III: A rather dedicated introduction part 3 (Harry Potter Year 5)

(Summer before 5th Year)

Harry sat in the Black Library, up to his knees in books. The table had been extended and widened and using a set of tiered bookstands, several very heavy and ancient tomes of the Potter family sat in front of him. There were three reoccurring words: Bandrui, Tuatha de Danann and Comhnoir. There was also a reference to something known as the Britannia Matter.

"Ddraig? You know anything about this Britannia Matter? What is a Comhnoir? What are the Bandrui and the Tuatha de Danann?"

"The Britannia Matter, is a reference back to the initial war. A Comhnoir, I believe is Irish Gaelic for Guardian or Custodian. Bandrui are…druids of a kind who follow the Gods of Ire and Scotland whom are collectively known as the Tuatha de Danann. Why?"

Harry's eyes widened "What war, Ddraig? What were my family mixed up in? Is that the reason why throughout history whenever my family has a large group of us; misfortune comes to us?"

Ddraig sighed "Okay…I'm a talking gauntlet that can morph into a suit of armour right. Anyway, I am a fragment of a much larger entity known as the Red Dragon Emperor, you might be familiar with the title 'Welsh Dragon' or even 'Y Ddraig Goch'? Yes, I'm the Red Dragon of Wales. Anyway, my father if you could call him that is the Red Dragon Emperor of Domination. He and my…Uncle, you could say is Gwiber or the White Dragon Emperor or even the Vanishing Dragon…Their power is immense and so destructive to the point when we were fighting near, this planet; the Angelic Host of Heaven, the Fallen Legion and the 72 Devil Pillars who were fighting each other and the native pantheons of Earth…They all joined forces and with great loss on their part sealed Father and Albion away, during the fight I was born and hid in what is now Wales. So yes, my friend, Angels, Fallen Angels and Devils exist as did other pantheons…Basically the Britannia Matter were the five or six pantheons of Britain banding together to give all three factions a proper good kicking. They lost, but they didn't go quietly. Anyway, they made a family the Custodian or Guardian of the armoury, yours. You, Hadrian son of James possess and wield a veritable arsenal of artefacts known as Ancient Gears designed to kickass, take names and generally fuck with the new religions."

Harry closed the books with a thud "You're going to have to go into more detail about these Gears…I take it you yourself are a powerful one?"

"Somewhat…I'm not as powerful as the 13…think of them as like the Unforgivable Curses. No where near as powerful as them, but I'm not a pushover. I am still gaining power, but in the future, I could contend with the 13."

"I'm going to need to step up my training?" All he got in reply was an ominous chuckle.Harry sighed his training had kicked up a gear. After receiving a summons in an attempt to guilt trip Harry into falling into Dumbledore's thumb again. This would have meant Harry ran into an unfortunate encounter with Delores Umbridge which would have escalated further throughout his fifth year.

However, due to Sirius's intervention and him catching Harry reading through some of the darker tomes in the Black Library.

(Flashback)

"Why are you reading this?" Sirius asked out of curiosity and slight worry.

"Something that's been annoying me since Second Year."

"When the…"

"Aye."

"What does the Ancient Dragon have to say on the matter?" Sirius, Remus and Hermione were the only ones who knew about the Gauntlet that resided in Harry's arm.

"Said they're something known as a Phylactery. Never heard of the term…"

Sirius paled "It's also known as Horcrux…One moment." With that Sirius vanished into the labyrinth of the Black Library, there was cursing and swearing and a colossal crash. Sirius eventually returned, Hermione had come clattering into the Library, she had been in an Arithmancy study when she heard the crashes and a concerned Arithmancy Teacher followed as well.

"Found it…Funny, it's literally labelled 'Arts Most Foul', I can see why. Anyway, Horcruxes in essence give off a weird signal and taint. No matter what is used organic or inorganic objects they are never the same. However, using a former or current container for a Horcrux, using a clever little bit of Runes, Arithmancy, a ritual or two; someone, Us, can divine and theoretically track down Horcruxes."

