Life was weird at times, very weird and chaotic. That was something that fifteen year old Harry James Potter could tell you. Adding magic to one's life just amplified it many times. So many things had happened to him since he was little, weird things for which he was always blamed for by his relatives. As a child Harry couldn't understand why the Dursley's thought he was at fault for anything strange. It was only when he turned eleven that he had found out the truth.

When Harry was eleven he had received an invitation to a special school called Hogwarts. A school for honest to God MAGIC! The one thing his relatives had always swore didn't exist. At least he now knew why they hated him. Harry was in awe of the magical world but he didn't really like the way people swarmed because he was famous. Being famous for living when his parents hadn't made Harry quite uncomfortable. While at Hogwarts Harry made two friends of his very own and had several small adventures. Harry hadn't expected that at the end of the year he would end up facing his parents murderer and saving a highly prized magical stone that granted immortality and riches beyond man's dreams.

Second year started out just as wild when a House Elf of all beings tried to stop him from going to Hogwarts. It was during a Dueling Class that Harry discovered he possessed a talent widely looked down upon called Parseltongue which allowed him to communicate with snakes and serpents. It with that year that Harry learned how painful it felt to be shunned by other kids for something that wasn't his fault and looked upon with suspicion. Again Harry met his foe, having met another version of Voldemort and fought and killed a basilisk in Salazar Slytherin's hidden Chamber of Secrets.

Third year an insane wizard had escaped from Azkaban supposedly to finish Harry off for destroying his Master. During the year Harry discovered the madman had been best friends with his father and was even Harry's godfather. Never before had Harry felt such sadness, anger and rage. He had wanted Black to find him so he could curse him, possibly even kill him for betraying him and his parents. It wasn't to be though as in the end Sirius Black had been discovered to be innocent and not out to kill Harry but to catch the real culprit.

The real culprit, Peter Pettigrew, had hidden away for nearly thirteen years as a pet rat with the Weasley family. Harry had been able to talk Sirius out of murdering Pettigrew and together they had planned to turn him in to the authorities. Unfortunately a series of unfortunate events occurred beginning with Professor Remus Lupin, a revealed werewolf, forgetting to take his potion which allowed him to keep his mind on the full moon. Savage and unthinking the werewolf had come after them. In the ensuing mess Pettigrew managed to escape and the others were attacked by Dementors, found ammortal beings who sucked out all good and happy memories from their victims. The found beings had almost gotten away with using their greatest, and most terrible ability the Dementors Kiss on Harry and Sirius but were mysteriously driven away.

Later that night Harry had both time traveled with his best friend Hermione, banished over a hundred Dementors with a corporeal patronus in the form of a stag and helped his godfather escape on the back of a hippogryph that had been unjustly sentenced to be executed.

Proving there was no end to his strange luck Harry had been entered into a deadly Tournament to fight his way through the three tasks whilst only being in his fourth year at Hogwarts. In the third task he found himself kidnapped, a fellow student killed and himself used in a ritual to revive Voldemort. It was only through luck and the incompetence of his enemies that Harry escaped. The Minister of Magic, a fool, had denied the return of Voldemort and had all but broke with Dumbledore, who he had previously consulted regularly for advice.

Harry had been banished back to his Muggle relatives and it led to this night. Here he was now fifteen years old facing off against a pair of Dementors after his fat, idiot Muggle cousin had knocked him around a bit.

"Expecto – Expecto Patro – " Harry's head gave a heavy throb throwing off his concentration. He despaired as his wand was knocked from his hand before he was seized by surprisingly strong arms. Harry struggled as the mouth of the Dementor came closer to him. He screamed as the pain in his mind spiked, there was a wrenching sensation before darkness consumed him.

Salazar Ezekiel Slytherin, eldest son of Prium Slytherin and Magdalena Slytherin nee Peverell and eldest child of four. Half-blood wizard born to a Half-blood father and Pureblood mother. A powerful Sorcerer and Master of many magical disciplines. One of four Founders of Hogwarts School of Witchcraft and Wizardry. Husband of two and father of ten. '

Reviled, dark wizard, evil, Dark Lord. This was his legacy, this was how he was remembered.

Lies!

Salazar scowled as he awoke in the body of a fifteen year old wizard over six centuries after he had died.

