Devil in Disguise

Prologue

I do not own Harry Potter or High school DxD

There were once three brothers who were travelling along a lonely, winding road at twilight. In time, the brothers reached a river too deep to wade through and too dangerous to swim across. However, these brothers were learned in the magical arts, and so they simply waved their wands and a bridge appear across the treacherous water. They were halfway across it when they found their way blocked by a hooded figure.

And death spoke to them. He was angry that he had been cheated out of three new victims, for travellers usually drowned in the river. But death was cunning. He pretended to congratulate the three brothers upon their magic, and said that each had earned a prize for having been clever enough to evade him.

So the oldest brother, who was a combative man, asked for a wand more powerful than any in existence: a wand that must always win duels for its owner, a wand worthy of a wizard who had conquered death! So Death crossed to an elder tree on the banks of the river, fashioned a wand from a branch that hung there, and gave it to the oldest brother.

Then the second brother, who was an arrogant man, decided that he wanted to humiliate Death still further, and asked for the power to recall others from Death. So death picked up a stone from the riverbank and gave it to the second brother and told him that the stone would have the power to bring back the dead.

And then Death asked the third and youngest brother what he would like. The youngest brother was the humblest and also the wisest of the brothers, and he did not trust Death. So he asked for something that would enable him to go forth from that place without being followed by Death. And Death, most unwillingly, handed over his own Cloak of Invisibility.

Then Death stood aside and allowed the three brothers to continue on their way and they did so, talking with wonder of the adventure they had had, and admiring Death's gifts.

In due course the brothers separated, each for his own destination.

The first brother travelled on for a week or more, and reaching a distant village, he sought out a fellow wizard with whom he had a quarrel. Naturally, with the Elder Wand as his weapon, he could not fail to win the duel that followed. Leaving his enemy dead upon the floor, the oldest brother proceeded to an inn, where he boasted loudly of the powerful wand he had snatched from Death himself, and of how it made him invincible.

That very night, another wizard crept upon the oldest brother as he lay, wine-sodden, upon his bed. The thief took the wand and, for good measure, slit the oldest brother's throat. And so Death took the first brother for his own.

Meanwhile, the second brother journeyed to his own home, where he lived alone. Here he took out the stone that had the power to recall the dead, and turned it thrice in his hand. To his amazement and his delight, the figure of the girl he had once hoped to marry before her untimely death appeared at once before him.

Yet she was silent and cold, separated from him as through by a veil, though she had returned to the mortal world, she did not truly belong there and suffered. Finally, the second brother, driven mad with hopeless longing, killed himself so as truly to join her. And so Death took the second brother for his own.

But though Death searched for the third brother for many years, he was never able to find him. It was only when he had attained a great age that the youngest brother finally took off the Cloak of Invisibility and gave it to his son. And then he greeted Death as an old friend, and went with him gladly, and, equals, they departed this life.

Many people throughout the world believe that this story is just that, a story. However, there are some that believe it to be true. No matter what believe people believe that would be wrong for the story is real but the story is much older and the three items are something else, something stronger and the items are redemption for one family, the Peverell family.

The Peverell family was once a devil clan form the underworld however during their reign has one of the strongest families and their close ties to the Four Great Satans of old but were thrown from the position and exiled from the underworld for the thefts of the three pieces 'given' by death to the three brothers. The Four Great Satans were angered that someone would steal not one but three artefacts created by the Ophis and the Great Red, they feared that the family would turn on them and try to destroy hierarchy of the underworld and then use that power to great a war that would destroy any remaining devils and turn power over to the heavens. What they didn't know however was by exiling them would be the beginning of a war that wouldn't come for several more centuries, the war would cost the lives of many, many devils but also the lives of the Four Great Satans and God himself. One factor they didn't realise was that the artefacts weren't as powerful as they were made out to be when they are united they only increase the strengths of the user and multiplying their prowess as well as their life.

When the family was exiled to the world above they already knew about some magic but they learnt more and more and knew that the best way for control was to use a wand. The Peverell's entered the political landscape at the time has a minor house however they were experts in combat, sword and wand alike, and had joined in marriage over the years with many higher ranking officials and houses.

They joined with the Houses Potter and Black when they invaded Britain in the name of Julius Caesar and Rome in 55BC. When order had settled in Britain the Houses of Potter, Black and the newly created house of Peverell had managed to control the mundane and the magical people. Their legacies would last until the modern day where the Potters would be befallen to one heir, the house of Black would have a dark legacy attached to the name and the Peverell's would be all but forgotten to many people but a few, mainly Historians and members of the House of Potter where their last true born Peverell would marry into. The house would stay in Britain even after Roman Empire had left but they would still commit troops to the cause of Rome.