"We have a contract, Mr. Black. Whatever happens in this contract is confidential, but I will say that I am interested in tracking down these Horcruxes." The Lecturer said.

(End Flashback)

The rest of the summer, Harry, Hermione, Sirius and the Tutors much to Dumbledore's disappointment and chagrin despite Sirius allowing Dumbledore to host his Resistance at the Black Family home; the Head of the House had put his foot down about any sort of cleaning out of the books.

They realised that Harry and the Diary had both been Horcruxes, and with a simple triangulation equation with two parts being former Horcruxes, the remaining five horcruxes pinged up. The distance between them distorted the shape of the object: An ornate Locket was here in the Black House; a Chalice in the Lestrange Vault; a Diadem somewhere and a Ring.

"DOBBY! KREACHER!" The two House Elves appeared in a small pile of blurred and flailing body parts. Eventually the two had orders to scour the house to find a golden ornate locket. It was returned and in a flash of emerald green light and a deafening shriek, which caught several people in the Order off guard.

"Sirius, my boy…" Called Dumbledore as he walked out of the dining room, his orange and turquoise butterfly robes a flutter.

"Horcrux, Professor Dumbledore. He created Horcruxes." The only saving grace was that Snape was not present at the meeting; as Dumbledore's eyes hardened.

"Sirius, I forbid you…"

Harry reacted his wand was in hand and as Dumbledore drew his wand Harry was already casting, Sirius was also drawing his wand in the process. Harry's disarming charm took the wand clean out of his Headmaster's hand, it bounced off the wall and landed squarely in his hand. Suddenly a warmth flooded through him. "I see, this explains much…" Dumbledore said, his eyes now brightening slightly "…My friends, colleagues both new and old; those who remember the previous war and those who have joined this one for whatever reason with this unforeseen change in circumstance I have a new plan. It pains this old heart of mine but we can allow no quarter; alive is the main objective. Those who have knowledge of the more interesting arts of magic please remain here, everyone else keep an eye and ear open for a sympathetic listener who might assist us either openly or from the shadows." With that he twirled on his heel and left; he had a meeting to have and with some old friends.

Moody grinned "Now we're getting somewhere…Now then, Black…what's this about Horcruxes?"

Sirius explained and the tension that gathered in the few remaining veterans nodded. They had a game plan, they had information and were now going to enact it. For the cup in the Lestrange Vault, kill the Lestrange Brothers, Sirius dissolves Bellatrix's marriage and he claims ownership.

Dumbledore appeared with a soft pop, since Voldemort's fall he had been investigating and re-visiting his past and some of the more darker paths of magic. All in the attempt of trying to unpuzzle the puzzle that was now a construct of Tom Riddle. Dumbledore scoffed to himself as he appeared near the Gaunt Family shack…How such a noble family had fallen so low baffled Dumbledore.

He wasn't as good or noble as everyone thought he was. He, Albus Percival Wulfric Brian Dumbledore was a flawed, ideological, idiosyncratic pacifist; one who held power for change but did nothing to do so. It was true, he could see the writing on the wall the pureblood supremacy was no longer a fact it was a rapidly fading dream. In his time at Hogwarts, it was slightly evident with one Hector Granger not a wizard known for his combat skills but recognised for his bushy brown hair almost prodigious skill in potions and a possessor of a much sharper wit. Something that was blatantly obvious in his descendent Hermione Granger.

As he reigned as a teacher and then Headmaster over Hogwarts, he watched as more and more half-bloods and muggleborns reach into the upper percentages of overall academic success. Most of the scarce new developments were actually done by Muggleborns and Halfbloods, however they had been shunned and shut down by proud, zealotry and bigotry of the still overruling Purebloods.

