CHAPTER ONE

Cursing under his breath for what felt like the millionth time Harry continued to fight his was thought through the numerous death eaters in front of him. All of which seemed to be determined to stop him, or at least slow him down from getting to his goal. Seeing this and knowing he couldn't let that happen Harry continued to give his all in the fight he was in. Because of this Harry, was quiet literally, cutting himself a clear path to Voldemort.

It seemed that no death eater, no matter how hard they tried, couldn't make Harry pause for even a second as he ducked, dodged, and twisted his way towards the center of the battlefield. Where Voldemort was clearly standing, watching the chaos around him, and obviously waiting for Harry to make his way to him.

Panting quietly, starting to feel the strain of fighting for as long and as hard as he had been, Harry shook himself slight. Trying to get rid of some of the exhaustion he was beginning to feel, before pulling himself once more into his fighting stance. Harry had finally made his way through all of Voldemort's death eaters that had been trying, and failing, to stop him and was now standing directly in front of said dark lord; his wand in his right hand and one of his many blood covered daggers in the other.

"So Potter, I see that you at long last have stopped playing around, and have finally prepared to meet your death. Strange I find myself almost glad to see that you've accepted your fate to die by my hands." Voldemort hissed out as his malicious red eyes glared out at the slightly panting sixteen year old boy in front of him.

A boy, who really more of a young man then anything. A young man who had already single handedly took out nearly a fourth of his army, and a young man who was currently looking at him emotionlessly. Before deciding to reply back to the taunt he had said; in a chilling cold tone.

"Tom I'm always ready and always will be because I don't fear death. If I die I will embrace my death with both hands and with a smile on my face. But can the same be said about you? Are you ready? Are you accepting?" After saying this Harry wasted no time as he sprang right at Voldemort; ready to end the monsters life once and for all.

Only to have to immediately throw himself in the opposite direction when he saw that Voldemort was casting a severing hex at him. Once he did this, and completely avoided said hex with ease, Harry retaliated against the severing hex by letting loose a rapid fire of hexes and curses at the vile snake like man; all of which would have severely maimed, killed or humiliated Voldemort if they had hit him. Mixing in with all these curses a rain of his Basilisk poisoned daggers; all throw with such speed and precision most would not be able to avoid them.

Unfortunately it seemed that not only was Voldemort not most people, but he also didn't only just look like a badly deformed snake. He could move like one as well, because he was able to successfully dodge all the spells Harry had cast and all the daggers that had been thrown at him; even if some of them were just barley.

Seeing the Harry narrowed his eyes and tightened his grip on his wand, as well as pulling out several more of his daggers from the pouch on his side, ready for what he knew was going to be the most difficult fight of his life. On the other side Voldemort did the same thing having learned from experience that underestimating the teen in front of him was a bad idea.

Lights flew from Harry's and Voldemort's wands as both sides continued to fight, neither giving up; both sides giving their all into the fight they were currently in. Harry with his weapons, superior speed, flexibility, creativity, and just pure power was doing everything he could to defeat Voldemort.

But the same could be said about Voldemort, who was using his cunningness, cruelty, knowledge, snake like agility and control of his own impressive power to the best of his ability; all in an attempt to get the upper hand over Harry.

However none of it seemed to work just the way Voldemort wanted it to. Because no matter what he did him, and no matter how underhandedly he tried with his attack Harry always seemed to be prepared; or at least step head. Though the same could be said for Voldemort with Harry attacks. It seemed no matter how much both of them wanted to deny it they both seemed to be entirely equal to one another. This really showed when neither of them were able to get an upper hand on the other in their duel; no matter what dirty trick or creative spell use in their attempt to do so.

That is until Voldemort decided to do something very stupid, as he would quickly find out, and something that he would regret doing only seconds after doing so. Something he often did when he found himself losing, or not winning as quick as he wanted; however rarely that did happen. What he did was cheat; though not everyone would quiet say it was cheating since they were in a war. Too bad despite the fact that he had been chasing said boy since he was born Voldemort honestly knew very little about said boy; or he would have never of done what he did.

What happened was that Voldemort, who was getting very frustrated that he couldn't defeat what he believed to be a simple sixteen year old boy, decided that he needed to do something to distract or devastate Harry. A tactic that had done him wonders in the past against people he believed to be stronger then the boy in front of him.

