Origin of sin

Chapter 2: Thrill of the Kill

Death Eaters. They were Voldemort's loyal followers, Wizard and Witches who chose to walk the path of evil.

The Wizarding world was terrified of them and now. Any normal man would have frozen in fear, but he did not. Reacting quickly the young man pointed his wand and the first curse flew towards the masked man. It hit him dead on in the chest and flung him across the space against the front door. He hit the ground and did not move again, blood trickling from his mouth. He was unconscious before he had time to note the boy's presence. Harry took the stairs in one leap. All that was on his mind was to get to the living room, where blood chilling screams echoed through the house. Oh, he knew such screams all too well. He had heard them much too often in his visions, but for the first time he recognized whose they were. Apparently there were more of the robed men and they had decided that his Aunt would be a nice toy.

Harry crept towards his destination and carefully peered into the room. It had been cleared of all furniture, and in the centre the Death Eaters had formed what Harry had come to call, 'The Circle'. The Death Eaters were positioned around the body of a woman on the floor. It was his Aunt Petunia. They were firing curse after curse and one could practically feel the excitement in the air. Laughter mixed with the screaming and it reeked of the laughing man's glee. It was sickening, yet for some inexplicable reason that Harry couldn't understand, entrancing at the same time.

The scene that he was witnessing was taken right out of his visions. The seconds ticked by with agonizing slowness and as Harry watched, something in him began to change, to twist in his chest like a poisonous snake before striking. It had been growing inside him all summer, getting stronger, more vicious. And now, it no longer wanted to remain hidden. Now was the time the darkness within Harry took over.

He stepped into the doorway. Some of the Death Eaters noticed him, but turned to his Aunt again after looking at him with twinkling eyes. Harry paid them no attention, as his eyes were locked on the form of the tortured woman on the floor. It was one thing to see it in his dreams, no matter how real it seemed, and absolutely another to see it before him and know it is real. It was as if he was under a spell. All conscious thought was washed away as he was transported to the world of his dreams. For so long he had seen it, "done" it in the realms of his visions and now, here it was. His sweet drug, the one thing that both scared him and excited him as nothing else could. The screams ceased as a Death Eater released the curse aimed at the woman. A sudden urge to see if he could do it, could feel the same way he did when he slept, flowed trough him. His attention was drawn to two other figures in the room that were cowering in the corner. The Death Eaters noticed and their eyes ablaze they moved so the young wizard could see his uncle and cousin. A malicious smile crept onto Harry's face. He had no more doubts. His aunt may not have been so bad, but these two deserved everything he could throw at them. "The one good side of being Voldemort in your dreams- one learns a LOT of dark spells" mused Harry Again he didn't notice the strange behavior of the people around him – somehow it felt natural. One of them hovered the couple of enormously fat male Dursleys in the middle of the circle, as another moved the now still woman out of it. Unconsciously Harry took the only free space in the Circle - the middle. His eyes clouded and his lips pulled in a snarl he chanted his first spell.

"Inversio defieus!"

The purple beam hit the chest of a terrified Vernon Dursley who only shrieked, he didn't even have time to scream properly, before his skin burst in an explosion of blood and peaces of it rained around the room. Emerald eyes closed in ecstasy as warm blood trickled down the pale features of the young wizard and once they opened again those in the room that had where to move, took a step back. The eyes were shining Avada Kedavra- green with snake-like black slit pupils. Under the startled and somewhat scared gazes of the masked men he liked as drop of blood of his upper lip and fired again

"Bolideo!"

A ball of green flames about three feet wide burst from the tip of his wand. It slammed with vicious force into the sobbing boy on the floor, hurtling him across the room and into the wall Unbearable light exploded as it hit. The Death Eaters had to cover their eyes to protect them from its force and the wave of burning-hot air that wove through the room. When the fire died down, the Death Eaters dared open their eyes. Harry was standing unmoving, completely unfazed by what had just happened.

