AN: A new idea from me and thus a new story. Not much to say for now, besides enjoy the chapter and stay tuned. If everything goes well I will update again within the week.

Disclaimer: I own nothing as sad as it is.

It is said that the fluttering of a butterflies' wings can cause tsunamis. This is the so-called 'Butterfly Effect' and essentially it means that the smallest action can have the biggest of consequences. For example, the unexpected arrival of one person at the wrong place at the wrong time, can not only change two lives, but in the end the lives of many thousand people, a prophecy and in the end destiny itself. Why I tell you this, you may ask. Well, because sometimes a simple stroke of luck can change everything.

But I best explain this little theory on an example. Let´s see …

How? That was probably the most asked question on 31st October in 1981.

The first to ask this question was James Potter.

For the Potters Halloween had been rather calm, since they were in hiding and didn´t expect any visitors. Both had used most of the day to play with their one year old son. Harry James Potter. For them he was a miracle and like all parents they were incredibly proud of their little bundle of joy. For example, little Harry had ridden his child-broom, a gift from his godfather Sirius Black, for a couple of minutes today and immediately James had seen the best Seeker and professional Quiditch player for the next century. However, when Harry had picked up one of his picture books earlier one, Lily had seen a top student and Head Boy. I don´t have to mention that they had very different hopes for their child, have I?

Now little Harry was upstairs in his crib, the proud parents had brought him up there and set him to sleep an hour ago. They had spent the last hour cuddled together on the couch; they hadn't said much, they had just enjoyed each other's company and the brief time of peace in the ever waging war. Right now Lily was upstairs to get ready for bed herself and James remained on the couch for some more minutes listening to the Wizard Wireless Radio. He was listening to the news, which mostly consisted of more reports of missing persons or even some deaths. Today however, seemed to be a good day, as not one mention was made. In times like these, no news where good news. Pondering this line of thoughts James really hoped that someone (Dumbledore) would finally set an end to this senseless war and put Voldemort in his place. But he wasn´t delusional, he knew it would take a miracle to end this war.

Oh, how right he was.

Just when James decided to retire for the night, he felt a very uncomfortable feeling. This feeling could only mean one thing: Someone had breached their wards!

Immediately he sprang into action, he and Lily had prepared for something like this since Dumbledore had told them that Voldemort was after their son. There was no hesitation, no fear in him, he knew he wouldn´t survive the night, but if he could just buy his family a minute or more, it would be enough.

He warded the front door with the most powerful and nasty wards he knew, some of them were considered Dark Magic, but to protect his family he would do what was necessary. When he had finished this task, he made it halfway up the stairs and waited. Hidden in the shadows in the narrow staircase, he really wished he had his Invisibility Cloak right now, which would make for a good surprise attack. However, he had given it to Dumbledore days prior, so he had to work with what he had. His skills.

It didn´t take long before, with a thunderous crack that shook the whole house, the front door was blown open. James didn´t even flinch. He knew he had only one chance for this, so he used every skill he had acquired in his time as a Marauder; he hid in the shadows, concealed his magic and even held his breath. No movement, no sound, shortly nothing gave away his position. He waited till the last possible second, when the Dark Lord was just a step in front of him, till he wordlessly released the strongest Explosion Spell he knew. And nearly, nearly he succeeded.

The spell was too close for Voldemort to completely block it; however he managed to set up a shield in the last possible second, which took the brunt of the explosion. Still he was thrown back into a wall and the breath was knocked out of him. Add to that the fact that most of his skin and his robes were burned and you can imagine why he was furious right now. How dare this filthy man hurt the great Lord Voldemort!? With glee he spoke the deadly words and sent forth the green spell that would end James Potter´s life. Avada Kedarva.

The moment Voldemort threw up a shield, James knew he had lost. Not that it came surprising. When the Killing Curse came, he knew he couldn´t dodge in this enclosed area. No shield he could conjure would stop the spell and so he took it like the proud Gryffindor he was. Head on.

They say in your last moments you see your whole life run before your eyes, for James there was nothing like this. All he saw where his friends and family. Moony, a friend he hoped he could one day cure, a problem that would stay unsolved for now. Padfoot, his friend and brother in heart, who would take care of Lily and Harry now, he hoped. Wormtail, who he had taken under his wing in his first days at Hogwarts, now he needed to fly on his own. His parents, who he would meet again every second now. And finally his wife and son.

James Potter was a proud man, a Marauder, Head Boy, one of the best in class and so on. But in his last moment he begged. But not for himself. He simply begged that his wife would achieve whatever she tried up there and his son would be safe. He was aware that they hadn´t taken the emergency Portkey, for whatever reason. And he knew his wife, so she probably had some kind of backup plan. Hopefully it worked.

One question remained however: How had Voldemort found them? Before he could ponder this anymore the question was lost and the Killing Curse upon him and only one thing remained to do.

He just begged and prayed to every deity who was willing to listen, that his son would be safe and happy.

And so shall it be.

To have a voice in his head would normally have startled James, but not right now. All that mattered were his son and wife. And a second later he didn´t care anymore. For James Ignotus Potter died while protecting his wife and son against Lord Voldemort. Given the chance he would do it all over again.

