A/N: A story idea that just came to me out of the blue, like most story ideas do, but unlike most, this particular idea stayed around and developed itself beyond a few fight scenes and encounters. With that, I bring to you 'Touched by Chaos', yet another product of my twisted mind! A poll will be up on my profile asking for whether or not I should continue the story or leave it for later as a possible one-off.
Chapter 1- Voices
Harry first heard the voices when he was five. At the time, he had been stricken with a terrible illness, one that left him barely strong enough to feed himself, much less move. However, his guardians, the Dursleys being who they were, had not cared in the slightest, simply locking him in his cupboard under the stairs so that their 'Poor, precious Diddy-kins' did not get infected.
It was in his delirious, starved state that he first heard the whispers. At first he had thought that he was simply hallucinating, the voice simply a figment of his imagination, but it was soon proven to be anything but.
The voice of 'Nurgle', as Harry had learned its name, had whispered to him with a fatherly tone, asking if Harry had liked his gift. When the boy had asked what gift, Nurgle had replied that he was gifted with one of Nurgle's favorite pestilences, one that allowed him to communicate with Harry, despite the worlds between them. While Harry was, at first, horrified, Nurgle had soon explained to him, like a father telling his son about the virtues of vegetables, that the disease was a blessing, not a curse. After all, weren't the survivors of a plague immune to any sort of relapse? Harry would heal, and he would grow stronger as a result. Seeing the logic behind this, a young, five year old Harry Potter soon took to constantly speaking with his friend, who accepted him for what he was, never saying an unkind word to him, never hitting him for slipping up, and giving him a multitude of wondrous gifts! As Harry was stricken with disease after disease, his body grew stronger and more resilient, so that by the time he was six, he was practically immune to any disease!
Four months after Harry had first heard from Nurgle, a second voice appeared in his head. Unlike the fatherly, caring tone of Nurgle, 'Tzeentch' was anything but fatherly, giving the impression of a strict schoolmaster who was kind but firm, quick to discipline any wayward students, but also more than willing to impart knowledge to those willing to learn.
Tzeentch had spoken to young Harry, spinning tales of the wondrous magicks that the boy could be capable, if he was only willing to allow Tzeentch into his heart and soul. The young Harry had immediately accepted, and Tzeentch soon became a presence in his everyday life, just like Nurgle. While Nurgle gifted him with diseases to strengthen his body, Tzeentch taught him magic. He taught Harry how to manipulate minds, how to hurt and even kill anyone with the powers of his mind. It was Tzeentch's influence that caused Harry to take revenge on his abusive guardians, and soon their nights were plagued with terrible nightmares of them being devoured by hundreds of daemons.
Next came Khorne. Khorne first spoke to Harry in the middle of a playground, where a group of older boys had appeared to torment the younger, sickly Harry. Unlike Tzeentch and Nurgle, who had both whispered to Harry, Khorne shouted.
"Will you really let those weaklings continue to dominate you, when you could easily destroy them? Prove to me that you are more than some fool my fellow gods have taken pity on!" Khorne had shouted, startling Harry. However, the God, for that is what Harry knew him to be, spoke truth. Consumed in a terrifying rage, Harry had leaped forward and delivered a terrible blow to one of the bullies' skulls, breaking the older boy's nose and knocking him out. The rest were easy pickings, being knocked out with a plethora of broken limbs and blood flowing freely from wounds where Harry had clawed and bit them. The Dursleys were horrified, and they took the fear out on Harry, locking him away once again, but Harry did not care. He knew he was strong, and that pleasure in his strength called Slaanesh to him.
With a silky voice promising innumerable pleasures, Slaanesh had visited Harry, deeming him worthy of his attentions. With the four gods of Chaos deeming him a worthy individual, Harry threw himself, heart and soul, into his worship of the four. His first sacrifices were animals, brained with rocks or brought in alive as the gods demanded. As rewards for his sacrifices, the gods blessed Harry, Nurgle giving him incredible resilience, Tzeentch revealing secret sorceries that defied even the laws of magic, Khorne granting immense physical prowess, and Slaanesh stimulating him to pleasures unheard of.
Carving the symbols and stars of the gods into his skin, Harry grew from an abused child to a powerful emissary of Chaos, just as was planned.