The only visible difference was the satisfied smirk on his face. Tracing his gaze across the room and the hole in the wall the Death Eaters stared in awe at the crisp-burned thing that was once Dudley Dursley.

They turned back to look at Harry, all of them, even those who had questioned their Master's decision to send them on this mission, seeing him in a new light and all doubts were washed away. Harry was currently moving to kneel next to the still twitching skinned body of his uncle. He prodded the raw flesh with his index finger until he got an almost inaudible pained moan in response. Satisfied with the level of coherence of his victim the young man spoke. "It seems me and you have some unfinished business," he began rising and again taking aim at the thing before him. "Let me repay you for all that you have given me 'from the goodness of your hearts.' This my dear Uncle Vernon," he spat venomously, "this is for 11 years in a cupboard..." His wand moved in a slashing manner over the left shoulder.

"Deficio!" A skinless arm was severed off. "…This is for starving me…"

He used the spell on the other arm "…This is for beating a helpless child …"

Again he used his wand over the left leg. "…for tormenting me , making me believe I was worthless…"

Another slashing movement later and the right leg followed the left and the two arms "…For using me as your personal slave…"

He moved to step with one leg on the stomach of the dismembered Dursley and looked in the man's eyes before, "…and that is because you simply don't deserve to live…" He finished coldly and with one final effortless curse, a fat head rolled on the floor in the destroyed living room of number four Privet Drive. The laughter of the one responsible for her unnatural movement of the severed body part rang in the air at its wake. Stepping away from his handiwork Harry Potter for the first time in his life knew he was doing what he was made for.

"Master was right" one of the Death Eaters said, "The boy will be a good addition to his ranks. He has everything needed for the job."

"Indeed," drifted the voice of...Bellatrix Lestrange? "I never thought he had it in him!"

"Had what in me?" came the cold voice of the boy, no, man which had finally turned to face the others in the room.

"What is needed to be one of us. What is needed to kill in cold blood and enjoy torturing the 'innocent.'"

"'Thrill of the kill.' My boy, I never thought you had it in you."

"And I proved you wrong, Bella?" The masked female Death Eater stared at him for a moment but dismissed whatever it was she thought she saw and answered. "You did, more than did. But enough of this," she pulled up her mask grinning madly with an insane gleam in her eyes, "Master awaits his newest recruit! Welcome to our fold Harry Potter!"

She moved to embrace him, but was thrown away with one shove from Harry, whose eyes had returned to their normal deep green color albeit with a coldness present in them that had not been there before. Dazed and confused she landed in a heap on the floor raging at the act of disrespect and disobedience. The others were slow to react but a few seconds later caught up to what was happening and their wands at the spot where Harry was. But there was no one there…

Ten minutes later Harry sat on the living room sofa thinking. He watched the last remaining Death Eater that was still alive trying to drag himself to the door. He was missing a few body parts and Harry had to admire the man's strength. Deciding what he was going to do, he hastily sent an "Avada Kedavra" at the man to free him from his torture, without even being surprised that he could do such a powerful spell 'hastily'. He quickly packed his trunk and was downstairs again in a matter of minutes. He entered the living room and after making sure all the Death Eaters were indeed dead, his Aunt was still alive though had been unconscious during the proceedings of the evening he left the house, which he would not see again in many years.

A disillusionment spell, broom flight and a few hours later Harry Potter was standing in front of "The Leaky Cauldron". He removed the spell off himself, drew the hood of the robes he had pulled on and entered. A few of the visitors looked suspiciously at him but after seeing that he wasn't doing anything to endanger them got back to their drinks. Harry moved to the counter and paid for a room and supper under the name Seamus Finnigan.