The second person to ask how was Lily Potter.

As in: How did it come to this?

Sadly she never got an answer to this.

When the wards were broken, Lily went to Harry´s room immediately. James had made sure to pound the plan into her head. If something goes wrong, take Harry and use the emergency Portkey, which was placed over Harry´s crib and would bring us directly to Dumbledore´s office, and get out of there.

Unfortunately the Portkey didn´t work.

Lily Potter wasn´t one to curse often, but in this case … Damn. Anti-Portkey Ward probably set up by the intruder. However, Lily was also called the most intelligent witch of her age. Time to proof it.

While James had trained himself in every way possible, should there ever be an attack on them, which was highly likely, since Voldemort targeted Harry, because of a stupid prophecy … Back on track, while James had trained like mad, she had put all her efforts into research. She had delved deeper into the depths of magic than Dumbledore himself. And finally she had found something.

In a book that belonged to the Potters, so old that it nearly broke into dust when she touched it and in a language that took her three weeks to translate, she found the unthinkable. Lost Magic. A magic so old, its existence forgotten by everyone, well except of her now.

The Lost Magic: Key of Destiny.

There was a little description to the ritual, but it was truly astounding what she had found there and if this worked out she could defeat Voldemort and this damn Prophecy in one stroke. But the ritual took a life in exchange.

Suddenly she felt a rumble in the house, probably from some kind of explosion. Well, better work fast now. She had everything ready as it was. Days ago she had finished the Keychain that was required for the ritual and now she placed it on a string and with that on Harry. When she did so, she noticed that Harry had woken up, probably from the explosion. She looked her son into the eyes and steeled her resolve. For Harry.

The incantation to go with the ritual was fairly easy and was quickly spoken, while a second explosion shook the house. Shortly after she finished her incantation she saw a green light under the door. Now she was all alone. But she would see him again very soon. For all that was left for the ritual, was for her to give up her life by her own free will. For Harry.

When the door opened and Voldemort stepped into the room, she barely took notice of him. And all she did in response to his presence was placing her body firmly in front of her son´s crib. She had nothing to say to a dead man.

Other than that she was enclosed in her thoughts. Hopefully Snape manages to get away with what he has done, because after all he has once been her friend and for now she had forgiven him; she didn´t want to die with a grudge against him. Next on her list was Peter, but in this case she really hoped the rat got punished in some form, after all he had betrayed them and endangered Harry. Hopefully Sirius would keep his temper in check, no need for him to go after Peter; he now had to look after Harry! Speaking of Harry, she of course saw the wand movement the snake made and heard what he said (Avada Kedarva), but she didn´t really care. She turned around one last time and looked at her baby son, who she would never see grow up, but that was the only way and to protect her son she would die one-hundred times over. For Harry …

The last line of the incantation came to her mind and as her last thought she recited it in her head once more: From sacrifice light will be born and door will open, fear not for the Key will arrive.

And so Lily Evelin Potter followed her husband in the next great adventure, thus setting loose a little ripple. A ripple that would change destiny, hopefully.

The third person to ask was the great and dark Lord Voldemort in person.

Everything had gone fine so far. The world was in terror, the Ministry in shambles and even Dumbledore and his little group couldn´t do much against him. But just when everything seems right, he hears about this Prophecy from one of his best men, not that this was a true Prophecy anyway. But he was a cautious man, so better safe than sorry.

After Voldemort had made sure that the Prophecy was about one Harry James Potter, it was just a question of hunting them down. It just happened that one of Voldemort´s followers, a traitor by all means, became their Secret Keeper … this was just too easy. Well there came the time for a visit.

Of course Voldemort had to admit, that James Potter had put up quite a good fight, by all means he even came close to injuring him, well closer than most. But in the end he met the same end as everyone else, who dared to oppose Voldemort, met.

His wife, this mudblood, of course he had been asked to spare her, but when she stubbornly refused to step aside, or maybe she had been frozen in fear but who cares, there hadn´t been another way than to kill her too.

He came for one and now he would kill three, not that it matters much to Lord Voldemort.

He savored the feeling of power when Lily Potter´s body hit the ground. That was true power, this was the reason he was born, to kill this was his reason to exist. And now he would take care of this little nuisance.

But looking down at the baby, he nearly had to laugh. After all hundreds of people had stood against him and in the end they had died and he had lived. He had walked the road to immortality further than anyone else. He was so close to become a god in human disguise. And this Boy should have the power to defeat him? Ridiculous!

And now he would prove it! He would prove the world that his reign would be forever and there was nothing they could ever do about it. They would bow down to him soon enough. And all it would take was a simple movement of his wand and the well mesmerized words of the Killing Curse to end this nonsense once and for all.

But just when everything goes well, when he made the last step to everlasting power, just when the spell was complete and the green curse on its way, his world came crumbling down.

For in front of the tiny baby appeared a solid ball of … light?! How is this possible? It wasn´t supposed to be like this!

