Sorry this took so long, I kept being interrupted, and it ruined my flow, also it's a long one.
WARNING VIOLENCE GORE AND ADULT THEMES
Hogwarts year 1
Platform 9 3/4 was bustling with students, many attending for the first time, many returning, and a few searching for a certain boy-who-lived.
Watching from the shadows he noted a girl, she seemed intelligent but kept arrogantly quoting books at people causing most to ignore her.
A timid boy clutching a toad said nothing as his grandmother ordered him to clean himself up, buried deep in him was his true self that was almost smothered by rules and an intense inferiority complex.
Standing with poise and grace a family waited for the rabble to move, father and son with platinum blonde hair and an arrogant belief in their own superiority, the mother with golden blonde hair almost as long as her husband's done up in a tight knot, her face impassive and cold like her heart.
Lastly a disorganised family of redheads, the youngest male radiated jealousy like a nuclear reactor, the twins had slightly loose morals when it came to mischief, the young girl however disturbed him, it felt unnatural the level of obsession he read in her.
He ignored the rest as he quickly become bored, and waited for the train to depart.
As the Hogwarts Express elegantly traversed the land, many aboard were keeping any eye out for a glimpse of the famous Boy-Who-Lived, while a certain red head and platinum blonde were actively searching for him, if only they had looked on the roof they would have found him enjoying the rush of wind and speed.
As he enjoyed the feeling he pondered what he had noticed at the platform, he could sense what the people were like but he noticed he could only sense what could be called personality flaws, traits that could and likely would lead them to be his concern, but his attention wandered so easily whereas he could focus on the adults, perhaps being so young they may grow out of those traits? he hoped they would, but wouldn't hold his breath, it was than he noticed something useful being sold by the red twins.
He glanced down at himself, deep in him he could sense that the one called Griphook was ready to go back, the interrogations had given all the information requested and having the goblins owing him a favor greatly appealed to him, he reached into his robes.
Gringotts several hours later.
Grodbik sat in his new office, Ragnok himself had given him this account as the account holder himself had asked for him, apparently he had a 'clean soul' whatever that meant, but it was daunting, this was an account older than the bank itself, no one knew how it had been started or who had opened it but the holder of this account was NOT to be denied under any circumstances, he didn't know why that was but seeing that Ragnok himself gave that order he wasn't about to question it, he almost fell off the chair when a large black iron key landed on the desk, he did fall off the chair when a bound wild-eyed Griphook was dumped on the floor by a creature with large fleshy wings and spindly legs, it's head was just a mass of writhing worms which formed a mouth and spoke,
it screeched painfully, "AS AGREED,"
and dropped a folder from... Grodbik decided he didn't want to know, and the thing flew up into the darkness and was gone, now he knew why the roof was shrouded so it was always dark, even as he shone a light into the dark, all he could see was the roof, his response was to call some guards, and open a bottle of Firewhisky.
Hogsmeade station.
The Express pulled in and settled, the children disembarked and began to move, the older one knew where to go and the younger ones were being called, Harry moved in the shadows observing the large man for a moment, he was also not his concern, he followed with the other new ones.
The first years milled about following the large man called Hagrid, they excitedly talked about the school, magic, classes, and many other things including the fact that no one had seen Harry Potter.
They piled into the boats at the lake shore and the boats moved off by magic, the last to leave had one unnoticed occupant, who began gesturing and speaking as if talking to someone.
Albus Dumbledore walked down the staircase from his office, looking like a sunburnt lava lamp he headed to the welcome feast, as he turned a corner he paused, something felt off. He looked around and nothing was out of the ordinary, he closed his eyes, the connection to the wards was fine, but something was missing, he continued moving towards the hall before it hit him, it was Hogwarts itself that was absent, the castle always paid attention the the headmaster even if it couldn't communicate, and now that attention was elsewhere.
The sorting had begun, children moved to different tables, slithering, griffin something, ravenclaw and hufffluff, he was not paying attention until,
"Harry Potter!"
