't rest yet, now it was time to disappear.

Many would be confused by the choice, but Harry had long since opened his eyes to the truth of the Wizardry World. And what a long list of truths it was, so long that he wasn't even sure where to begin.

He supposed it all started in the summer after fifth year. The day had been so hot that even he had not been told to go outside, but the house was clean and there was nothing to do. Or he had thought, until Aunt Petunia had told him to clean the stuffy attic.

It was while he was up there that he made the biggest discovery of his life. His mother was not an Evans by blood, but don't get the wrong idea, she also wasn't adopted. Although it did explain why Aunt Petunia had hated her so much. Well, aside from the magic, that is. Lily was only Petunia's half-sister. There was a paternity test that proved that Robert Evans; his 'Grandfather' in fact wasn't his 'Grandfather', and some of his Grandmother's old diaries. There were also some old photos of his mother's family as she grew up.

It turned out that while on a trip in Italy his Grandma; Rose Evans, had met a young man at a bar. It was an accident caused by her having too much to drink, but one thing had led to another and the final result being his mother Lily.

Apparently, his Grandma had run straight to his Grandfather when she found out, crying and apologising. At first he was hurt, but by the time Lily was born, he had come to accept the facts and treated Lily as if she were his own. Something Petunia apparently could never accept when she had accidently found out, and it only got worse when they had found out about Lily's magic.

There was even his real Grandfathers name – Renato Sinclair. Nothing else about him though. Still, it was an interesting fact to know, but not something he was overly excited about. After all, if all his other grandparents were dead, what was the chance that he was still alive? Knowing his luck, none at all. Still, it was a nice fact to know and explained a little more about why Aunt Petunia hated him.

He had snuck the test, diaries and all the photos he could find to his room and hid them under the floorboards. It was not as though his Aunt Petunia or any other in the family would miss them.

Then he had spent every moment he could reading through it all, looking at the photos and thinking. And somehow it was as though a crack had been made in the lenses over his eyes and he could see things a little more clearly.

Then, as sixth year went by, he started seeing more things and making plans because of it. And gradually, more and more cracks appeared in those lenses, until one day, they just fell out and everything was clear as day.

He realised that while Dumbledore wasn't bad, he was too old and tired. He missed things or didn't see how he could have done things better. He did know that Dumbledore had cared though, in his own way. He realised that first year was a test that went wrong, but ended well, while the other years were truly accidents. He also realised that Ron wasn't truly his friend, he wanted fame, money and attention he could get by knowing Harry. Forth year and the first task had proven that and he never should have welcomed him back. And while Hermione was a friend… she was also overbearing, and in the end, she would always side with Ron out of love. Not that he understood how that worked, he couldn't help but feel that Hermione could do better. Then there was Ginny. He really was the bad guy there. He used her as both a shield and as something to help forget other things when he needed to relax during sixth year. It was also a large part of why he never did more than kissing and holding hands. Plus, it was expected that he be with her by everyone and he just couldn't deal with them telling him to ask her out already.

But perhaps the strangest of all was how he had slowly become closer to the Twins, Neville, Luna and of all people Draco Malfoy and Blaise Zabini. The latter two, he had become close to in secret. He got close to both of them after that time he had found Draco pacing in the bathroom. It had almost ended in a big fight, but somehow it was like the fuse was dipped in water before it had even started to burn. Harry had said that he didn't care what he was doing in that bathroom and that most likely; very much like himself, he just wanted somewhere quiet to think, and it just sort of grew from there. Blaise came in later looking for Draco and as they say, the rest was history.

So he planned and somehow they became a part of his plans too. He knew of Draco's mission and Snape's vow from the start. He made Draco calmer by pointing out that Dumbledore was already dying, and no doubt already knew of his mission, but they had to make things look convincing. And so Draco became his spy in the dark, while Blaise was his spy for the neutrals and Draco's support. They couldn't do much, but it was still something.