Time had distorted his history and that of the other Founders greatly. Twisted them into mockeries of themselves. His House was now the House of Evil and Godric's was now known as Light and Noble. Rowena's House was now the House of Nerds and Snobs and Helga's the House of Leftovers and Nobodies. Honestly by modern terms each and every one of his fellows and himself would be called dark wizards and witches. Most modern witches and wizards would never understand the things they had done. Couldn't or wouldn't understand the necessity of their actions. They did not know the life of struggle they lived in the past. Modern witches and wizards were safely hidden from Muggles and had a government to try and protect them.

Salazar shook his head at the foolishness of the future. Of what had become of the Wizarding World. The damned Purebloods were destroying the Wizarding World. Stagnation and corruption was seeping into every corner of their society. They advocated the removal or sometimes outright death of the New Bloods. Salazar himself had a burning hatred of Muggles and had his own issues with the New Bloods but it had largely been blown out of proportion by history.

Salazar felt that his hatred of Muggles was justified. He had only been twenty-two when he returned from Rome with his father to find their family home on fire. The two men had found his twelve year old brother Octavius naked upon their lawn. It was clear even from a distance that he had been tortured. His sweet little brother, who had always loved listening to Salazar's tales or gazing in awe at the magic he willed upon the world. Octavius had been beaten savagely, strangled, emasculated, defecated upon and gutted before he had been left to rot on the ground like garbage. Salazar had been sickened and enraged at sight and his father had been no better.

His mother and younger sisters, ages eleven and seven, had been kidnapped from their home.

It was in the woodlands nearby their home that his father and he had found the remains of their family burned and left to rot in burned out pyres. Salazar's fists clenched in remembered rage and pain. Witches and wizards didn't have the Flame-Freezing Charm back then to keep them safe and their wands had obviously been confiscated. It was only when Salazar and his father moved them to be buried that they had found out all three had been violated before they were killed. Salazar and his father had roared out their hatred, anger and pain before they tracked down the perpetrators.

The duo had tracked them to a nearby village. To their fury those responsible were not only Muggles but also fellow wizards who had wanted what the Slytherin family had. Salazar and his father had not made their end easy or painless. The two enraged wizards had slaughtered the entire village along with their livestock before they burned the village to the ground. They had cursed the ground to never grow fertile crops again, and that any structure built upon the land would decay quicker than natural and at the worst time.

That wasn't the last time Muggles had attacked those that Salazar loved but it was the most heart-wrenching. His father and he had returned to their ruined home and buried the family beneath their blood warded family cemetery. They had gathered what riches and property they still had and had traveled to the keep of Salazar's uncle, Efelstan in modern day Scotland. There Salazar had continued his studies both magical, mundane and martial before leaving to travel the world. His father had never been the same after losing his family and had spent the remainder of his life at his brother's estate.

In his travels Salazar met many people and learned many disciplines both magical and not. He considered no knowledge useless to himself. In the year 987 and 989 respectively Salazar met the man and a woman that would help him forever change the shape of the future of wizard kind in Albion. Godric of the Hollow, as he was known then, was twenty-seven when they met to Salazar's thirty-two. Godric was a half-blood wizard born in what would become known as Godric's Hallow. His father Alferic had been a local Lord and his mother a powerful pureblood witch.

It wasn't until later that Godric had taken up the name Gryffindor when he slew a monstrous griffin that was terrorizing a village, having been driven mad by the death of it's family. The red haired bearded man was a monster of a wizard, both taller than Salazar's own considerable height of six feet and, to borrow a modern phrase, built like a brick shithouse. Godric Gryffindor was a monster with a sword and a wand.

Godric was also loyal, kind to others, courageous and the kind of man who would do almost anything for a friend. Unfortunately Godric also didn't always think things through, was stubborn, brash and loved to fight so much that it often got him into trouble. Salazar couldn't even begin to count the number of brawls and duels the two had participated in because of Godric's brashness. Salazar and Godric had grown very close during their travels. More than friends and closer than brothers.

The woman he had met was of course, Rowena Ravenclaw. A half-blood daughter of New Blood noble father and half-blood mother. It was quickly apparent that Rowena had a vast potential in both intelligence and magic. She had refused her betrothal to a muggle nobleman and had fled her family's keep when she was seventeen. It was then that Salazar and Godric met her. Rowena had been distrustful of the duo at first but they eventually won her over with Salazar personally offering to teach her what he knew of magic.

