The Death-Eater Headquarters, 1st February, 1981
The Dark Lord Voldemort, or Thomas Gaunt according to a magically enforced deed poll filed in M.A.C.U.S.A, or Tom Marvolo Riddle to those who have got a death wish, was a busy man. The war had settled into an uneasy stalemate between his Knights of Walpurgis (or Death Eaters) and the Order of the Phoenix led by his erstwhile Transfiguration professor, Albus Dumbledore. He was now vying for dominance for Wizarding Britain after having gotten a donation of five hundred million francs from wizarding Switzerland who recognized Lord Voldemort as the rightful ruler of Wizarding Britain and the endorsement of the Durmstrang Institute of Magical Learning. It was good, though he did not yet assert his sovereignty over Wizarding Britain, thanks to the Order.
Though he knew that he was immortal, nevertheless he couldn't help but feel that he was rather short on time. Especially, given the prophecy about some vanquished of his who would be born at the end of July. Well, the Dark Lord wasn't exactly known for his patience and he decided to dive into his personal library with books bought, procured, gifted or stolen from all parts of the world. He decided that he could devote more time to studying magic and conquering the world by getting rid of his biological need of sleep permanently.
He picked up a volume of Secrets of the Darkest Art, the very same book from where he had learnt about horcruxes and looked for a solution for his conundrum. "Lord Voldemort owes you gratitude, Owle Bullock", Voldemort hissed to himself while poring over the mediaeval tome and he found Ekrizdis' potion for eternal sleeplessness that amongst other things, required one to have their issue kissed by a Dementor and the kissed body being cooked in a concoction of unicorn blood and obscurial flesh which is then consumed by the person who intended to be free of the need to sleep while at the same time conferring any magical powers that the victim of the ritual possessed to the recipient.
He was glad that he preserved some of his own semen before splitting his soul for the first time in '43 as horcrux creation is known to cause sterility. Unicorn blood can be easily obtained and he has been farming young Mudbloods, berating them for using magic in order to create obscurials.
It was time to find a suitable host for his issue to grow in. After all, potions required utmost caution and purity of ingredients as Horace Slughorn was wont to say and only the most capable of witches would be worthy of carrying his spawn.
Having kept that in mind, he summoned Bellatrix Lestrange, widow of Rudolphus Lestrange. She was a Black and a witch of the purest blood, she was quite magically powerful and the Black bloodline carried the power of being a metamorphmagus. Phineas Nigellus Black was reputedly one of them.
"How may I serve you, My Lord?" , Bellatrix asked her Lord.
" Bella, there is a ritual that requires one to cannibalized one's own child that would confer upon the drinker, any magical powers that the victim would have manifested, had he been allowed to live and furthermore, the recipient of the potion achieves a state of eternal wakefulness, in short freedom from sleep ", Voldemort addressed her.
Bellatrix simpered, looking pleased with herself. She was finally going to bed the Dark Lord and her face turned deep red, a shade that Molly Prewett would be proud of.
"My Lord, I am most willing to carry our child...and to do anything to accomplish it", Bellatrix drawled seductively.
The Dark Lord retreated into his private chamber and injected his preserved forty year old semen in his withered privates and he called for Bellatrix. After an hour of passionate lovemaking, Bellatrix had finally conceived and Lord Voldemort had finally lost his virginity.
Lord Voldemort then described the ritual to Bellatrix and decided to reward her by sharing some of the potion with her. Bellatrix thanked her Lord profusely for being honoured in such a physical manner and Lord Voldemort ultimately dismissed her, deciding to have some bangers and mash while his beloved Nagini feasted on a doe.
No. 12 Grimmauld Place, 1st November ,1981
Bellatrix was in labour. Aye, this was the day when she would ultimately deliver her daughter whose sacrifice would make her Lord more efficient and she was glad that her Lord decided to share the potion with her. Though, it was marred by the fact that the Dark Mark has faded and the Daily Prophet had reported the 'death' of the Dark Lord at the hands of a one and a half year old infant.
"Preposterous ", Bellatrix huffed to herself. Her Lord was immortal and she knew it, for her mark was still there, the fading notwithstanding. Her Lord was disembodied, not dead. And it was all due to the wretched brat she was carrying.
She convulsed for a while, shrieking in agony and after a painful hour that rivalled receiving the occasional Crucio from her Lord, she had finally given birth.
Meanwhile, Walburga Black was sipping butterbeer in the dining room, mourning the Dark Lord's demise when she heard Bellatrix screaming.
"Bella, control yourself!" , she yelled at her niece and when Bellatrix continued shrieking in pain, Walburga decided to go to her room. She saw her niece holding an newborn with greenish silver hair, definitely a metamorphmagus.
Bellatrix cooed to her daughter, " Soon my little pet, the Dark Lord will return and you will serve him more faithfully than the rest, for the Dark Lord needs a potion that requires one to sacrifice their child. See, little brat. I am the Dark Lord's most faithful and I am the only witch who has bedded him. It was the happiest day of my life and yet you have put me in a lot of pain " Bellatrix then put her daughter on the bed, pointed her wand and yelled, "CRU-..."
"STUPEFY!", Walburga screamed, and Bellatrix dodged the stunner.
Bellatrix said, " Auntie 'Burga, did you know that I have been chosen by the Dark Lord to carry his heir. It is such an honour..."
Walburga replied, " I have heard your monologue and no, YOU WILL NOT KILL YOUR DAUGHTER!"
Bella simpered and replied, " Auntie 'Burga. She won't be killed now. We need to keep her alive till the Dark Lord returns..."