He brought the wards down with ease; before he had been forced to take on the Headship of the Dumbledore Family, he wanted to be a Rune Warder. He had wanted to be many things, and desired even more, but for now he wanted to be known for something…something great! Something noble. As he brought the wards down, he activated a seal. A bright green circle with a unique sigil appeared, soon enough a tall, green haired, blue eyed impeccably dressed young man appeared; the only evidence of him not being human aside from the fact he came out of the ground and he possessed a set of batlike wings.

"Albus."

"Maou Adjuka, the time has come for me to use the last of the seven favours as agreed upon."

Adjuka Beelzebub, formerly Adjuka Astaroth one former aces of the Anti-Satan Faction and contender for the Heirship of the Astaroth family before being nominated to Satan Beelzebub nodded. He had been very young when he and his three best friends Sirzechs Gremory, Serafall Sitri and Falbium Glasya-Labolas or rather two best friends and the girl and later woman he had a crush on had participated in what was known as the 'Hellish Revolution' which resulted in the downfall of five of the 72 Pillar Families with 31 of the Families being annihilated in the Three Faction War that had robbed the Devils of their four leaders the original Lucifer, Beelzebub, Asmodeus and Leviathan. They, the four young aces, had forsaken all family names and inheritances and took up the mantles of the Four Satans respectively. It had been a close call between Ajuka and Sirzechs for the mantle of Lucifer in terms of power but in terms of charming and motivating the people Sirzechs was definitely the superior one of them. Adjuka grinned, he wouldn't have become a Satan if wasn't for Sirzechs.

"Aye, Albus it has. What is it?"

"Ways to track, divine, find and destroy Horcruxes and ways to leave a lasting legacy."

Adjuka nodded "Horcruxes, give me two days and I'll have something for you. Although, it will take a chunk of your life force or energy from a Sacred Gear…Shall we? As for your legacy, You're Headmaster of a School of Magic that is part of a much larger overarching agreement of neutrality, it is supposed to be the Premier School at that. You want to be remembered, do something about it. I got up and fought for a new leadership in Hell, now look at me, and now I'm one of the four Maou."

Dumbledore and the Satan King entered the wards; rather the Devil King casually brought the wards down and Dumbledore watched in amazement. Ajuka calmly opened the floor and removed the cursed ring box and the rings on it, they to saw the skeletal hands "Give this to the Lion's Strongest and the Accelerant Dragon Emperor." Stated the voice, with what could only be described as a thick Irish accent.

Ajuka nodded "That's the Horcrux found and destroyed, my Queen will be by in two days with a ritual to find and destroy the other Horcruxes." With that Ajuka vanished as quickly as he had arrived. Dumbledore stood in the shadows of the Gaunt Shack, holding the ring that as he looked at it resembled the resurrection stone from the Fairy Tale 'The Deathly Hallows'.

"Harry, what are you hiding from me?"

Ajuka was good to his word and two days later, Dumbledore had a ritual to deal with the Horcruxes. It as Dumbledore painstakingly read the instructions better than he had ever hoped for; not only did it identify, find and destroy Horcruxes. It appeared to have a summoning component.

Dumbledore looked at it, he knew that this was going to take a lot of his remaining lifeforce or even potentially kill him. With the assistance of Fawkes he appeared back in Grimmauld Place. Dumbledore, for once divulged everything bar the knowledge of Devils. As he finished, he was about to say he was about to do it when several voices spoke, including Harry and Sirius.

There was smoke, fire, sweat and tears with a finale of explosions the horcruxes had been summoned and destroyed. As for Dumbledore, he was okay slightly shaken and looking slightly tired but then again as were Harry and Sirius. Although the raven-haired teen had a rustic looking gauntlet on 'Dragon Emperor', Dumbledore thought as he retrieved the Ring. "Harry, something tells me that you're going to need this in the future." Dumbledore didn't know how true that was.

The rest of the Summer flew by too quickly. Soon enough Harry and crew were heading back to Hogwarts. It turned out to be a grind, Fudge being a Fudge had managed to put one of his lackeys into the Defence Against the Dark Arts position.