The three of them had met Helga in 992. Helga had also been a half-blood witch who's parents had been from the Northlands, or Scandinavia as it was known now. They had been farmers who moved to Wales to start a new life and Helga had been born there. They were later killed in a raid when Helga was thirteen leaving her with little magical knowledge but that of Runes and a few cantrips. Helga had managed to escape from their attackers and was later found by a witch named Griselda who made her livelihood as a Healer.

It was Griselda that had taught Helga to read and write and how to identify and gather herbs, plants, liquids and animal products. Griselda taught Helga how to brew and make healing potions, poultices and other concoctions along with her alcohol. It was whilst living with her that Helga found she had a unique bond with animals. Helga was able to understand them and make herself understood to them as well. It was after Griselda's death that Salazar, Rowena and Godric had met her.

For the next five years the foursome traveled together learning and planning their future. It was during these travels that Salazar had met his first wife Marla, a fierce and proud witch from Greece. She had been the most beautiful woman he had ever met and had entranced Salazar at first sight. Marla had been a tall witch possessing long hair the color of amber and eyes as blue as the sea. She had wicked temper but could also be the sweetest woman you had ever met. She was the great love of Salazar's life who brought for joy and light to his existence.

In 995 Salazar's first born son Thalon had been born before he was swiftly followed by his sister Elizabeta a year and a half later. Following her birth Godric had met and married a Scottish witch named Frieda, a red-haired blue eyed lass with a wicked tongue, a quick wit and even faster skill with a wand.

It had become clear in their travels that magical people were in danger and a large portion of the population knew little of magic. They were a danger to themselves and others. Salazar had called together a meeting of the Council of Wizards, a collection of Noble witches and wizards who ruled over those of lesser blood. There Salazar and his friends had argued and gained support to build a school where they could gather magical children together. A school where many students could learn from Masters in safety. To help bring a new stability to their country and spread their knowledge of magic.

They used land gifted to Salazar by his Uncle Efelstan after his passing. The foursome had originally planned to use the keep of his Uncle but quickly found it was too small. Instead they decided to build an entirely new castle while teaching classes in the keep. They begun the construction of Hogwarts in the year 997 with the help of the dwarves and took them nearly seven years to build. Salazar and his friends had gone on to expand the nearby lake, stocking it with plenty of fish for food and even a squid Helga had discovered somewhere and befriended. A colony of Merpeople had been allowed to make their own settlement in the lake in exchange for helping to catch food for the school and to help defend the lake from invaders.

The four of them had also expanded the forest next to the school. They had made the forest into a safe haven for magical creatures with Helga's help alongside several druids. The creatures would have a safe place to live and they would be able to gather ingredients from them for potions, wands and artifacts. Salazar had even brokered a treaty with two clans of centaurs to be allowed to live in the forest in peace in return for them gathering game, herbs, potion ingredients and defending the future students. Masters from around the isles and those near flocked to the school to share their knowledge and to learn from each other.

A village, Helga later named Hogsmeade, sprung up near the school as they offered safety through numbers, power and protective enchantments. The village enjoyed their protection while the school would be provided for by farms in the village. It had provided witches and wizards a safe place to live and barter and to learn about what the Founders were trying to accomplish. The village boomed over the years as magical families moved to the area to allow their children to more easily reach the school.

Salazar had built his Chamber of Secrets, named so by his daughter Elizabeta, underground to hold his most secret and dangerous research safely away from the students. Students were not always wise about what they tried to learn so Salazar hid away what he thought was too dangerous to fall into their hands. In his Chamber he had also made a home for the basilisk, Seleia, that he had bred as an experiment. Salazar had bred her not only for the ingredients he could get from her body but also as protection for the school from any who would threaten it and the precious children within.

Salazar's heart ached at the thought of her death. Unfortunately she had been quite insane in the end. Seleia had always adored children, especially his own, and would have wanted to be killed rather than harm a child no matter their blood. Salazar felt a stab of hatred for Tom Riddle, his descendant who had turned his beloved friend away from her sacred task. Salazar sneered at the thought of Tom Riddle and his quest to finish what he thought was Salazar's dream, his so called noble work. Salazar had never hated New Bloods, had never wanted them dead or excluded from Hogwarts or the Wizarding world. Salazar knew that they were important for the continuation of magic. Their blood renewed the blood of the Old lines and brought new lines into the magical world.