The light exploded outwards and in its place now stood another Boy. Blond spiky hair, sky-blue eyes and strange clothing. A completely normal boy, but Voldemort knew, deep down, that something had gone wrong.

And he was proven correct when the boy lifted one arm and the light reappeared. When it faded once again, the boy was holding a …Key? Either a very overlarge Key or a very strange sword. But what mattered was that somehow that Key reflected the Killing Curse. Voldemort knew that he couldn´t avoid or block, he was after all completely unprepared for this. For a moment he mused that this green light made a nice last sight for his victims, but then again he had nothing to fear. All he had to do was wait, till one of his loyal followers came to help him pick up the pieces. He was Lord Voldemort and he was immortal. And most importantly he was a patient man, he could and would wait.

But still one question remained: How was this possible?

With this in mind Voldemort was hit by his own Killing Curse and his soul ripped from his body, to wait for the right time to return …

Sirius Black was the last person to ask the question how on this tragic 31st October. His question was a simple: How could this happen?

*Sirius' POV*

I had come over to visit my (not-blood-related) brother and my sister-in-law and most importantly my godson … and what I find are the half caved in remains of their home. I was frantic and just took out my wand to banish or blast away every bit of rubble in his way. Just when I reached the stairs I found one of the most terrifying sights in his life. The corpse of my brother, James Potter.

I was close to a complete breakdown and if not for one tiny thing I would have probably sat there and cried myself to exhaustion. This tiny little thing was a voice. It was weak and small, but unmistakably the voice of a young man. "Help …" And it was coming out of Harry´s room.

It took all my will to get up there, but somehow I managed. What I found was a terrible sight, even worse then before, Lily´s body lying protectively in front of Harry´s crib. However there was also a spark of hope, so to say. For in the crib sat a young boy of maybe three or four years. He had blond, spiky and gravity-defying hair, sky-blue and tired eyes and his clothes looked rather strange. But the important part was that he was cradling a little bundle in his arms, which I undoubtedly knew was little Harry. From the movement of the bundle I knew one thing: Harry was still alive.

But just when I realized this, another thought came to me: How were they found? The answer to this seemed pretty easy: Wormtail! He was the Secret Keeper! He was our friend and he had betrayed us to Voldemort! I´m going to kill him! But just when I was about to stalk of I heard the young boy speak again and this time he sounded even weaker.

"Help, please …"

I was ringing with myself, on one hand I couldn´t let Pettigrew go unpunished, but this boy and Harry …

Ok, first the boys and revenge later. Maybe I can even get Remus to help me with the traitor…

For now we needed help here and there was only two persons I could trust right now. Summoning a Patronus I send it straight to Dumbledore and asked him to clear the way to his office. Shortly after I conjured a second one and asked Remus to come to Dumbledore´s office. But before I could try to move the boys I needed to make certain they were okay.

"Hey there, the name is Sirius. Who are you?"

The boy looked up at me with extremely tired eyes and he had to blink three times and shake his head to clear it enough to answer me. When he finally seemed half awake again he focused on me and answered. "Hi, I´m … Roxas … *yawn* Sorry. Could you help us please?"

"Of course I can. But first are you okay?"

"Tired, extremely tired and the little one here is as well. You won´t believe the evening we had."

Looking around at all the rubble, but firmly keeping my eyes away from Lily, I answered "I think I can believe it. Now I want to bring you to a safer place. Are you up for traveling?"

"Yeah, but if you tell me where to I can make it faster."

"You can? Okay, how do you do it?"

"Well can you concentrate really, really hard on where you want to bring us?"

Laughing at this innocent little boy I nodded my head, but made sure to keep eye contact steady. After all this could still be a disguise of a Death Eater, but for now I could do nothing else, but to trust this little guy. He just looked thoughtful after I had nodded, but after some seconds he scrunched his eyes shut in concentration. After half a minute I wanted to say something, but was interrupted by … darkness? Whatever just happened, one moment we were in Godrics Hollow, the next everything went black and finally we stand in the middle of Dumbledore´s office in Hogwarts. Something was definitely strange here.

Just when I found my voice back, I saw the young boy sway a little, but still he kept a firm hold on Harry, making sure he didn´t fall. For a moment I was unsure of what to do, but when he swayed again, I quickly led him over to a chair, which I transfigured into a couch midway. I sat him down and immediately he curled up on the couch and not even three seconds later he was asleep. He really had been exhausted. Still all the while he had held Harry close and even now he was protectively between me and Harry, while also making sure that the one-year old was as comfortable as possible.

I don´t know exactly what was going on here, but one thing was for sure, I was going to get some answers one way or another. For Harry´s sake, because that would be what James and Lily would want me to do. Revenge could wait for later.

Without another thought I sat down on the couch as well, purposefully staying close to my two charges. For now I would protect them, that is the least I can do…

AN: I know, probably rather confusing for now, but you will have to wait for the next chapter to get most of the questions answered. I´m sure Dumbledore will know or at least figure out most of the answers.

For those who read my other stories and especially 'A Fox and a Sword', you probably already know where I will go with this story or at least have a vague idea. The rest of you will just have to wait like everyone else. Till next time dear readers.