(Time jump, OWLS)

Fifth year had been a bitch. Another shitty DADA Teacher with an axe to grind. Harry and Hermione, were definitely regretting the acceptance letters to enter Hogwarts. This time the Toad that had been there DADA Professor was in the firm belief that spells could be done on the first time. It wasn't until the bitch had tried to kill Professor McGonagall did chaos break loose.

It was quite literally wars in the halls. Slytherins chucked spells at whomever, but were quite unprepared for the vicious returns of spell fire. On more than one occasion, Professor Snape had been found stunned in the Hallways as Harry and whichever Slytherin was causing trouble had their throwdown. Harry, quickly demonstrated that he was tired of being pushed around with no help from the Professors and had on more than occasion sent his target and two of his minions to the Hospital Wing.

Funnily enough the Teacher that stepped up to the plate was Flitwick. He had on several occasions walked into several of these corridor duels and handed out disarming, binding and stunning charms like they were lemon drops. Thankfully, this only lasted a fortnight as McGonagall strode in and laid down the law and punished the entire school as a collective. Umbridge had been found in dire conditions in the Forbidden Forest and was now having intensive psychiatric help.

Things came to a messy conclusion when Harry had a spine chilling sensation that Sirius was trapped at the Ministry of Magic.

(Time Jump to the Ministry Fight)

That had been a ruse, and now Harry, Hermione, Ron, Neville, Ginny and Luna had been in a fight for their lives when the Order of the Phoenix descended into the Department of Mysteries.

Harry managed to deflect Sirius away from the Veil and in the midst of the confusion sent a barrage of a bone breakers in a tight grouping towards Bellatrix. She dodged one, shielded another but the third, forth and fifth connected. Two into the ribcage and the last one connected solidly with her skull. There was a momentary pause as everyone saw Bellatrix Lestrange fall, skull cracked open.

Moody grinned and with two redactors and three slicing hexes dispatched the last two males of the Lestrange House. That was one set of dogs dealt with; Moody grinned. He had been desiring to take chunks out of those three for ages, they had killed three of his friends from his time as an Auror… well that was Rabastan for one. Rudolphus, he wanted for the near sexual assault and aggravated assault against his great-great-niece Alice Longbottom nee Moody and didn't forget his own Godson Franklin 'Frank' Longbottom.

Across the Chamber, Neville and Ron with assistance from Lupin and Tonks and successfully taken out Nott, Avery the Second and Ron had managed to somehow with some definite dodgy transfiguration created a beaters special; a beaters bat with a nail in it, instead of a nail it contained glass from the Brain department where Mulciber was hit with one by Luna and Neville had banished a table at him.

However, things were not without consequences. Harry snarled and charged after Antonin Dolohov, a notorious Death Eater known predominately as a Slicer, an archaic term for sorcerers and sorceresses with a intense and intimate skill with cutting spells. Unfortunately, Slicers tended to run in families and none were as profound as the House of Dolohov. Not British Nobility originally but this branch of House Dolohov had moved to Britain shortly after the Black Plague had hit. Jack the Ripper was alleged to have been a bastard squib of House Dolohov. Arthur Weasley, who had previously been bitten by Nagini a few months ago but had been saved by Harry who had received a vision from Ddraig managed to in the nick of time save him.

Arthur, exited the fire place in the Atrium to see Dolohov making a run for the fireplace. Only for the thirty-five fireplaces to erupt in emerald green flames as Aurors, Hitwizards, Death Eaters and various others appearing out of them. However, a convulsion of shadows, mist and smoke appeared in a small circle of ethereal light as Voldemort appeared in the centre of the Atrium, and accompanied by what appeared to be a half-transformed werewolf. That half-transformed werewolf was Fenrir Greyback.

Arthur sighed, he looked around as the battle sparked again around him. He spied the He-Who-Must-Not-Be-Named killing with indiscriminate ease and Greyback making a mess of people. He casually transfigured a recruit into a matchbox as he headed towards the Dark Lord. His memories of his training as a Hitwizard and then an Unspeakable coming to the fore "Let's make this count." He murmured, his magic pulsed, his wand sparked and a torrent of spells surged forth.