It was true that Salazar had argued with the other Founders over them. Not because he wanted them banned but because Salazar wished for the New Bloods to start their educations separately from the magically raised students. Salazar often found New Bloods to be frightened of themselves, their power, and many times their own relatives. Unless they had the good fortune to be born into Noble families New Bloods were mostly uneducated, illiterate, and unhygienic. They were a great security risk to the school and their fellow students as they had most often been taught to fear and revile magic due to priests. Priests were likely to be the highest authority figure a New Blood would ever meet and religion preached against the evils of magic.

Back then they didn't have Unplottable and Muggle-Repelling Charms. There was nothing stopping the New Bloods from leading others to their safe haven. Salazar had wanted the taken from their Muggle parents and to be adopted into magical families. If not that then for them to at least be educated before being allowed to attend Hogwarts so they were on equal footing. His friends had disagreed. They had thought they had no right to separate a child from their parents.

Salazar's warnings came true as he knew it would, not that even he felt like saying I told you so when it happened. In 1012 a large group of dissatisfied witches and wizards, Muggles, Goblins and Orcs attacked the village of Hogsmeade with the intention of drawing the Founders out for a fight. To the armies detriment they did. Salazar and Godric had lead the charge against them, leaving behind Rowena and Helga to guard the school and the students.

Salazar had known that Godric had a fierce hatred of goblins for killing his parents and younger brother Aflestan. Salazar had only been able to watch as Godric had slaughtered them by the dozen. Godric personally slew the royal family to the last babe and took the sword of King Ragnuk the 1st for his own and later had his name engraved upon it as further insult. Salazar himself, as an insult and security that it wouldn't happen again, had bound the souls and magic of their enemies to the many sets of armor and the statues of Hogwarts. Stripped of their identities they were meant to guard Hogwarts for all time, immortal and unable to pass on. Helga, surprising some with her viciousness, had used their blood and bones to strengthen the protective enchantments and charms around Hogwarts.

Quicker and quicker the memories of his life flashed past his minds eyes along with the memories of Harry James Potter. Memories of the 'Modern' Wizarding World. Memories of Hogwarts and memories of his "descendant" Tom Riddle then Lord Voldemort. Disgust curled in Salazar's gut. Over his nearly three and half centuries of life Salazar Slytherin had battled many would be Dark Lords and Ladies and had battled several true ones. Tom Riddle had nothing on them, a petulant child lashing out of the world. Salazar had battled against ancient horrors, Fae, demons and daemons summoned from the Outer Planes. He had killed more people that Riddle had ever thought about and for reasons history would never know.

Growling Salazar kicked the demon in the chest sending it backwards several feet. Salazar reached out for the link he had always felt. Pulling on it caused a long sword to appear in his hand. Cadfæl. A sword forged for him in a dragon's breath. A sword capable of killing supernatural beings, the undead, demons and daemons.

The blade was made of dark iron, appearing completely black in color aside from the band of gold down the middle engraved with runes more ancient than any had seen in these times. The hilt felt as comfortable in his hand as it ever had. The hilt was a stylized dark green scaled basilisk with yellow diamonds for eyes. The end of the hilt was the tail which was slightly curved where it wrapped around a large dark diamond while it's mouth was opened as if to swallow the blade. Gripping the sword Salazar thrust it into the Dementor in the chest causing it to scream. Normally no mortal blade could touch them and it had arrogantly allowed Salazar to attack it.

"Die vermin!" Salazar hissed, channeling the power of Light into the blade causing white flames to erupt along the blade. The Dementor screeched horribly as it was consumed by the blade. Several motes of glowing light left it's body. Salazar could sense their relief and their gratitude before they disappeared. Salazar's lip curled in distaste. Souls of beings the Dementor had consumed.

The Dementor grew frantic before it shrunk down before Salazar's eyes leaving a dark purple, almost black crystal on the ground. Salazar could sense the miasma coming off it. The Dementor, in a desperate bid to live, had crystallized itself. With the crystal a witch or wizard could summon and control the Dementor. The demon obviously thought Salazar would be greedy and power hungry enough not to pass up a potentially powerful servant.