Furious whispers erupted around the hall, children stood and tried to see, but no one was coming forward, and as the noise grew quiet a small voice came from the mob of firsties,
"E-ex-excuse me?" came the frightened whisper,
McGonigal's eyes widened in horror as from the mob emerged a painfully thin, much too short child, his dirty tangled hair had been badly cut, his eyes were a dull lifeless green sunken into a skeletal face, his 'robes' were old and tattered and didn't hide the thin boney arms and legs, he walked up to the stool and as she looked at him and as she motioned to it he flinched, he held his breath as the hat was placed on his head, and as his eyes were covered she turned to the headmaster and gave him a look that would wither a dementor, inside his head all he could hear was the hat laughing it's arse off.
When it's laughter subsided it spoke, "I thank you for the entertainment Lord, it has been a long time since I got to see a show, but first to business, you would fit in any house but if I put you in Slytherin I am certain many of them would not survive, as for gryffindor they tend to not take no for an answer and the result would take longer but would end up the same as Slytherin, Hufflepuffs would not pry but they are observant, the best place for you to do what you came to would be Ravenclaw, plenty of information for your magical studies and they would definitely leave you alone,"
Harry simply gave a mental sense of approval,
the hat chuckled, "I believe your chance to slip out is coming,"
Minerva Mcgonagall had never been so enraged, to see Harry Potter in such a state of clear abuse caused her to snap.
Harry slipped into the shadows as Professor McGonigall chased the headmaster around the great hall, whacking him over the head with an umbrella, which he vanished with his wand, only for her to conjure a larger one and begin assaulting him with that while screaming obscenities at him in such a thick Scottish accent no one could actually understand her.
While all eyes were on this specticle no one noticed the boy who lived slip the hat off and slide into the shadow beneath the stool, he appeared outside the school in the forest laughing, pulling a prank was a new experience for him, but it fit in with his duty after all the headmaster had received some punishment for his negligence.
The chaos in the great hall ground to a halt as the sorting hat yelled from it's stool
"RAVENCLAW!"
Harry stopped laughing after a while, it was a new experience for both sides of him, he would definitely have to experience more of this, he took in the view from the top of a tree on the edge of the forbidden forest, he liked the dark and foreboding feeling coming from the forest and spent about half an hour taking in the atmosphere and thinking. His prank had drawn quite a bit of attention and that may cause him problems, he had considered staying this way but the attention would be an inconvenience, his appearance shifted back to normal and he began walking back to the castle.
Harry arrived at Transfiguration before the other students, as he walked in to the class he noted the cat on the Professor's desk, possibly her familiar since it did seem to have magic almost... oh... it was her, transformed somehow, as he focused he could see the magic holding her in that form was actually quite slight and came from a connection to her soul, he would observe her transform if he could as she would have to before she could teach, he approached the cat,
"Hello kitty, perhaps you'd like these?" he held out a few jelly beans, "the redhead twins sold them to me but I don't like them, I think they called them Skinny Beans," and he dropped them before the cat who scowled while Harry walked to a seat.
After the lesson Minerva Mcgonagall headed to the headmaster's office, she had to inform him of the development and... apologise for almost giving him an umbrella enima.
Severus Snape was off put, the spawn of James Potter looked like him but acted almost amused as he tried to put the boy down, he had thrown advanced questions at him and the boy answered them correctly, he had made snide remarks and belittled him, he even blamed him for someone else's mistake but the boy didn't so much as get annoyed, and why had his appearance changed?
Professor Flitwick was an excitable man, he exuded possion for his craft, and for teaching, but Harry noticed something odd, according to the information provided about the teachers Flitwick was in his 30s so why did he look so old?
The charms lesson was simple enough and the levitation charm was easy enough to pick up, even if one student somehow made his feather explode, at the end of the lesson Flitwick asked Harry to stay behind,
"Mr Potter, the reason I asked you to remain was to warn you about accepting food from the Weasley twins, they are pranksters and sell enchanted food like that, it is ultimately harmless but I thought you should know," Flitwick suggested,
Harry smiled and said "Many have said I looked different at the sorting, I didn't realise they were the cause, at least now I can offer an explanation, I guess they got you too? after all you don't look 33,"
Flitwick laughed showing his slightly pointed teeth, "Sort of," he looked around, "they are extremely clever and inventive so I offer some pointers, after all creativity is something we wizards can lack and so should be encouraged, I 'accidentally' ate an 'old man mint' they left behind on my desk, purely an accident you see," he smiled, "well you'd better get going, don't be late for your next class," his head of house dismissed him.