Death Eaters and Death Eater sympathizers fell on all sides. Some bound, upside down, others wrapped up in the floor of the Atrium and some dead. Dolohov moved to escape effortlessly cutting down three night-staff as if it was like breathing; considering the Norwegian pureblood had cracked a grin it probably was. Arthur however, smirked coldly "Terrae ad devorandum." (Devouring Earth or rather Earth Devouring) Everyone stopped as the spell rocked the Atrium.

Voldemort turned, his red lamplight eyes in his gaunt nose less face widened. He visibly hurled himself to one side with speed and grace that a man in his late sixties should not have had. He watched as the earth part, form two major walls and then slammed together as if the earth had made a mouth and devoured Dolohov and a batch of his new recruits. Furthermore, he was surprised as a set of extremely dangerous bone breakers came his way. "Arthur Weassssley…it seems you possssesss a backbone like your parentsss…It issss foolish for you to duel me."

"I know. But at least I can die knowing I've done my bit, furthermore I can die knowing I killed the motherfucker that killed my in-laws. At least I can show my…Argentum palmis caedebat." (Silver Hand Slap) Voldemort watched with savage glee as Fenrir Greyback had tried to sneak up on the Weasley Patriarch only to be slapped backwards by a silver hand. "I'm going to leave you with a few scars Voldemort. I'm scared of what you can do, but not you. You…you're just one person."

The duel was fast, electrifying but ultimately as Arthur had foreseen ended in Voldemort's favour. Voldemort looked at his opponent and at his forearm, several cuts had managed to pierce his skin. Voldemort casually waved his hand over them and upon them had the initials of 'AW'. "Arthur Weassley, you fought well and thus Lord Voldemort shall reward you Avada Kedavra…with a quick death."

Arthur Weasley fell to the floor like a marionette "ACCELERATION!" Thundered Harry, having literally barged through a Death Eater in hot persuit of Dolohov. He arrived in time to see Arthur, fall. Said Death Eater, unfortunately ended up with a broken spine and untreated concussion causing him to die when he slammed into the ostentatious and gaudy 'Might is Right' statue.

The ring appeared on his hand, he felt a mantle settle on his shoulder and the wand he won off Dumbledore and his wand of Five Years landed in his hands when the wand transformed. "You, laddeh are teh livin' avatar of teh Tuatha De Danann, don't worreh tis trap been a millennia in teh waiting and teh making. Cannae wait teh see yeh, Son of Peverell; Blood of teh Heavenly Red Dragon Emperor kick some serious ass and take teh names as well. Now kill this sunuva bitch."

Harry grunted and the wand in his left hand transformed into an old iron longsword; wicked, gnarled and carried a razor-edge with old Celtic runes engraved on the side. Voldemort's eyes widened, he had studied Ancient Runes and had perused the books about the Weapons of Britannia and to think his nemesis was wielding possibly the strongest of them all. It was also classed as an equivalent to an artefact known as an 'Upper Longinus'. Voldemort had shuddered, he feared what a Longinus could do. Again he hadn't expected this.

Harry grabbed the sword and his left hand was encased in a dull red draconic gauntlet "Level 1 Acceleration. Level 2 Acceleration: Second Liberation!" There was a rush of energy and Harry's right hand was also clad in an identical gauntlet. "Neither can live whilst the other survives, Tom. For the sake of the shitty future of this shitty world we call home let us end this. ACCELERATE! ACCELERATE!"

Harry moved although it was more of a fade from visibility due to sheer speed. Unfortunately for Harry, Voldemort survived the initial onslaught had it not been for Fenrir Greyback. Greyback's claws sliced deep into Harry's arms just above the gauntlets and his great misshapen mutated werewolf skull with his razor sharp teeth bit cleanly into Harry's collarbone. "Partner, that bite and that scratch are going to put us out of action soon…Unless we initiate the Overcharge."