A nine year old Harry sat in the cupboard, now twisted into something that most mortal minds could not comprehend. In his hand, he held a dagger, an eight pointed star in the weapon's pommel. Harry began to chant, the dagger glowing with forbidden power as it was prepared for tonight's ritual. Tonight was Dudley's birthday, after all, and Harry did not want to disappoint!
His chanting finished, Harry slid the knife into the long sleeve of his shirt, the sacrificial blade ready for use, already thirsting for blood. He waited for the party going on above his head to die down, his cousin's friends eventually leaving the house. It was a pity that their souls couldn't be given over to the gods this day, but a mass disappearance would bring the local law enforcement down on his head, and while he could doubtlessly slaughter them, Tzeentch had ordered him to stay his hand, saying that Harry was to stay undetected for now, the reasons behind his orders unknown to the young disciple of Chaos.
Finally, when only four people remained in the house besides himself, them being Vernon and Petunia, as well as Dudley and his Aunt Marge, Harry slipped out of the locked cupboard, his power easily ripping the cupboard door from its hinges.
His hand clutching tightly on the knife's grip, Harry made his way upstairs, every step slow and deliberate. Finally, he stood before the door to Dudley's room. Without a knock, he entered, the door swinging open at his behest. The room's four occupants stared at him.
"What are you doing up here, freak!" Petunia shouted.
"Why, I simply have a present to give to Dudley, and now that everyone else is gone, I can give it to him!" Harry said cheerfully, a hint of madness in his voice.
"What are you blathering about? Go back to your cupboard, freak!" Vernon shouted, his face red from alcohol.
"I will, but first I wish to give you all my gift!" Harry said, before drawing his knife with a flick of his wrist and starting to laugh. At first, his laugh was that of a nine year old child, happy and without a care in the world, but it soon grew dark, deranged, as if a mad god was standing there in Harry's place. A wave of his empty hand closed all exits, leaving his foster family trapped in the room with him. Sensing its impending use, the knife began to shriek in anticipation, the noise otherworldly and terrifying. Dudley screamed in response, the entire family shrinking back as Harry advanced on them, screaming knife in hand. However, rather than stab them all then and there, Harry delivered four powerful blows with the pommel of the weapon, the mere touch of the cursed knife sending his victims into a nightmare filled sleep.
Dragging their unconscious bodies down to his cupboard, which had been significantly expanded by Harry's sorcery, Harry laid the four bodies across four altars, binding them there with powerful chains which had been provided for him by Tzeentch and Khorne.
Knife in hand, Harry willed for the four sacrifices to wake. Every god save Nurgle had claimed one of their souls as their own, Nurgle abstaining as he simply cared for Harry for who he was, not for the sacrifices he brought. The four Dursleys woke screaming, and continued to scream as they realized where they were, their eyes drawn to the giant, eight pointed star painted in what looked like blood on the ceiling. Harry laughed as his foster family screamed, the light and childish peals of laughter contrasting sharply with the screams of terror from his victims.
"You should all feel honored! The Chaos gods have asked for your souls specifically, and I intend to provide for them!" Harry laughed as he walked over to Vernon.
"You freak! Once I get out of here, I'm calling the police to take you to jail where you belong!" Vernon shouted.
"You have some fight in you! I see why Khorne wanted your soul! YOUR BLOOD SHALL PLEASE KHORNE!" Harry shouted, before stabbing the knife, which glowed with a blood-red light, deep into Vernon's chest before reaching into the open wound and ripping his heart out, crushing the organ with his bare hand and sending blood all over the room. Then, with a second cut, Harry removed Vernon's head, the flesh burning away in a burst of blue fire. The smell of fire and brimstone filled the air.
"BLOOD FOR THE BLOOD GOD! SKULLS FOR THE SKULL THRONE OF KHORNE!" Harry shouted as he held the skull aloft in his bloodstained hands, Vernon's headless corpse releasing a seemingly infinite torrent of blood behind him. Putting the skull down, Harry moved on to Petunia, who was shaking in fear, having just seen her husband slaughtered like an animal in front of her.
"Petunia, Tzeentch has expressed an interest in the faint magic in your blood. He wishes to study you! You should be elated at the opportunity!" Harry cackled, before driving the knife, which now glowed a blinding blue, into his aunt's chest. Petunia's skin began to bubble and shift, its owner screaming in agony, her body slowly tearing itself apart. Finally, after what could have been either an eternity or an instant, Harry withdrew the knife, Petunia's body burning away in a plume of azure fire.