Later as he ate, Harry wondered why the Order of the Phoenix or the Ministry of Magic's Aurors hadn't come to his relatives' house despite the huge amounts of magic used. Furthermore he was mystified how Voldemort's minions had broken Dumbledore's wards. Harry already knew that 'Voldie' was powerful, maybe he had finally become more so than the old Headmaster. If that was true his current plan would need some rethinking. He had decided to head for Hogwarts and make the Headmaster train him and somehow hide any changes in his persona that would raise questions. But now he wasn't so sure that was so wise since it was the same Albus Dumbledore that needed him- a teenager to defeat his enemies. "Is there anyone more powerful than Voldemort anymore?"

"Sure there is kid."

Harry jumped at least a foot above his chair and choked on his food when he heard the voice. A strong hand hit him between the shoulder blades to help with the food he was choking on. It worked. The young wizard swallowed and turned to look at the man behind him. He was tall, perhaps over 6'3" feet with pale, pale skin and platinum hair, to rival Draco Malfoy's. Golden eyes looked back with amusement.

"And who would that be?" asked Harry once he found his voice again.

"You," said the man shortly, but confidently.

"Me? Ummm...ok," Harry said as some things occurred to him. "Why don't you first tell me your name and how the hell did you answer a question I believe I didn't say out loud? Perhaps then we may…talk"

The stranger chuckled.

"I am Serth Blake. And I answered your question because I "heard" it. I am skilled in a form of Legilimency that doesn't require an incantation or eye contact. Some call it 'telepathy'." Harry stared at the man. So, he could hear thoughts?

"If you could hear what I'm thinking, answer me why do you think I am the one that is more powerful than Voldemort?"

"Because of what you are, my boy. I know that you have already guessed part of the truth but there is much more to it than you think"

Harry would have been startled again if it weren't for the fact that this particular night was already far too surreal for him, so he decided that since they could, it wouldn't hurt to keep the conversation in their heads. That way there was no way someone could listen in on them.

"And what exactly am I?"

"You are like me, a day walker. We are vampires, if you would like to say it like that, but we are much more that the ordinary Clans. You know of vampire Clans?"

"Hmmm...I think I do. Desimonies, Shamt, Zesiotti and… Nievi? But I can't remember anything being said in my Defense against the Dark Arts books about Blakes? And, excuse me, but what do I have to do with vampire Clans?"

"Everything . You are… will be…one of us. It is the legacy that is bestowed to you by blood, child"

"I am no child!" Harry's anger flared. "How dare he call me a child! I have not been a child for a long while, tonight sealed that even more so!" Images of the night's events flashed trough his mind and his face welcomed a wide grin.

Serth's golden eyes sparkled with mirth and he chuckled at the boy's antics.

"Shush, child." A very animalistic growl came from the young wizard in the room. The man simply smirked at him as if he had proved his point. "You are a child and will remain one until you earn the title of a man."

Harry narrowed his eyes. "How dare he…"

"Is that so Serth? Tell methen- how many should I kill to earn the title? I am sure that you had seen in my mind what happened tonight…" he spat at the other.

"It does not matter…much… how many you have removed from this mortal coil. Being a man is more my child. And that is why I am here-to show you, to teach you." The beautiful man smiled showing snowy pointed fangs.

Harry scowled at the man.

"I don't need you to teach me anything. I am perfectly fine as I am and unless you value your life very lowly you will leave me alone!"

Deep melodic laughter rang through the room. The man was laughing at him!

"Do you honestly think you could back that threat with action? Well let's see you do it..." he finished opening his arms as if to welcome him.

Harry blinked. He had single-handedly killed more than ten people that night without breaking a sweat and incredulously enough with no regrets for his actions. The man knew that, yet he still called him a child and challenged him as if it were a game…Reassessing his position he decided that perhaps a more to the point attack was his best chance. He would not last long against the vampire should it turn into an all out duel. Deciding that in the span of a second or two, he worked on a diversion. "Why do you challenge me vampire. There is no need for us to fight…"

"No, there is a reason. You are not all powerful child, and the only way to learn that is experience. Pray you make your share of mistakes against an opponent as me, were they don't seek your demise and will let you learn from the…"

Serth didn't have the chance to finish his thought. "Ah, the child is resourceful! Nice diversion…even if a little obvious…" the elder thought as he dodged the killing curse.