During history of magic Harry seemed to doze, but had someone been sat near him they might have heard him softly speaking,
"He shouldn't be here,"
"He is not teaching, he is quoting, he is lost,"
"fine, this is your domain and I will not interfere,"
Defense against the dark arts was interesting, not for the lesson as the teacher was stuttering so much he might as well have been speaking greek, but for the reaction of something inside his domain, a certain small rat seemed to be able to unerringly run towards the only way it could possibly get out, it was drawn to the professor, he had gone back to the room when no one was there and there was no reaction, it was only when he got close to the professor that it reacted. That night he returned to his domain and asked his enforcer demon 'Slabhead' why there was a single real rat in his domain, he was surprised to be told that this 'rat' was actually a fragment of soul, tiny and too weak to be able to get any information from, so they put it in a rat as it couldn't move on while incomplete, and without a vessel it would dissipate.
Things progressed for the next month, when asked about his childhood he said that he had been lucky and had fallen in with a good crowd, saying he found himself in america and had 'joined' a little town. When pressed further he would simply state 'it's private' and usually people would back off, the headmaster of course would immediately investigate but would only find useless tidbits.
What was getting to Harry was the unpunished crimes of many students, hexing in the halls, yes some was playful and not meant to harm, but much was not playful especially from the slithering house, or what it Slytherin? whatever, their head of house was particularly unfair and covered for his house even sometimes punishing the innocent students, but this was not his domain and not his responsibility, so he could ignore it.
He had started talking to other students about magic, asking about what they were taught at home or if they were from non magical families what their impression of the wizarding world was, his understanding of the world grew as his fellows answered, some were taught simple spells and how to approach magic, and the others paid attention and asked questions, and while one of these discussions was going on Harry cocked his head slightly, no one noticed the one sided conversation he was having,
"Why should I involve myself?"
"It is unfortunate, but isn't my responsibility..."
"Interesting,"
Hermione Granger was terrified, the large smelly monster was after her, she had to hide and fast, she quickly slipped into the bathroom and closed the door carefully hoping that it wouldn't find her, unfortunately while it's eyesight was terrible it's hearing was excellent and her panicked breathing led it right to the door.
"TROOOOOOLLLLLLL! IN THE DUNGEON! thought you aught to know..." *thud*
Pandemonium.
"SIIIILENCE!" Dumbledore yelled, "you will please, not panic," as he gave orders for the students to return to their dorms no one had noticed Harry slip into the shadows.
CRASH the door exploded inwards as the troll's club smashed it, Granger hid in a stall curled up into a ball and hoped it would go away.
The prefects began a head count as they headed for the common rooms.
The troll looked around the room and raised it's club about to smash the odd wood things, when it was yanked backwards out of the door and vanished around the corner it's club hitting the floor with a loud THUD which made her squeak in fear.
As the Ravenclaws entered the common room the prefects had started to ask if anyone had seen Potter, only to spot him sat with his feet up on a settee reading a Defence book, he cocked his head,
"what?"
As Harry listened to his housemate excitedly explain what was going on part of his focus was internal.
Petunia crept around the terrifying town, hoping to find a car or something to help her, she turned a corner and in the distance she saw something large and human shaped sat down on the floor, it had some sort of meat and was eating it, as she crept closer she realised with horror it was eating a leg, and when she noticed the pile next to it was the remains of her husband she screamed and ran.
"Professor Quirrell yelled about a Troll being loose in the dungeon before he fainted, then the headmaster yelled for quiet and ordered everyone back to their common rooms," one girl babbled,
Harry cocked his head, "it was in the dungeon? where the Hufflepuff and Slytherin common rooms are?"... horrified silence.