Harry laughed as he walked over to Marge, who had frozen in terror, eyes shut tight.
"Margie! Grandfather Nurgle wants to share his gifts with you! He loves you very much, just like he loves me! Come and join him!" Harry said, his childish voice carrying no malice, rather, it contained only happiness... and a terrible madness. Jabbing the now green knife into her chest, he watched with childish anticipation as Marge's body rapidly decayed in front of him, a most foul stench filling the room, mixing with the scent of brimstone and magic. Finally, when even her bones had crumbled to dust, Harry picked up the knife and walked over to Dudley, who was bawling his eyes out at the scene before him.
"Cousin Dudley, Slaanesh wishes to meet you! He promised me infinite pleasures if only I deliver you to him, and I'll do just that! Who knows, maybe he'll even give you some of his gifts!" Harry said, before laughing once again as he plunged the now pink knife into Dudley's chest.
Dudley's last few seconds were spent alternating between extremes of pain and pleasure, his body giving out from the sheer strain of the shifting sensations. With his sacrifice completed, Harry turned to the center of the room, where a portal had begun to open. As the rip in reality yawned wide before him, Harry caught his first true glimpse of the warp... and it was beautiful. Ever shifting, arranging itself into countless impossible patterns, the Warp beckoned to him. Harry walked up to it, stopping at the brink of the abyss. Gazing into the beautiful sight before him, Harry felt the presence of his four gods strengthen within his soul. Then, the energies of the warp poured forth, consuming Harry and granting him the blessing of his four patron deities, the power surging through him making the boons previously granted to him seem pitiful by comparison.
Nurgle's gift came first, the plaguefather's power granting him a resilience against all physical harm, making him nearly impossible to kill through physical means. Thousands of pockets of disease and poison formed just below the boy's skin, the diseases within lying dormant, waiting to be unleashed upon the world.
Next came Tzeentch's gift, a surge of both power and knowledge unlike any Harry had felt before. He felt his magical potential increase exponentially, while his skin built up an incredible resistance to the same magic. Finally, immense amounts of knowledge had appeared in Harry's head, giving him both the raw power and the knowledge to bring ruin to entire nations with ease.
Khorne's gift followed, the blood god not wishing to be outdone by his brethren. Immense physical strength and combat instinct was transferred over. Harry could now fight with near any weapon, and could easily lift ten times his weight without breaking a sweat.
Finally, Slaanesh came forth. Rather than the other three gods, who gave their gifts with a detached interest, Slaanesh's avatar, a fraction of the god's true power, embraced Harry, causing pleasures to shoot through his body. When the god of pleasure finally let go, Harry was changed. Where before he looked like a starved, gaunt child, Harry was now beautiful. Silky black hair fell to his shoulders, while his brilliant green eyes were like jewels set in skin of pure white ivory. His facial features were now arranged perfectly, and his musculature showed throughout his now healthy body.
Unknown to Harry, Slaanesh had used the opportunity to devour the parasite he had noticed leeching off of Harry's own soul. After all, he couldn't have his key to this world weakened by some pathetic mortal's feeble attempts at holding on to life now, could he?
With Voldemort's soul fragment gone, the scar on Harry's forehead vanished, replaced by a thinly traced eight pointed star. It was the star of Chaos Undivided. The gods had acknowledged Harry Potter as their champion in this world, and Harry did not intend to disappoint.
Chuckling with glee at his newfound gifts, Harry watched as the portal to the Warp closed, severing his most intimate contact with the Chaos gods, leaving them, once again, as voices in his mind.
The next two years passed with Harry learning to master his newfound power. When people came to investigate the Dursleys' disappearances, they disappeared as well, sacrificed without a hint of their demise reaching the outside world. The house quickly gained a reputation as being haunted, and during the Halloween of Harry's tenth year of life, several kids, mostly friends of Dudley, had entered on a dare. Harry had sacrificed them to his gods as well, although he let their screams sound out beyond the confines of the house. As his eleventh birthday drew ever closer, Harry had summoned his first Daemon, a Nurgling. He smiled as the little pustule scampered around his house, laughing as the tiny effigy of Nurgle groaned, vomiting all over the now tainted floor. Then, exactly one week before his birthday, an owl dropped a letter into the house's mail slot.
