I don't own Harry Potter.
The three Black Sisters cut their palms and formed a circle of blood they got to the three point healed their cuts pulled their auras all various shades of black and started the chant as the hearing started.
"Are you Harry James Potter of 4 Privet Drive Little Whinging, Surrey, England correct" said a squat witch that had pink scarf draped over her robes looking at him. Harry surveyed the panel and saw the base members of the Wizengamot and the minister and two wizards missing then turned and saw all the Court House Lords that have rank. "Today Mister Potter"
Harry turned back to the main panel and rose to his full height and he knew the correct phrase that will make him The Duke Potter. "I am Lord Hadrian James Black-Potter Head of the Most Ancient and Most Noble House of Potter formerly resident of 4 Privet Drive, Little Whinging, Surrey, England." A rousing red aura burst from Harry showing all who he was and then the center seat of the Seven box glowed red in connection. The Panel was furious in the thought that they were going after a Duke and Head of the Seven.
"That is a lie Mister Potter no half blood can be a Lord of one of the Seven it is in the by-laws and you are too late to even claim such a title is it right Scribe Weasley" said Fudge outraged the Potter was trying to usurp his power play to end him and Dumbledore in one way or another. Percy was about to respond when a witch with a monocle and a square jaw replied "Minister Fudge that is not true and if it were the seat would not recognize him as the holder"
"Now see hear Amelia you know for a fact this boy cannot be the Head Potter Dumbledore said so himself that the Potter only wanted pureblood Lords"
"Umm Minister how would Disgraced Viscount Albus Dumbledore know anything about the Potter by-laws unless he was a Potter by blood" said Harry looking at Fudge seeing Madam Bones nodded in agreement recognizing her from Aunt Bella's description of her. "Seeing as I'm a Pureblood Heir of one of the Seven the Underage Restriction does not apply to me and the magic was used in front of a muggle who knows about magic." The Panel was discussing this when a cry came from one of the Lords and Percy then said "Viscount Malfoy you can talk"
"Potter you are not a pureblood let alone an heir we know your Mother Lily Anne Potter nee Evans was a muggleborn so stop with these lies" and all of his allies nodded in agreement.
"Oh I make sure your wife knows you are calling her cousin the Princess of the Black Line a muggleborn may I cast a spell Lord Ogden"
All eyes turned to Tiberius Ogden who nodded to the boy in the defense chair as he nodded Harry's cousins were laughing at how he had stalemated the whole Wizengamot in one move.
"Ostendere hereditatem" a white flash shown as nine names appeared in the air above Harry "You see I'm the son of Duke James and Duchess Ophelia Potter grandson of the previous Potter Duke and Duke Orion Black. So I'm a Pureblood Viscount Malfoy." The whole room was silent when it came out that Potters and Blacks were married "And oh Mister Minister that means Duke Black as in Sirius Orion Black III is not responsible for betraying my parents as Black and Potter law states that family cannot turn on family." Everyone was stunned except for the cousins who knew this as fact. The squat woman was furious she stood up and screeched "Mister Potter enough of these lies you know you are guilty of cast magic in front of a muggle and should be banished from the wizarding world" Harry saw that most of the Panel was mad at this woman for her gall in yelling at The Duke who controlled their fate as Head of the Seven.
"Ah now I know who you are squat, toad looking (causing many to laugh) wearing gaudy colors and a poor temper you must be Former Disgraced Baronetess Delores Jane No Name-Umbridge how nice it is to meet you" this caused the woman to become very upset at how he talked to her and the Wizengamot was silenced as Family Secrets were pulled out of the air.
"I'm the Baronetess Delores Jane Selwyn-Umbridge you little pond scum you do not belong in this world" she said with a glint of maliciousness. When Harry shook his head and then turned to the Scribe. "Scribe is Marquess Selwyn present" Percy paled knowing where this was going and turned to look at Fudge who paled as well. "Yes Your Grace he is" a man with long blond hair in sterling blue robes stood up and said "You have need of me cousin" shocking everyone to see that the Marquess Selwyn was Potter's cousin the Death Eater block was furious because he had disowned his siblings for support their Lord.