Petunia ran screaming, the thing was chasing her, pity she didn't realise it was too big to get through any of a number of alleys, it soon smashed her with a tree it had uprooted, and picked her up, as it walked back towards it's unfinished meal it snapped her legs so she couldn't run, and she got to watch it finish it's dinner.
"So they started searching the school floor by floor?" Harry asked,
"well how else could they find the troll?" boring boy no. 27 asked,
Harry raised his eyebrows and lifted his wand, "point me, headmaster Dumbledore," his wand span and pointed up and behind him, more stunned silence, he was beginning to enjoy this.
Petunia woke up just in time to see teeth.
The year progressed without too much drama, and on his night wanderings he did come across an interesting mirror, easily deciphering the inscription he thought this might be useful, but when he returned the next night to try and see if he could replicate the effect since the mirror was not his to take, he found it had been moved.
He headed to the school broom shed, much to his surprise he had discovered in their first flying lesson that he rather enjoyed the activity, when he reestablished his domain he would definitely fly more, but outside it he had to rely on the school's rickety brooms, he sent one of his minions to have Gringotts order him one.
Grodbrik shuffled papers from his other clients, serving his main one was... unnerving but luckily quiet, he placed the papers in a tray which vanished, the rest of his day was looking quite * THUD * the room shook as the thing landed and he looked up trying not to pee himself.
Stood in the middle of the room was a large... thing... it looked vaguely human as it wore what looked like a butcher's apron, but that was it, it's arms were grey and covered in purple veins it had three fingers and it's legs were the same including the odd shaped hands for feet, no head he could see just what looked like a large rusted metal wizard's hat attached with large metal bolts which judging from the blood slowly flowing down it's torso were bolted into it's body, it walked forward with an oddly graceful stroll and gestured to itself,
"HAT!"
Grodbrik just sat there for a few seconds before copying the gesture, "Grodbrik," he almost squeaked,
The thing reached into it's apron and placed what he could see was an order form on the desk, "BROOM!" he then stood motionless.
Harry performed a few tricks on the school broom, he didn't push it too much as the thing felt as if it would fall apart if he pushed too hard, but he was enjoying the flight even if it was a little slow, as he headed in the direction of the forest he glanced around and spotted a purple turban far below.
Quirrell had apparently come out of the castle which was odd, the man usually didn't leave the building, before Harry could ponder more the broom jerked to the left he pulled it back only for it to dip suddenly and nose dive, he felt to magic in it break and he plummeted into the forest.
The entrance hall was empty when Harry walked in, so no one saw the darkness rolling off him like steam, his eyes glowing green with a tinge of red as he looked around his rage causing the flagstones to crack underfoot as he walked and suddenly he stopped, he felt it... Hogwarts's pain as his power flowed unchecked, and just like that the dark mist vanished, the glowing eyes returned to normal, and his rage evaporated, he knelt down and ran his hand over the cracks sealing them up.
less than a minute later a pale Dumbledore rushed into the now empty entrance hall, his wand swishing and twirling as he tried to figure out what had cause the school's wards to... cringe, that was the closest he could come to describing it, once again he had detected demonic power and once again he had nothing.
The next few months passed without major incident at Hogwarts, except for Professor Quirrell pratfalling upon seeing Harry, but in Harry's domain he felt a pull, Vernon and Petunia were unrepentant and he couldn't hold them any longer, one cold January night he sunk into his domain and headed to the large church at the center, the main room was a large one with a central platform surrounded on all sides by benches above it, bound and gagged in the center were the Dursleys who despite their experiences still glared at him when he entered.
"Even now you are unrepentant, I guess even I cannot redeem everyone," Harry spoke sadly to Petunia, "your one and only chance at redemption and you spet in it's face," he spoke as the demon Lily rose from the floor, "this one performed her duty flawlessly," he spoke while patting her like a pet, "so she get's to take you," he stepped back and 'Lilly' leapt at them sinking her claws into their flesh and dragging them into the floor and down into hot, painfull, silent, darkness.
Harry smiled at the excited Hat who proudly held out his to of the line Nimbus 2000 broom.