Sensing Tzeentch's urge to read it, Harry picked it up. It was addressed:
Mr. H. Potter.
4. Privet Drive,
Little Whingig,
Surrey.
Opening the letter, Harry read the contents to himself:

Harry read the supply list twice over, committing it to memory.
"Yes, you are to go to this school, Champion, for it is there that you will reach your next stage in terms of usefulness..." Tzeentch's voice whispered in his head.
'Were you already aware of this?' Harry asked.
"Of course I was, fool! I am Tzeentch, the Lord of Sorcery, the knower of all things! Of course I knew that this would happen! Now, the supplies can be easily provided. I can provide the robes and *sigh* the pointed hat, and Khorne can easily provide the gloves. I am sure Nurgle would be happy to give you one of his spare cauldrons and some phials, and the rest can easily be purchased. Now, you are to send the reply back immediately, to be written as follows:
To Whomever it May Concern
I, Harry James Potter, sincerely accept your invitation to the Hogwarts School of Witchcraft and Wizardry. I shall have obtained the pre-requisite supplies by the time you receive this letter, and will look forward to a memorable experience at Hogwarts.
Sincerely,
Harry James Potter."
Harry finished writing the letter, following Tzeentch's instructions to the letter. Then, after folding the weapon into an envelope, he threw it out of the window, casting a compulsion on the owl to take the letter back to its master. Putting on a new set of clothes, Harry walked out of the house, following Tzeentch's guidance. As if he was nothing more than a human puppet, Harry slowly walked all the way to an old looking pub, the Leaky Cauldron. He opened the door, his supernatural beauty drawing the eyes of everyone in the pub, female and otherwise. Ignoring the looks cast in his direction, Harry walked into the back room, before taking his finger and tapping a set of bricks in a sequence. The wall slid out, and Harry walked on, still following his god's will. Proceeding onward to a large bank, Gringotts, Harry entered. As soon as he did, all activity inside the bank ground to a halt.
Harry walked up to one of the desks, aware of every eye in the massive building fixed on him. The humans looked at him in wonder, and sometimes in lust, as they noticed his physical appearance. The goblins though... they had naked fear in their eyes.
"Hello! My name is Harry James Potter, and I wish to make a withdrawal from my family vault." Harry said, his voice cheerful.
"I- I would need proof that you are indeed Harry Potter before you can make any alterations to the vault's contents. A small amount of blood should be sufficient." The goblin replied, trying hard not to break and flee from the abomination he sensed standing before him.
Drawing his old sacrificial dagger, Harry pricked the tip of his finger, causing a single drop of blood to fall into an indicated receptacle, the drop landing on a special magic analyzer, which reported that Harry was indeed himself. Unknown to the goblin that analyzed the blood, said blood contained a particularly virulent strain of Goblin Pox, which would be the start of an immense epidemic that would rage unimpeded throughout the goblin population several years later, killing thousands in Nurgle's name.
Harry followed the now 'gifted' goblin into a cart, where he was then taken for a rather exciting ride through a tunnel network, eventually finding himself at the Potter vault. A simple insert of a key, and the vault opened.
"Thank you, Mister Goblin!" Harry said, his voice delighted as he beheld the piles of gold in front of him, the sight of the shining metal mountains being more than enough to stimulate the greed of Slaanesh. Packing as much of the precious gold away, Harry returned to the goblin, the vault shutting behind him.
"This security is simply dreadful! You should really ensure that your valuables are more secure, Harry! I'm thinking a few Daemonettes here, maybe a Daemon Engine there, and Presto! No thieves shall ever touch your golden horde!"
The voice of Slaanesh sounded in his head.
'I was thinking the same thing uncle neshie!' Harry thought back. Slaanesh, being the youngest of the four gods, as well as the god of pleasure, was much less formal with Harry, just like 'Papa Nurgle'.
Harry ordered the goblin to re-open the door. Once the door was opened, Harry began to chant, his magic quickly pulling twisted, hellish metal from the depths of the warp, the metal forming together into a giant, bipedal metal monstrosity. The goblin in the cart practically pissed himself in fear as the Hellslicer claws of the Slaanesh Subjugator attached themselves to the sides of the massive Daemon engine. Finally, a pair of Tormentor cannons and a set of sonic weapons were attached to the metal monster, completing the empty shell. Then, Harry began to chant again, this time opening a rip in reality through which a host of Daemons came through, the Slaaneshi Daemons entering the Daemon engine and being bound inside of it. With the metal guardian complete, Harry closed the vault door and told the petrified goblin to take him out, all with a happy, childish smile on his face.