"Is this woman to put it politely your relative?"Harry asked speculatively.
"No the bloated toad of an Undersecretary is my disowned and disinherited younger sister"
"Thank you My Lord Selwyn" he had a smirk as he said this and turned back to the panel and said "Can we have the verdict before the old goat comes." He silent had a tie to his Aunts telling him that the ritual was ready and that the spell would come into effect when the Court Doors open and since most of the heirs are here as well two birds with one stone. Finally Fudge gave up and said "Fine what say you The Lords of the Ancient and Noble Houses" Three for and Two Abstained "What say you The Lords of the Ancient Houses say" Four for, Two Abstained, Two Against. "What say you Lords of the Greater Houses" Eight for, Four Against and One Abstained. "What say you Lords of the Lesser Houses" Five For and Three Against. "And what say you My Lords and Ladies" Four for. Percy Weasley stood up and said in a clear and loud voice "His Grace The Duke of Potter is hereby now cleared of all charges of underage magic" Just then the doors flew open and Albus Dumbledore strode in with aura full tilt make some happy and some furious. "Fudge stop this farce of a trial I have proof that Harry Potter is clear of these charges" all laughed at Dumbledore when a pretty girl with raven black hair and stunning purple eyes stood and said "Headmaster the trials is already over and His Grace is already cleared you are too late". Dumbledore paused when heard the Young Greengrass he was happy to hear Harry was cleared but paled when she said His Grace meaning he had ascended to his place in the court. Meanwhile Harry saw his Aunts stride in and in one voice said " Members of the Royal Court of England we Sisters Black have one more thing to bring to your attention" all stopped and stared at the three women varying in looks from black to blond hair and all pale skin. They unleashed their auras which were gray as branch Blacks and said "Tres, sorores antiquissimae nobilitatis domus atra dare sanguinem magicae parum vocare tribus sororibus magna Sic fiat" Dumbledore paled knowing what that spell did he hoped it did not work but a strong black wind blew thru the chambers shutting the doors behind the Sisters. And three beings dressed in pure black that reflected light stood three women that looked like the Black Sisters.
"Who have awaken us The Sisters Three" the Black Sisters stood firm and said " We sisters three have summoned you to find and help train the Heirs of your blood that you find worthy and have not Gated yet"
The middle one stared at them then turned towards Fudge and Dumbledore who paled realizing the seriousness of this summon that was made outlawed and very dark and very heavily punishable with being thrown into the veil. "I Princess Morgan Le Fey say we Three Sisters will grant you your boon we will call our worthy descendants that we sense in this room starting with my Older Sister Elaine's Line" The red headed woman to her right straightened and her clear hazel eyes burning with power "I Call forth Lady Susan Bones, Lady Hannah Abbott and Patricia Abbott" the three girls were in the Sevens Box and vanished Susan in a flare of purple light and the Abbott sisters in a flash of blue. The woman then turned to Dumbledore and said "Your line is a disgraced that should not have been born but that Rapist made sure you survived my wrath you bastards" she vanished in black smoke. All eyes were on Dumbledore to tell what she meant. But had to wait when Morgan spoke again "My Younger sister Morgause will call her line" the woman with brown hair nodded and said "Lord Hadrian Potter, Lord Aurealis Black, Lord Neville Longbottom, Lord Draconis Malfoy, Lord Blaise Zabini, Ladies Callidora Potter, Cassiopeia Potter, Enyo Lestrange and Psyche Rosier" Harry, Blaise and his sisters vanished in red light, Neville in pink and the rest in black light. She stared at Dumbledore with her white eyes and growled " My legitimate heir is grown and making the right decisions for his family but he has already gated so bring Viscount William Arthur Bones-Weasley is the Head of the Most Noble House of Weasley" she vanished into black flames leaving a scorched mark. As Morgan laughed at the stunned audience and said with a giggle "Lady Daphne Greengrass, Astoria Greengrass and Lady Tracey Davis, and oh they be back in timing for the Gating Headmaster" the Greengrasses vanished into green light while Tracey vanished in yellow light. She left with a laugh into black wind as the Black Sisters vanished from the Court room as it descendant into madness.
