I don't own anything in relation to Harry Potter except for my own copies of the books. This was written just for the enjoyment of writing and I make no money off it.

Story Summary:
Post-OotP. Harry's darker side is getting stronger and the lighter side has no problems with it. Harry finally learns to fend for himself and escapes the manipulations of Dumbledore. If he's going to defeat Voldemort, he's going to do it his way and he'll need both his dark and light side to do that. Eventual H/Hr.

Author's Notes:
I just got a new playstation game: Prince of Persia Two Throne, and I really liked the story line. After playing it for a bit, I got an idea for a fan fic that wouldn't go away so here it is. Oh, and for all those that have waited for the next chapter of 'Proeliator Umbra', I apologise for not posting in the last month but I had my mock GCSE exams to do. I now have a lot of free time so I will get it posted soon. I just had to start this first. Coincidentally, I got 'Two Thrones' as a gift for going to my exams.

Chapter One
Meeting Myself

It seemed to take Sirius an age to fall: his body curved in a graceful arc as he sank backwards through the ragged veil hanging from the arch. Harry could see the look of fear and surprise on his face but as it rounded upon Harry, it became a look of disappointment and sorrow. The look that just said, "This is all you fault, Harry."

Harry woke from his all too frequent dream, sitting up in his pitifully small bed: his breath heavy and sweat pouring off his body. He woke up silently. He had learnt over the first week back at the Dursley that he had to suffer quietly if he wanted to survive this summer. He had been beaten by his uncle a lot more this summer. It seems that the warnings his uncle had gotten at King's Station did not deter him from treating Harry poorly but only spurred it on.

Harry could never remember when his body had sustained this much damage from his stay at the Dursley's. His body usually healed his bruises and cuts quite fast but this summer, there was nothing. These could be seen quite clearly on his bare chest and back like he did now. If he didn't know better, he was getting worse. That could have been from the extra beatings, his poorer than average appetite or his constant lack of sleep.

He put his head in his hands and quietly cried: mourning the loss of yet another that died because of him. Of course, it was all his fault wasn't it. If he wasn't the prophesy child, all of this would never have happened. His parents would still be alive. Sirius would still be alive. It was all his fault wasn't it?

He walked silently to the bathroom, his head hung in shame and despair. He got to the sink without even lifting his head. He leaned against the sink for a minute just to regain his composure. He slowly lifted his head and was shock by the reflection he saw in the mirror.

There were white streaks through his trademarked raven black Potter hair. His eyes were not the usually fiery green but a dark green, dark enough to be black. His eyes were blood shot, crimson tendrils marring the images behind the lenses of his glasses. His muscles were larger and his shoulder broader but the cuts and bruises were missing.

Harry looked down to inspect his body but he saw the usual skinny body mutilated with bruises and cuts. That didn't make sense. He looked back at his reflection and again was affronted by the same illusion. It was after a moment that he realised that his reflection was smiling, apparently amused at Harry's plight. It then said, "Hi Harry."

Harry stumbled backwards at this but there was absolutely no reaction from his reaction except for his grin getting bigger. Yes, he was definitely amused. Harry asked, "Who are you? What are you?"

"Why Harry, I am absolutely insulted that you cannot even recognise yourself. That's right. I'm you. Well…only technically."

"What? What do you mean?"

"I am…sort of your dark side. That bit of you that isn't all high and noble, that bit of you who doesn't let the world walk all over you, that part of you who screams out for Voldemort's blood! I'm the darkness to your light, I'm the cold harsh reality to your naïve innocence, and I'm the Slytherin to your Gryffindor" said the reflection and as if to back up that point, the lights started to dimmer and a non existent wind happen to breeze through the reflections hair.

Harry was visibly scared now, and I must add that it is quite impressive to scare someone who slew a basilisk and faced down Voldemort twice just to name few off the top of my head. He managed to stutter out, "What do you want?"

"What do I want? I want us to survive the death eater attack that will start here in twenty minutes."

"Huh?"

"To give a proper explanation, I guess I have to start at the beginning. It all start on that fateful Halloween that Voldemort thought he had enough power to murder a one year old. You may only remember flashes of memories but I remember it all in minute detail. I remember we saw the look of fear in our father's eyes when he ran to fight that monster. I remember when the spark of life ebbed away from our mother's eyes. I remember the look of pure terror in Voldemort's eyes when he realised that he was going to be 'killed' that night at the hands of a baby."

"Pretty traumatic I must say, for us to have our infantile innocence be shattered like that and to be exposed to that much dark magic and then have part of one of the most evil wizard to ever plague the Earth imprinted onto our soul. Needless to say, the old fool Dumbledore was pissed that his ultimate weapon for the light was tainted so. He also knew that Voldemort was still out there, that we didn't truly destroy him. So he did what he thought was right, he put a magic suppressing block on the darker side of our magic."

"The fool did not realise that in doing so, he had caused us to have a slight case of split personality and our magical core also broke down into two separate pieces, both stronger than the original. Now, you may be asking if I was around since then, why I only have spoken out now. Well, the power of the suppression block was adequate enough to keep me at bay. That is until a most important event that happened during our fourth year, when we finally saw death."