That in mind Voldemort quickly pulled his wand away from Harry, after sending one last curse out at him to get him even further from his real target, directed said wand at the back of one Luna Lovegood; who was fighting a couple of death eaters that had been trying to attack Harry's back.

Voldemort knew the tiny fay like girl, that was now unknowingly at the end of his wand, was Harry's secretly blood adopted sister. Though Voldemort would reluctantly admit to himself to the fact that he had only just recently found this out this little piece of information; so he was only just getting to use it against Potter.

But none the less he knew that her death would tear Harry apart and make him an easy target to kill; like it had to so many of his oppositions had before. So with that in mind Voldemort quickly cast the killing curse at her; hitting her with the deadly emerald spell before anyone could realize what he was doing, and making her drop dead to the ground where she stood; right behind her brother. Once he did this he quickly turned towards Harry. So that he would be able to get a good look on the boy's face as he realized what had just happened behind his back; hoping to get a good look at the broken look of total devastation on Harry's face as he did so.

Unfortunately, Voldemort's plan didn't go quiet as he hoped it would have. Because instead of being devastated and not paying attention to what he was doing, and therefore being very easy to kill. Harry, after seeing his sister fall to the ground dead, became completely and totally enraged; taking not notice of anything but the need to avenge his sister.

Harry was so infuriated at the death of the last of his family, or at least the death of the only person he willingly called family, that he didn't notice the incredibly dark aura that had suddenly engulfed him. Making it all but impossible to see anything but his eyes; which were glowing just as bright and deadly as the dread killing curse. Nor did he take any notice of the fact that the entire battle field had swiftly stilled and became silent as they all watched the enraged man, in front of them, terror and awe clear in the eyes of everyone watching.

Harry also took no notice of the fact that Voldemort himself had taken a step back from him and had a look pure fear on his face as he did so; looking as if he was facing death itself at the moment instead of Harry. No, all Harry took notice of at that moment was the dead body of the girl he had happily at one point called his little sister. That and the voice in the back of his head that screamed at him to make the fucker who did that to his sister pay and pay back with interest.

Growling Harry decided to do just what the voice said; despite having never listened to said voice before or having heard it before for that matter. So with that in mind, and really wanting the snake bastard to pay for everything he had done, Harry quickly turned his killing curse green glowing eyes toward Voldemort. His body language screaming only one thing to the snake like man in front of him and that was death. Voldemort, who had by now gotten over his first reaction to the aura Harry was giving off, had his wand out with a curse flying from it; flying directly at Harry chest. It was the killing curse of course.

When it became apparent that Harry wasn't planning on moving out of the way of the brilliant green curse heading his way Voldemort became incredible gleeful as he began to believe that what Harry had been (and still was) doing earlier was just grandstanding. That is until Harry still covered, in the now purple, pulsing aura reached up and grabbed the killing curse like it was a ball. (Or the snitch.)

Shocking the already stunned fighters around him, both light and dark, and completely terrifying the dark lord in front of him. A dark lord who was now really starting to begin to regret angering the young man in front of him and one that was beginning to see that he might not be make it out of this fight alive; unlike what he had been sure about in the beginning of the fight.

Knowing now, especially with Harry in the state he was currently in, that he could not win the way he was fighting now Voldemort became despite; wanting to at least make it out of said fight alive. Because of this desperation he began to start throwing every curse, spell and hex he could think of at the pissed off power house in front of him; wanting to somehow slow down Harry so he could escape.

Only for every one of them, every single one of them, to be bashed aside, reflected back at him or absorbed into Harry's aura the very second they got even within a foot of in. The spells that were absorbed where the more powerful dark one Voldemort had fired and they made said aura around Harry even stronger than it already was. Seeing this and knowing no way to deal with it Voldemort went insane (or even more insane the he already was.) from fear; he knew his death was drawing near.

Voldemort knowing this, and knowing he had no way of stopping this, turned to flee; giving up all pretenses of fighting as he did so. But as soon as he attempted to do this he found that escaping was impossible. Because of the numerous wards someone had set up around them; something he knew neither him nor his death eaters had done.