Before he knew what was happening Harry was pushed face first into the wall, something cold and metallic against the side of his neck.

"Impressive my child. But you have much to learn," Serth murmured the cold breath tickling his neck, "So much more…"

The metal sliced through the skin and cut its way through the artery where hot ruby-red blood rushed. At first he didn't feel much, just the stinging of the cut until a cold feeling enveloped him and dark spots claimed his vision. The shadows danced as he was released from the other's grip and slumped on the floor. He tried breathing but it did no good. Never had he felt so cold, so alone, so… He made one last attempted and lifted his eyes to the man but all he saw was a blurry figure and a brief flicker of bright light as the metal reflected the fire in the fireplace. There was no rush of memories, no strange thoughts of why one exists. Then the darkness claimed him…and his being was engulfed by unimaginable pain for the second time that day.

Pain. It was all there was. He had lived his life in it, he knew nothing else. It was his heaven and hell, his light and his darkness. He was the pain and it was him. It was a poisonous snake coiling around his soul and devouring it, releasing it of its humanity and twisting it into something new and more powerful than before. He was ripped apart and then slowly put together into something better. A thing that lived in the darkness and was a part of it. He was a slave and a master, everything and nothing at the same time. And in that precious second he was part of the universe herself and discovered it was a place where lived many shades of gray and nothing was simply dark or light. And then the shadows claimed him again.

The shadows were separating themselves from him once more and creating another being. He could more sense it that see or hear it but when the demon-like winged thing gave its message he understood.

"Welcome little one. Or should I call you by your rightful name Deamon?" The thing was amused. Wary of the shadow creature he tried to ask, "Who are you?"

More amusement flowed from the creature as it answered. I am your power, your future and past? I am your all. Do not be afraid of me. You have a great destiny Deamon and I am sad to say that your duties will not lessen with time. But have no doubt little one that you will be great and shall know happiness in your own way. One day you will be ready and I shall come to you my Lord, but until then learn, work hard and don't give up. Experience all you can and be ready. Be open to possibilities and be wary of all. We shall come to help you if need be, but it would be for the best if we don't."

The shadows surged forward and for a second he was one with them. "The power you have now is nothing compared to what truly belongs to you my Lord. Be safe." They whispered to him and left him.

He woke up very slowly, coming into consciousness to be greeted by a sudden spell of dizziness. Slowly opening one eye after the other he took in his surroundings. First thing that hit him was that he was apparently alive and the second was the darkness. It was darker than the darkest night. But what surprised him to no end was that he could see despite it. He could make out even the smallest crack in the wall; the sound of a bug's delicate wings disturbing the air and the sound of its little heart; the creak of the wood behind the door. Just as he reached for his glasses to see if they were still on him, he heard a low thumping sound. Instinctively he knew that another human was approaching but was still far away. The sound seemed to be changing direction and going away from the door. He almost sighed in relief but could not master the strength to do so. He surrendered to his fatigue and lapsed into unconsciousness again.

Noise. Head...pain…damn that noise! Such were Harry's jumbled thoughts the next time he woke up. The noise was actually the other two occupants of the room and as soon as he came to his senses the raven-haired youth heard what was being said.

"…Look at it! They actually had to kill it for it to come to its 'powers'! I cannot believe they are giving him the honor to forgo the training!"

"The Master said he is suitable and Master has never been wrong…"' Ha! I

"Yes, yes," the voice was exasperated, "but there always is a first time!"

"There is truth in your words but lets discuss it another time. I think he is waking."