"The senseless killing of Cedric was enough to allow me to start to develop and put a crack into the block on me. I leaked through after that point. When you shouted at your friends, when you were so angry that you spoke back to that bitch Umbridge, when you used the cruciatus curse on Bellatrix, our godfather's murderer and when you trashed the Headmaster's office enraged at the secret that had been kept from you for so long. All of that was me. My essence taking control for a bit and every time it did I got a bit stronger, a bit more influential."

"I being a presence of your mind am much more in tune with our magic than you and I have been able to get a bit more out of the link we share with Voldemort, more than just the occasional vision. I have delved into his mind, only very lightly mind you, and I found out that he has found a way to bypass Dumbledore's precious wards and there will be an attack here soon. Ten minutes in fact and there is no way you can survive it. You need me to make sure you survive, oh chosen one."

"What do you mean; I have been able to fight off death eaters before. I mean all that I have to do is just break those underage magic laws but it would be in self defense. The ministry will believe me know that they don't deny that Voldemort is back…"

"If only it were that simple. What you did not realise was that as we were leaving Hogwarts, our most honorable Headmaster put another magical bind on us, specifically on you. It seems the great leader of the light has no worries about leaving his weapon defenseless as long as he doesn't cause him any grief with the underage magic office again."

"I believe that his thought on the matter from what my light legilimency could gather was 'it doesn't matter if he can't defend himself; no harm can happen to him if he is kept at Number Four Privet Drive.' That's why our aunt and uncle have made sure we stay in the house. Little did he know that our uncle could still hurt us and our passive healing abilities can't even help us. Why don't you think our wounds have gone away yet, like they used to do? And soon, his marvelous genius of wards will do nothing to stop the team of death eaters who will come and murder all in this house, and you can't even cast a single stupefy to stop it."

Harry now was worried. He took his wand from his trouser pocket and cast a quick 'lumos' only to find nothing to happen. He did not even feel the same warmth he felt when he held his wand. Only one word came to mind, "Shit!"

"Now, here's where we can help each other. You have no way to use your magic but the suppression block on mine is fully broken. I could train you to use it properly, but that wouldn't be realistic in five minutes so I need a little favour. You need to willingly allow me to be the dominant consciousness. After I dispatch our killers, we'll go somewhere safe and I'll help you to be able to use my magic to its fullest. When your blocks are removed, you will be more powerful magically than Voldemort himself. So, what do you say?"

"Sure."

"Now before you do you have to know that the first time will be quite painf-"

Harry keeled over, a gasp of pain escaping his lips and his hands clutching his chest. His eyes turned a darker shade and the bloodshot lines snake their way from the corners of his eyes. White streaks appeared in his hair. Finally, he stopped trembling and stood up properly. He said in a much deeper and raspier voice, "Yes, quite painful indeed."

"Hey, this feels weird. It's like I'm not anchored down to my body anymore and it feels like I'm floating"

"Don't worry, you'll get used to that. Now, onto business: I need to have a wand that will not attract the attention of the ministry so let's just take the magical essence from our wand and add a bit of me to it."

"Huh?"

"Just watch." He placed his wand into his wand into his right hand and thin wisps of what looked like black smoke started pouring off it into his left hand and formed a perfect replica albeit it being pure black.

"When you do it, yours will be white. Now let's get something actually good to wear." He put his Holly wand back into his pocket and pointed his black one at himself and he was then clad in black trousers, a black shirt, shin guards, forearm guards, a black jacket and a mask that covered all but the bottom of his face (he could still see through it though). There was pieces of black cloth flowing from parts of his clothes and flew in the non existing breeze. All in all he was looking very ominous.

Harry walked down the stairs and went into the kitchen where he took the biggest and sharpest knife he could find. The light Harry asked, "What's that for?"

"You'll see." He then proceeded to walk out the front door and standing in the middle of the front lawn, he waited.

A minute or so passed, and then Harry threw the knife in the air. There was nothing in the way of the knife though. Yet.

POP!

A black cloaked figure with a skull mask had just apparated onto Privet Drive to find a knife souring for his face. He didn't dodge it in time though and he fell dead to the floor, blood flowing from underneath his broken mask collecting into a pool. The dark Harry simply stated, "That's what it's for."

"Hey, I was just wondering"

There was the sound of twelve more POPs and Harry found himself surrounded by a dozen death eaters who all had their wands pointed at him now that they realised he was there.

Harry decided to address them all, "Good evening ladies and gentlemen. I am pleased that you have chosen for this spot to be the last thing you will see in your lives."

A soft blue pulse rippled through the air, an anti-apparition and anti-portkey ward. Harry then went into a defensive stance raising his black wand. The death eaters couldn't miss the sadistic grin that formed on his face. "This is going to be fun."


Author's Notes:
I will continue this fic if I get a good response or if I really find a good muse for it. If I continue, the next chapter will have a fight sequence of Harry and the death eaters. Let's just say Harry does a lot of ass-kicking. If this story continues, the pairing will definitely be Harry/Hermione (or at least 'Light' Harry/Hermione. It might be funny for the two sides to like completely different people)