Once he was out of the bank, Tzeentch's guidance suddenly withdrew from his mind, leaving behind a parting measure.
"I will now leave you to your own devices. A word of advice, I suggest perusing Knockturn Alley for rare reagents and artifacts, as well as obtaining some... exotic reagents for your wand, as the mundane twigs they call wands here will be worthless to you. You are to direct any request for funds to Slaanesh." Tzeentch said, before falling silent, no doubt off to go planning somewhere.
Taking Tzeentch's advice, Harry headed off towards Knockturn alley, his senses scanning for the warp presence of powerful artifacts. He wasn't disappointed, as he almost immediately picked up the warp signature of a Daemon weapon somewhere within the maze of passageways that was Knockturn alley. While it wasn't a particularly strong signature, indicating that it was likely only containing a lesser Daemon, but it was still leagues ahead of anything that the walking jokes that seemed to call themselves wizards on his world could produce. After a few minutes of running, he finally found his quarry, located inside a dinghy shop.
He walked inside, scanning the inside of the shop. A star of Chaos emblazoned on a piece of parchment, which was in turn posted on a wall near the back of the shop, caught his eye. Picking up the daemonic spear, a weapon that Harry recognized as an Ether Lance, a weapon that could either fire powerful bolts of warp energy or draw its victims into itself, using their souls to power itself.
A wizard chose that moment to walk out of the back room, noticing that he had a customer. At first he adopted a look of bored disinterest, but as Harry drew closer, Ether Lance in hand, the man spotted the eight pointed star emblazoned on the green eyed boy's head.
"It's been a while since I've seen that symbol, young man. In fact, I'm still trying to decipher what it means! I don't suppose you would know what it means, now would you? My family has been collecting artifacts with that mark on them for generations, and we still know nothing about what made them! Strange things, they are, I could have sworn I heard that one sword whisper..." The man trailed off as Harry walked behind the counter, green eyes blazing with excitement and a hand gripping his sacrificial knife tightly.
"It is the symbol of Chaos!" Harry said, a smile on his face. "I'm sure you want to know all about it, but first..." Harry drew the knife, the weapon already screaming. "...It's time for a sacrifice! For Chaos!" Harry giggled, before kicking the man down, his scream silenced by a hand clapping down across his mouth. Before the man had a chance to struggle, the knife plunged down, slicing into the man's chest.
"I wonder what god you're going to appease!" Harry said, before the man's body began to morph and bubble, before finally vanishing in a burst of blue fire. "Tzeentch it is then!" He exclaimed, before withdrawing the knife, placing it back into the hidden sheath on his wrist. "I guess everything in this store is mine now! I wonder what else there is here." Harry said, before remembering that he had nowhere to put his newfound loot. After a short pout, he suddenly remembered that there was a store selling specialized trunks that could contain entire rooms or even houses inside of themselves.
Placing down the Ether Lance to act as a beacon to allow him to return to the now vacant store, Harry sprinted out of the store, sprinting all the way to Madame Volumin's Magical Trunks. Entering the shop, he walked up to the desk, a cheerful smile on his face, as if he hadn't killed someone in cold blood less than ten minutes before.
"I would like a trunk!" He said in an upbeat voice.
"Oh? What kind?" The old woman minding the store asked, a smile on her face. The young tykes these days, so innocent and full of cheer!
"Sixteen rooms, plenty of storage space, at least one large, circular room for spell experimentation, a library, a well vented room for alchemical experiments, oh, and a full bathroom please. Leave all the other rooms empty, please!" Harry ordered, speaking rapidly.
"Very well. Any preferences to external appearance?"
"No, I will decorate it myself, but thank you for asking!" Harry said. Best be courteous with future sacrifices, after all, it makes it so much easier to gift them to the dark gods.
It was several minutes before the order was done, a much younger assistant, one who couldn't have been older than nineteen or twenty, walked out carrying the trunk. She froze as she caught sight of Harry. Then, putting down the trunk, she rushed over to him, having been caught in the allure of Slaanesh.