He gave the Twins more money for their store to help them make more items for people to survive the war. If Blaise knew for sure that someone was neutral, then they were guided to the twins with a special passcode, that always change for each person. They would be given things like instant darkness powder, fake wands, warding bracelets and other such items that might help them to either fight or escape the enemy. They had to do things a little differently with the light side because otherwise they might have drawn too many eyes and paranoid thoughts to themselves. And they all knew on some level that Harry had something planned and didn't want others to know.

He made Dobby and Winky his house elfs and had them pass on any of his secret letters as well as check his food and personal items for him. He had the Goblins start the process to change his name at the end of the war and learnt about his other vaults he could access once he turned seventeen. He also told them about Voldemort's Horcruxes and paid them to find out if there was one in any of the vaults and which vault. When it was made clear there was one, the cup in the Lestrange's vault, he knew he couldn't ask them to destroy it and they also couldn't just give it to him. So instead he made plans with them to knowingly break into the bank sometime in the future with the full intention of paying for any damage. After all, the goblins had to remain neutral because of their agreement with the wizards. Oh, Harry knew as much, that he couldn't just walk in, it had to be hard or the goblins pride would be wounded more than it was already going to be. It is also why he knew that it would cost him a lot after it was all done. So it had to look convincing and the goblins had told him as much, but at least they wouldn't just steal all his money and completely block him from the bank forever.

But now the war was over and most of his plans were already set, with a few differences. He had to take his godson Teddy Lupin with him now. Amongst the many deaths in the war; both before and during the final battle, was the last of Teddy's family.

Ted died on the run, Andromeda was killed in a surprise raid after Teddy's birth, Dolohov killed Remus in the battle and Tonks was killed by Bellatrix. Luckily Teddy had been left in the care of Winky. So Harry knew he could call her to him once he reached the bank.

Others loses that were the most painful were Dobby, Colin Creevey, Severus Snape, Hermione Granger, and Ron and Ginny Weasley. Although it was a near thing with Ron. Fred tried to get between him and the curse the death eater had fired, but he was just a few short seconds too slow.

Tired and dirty, Harry had managed to convince the others that he just needed some time alone. He quietly walked down the grounds of Hogwarts and out the front gates, before he apparated to just out front of Gringotts Bank.

When he walked through the doors of the bank, he could see that there was still some damage, but that most of it had already been repaired. He was quick to make his way to the teller who seemed to be expecting him and quickly took him to his account manager Sharpshooter. Before he sat down though he called Winky to him, who was quick to pass him Teddy and then readjusted the black shoulder bag she had on her. As soon as he held him, Teddy's hair turned from turquoise to black and his eyes turned from a soft brown to emerald green matching Harry's. He then sat down with Teddy in his arms, while Winky waited quietly in the corner.

"Good to see you again Mister Potter or should I say Sinclair?" Sharpshooter asked.

"Sinclair will be fine Sharpshooter and I'm glad to see you too. We will have to go through with those quick alterations to the plans, after all though." Harry said as he looked down at the now lightly sleeping baby, "Teddy here is now an orphan like myself," he spoke softly with deep sorrow.

"Right away then. I had the paper and potion here just in case," he pulled a draw open and pulled out a large pile of papers and a potion. "I assume you know where you need to sign and how to finish the potion." He finished as he placed them in front of Harry himself.

"Yes, thank you Sharpshooter." He read through the papers as quickly as possible, passing Teddy back to Winky while he signed. The first accepted all of his family titles and vaults, ext. The second transferred all money, assets, and houses he now owned from other vaults, such as the Blacks, to the Potters. The third changed the Potter families name and magic to Sinclair. So that if anyone; Ministry or rogue Death Eater were to look for anything to do with the Potter family, they wouldn't find a thing and likely think he was dead. Harry had thought about changing his last name to Peverell, Black, or Evans, but they can all be connected to him and the name Potter. Whereas no one in the Wizardy World would know the last name Sinclair. The forth adopted Teddy as his son in both worlds. Although once he gave Teddy the potion, the papers would change to say that Teddy was his real son. The next two papers changed their names.