"Over charge?"

"I manifest at the cost of your lifeforce."

"Got nothing else let's go."

"I, Who shall awaken am the Heavenly Dragon who has stolen the principles of Domination from God. I laugh at the "Limit" and "Infinite" and I grieve at the Dream. I SHALL BECOME THE RUSTIC DRAGON OF ACCELERATION AND I SHALL RACE YOU TO THE DEPTHS OF RUSTIC PURGATORY!" The two voices said. "OVERCHARGE! BOOST!" Harry shouted, however it didn't seem much like him to the rapidly gathering crowd of scared but transfixed Wizards.

Harry's body rapidly increased in size, stretching the skin to the point he looked like an extremely muscled scarecrow. The gauntlets let of the stench of smoke and steam and fused themselves to the forearms and took on the appearance of a dracowolf; a long extinct creature that inhabited what it is now Australia and a few parts of Wales. The Australian one tended to resemble a lean Clydesdale war horse and the Welsh one resembled something close to the size of a Shire. Harry's arms resembled the Welsh Dracowolf with his feet taking on the shape of the Australian. His body sprouted with hair and his face became the face of a werewolf. However all of it was soon encased in armour. "OVERCHARGE BREAKER OF BALANCE! OVERCHARGE DRIVE SCALE MAIL!"

"OVERCHARGE DRIVE SCALE MAIL PROMOTION: BISHOP! OVERCHARGE THUNDEROUS DISCHARGE!" The multitude of voices reverberated around the atrium before the monstrous being Harry had become exploded in an orb of orange light, as it receded a black petrified form of Greyback, fangs still embedded in Harry's collarbone was all that remained. There was a gust of wind and Greyback disintegrated into dust. Harry turned to face a rapidly backing away Voldemort.

"I DO NOT ANSSWER TO YOU, POTTER!"

"No, but you answer to this. Overcharge breaker of balance Ire's Accelerating Dragon! FRAGARACH!" The sword vanished and reappeared emerging from the Gauntlet.

Voldemort began to unleash a torrent of curses and hexes, which never met their target as Dumbledore strode into the Atrium and began to engage the Dark Lord in a breath-taking duel of complex magic and arcs of destruction, animation, conjuration, curses, counter-curse at such a speed it began to heat up the marble.

"You are the Lord Comhnoir Potter! You are a Guardian. You are a Guardian of many weapons and artefacts known as 'Ancient Gears/Forgotten Gears and Anti-Gears' use them!" Ddraig rumbled in his ear.

"Acceleration Dragon Emperor of Ire; twin sword balance break: Left Hand Fragarach! Right Hand Moralltach!" Harry roared, he vanished from view and brought his left arm sword which now resembled a guillotine blade crashing down towards Tom sundering the magical shields he had created. With his right hand also forming into a blade, a double-edged broadsword, slammed into the Dark Lords chest as the guillotine Fragarach sundered his wand arm.

Harry emerged from his armour looking fully human as Voldemort began to leak black ooze, crumble back into his original parts and turn to dust "Ashes to Ashes, Dust to Dust. Fitting."

"Harry, my boy, thank you…Thank you for ridding us…" Began Fudge, only to be looking down the end of a broadsword.

"You were going to congratulate me and then throw me to the curb and try and rob me of my inheritance as I received bites from a werewolf? Surprised? Don't be, I've been studying. I know how this backwater ogliarchal patriarchal corrupt society of inbred fucktards works. Here's what is going to happen, myself and my innocent and free Godfather whom you are going to pardon right here and now along with whoever wants to join us are going to leave here; deal with our business and leave you alone." Harry growled as Moralltach morphed into a staff.

"What I want is simple…I want you to change…and this is how you're going to do it." Harry stated, as he panted with exhaustion and he stared down the rapidly paling and useless lump of flesh in a tweed suit and lime green bowler hat.