"HE'S SO CUUUUUTE!" The girl squealed. That was unexpected. Within seconds of the girl's shout, Harry had been swept off his feet and was being cradled to the older girl's chest as she rocked him back and forth. He was dimly aware of Slaanesh laughing his/her ass off in his realm of the warp.
Eventually, he managed to struggle his way out of the girl's iron grip, grab his trunk, and run out of the store, trunk held high over his head, as he sprinted towards the store dealing in Chaos artifacts. Harry knew that the Warp linked multiple realms, and that artifacts might cross over from one realm to another, but to find such a large concentration of said Chaos artifacts was most fortuitous.
Entering the store, he let the looting instinct of his Slaaneshi aspect of Greed take over, and he quickly and efficiently packed everything that wasn't bolted down, and quite a few things that were, into his trunk. Finally, when there was not a single warp signature remaining, Harry decided that now was a good time to acquire the necessary reagents for a wand suitable for a champion of Chaos. Using sorcery to blacken the glass of the storefront, Harry prepared to summon a host of four daemons. The first daemon to be summoned was a Khornate Bloodletter. The red, horned Daemon looked about to charge, but stopped when Harry spoke.
"Daemon of mighty Khorne! I challenge you to single combat!" Harry said, voice serious. Pulling a Dreadaxe, a powerful axe instilled with a thirst for the souls of other daemons, from its place near the top of the trunk.
The bloodletter roared its acceptance, waiting to allow Harry to ready his weapon. Then, at an unspoken command, both combatants charged. Blocking the daemon's first blow, Harry roared in anger, allowing the bloodlust of Khorne to take him over. The fight lasted for less than a minute, but during that time the two contestants had blocked and dodged over a hundred blows each. Finally, Harry's axe found purchase in the bloodletter's side, causing the daemon to fall to the ground, bested. Pulling out a vial that he had found lying around in the back of the store, Harry quickly bent over the rend in the bloodletter's side, quickly filling the vial with the bright, burning blood of the Khornate Daemon. Then, as soon as Harry had finished his task, the rest of the Daemon vanished, leaving only its Hellblade and Collar of Khorne behind. Grabbing both of the daemonic items, Harry prepared to summon his next Daemon.
The next daemon to be summoned was a Nutglite Plaguebearer. This time, rather than undergo a trial by combat, Harry decided to simply ask politely for what he wanted.
"Say, Mr. Plaguebearer, do you have a small amount of small intestine you could possibly spare? I would really appreciate if you could please give me about a foot of intestine, Mr. Plaguebearer." Harry said.
"Sure thing, kiddo!" The plaguebearer spoke with the jovial, fatherly voice of Nurgle, which belied its form as a bloated, diseased human. Nurglite daemons were always easy to deal with, once you built up a resistance to the millions of plagues that called their bodies home. This particular plaguebearer then looked down, and with a single, messy swipe of its plaguesword, sliced off about three or so feet of small intestine.
"Keep the change, kiddo." The jolly daemon said, before returning to the immaterium, allowing Harry to summon the next Daemon, this one being a daemonette of Slaanesh. The crab clawed female daemon wore a sultry grin as she materialized.
"Well, well, well... What do we have here, handsome?" The daemonette said in a low, husky voice.
"Nothing much. I'd just like some of your hair. Reagents and all." Harry replied, once again keeping his voice serious.
"Oh really now... I might be able to provide that, but it comes at a price~! You see, it's been a while since I've had some decent action, if ya know what I mean, and I would appreciate it if you could, ya know... scratch that itch of mine. Who knows, I might even scratch back!" The Daemonette purred.
Sighing, Harry dropped his pants. It wasn't the first time he had made deals of this kind with Daemonettes, so he might as well get it over with.
{This lemon has been lost in the Warp. It will likely never return.}
Almost 2 hours later, Harry finally had the reagent he had summoned the rather... energetic Daemonette for. A lock of Daemonette hair rested nearby, right next to a stinking length of intestine and a vial of perpetually boiling blood.
Then, he summoned the final daemon, raising his Dreadaxe as the flamer of Tzeentch came through. The flamer was not a sentient daemon, so Harry simply chopped it as it materialized, before bottling some of the perpetually burning ichor that leaked from the lesser Daemon's wound.