For himself, he chose Jameson Renato "Jamie" Sinclair – Jameson for his father and Renato for his real Grandfather. And for Teddy he chose Theodore Remus "Teddy" Sinclair because he didn't want to change it too much for Teddy and Theodore is apparently another version of Ted and thereby connected to Edward.

Then there were new birth certificates and papers to give them dual citizenship between Italy and Britain. Papers to make Teddy his heir and a will if something happened to him, and a few other things, including the bill for the break in and for the dragon to be brought back.

Finally, there was the potion. He made a small cut on his thumb and allowed three drops to fall into the potion. Winky came forward with Teddy and he gently fed the potion to him. Slowly, so that none of it was wasted as he wrapped the child in his magic. There was a sharp spike of magic around him and then it was over. Technically, he was still Remus's son, but any test would prove that he was Harry's. There were also small changes now to his nose and cheeks shapes, not that it would matter with Teddy's ability as he gained more control.

The Wizardry World was strange like that. There was no way to do a blood test and trace family trees back, but they had potions that with a bit of blood would allow you to make any child you adopted, yours in blood. Probably so that Muggleborns couldn't prove they came from a long line of squibs and might have a closer claim to a families' money. Harry had asked out of curiosity, apparently the Black family tree was a secret family magic.

Finally, he was done. He passed it all back to Sharpshooter. "Thank you Sharpshooter."

"You are welcome Mister Sinclair. And here is your key and family rings. As you put them on, they will all merge into one, finishing the merging you started with the papers." He explained as he passed a wooden box to Harry – now Jamie.

There was the Potter ring and the Black ring which he expected. What he didn't expect was the Lupin, Prince, Tonks, Lestrange, Crouch, Pettigrew, or Gaunt. Some of them, being from lesser families, were simpler than others. He looked up at Sharpshooter in question, although he had a possible idea about the Pettigrew ring.

"Before the first war got really heated up, your father's friends Black, Lupin and Pettigrew made you their heir. It is unknown why Pettigrew never changed it after he turned traitor. Lupin's would have gone to his son had you not just adopted him. Same for Tonks. Prince is Snape's mother's maiden name and family magic, he made you his heir after the first war. Lestrange and Crouch are distantly related to you, and Gaunt is by right of conquest," He explained.

'Yeah, that definitely made my earlier thought plausible,' Jamie thought to himself, 'Pettigrew likely made me his heir when he was on their side and then kept it that way to solidify his place with my parents. Kept them thinking he was on their side, but because his betrayal was covered up with his death and Sirius's conviction, he couldn't exactly pop in and change it. And he certainly couldn't after he was found out,' he thought as he snorted under his breath in amusement.

Jamie looked down at the rings again and then back up at Sharpshooter, "I see… Thank you." Looking down at the rings again – most were gold or silver, but some like Tonks, were bronze in colour, signifying the families standing – he slowly put them on and watched in fascination as they all merged into one twisted gold and silver ring. He then picked up the key and put it in his pocket for now, later he would put it on the enchanted wallet he had like a keychain. The wallet itself was a special Gringotts wallet that allowed the owner to withdraw money of any currency, directly from your vault without being anywhere near the bank, and from anywhere in the world. As a safety feature it was also linked to that wizard's magical signature so that no one else could use it.

Finally, they were ready to leave for their new home. All of his items that weren't in Hermione's beaded bag; which he had shrunken in his pocket, were in the black shoulder bag that Winky had. It had the same undetectable extension charm as Hermione's bag and held everything he owned and then some.

Tiredly standing up, he accepted the international portkey from Sharpshooter, it was a long strip of rope, and walked over to Winky. "Thank you Sharpshooter," Checking that they were all touching it, he said the password to activate it.

"Freedom."

AN: Wow… this Prologue is longer than any other I have written. I somehow find that really funny when this story is currently less planned out than any other story of mine. Still, I hope you liked the intro. I know I skipped much, but this story isn't about the Hogwarts years, and since most of the school years and war didn't change I figured you can build your own idea with the small differences. The way I see it, it was mostly the same as the books.

Edit: Small changes made after ArzanianJoy pointed out two things to me. Also edited with ArzanJoy's help.