Walburga shot a bone-breaking curse at her which struck her left hand.
"HOW COULD YOU DO THIS TO YOUR OWN FLESH AND BLOOD FOR A DEAD MADMAN, BELLA?" , Walburga shrieked.
" DON'T YOU DARE INSULT THE DARK LORD!" , Bellatrix shouted at her aunt and shot a killing curse towards her.
Walburga conjured a boulder which was shattered into smithereens by the incoming killing curse.
" Or have you become a muggle-lover like the mutt that you have given birth to " , Bellatrix taunted.
It was a low blow. Walburga's face went white as snow, her grip on her wand tightened and she yelled, "SECTUMSEMPRA!"
A deep gash appeared on Bellatrix's shoulder, her blood being sprayed throughout the room. Bellatrix disapparated. "Prince's son is a genius " , she muttered to herself. She knew Severus, thanks to her younger son Regulus and Severus had a very sharp mind dedicated to the study of the Dark Arts and Potions.
Walburga Black picked up the infant and went to her husband, Orion.
"Look, Ori. Bella has rutted with Riddle to bear a daughter that was intended to be sacrificed for some ritual. Just how could she? SHE IS A BLACK AND FOR BLACKS, FAMILY COMES FIRST!" , Walburga yelled. She was extremely disappointed with Bellatrix and she picked up her wand, and stormed towards the tapestry.
There she saw that Bellatrix Lestrange had a daughter with someone named Thomas Gaunt. "Well, Riddle grew up in an orphanage ", she thought aloud and she took her wand, poked Bellatrix's picture in the tapestry and with a swish and stab, she burnt Bellatrix off the tapestry.
"Can you explain everything to me?" , Orion asked his wife.
"I'll show you, Ori ", Walburga told him and called for Kreacher.
"Kreacher, take us to the pensive room! ", she commanded.
Kreacher nodded and took Orion and Walburga to the aforesaid room and Walburga showed her memories of her encounter with Bellatrix to Orion who dived into the pensive. A few minutes later, Orion emerged from the pensive, looking very shaken.
"Sweet Salazar, she tried to kill you, 'Burga. How could someone do this to their own flesh and blood, their own child?" , Orion whispered in a deceptively calm manner. Bellatrix had tried to off his wife and tried to raise her daughter as a mandrake to be chopped up for potions. She does not deserve to be a Black.
"Kreacher. Get my father, Cygnus, Uncle Pollux, Aunt Cassiopeia and Druella immediately. It's Black family business " , Orion ordered the elf.
"Kreacher lives to serve the most Ancient and Noble House of Black ", Kreacher muttered and disapparated.
"So what are we going to do about Riddle? ", Walburga asked.
"So, why did you summon a Black family meeting? ", Arcturus asked. He decided to hand over the headship of the Black family to his elder son Orion in 1980 on account of advanced age.
"To discuss the circumstances leading to disownment of Bellatrix Elladora Black from the Most Ancient and Noble House of Black ", Walburga answered. " You can view the memories in the pensive."
One by one, they all viewed the memories. Arcturus and Cassopoeia looked indifferent whereas Cygnus and Druella, and Pollux all looked extremely furious.
" You did the right thing Walburga. Bellatrix had gone insane. Blacks should never attack Blacks ", Pollux consoled his daughter.
" Bella was just following the Dark Lord's orders! ", Cygnus whined.
" Little Swan. I saw her use the Cruciatus on your newborn granddaughter ", Walburga chided her brother.
" But still, you shouldn't have disowned her. She's a very capable witch ", Druella argued in favour of her daughter.
" She shot a killing curse at Walburga Alexia Black, with malice aforethought (for that sentiment is necessary to cast the spell) at a member of the House of Black. She should be disowned" , Arcturus added.
" I agree with Artie. But wouldn't disowning her would attract the Dark Lord's wrath? ", Cassopoeia wondered aloud.
" Haven't you heard, Aunt Cassie? The Dark Lord died while attempting to murder the Potter boy", Orion told her.
" What about the daughter? The Gaunts are an insane lot. I sat on the trial of Marvolo and Morfin Gaunt about sixty years ago. They were more brutes than men. They spoke only in Parseltongue. I say, let's dispose of her", Arcturus asked the gathered assembly.
"But she is the Dark Lord's daughter and my granddaughter", Cygnus yelled.
" I agree with Artie. I attended Morfin's trial for murdering a bunch of Muggles in the '40s and the Gaunts are a disgrace to British wizardry. I'd rather be a Weasley instead of a Gaunt", Cassopoeia added.
" That's my great-granddaughter you're talking about ", Pollux snarled and pointed his wand towards Cassopoeia.
" We haven't named my granddaughter yet. I am proud to be a grandfather of a metamorphmagus " , Cygnus declared, pride evident in his voice. It was true. The memory showed that she was indeed a metamorphmagus and he was on cloud nine. He was unaware that he had another metamorphmagus granddaughter, one born to Amdromeda and Theodore Tonks and even if he knew, he did not care.
" She'll be Delphini, after ze constellation of Delphinus and the giant serpent killed by Apollo. I think that we should name her Delphini Walburga Gaunt. After all, she was saved by you ", Druella declared.
" Thanks, Dru" , Walburga muttered wiping a tear from her eye with a handkerchief.
So, the House of Black had gotten a new member and Cygnus went to the owlery to write a letter to Narciasa about Delphini. After all, her little Dragon had gained a new cousin. All was well.
Except that the very next day, Sirius Black was sent to Azkaban for life sans trial followed by Bella, Rabastan Lestrange and Barty Crouch Jr. ( who were tried properly).