When the Pendragon family became the rulers of Britain they had members from the three families attend to the court to help rule the people because the families were still well respected.

The creation of the round table was a the building blocks of the modern magical realm in Britain with thirteen members of the strongest magically families including the Potters, The Blacks, The Peverell's, The Longbottom's, The Bones' and several more. These families were named Most Ancient and Most Nobles Houses and they would create the laws that witches and wizards would follow to allow themselves to be safe from the hands of nobles and peasants alike who would try to harm them just for their gift of magic.

The great clans of the underworld would always remember the house of Peverell but would forget why they were exiled but the one thing they would remember of the exiled family would be that if they managed to collect the artefacts they had sworn to return to the underworld then many families would rush to them to try and gain the power that the name Peverell would gain. But for one family they would be the first to have any advantage from the family for there was a marriage contract between the families that would rewrite any existing contracts written after the fact.

Throughout the years following the round table and the creation of more families the wizards court was established allowing other families to be allowed a say the governing the country and being given titles that would better the position of families such as The Magical House of, Noble House of, Ancient House of, Ancient and Noble House of, Ancient and Most Noble House of, and for the select few families which qualify the title of; The Most Ancient and Most Noble House of. Many of the older families would gain positions within the mundane world as well, the Blacks would gain the title of Viscount Black they would of been given a higher title however they have been known to be a little too violent and many other families had declared that if they gained a higher position they would of incited a civil war within the communities, magical and mundane, the Peverell's would gain the Earl or Count title due to their help towards peace in conflicts within Britain. The Potters would be one of a few families across the globe to gain the title of Duke for their actions in creating not one but two empires and the lengths they go to in order preserve peace and reduce the death toll gain in conquering many countries in order to expand not only the Roman Empire but also later the British Empire.

The education was normally taught between master and apprentice or between family members however in the late 9th century and early 10th century four very gifted magical came together from all other the British isles and from different worlds of life and with different beliefs however, they all shared one thing in common the need to teach children in the magical arts, they were Helga Hufflepuff, Rowena Ravenclaw, Godric Gryffindor and Salazar Slytherin. They built a castle and turned it into a school one that would become famous over time for its knowledge, the fact that it has never fallen into the control of someone who would be able to harm the students ergo the wider British community, and it would also become known for the large amount if pureblood supporters and radicals.

Throughout history many people have come from the Hogwarts and have made become famous for various reasons. Alastor 'Mad eye' Moody has become a famous auror for his feats during Britain's first wizarding war also known has the blood war. Albus Dumbledore became famous for his skill in transfiguration and him defeating Gellert Grindlewald the Dark Lord running around alongside Nazi Germany, a man known in some circles for processing the Elder Wand however when Albus tried to use the wand he realised that the wand Grindlewald used was his original and that he must of hid the Elder Wand somewhere and for some reason.

In 1981 a wizard named the greatest Dark Lord and had declared war and started the Blood War was vanquished by a boy that was only fifteen months old and had been protected by his grandmother who died to save him. When he was defeated the British community hailed the boy a Hero, the boy-who-lived. His parents had arrived shortly after the explosion from the magical backlash had destroyed part of the house in Lancaster. The boy was Neville Longbottom 15 month child saviour.

While many people were celebrating a family in the small village in Godrics Hollow, in Wales, was betrayed by their best friend Peter Pettigrew who had been the secret keeper for the fidelius charm. A team of radicals still intent to see the destruction of the muggles or the mundane's asked him where the family had been staying so the four members of the terrorist organisation known as Death Eaters, Bellatrix, Rudolphus, Rabastian Lestrange and Peter Pettigrew had attacked the House containing James and Lily Potter and would of had their three year old son with them but an old friend of the Potter's had been asked to look after their son just for the night so the boy was out. The team had entered the house but had been quick to engage the couple who, if someone to look at it properly were already waiting for them, it was a hard but quick fight resulting in the death of Peter Pettigrew and Rabastian Lestrange from the Death Eaters and both James and Lily Potter. Their child Hadrian James Potter was left to the care of Zeoticus Gremory, the Head of the House of Gremory, who decided that he would raise him alongside his daughter, Rias Gremory, and would train him to be his daughters future knight if needed as well as help him find the Deathly Hallows, which he already had one in the Potter family Clock of Invisibility.

The tale of three brothers at the start came straight from my copy of 'The Tales of Beedle the Bard'

Rias Gremory will be three years younger than Harry making her the same age as Neville.

I will try to get the first chapter out as soon as possible