"Too bad for you demon I don't truck with your kind." Salazar said before he thrust Cadfæl into the crystal breaking it and truly killing the demon. Turning his attention to the other Dementor he saw it attempting to flee with the body of a teenager laying on the ground drooling and staring into the air. Salazar gripped Cadfæl and willed it to change form. Salazar grinned when it became a spear before he threw it through the air. The Dementor wailed as it was impaled and stuck to the wall.

§Who sent you demon?§ Slytherin snarled in Parseltongue. §Tell me swiftly and I will make your end quick.§

§KiLlEr! MuRdeReR oF mY KiN.§ The Dementor rasped.

§That is not what I asked.§ Salazar hissed his eyes narrowed. Channeling a bit of Light into the spear caused the Dementor to screech in pain.

§WItCh! MInIsTrY WItCh! FOuL, lOaThSoMe CrEaTuRe!§ The Dementor hissed. §I WiLl bE aVeNgEd. My BrOtHeRs WilL cOmE fOr YoU fOoLiSh MoRtAl!§

§Not before you are dead.§ Salazar replied before he incinerated the demon.

Concentrating Salazar forced it into crystal form before he killed it. Just like the other Dementor several motes of light escaped from it's body. Salazar caught the one belonging to the Muggle before him and gently coaxed it back towards the boy's living body. With a magic forgotten in this Age Salazar retied the soul to the body of the Muggle causing him to gasp as his consciousness reconnected to his body. The boy screamed before he passed out. Grimacing Salazar found the wand he had dropped before he grabbed the muggle.

Groaning as his smaller than normal body struggled with the weight Salazar cheated by putting a lightening charm on the boy. Salazar sensed that boy didn't have any magic, at least none he could access so Salazar quickly categorized the boy as a Squib. Something he determined by how well the spell worked on the boy. Salazar had felt some resistance but nothing like that of witch or wizard with an active core who were naturally resistant to the magic of others, especially when they felt endangered.

oOoOoOo

Salazar rummaged around the pile of discarded items in his closet. He was doing his best to ignore his anger at Dumbledore and the faint sense of betrayal he got from the revelations that had been revealed to him that night. He hummed as he found what he was looking for. A disc of wood along with a knife and a long thin piece of leather.

Biting his tongue Salazar carefully carved Runes for concealment, protection and obscuring on the disk before he bored a hole through it and slipped the piece of leather through the hole. Salazar grunted as he focused. The magic of this body was crude and upset at the earlier upheaval and not used to the tasks he was using it to perform. Nevertheless Salazar was nothing if not stubborn, talented and powerful. He was a Master of Magic and a servant of the Earth Mother. Salazar channeled his magic through his fingers powering up the Runes. They glowed briefly before settling down. The protective amulet would help protect Salazar's mind until he was able to reestablish mental equilibrium.

An owl flew through the window and alighted on his desk. Reaching for letter tied to it's leg Salazar vaguely recognized it as the crest of the Ministry of Magic. The owl flew back out the window as Salazar broke the seal. Reading Salazar fought the urge to incinerate it.

Dear Mr. Potter,

We have received intelligence that you caused an unknown magical phenomenon at twenty-three minutes past nine this evening in a Muggle-inhabited area and in the presence of a Muggle. The severity of this breach of the Decree for the Reasonable Restriction of Underage Sorcery has resulted in your expulsion from Hogwarts School of Witchcraft and Wizardry. Ministry representatives will be calling at your place of residence shortly to destroy your wand.

As you have already received an official warning for a previous offense under Section 13 of the International Confederation of Wizards' Statute of Secrecy, we regret to inform you that your presence is required at a disciplinary hearing at the Ministry of Magic at 9 a.m. on the twelfth of August.

Hoping you are well,

Yours sincerely,

Mafalda Hopkirk

Like hell! Salazar thought with anger.

He couldn't be arrested. He had too much to do. He needed to sort out his mind. Was he Salazar Ezekiel Slytherin or Harry James Potter or both? Three hundred and twenty-seven year old Master of Magic or fifteen year old teenage Gryffindor? It was irritating and distracting having the memories of two lives. He needed to time to come to terms with what was happening to him.

A/N: I know that this premise has been done before, and done quite well in several stories, but I wanted to add my own to it. This story will have slight crossovers with the television shows of Merlin and BTVS along with other genres.