Very slowly and in quite a bit of pain, Harry managed to open one eye enough to view the room. It was still dark and there were two occupants besides him. Both were boys and both could easily be classified as beautiful without a thought. One had long brown hair that spilled over his shoulders and shone with metallic light every time it caught the non-existent light in the room. His features were sharp, but not too much so. His eyes were the deepest nigh-sky blue and held a hard edge in their depths. The boy was standing at the foot of his bed and looking over him in disapproval from his impressive 6'5". The other was sitting in a chair on his left holding a short sword and a piece of cloth. He must have been polishing it. Seeing this Harry realized that both boys were quite heavily armored, which in no way hid their god-like physique. The second boy had features just as sharp as the first but his obsidian eyes held softness that the other boy's did not have. The strange thing was the sitting boy's hair was gray, but not the same gray that old men had. It was healthy looking and even color and was held in a waist-long braid.

"Hello. How are you feeling?"

Harry closed his eye and tried to say fine but it didn't work. Opening his eyes he looked at the gray-haired boy and managed to croak "…Water…" and shut his eyes once more.

After something that suspiciously sounded like a "Weakling" from the boy at the foot of the bead and the sound of water pouring a goblet was thrust into his hand and he was helped into seating position. Greedily gulping the liquid the burning in his throat eased.

"Where am I?" he asked after a few minutes.

Both boys looked confused and then shocked. They looked at each other and back to him again. The boy which was complaining about him earlier shook his head and for the first time said something to him.

"You mean to tell me you didn't come here willingly? Dear Salazar! What is the Master thinking!"

He continued to mutter about incompetent Masters and crazy old fools while Harry kept trying to get either boys attention until his anger got the better of him

"Well, so nice of you both to clear that up for me!" he snapped, "Now I know exactly where I am and why the hell I am here!" He finished his eyes ablaze with exasperation and anger. He was in an unknown place, with people he didn't know after having one of the craziest nights ever - and that was saying a lot seeing as he was The-Boy-Who-Lived - getting his throat slit open and living through the worst pain imaginable and not so imaginable, seeing talking shadows calling him "My Lord"… It was simply too much and his fuse was short enough as it was.

They glared at him and he defiantly glared back.

"You are at the United Academy of the Clans. It is where the best of the Clans' offspring comes to prepare for life and learn the dealings of our society. It is a great honor to be accepted. Only those that have shown promise and power are welcomed here. Why you're here I cannot know but if Master brought you here, then he must have a good reason. My name is Velin and the boy beside you is Soalr and the Master asked us to show you around."

He looked him over and continued in his cool tone, "and if I'm right we would have to explain our culture too…"

"Since I don't think you know much of anything we'll begin with the basics," started the grey-haired boy, Soalr, once again and plunged into an explanation of vampire society and customs which lasted the better part of the afternoon.

Harry listened carefully and was frankly fascinated. It turns out Serth was the Master of the Academy and Head of the Blake Clan, part of which were his current companions. All vampires in the Academy were of pure blood and rarely did a turned vampire receive the honor to become a student here. He himself, he was told, was a Larin, or an inherited vampire. It was a rare occurrence but usually it happened when the vampire blood is diluded and it usually begins to take dominance once the child turns 16, which explained his bloodlust the previous night. The Blakes, as it turns out, were the lead clan and also consisted of mostly warriors and scholars, strange as it sounds. This perfect balance has ensured the Clan's dominance trough the ages and also its anonymity. To the outside world, the Clans were always fighting one another but in truth one of the Shamt Clan or the Desimonies were always trying to overthrow the Blakes, who were in fact too good at hiding their existence thanks to their brilliant scholars. Their warriors were known for their bloodlust and viciousness in battle and feared among the vampires. Many of the day walkers were positioned in the Wizard and Muggle worlds and have great power in them. Only the Blakes were day walkers, which was one more advantage on their side.

The Nievi were the Eastern European Clan and the second most powerful. They had great history and had fought many battles, but in recent centuries had settled into a more peaceful existence to recover from the millennia of warfare.