Realizing this and realizing that he just seriously fuck himself over Voldemort screamed in pure frustration; as well, even if he would never admit it even to himself, pure terror. Before he spun around and started firing curse at random people in the crowded war zone around him. Determined that if he had to die then he would do his best to take as many of people around him with him as he did so; taking no care to see if they were on his side or not. Suddenly Voldemort stopped mid-curse, which would have hit a horrified looking second year, and blood dripped down his lips. Slowly as if in disbelieve about what was happening Voldemort looked down at his own chest not wanting to believe what he was both feeling and seeing.

What Voldemort saw the moment he did this was Harry's dagger lodged deep into his chest, so deep that only part of the hilt could be seen; the other part actually being in his back from the force Harry had put in it when he threw it. After seeing this Voldemort couldn't help but turn wide eyes towards whom said dagger came from in the first place. Doing this looked Voldemort found himself looking into the unmistakable emerald eyes of his killer; into the eyes of Harry Potter.

Harry seeing that Voldemort was dying. From a muggle dagger of all things, began to let loose a serious of spells to insure that no matter what, or no matter who tried, Voldemort wouldn't have another chance of coming back to life. Then when Voldemort finally gave one last blood filled rattled breath before death claimed him Harry did one last spell to burn the body to ashes; just to make sure.

Harry seeing that Voldemort was gone for good released his magic and let go completely of the magical aura that had been covering him; having realized he had one when it started absorbing the spells Voldemort had rapidly thrown at him.

Once he did this, the now beyond exhausted, Harry stumbled brokenly over to where his sister's dead body laid. When he got there Harry did what Voldemort had wanted him to do from the beginning and broke down; ignoring the fighting that was still going on around him as the last of the deatheaters were being rounded up as he did so.

Gently Harry picked Luna up, sobbing quietly as he did so; showing more emotion, other than rage, at that moment then he had for a while. As soon as he had Luna in his arms and off of the blood soaked ground, he carefully place her head on his lap and began to softly stroke her head; all the while remembering the great time he had had with his sister trying to loose himself in his memories so he didn't have to accept reality.

The sound of someone clapping loudly suddenly interrupted Harry's memories and caused Harry's hand to stop midway through Luna's hair long silver blond hair. Harry realizing that he was still in the middle of a battle field quickly spun around, wand in hand ready to fire a powerful cures at any moment; despite the exhausted state he was in.

Only to faultier and nearly drop his wand when he saw what, or more like who, was behind him. There, much to Harry embracement for not sensing them sooner, was a group of people behind him. With the clapper, that had caused him to spin around in the first place, his headmaster, Dumbldore, as the leader of them. Highly confused as to why they were all behind him and why they were looking so smug, because Harry was sure they didn't know Voldemort was dead yet, Harry cautiously asked the group; that was now in front of him instead of behind him like they had been.

"Ron, Hermione, Dumbldore, Minster Fudge…why are all of you here? Shouldn't you be helping round up the rest of the remaining deatheaters that are out there?" Harry after saying this watched with confused but wide eyes as Ron sneered hatefully at him. Then, to Harry's horror and complete disbelieve, Ron march over to him until he was standing directly in front of him and spat out in the most hateful tone he could manage words that Harry was sure he would never be able to forget. Those words were.

"We are helping Potter. After all we're attempting to put a very dangerous THING, behind bars where it belongs. We are trying to get a murderer who kills everyone he is near put away for good. And who just so happens to be here right in front of us!" Harry understanding what Ron was getting at quickly got up to his feet; preparing to fight for his freedom. Even though he knew that it would be a fight he wouldn't be able to win; especially with the condition he was currently in.

The others seeing this all raised their wands at the exhausted teen in front of them. A teen that had just saved them all from what would have been a fate worse then death and without an ounce of remorse, or even a bit of pity, they all fired multiple curses all at him, over and over not giving Harry any chance to rest or really dodge any of their spells.

Because of this it was a battered, spell damaged, extremely heart broken, and betrayed sixteen year old Harry that was thrown into Azkaban; by those he once happily called friends. By those he had almost called family.

In his cell, rolled into a corner, an out cold and bloody Harry clutched something to his chest; as if it was the most important thing in the world. And at the moment it most likely was just that important, because at the moment it was the only thing he had one him that could keep him sane in the hell he had been thrown into.