With all the reagents gathered, he got to work. Quickly mixing the blood and ichor together, he put the Daemonette hair in to soak in the resulting liquid. Finally, he poured the result into the Plaguebearer intestine, which had recently been sown shut with a portion of daemonette hair. Severing the length that he did not need, Harry sewed the remaining side of intestine shut, before using sorcery to dry and shrink the result, which ended up as a thin, shriveled length of Chaos essence. The perfect core for a Chaos wand.
Finding a small tree out in front of the store, Harry yanked it out of the ground before opening a portal to the Warp, shoving the tree into the swirling portal. The tree twisted and groaned under the stress, before Harry finally judged that it was mutated enough and pulled it out. He then took his Dreadaxe and severed any un-mutated bits, before carving out a suitable hunk of warped wood for wandmaking, before cheerfully skipping down towards Ollivander's.
Reaching the wandmaker's store, Harry entered without knocking, the bell above the door announcing his entrance. Sensing the shop owner's presence behind a line of nearby shelves, Harry called out loudly:
"I'm looking to have a custom wand made! I have all the materials provided, I just need someone to put it together!" Harry said, just as Ollivander came out from behind a corner.
"A custom wand, you say? Interesting, it has certainly been a while since I have made one of those. Why do you want a wand custom made, though? I am certain that there is a wand suitable for you somewhere here. What is your name, young man?" Ollivander asked.
"Oh, I'm Harry Potter! I want a custom wand because I don't think there is a wand good for me here. If you can prove me wrong though, I'll share with you how I got these reagents." Harry said.
"Oh? Very well then." The wand maker said, taking a critical look at his customer, before pulling out a wand from one of the shelves.
"Yew and Dragon Heartstring, a rather supple wand. Give it a wave, will you?" The man said, handing Harry the wand. A quick flick of his wrist, and the wand exploded like a firecracker, its mundane magical core unable to take the strain, sending shards of wood all over the shop.
"I see... Let's try this one, shall we? Ash with unicorn hair." The result was the same, an explosion.
"Definitely not that one, I see. Try this one. Holly and Phoenix Feather, an unusual combination, but one I think might suit you." As Harry waved it, it seemed to release a faint trail of multicolored sparks for a moment, before it too exploded.
"I see. Very well then, Mr. Potter, I shall have this wand done by this time tomorrow. I must confess, though, this is a rather... interesting core." Ollivander said, examining the Daemon gut wrapped materials.
"I know!" Harry said, "I'll see you later!"
Harry left the shop, leaving an old wandmaker to his work.
The rest of the shopping trip went by fairly quickly, with minimal sacrifices, Harry returned home to find the already Chaos infested house full of even more gifts for him. Tzeentch had indeed provided him with clothing, the black robes coated with hundreds of Chaos runes, promising protection against almost every magic, as well as from many physical attacks. The cauldron was provided by Nurgle, being a tiny copy of his Cauldron of Pestilence, with but a fraction of the power. The ensemble was completed by a set of black leather armor provided by Khorne, to be worn over the robes for additional protection, and jewelry from Slaanesh, with gems in the form of all the different marks and stars of the Chaos gods, as well as the star of Chaos Undivided. Each was designed to give its wearer the blessing of its respective Chaos God. When he asked Slaanesh why he needed them for each individual god when he already had the Undivided necklace, Slaanesh had replied that it was a plan of Tzeentch to make them, which would be revealed in time.
Smiling at his new gifts, Harry went to sleep, ready to play a further part in his gods' plans the next day.
A/N: I know the Chaos Gods, specifically Tzeentch and Slaanesh, are acting WAAAAAY OOC, which is all according to plan. Khorne will be a bloodthirsty berserker, Tzeentch will be a stern but friendly teacher, Nurgle will be the big, kind, disease riddled grandfather, and Slaanesh will be the perverted but well meaning uncle.
More specifically, those are the personas that they will show to Harry. After all, children can be easily manipulated with a friendly face, so the gods take up friendlier personas to more easily manipulate him, until he no longer cares what his masters act like, upon which they reveal their true nature. In the cases of Nurgle and Khorne, it shouldn't change much, but Slaanesh, and even more so, Tzeentch, are to some extent using a false persona to manipulate Harry.
I'll soon have a poll up on my profile to ask you whether I should continue this story or not.