The Zasiotti were the Clan of the Priests, as they were called, they were the ones to see when you had unorthodox needs or desires. If you could pay, they will deliver.

Usually those three Clans got along well and any disagreements were approached with cool logic and understanding instead of a blade's edge and battle cries.

"…Insulted his fangs and Slytherin declared war on him…"

"Wait, wait, wait! You mean to tell me that Slytherin was one of The Old! And was part of the Blake Clan? Shit! Holy mother of … Why! Why the hell always ME! I mean Merlin! I am family with my worst enemy! To top that he is the only heir of Slytherin…"

Soalr interrupted him here by flicking his braid over his shoulder.

"He isn't the only heir. If I understand it right, and I am sure I do, the Master said that you were the only other heir of the Great One. Your mother's and father's family both had the blood of Slytherin only it was far too deluded to show in them. You, on the other hand, have more than enough, not to mention that the other Heir transferred his blood right as one on you along with his powers when he tried to kill you. It's one of the oldest rules- no Heir can kill another as long as a legitimate blood contract had not been conducted and a duel or all out war declared."

Harry was stunned into silence.

"Out," he whispered, after long minutes in which the other occupants in the room had forgotten about him and had begin a discussion on the newest design of the school's armor. "And put fire proof charms around the room on your way unless you want it completely destroyed."

It was the other two's turn to blink in confusion

"OUT!"

The shout seemed to pull them out of their stupor and for the first time that day they saw why the boy that they presumed too weak to even match the lowest vampire was the Heir. His eyes shone with the green of Death and his pupils were like a snake's. His fists were clenched so tight that blood dripped from his palms where his nails cut into it. He was still sitting cross-legged on the bed but the sheets were smoking around him and an aura of green flames flickered across his skin. Able to recognize danger when they saw it, both boys hastily left, throwing a couple of strong fireproof charms in the room.

As Soalr was closing the door, a blood freezing scream sounded from inside. It was the scream of a madman, an animalistic sound filled with anger of the strongest kind and promise of murder, of pain and loss. Then, all stilled until the explosions and crashes came from behind the door. The two vampires were quite dazed at the amount of power they could feel being used in the room. Cautiously they took a few more steps away from the door. Neither was sure if their charms will hold against such an onslaught and frankly both were a little afraid of what would happen should they break.

As it turned out the charms miraculously held and the room stood. In the following weeks and months they became a team, not quite friends but stood by each other against the other teams in the Academy. All three excelled in their studies and even though some of the pureblood vampires tried to put Deamon down he never yield. He fought, he broke every rule to get back to the ones that dared anger him and suffered even the harshest punishment without a flinch knowing it was well-worth it . And harsh the punishments were. The last time that he had put one of the Shamt students out of the academy by severing his power's control thus making him no better than a lemmie /the vampires equivalent of a squib/ he suffered 100 lashes, a night in the freezing dungeons naked and a week in the Damned Forest alone, still naked and with no means of survival. But against all odds he and his team prospered and were feared by most by the 3rd year of their training. Deamon had yet to come to his full power but was already a Shadow Mage and a Soul Mage; he was natural at Necromancy and Ancient Dark Arts, not to mention his only real competition in the physical classes was Velar and even the Masters struggled to beat him, which did not happen often now. Velar on the other hand was natural with hand-to hand combat and was a supreme Potions Master who's specialty were poisons and truth serums. He was an Earth Elemental who loved blowing things up and was known for his frequent use of the Unforgivables. But however good Deamon and Velar were they still couldn't match Soalr with blades or strategy. The shorted man was what they called a "wolf in a sheep's skin". He was calm, collected, often he was confused for one of the scholars and he preferred it that way-it gave him the advantage in a fight. All delusions were quickly shed when the confused saw him fight and if it the edge of his sword wasn't the last thing they saw they never forgot not to mess with the Blake warrior.