With Hagwart's permission Harry sent out some of his minions, running along the shadows they entered every house, three houses only had a handful but the house of snakes had many, in the dark of night they flowed into the dark and into the dreams of certain children.
While Draco Malfoy dreamed of being a poor muggleborn like many of his fellows, Ron Weasley dreamed of being the best and in the spotlight and being utterly alone, Zacharias Smith dreamed of being alone and friendless, and so the demons began working on making them better people.
July rolled around and exams started, stress, excitement, worry, and studying. Harry had little trouble but kept his scores perfectly average, but he was getting bored, as the usual craziness was suppressed by the exams, at a loose end he decided to have a look at the 'forbidden corridor'.
The Cerberus was no problem as it could sense what he was and did the sensible thing, it pretended to be asleep while curled up in a corner as far from him as it could, cute.
Landing in the plant that tried to strangle him he smiled as he took a large part of it into his domain, it would make a great hedge.
The door with keys and giant chessboard he ignored and slipped into the shadows to bypass them, the troll he scared it so badly it fainted and he ignored the riddle and passed through the fire enjoying the burn.
An hour or so later at the behest of his master Quirrell passed through the traps and puzzles, with Dumbledore gone this was his chance, he thought it odd that the cerberus was already asleep, as was the troll, but he wasn't about to pass up good luck like that, his master figured out the riddle and he entered the last room.
Harry pulled the Mirror into his domain, it would be much easier to copy the effect here, as he ran a hand over the surface of it a red colored stone appeared in his pocket, he took a glance at it and tossed it aside forgetting about it, the mirror was much more interesting.
Quirrell looked down at the unconscious Harry potter, it had been simple to stun the boy since he had his back to the entrance, fortunately he had managed to levitate the mirror as the boy had fallen on it and it almost shattered and his master would be very displeased.
he reached down and lifted the boy off it before pulling his hand back as he felt a sudden pain, his master spoke,
"Be careful you fool, his mother's protection still lives in him, it will destroy you if you touch his skin too much, but onto more important things,"
Feeling satisfied at unraveling the secret of the effect, Harry placed the mirror back where it had been, and he then saw in the reflection Quirrell emerge from the flames and aim his wand, he could dodge but might as well play along to find out what was going on.
It didn't take long for him to lose interest in listening to the minion and his parasite (it wasn't a true possession) waffle on and so he stood up.
At his master's warning Quirrell whipped around drawing his wand,
"So, Harry Potter the boy who lived," the parasite spoke, "see what i've become?!"
"An infection," Harry answered,
Voldemort bristled, "KILL HIM!" Quirrell twirled his wand and fired off a bone breaker curse,
Quirrell was still a teacher and under Hogwarts protection, killing him while she still protected him would hurt her, and she was young, naive, and innocent, but as soon as Quirrell gained the intent to kil,l that protection vanished and Harry moved, he could sense that Voldemort was tethered and beyond his influence and so tried to show as little as possible, he moved under the hastily thrown curse, grabbed the professor's hand and did what many little kids would have, he sank his teeth in.
Quirrell screamed in pain as his wand fell to the floor, his fingers turning to ash, and pulled away only for the boy to shove him and he fell on his back only for the boy's hands to grab a handful of his face, it was a quick and underwhelming death leaving behind a set of ash covered robes, and an angry wraith which flew at the boy only for him to move out of the way, Voldemort then fled the castle.
Harry sighed disappointed, that could have been so much more dramatic but it was over too fast, he glanced at the entrance sensing someone coming and didn't feel like answering questions, he moved the mirror of erised to the floor creating a small amount if shadow that he slipped into.
Albus Dumbledore raced into the final room only to find a set of dusty robes, a dusty wand, and the mirror on the floor, he did find a small amount of demonic energy but it was only traces and quite useless, Quirinus Quirrell found himself stood on a large platform and only darkness beyond it, then eyes, so many eyes, and teeth.
Harry Potter attended the end of year feast, all in all he had enjoyed himself and learned a decent amount, hopefully the next year would be as interesting, as he followed the other students to the train he wondered what he would do during the next two months.
