The Revenge of House Black

By: Mymumisgay

A/N: Okay so this story is a going to be massively AU. Basically, in this story Harry Potter doesn't have that much importance, he is more of a supporting character and switches place with Neville Longbottom who is the BWL. The main protagonist is an OC. No ships until later in the story. Please review, I am open to constructive criticism.

Prologue

Late Winter somewhere west off the coast of England 1979.

Drip drip drip patter patter splash BOOM!

The manor shook from the powerful thunderstorm that was taking place outside. It had been like this for weeks now. Regulus Black was staring out the window of his master bedroom, though he could not see more than a few feet because of how fierce the storm was. Regulus Black was a very handsome man. He was of average height but lithely built. He had long and silky black hair tied back traditionally into a ponytail. His face was very striking with high cheekbones, a straight but short nose and stormy gray eyes that was an archetype of the Black Family.

As Regulus stared out of the manor into the storm he contemplated all that had gone on since his graduation from Hogwarts previously that year.

Regulus Arcturus Black was proud to say he had graduated top of his year with 5 N.E.W.T.s and mastery in battle magiks. Regulus was undefeated in the dueling club, the only one who had come even remotely close to beating him was his cousin Bellatrix. That could be excused as she was a Black by birth and Blacks were powerful just by birthright, he thought to himself with some amusement.

What Regulus was not proud of was that straight out of Hogwarts he had bent the knee and taken the dark mark. Now, Regulus actually fully agreed with everything the Dark Lord supposedly espoused. Regulus had no problem and fully supported waging war on the filthy muggles. If he had been alive at the time, Regulus was sure he would have been a major supporter of the Dark Lord Grindelwald. Dark Lord Grindelwald had come from a pure and ancient line of gray to dark wizards, that was well known. But Regulus' masters' heritage was unknown and Regulus didn't like that. Any self-respecting pure-blood dark lord would have proudly broadcast their name. Voldemort was not a pure-blood name and that only made him suspicious.

Boom! A flash of lightning that couldn't have been further than fifty yards away shook him from his reverie.

Regulus turned back and looked to his beautiful wife who lay nude in their massive king-sized bed. Lysandra Black née Selwyn was truly a breathtaking woman but more importantly, she was the love of his life. Lysandra had luscious golden blond hair and a full voluptuous figure that made many a man's head turn. Her face was radiant even when she slept with perfect pink lips that seemed to perpetually smile and the most alluring violet eyes that he was sure could see straight into his soul. Nobody – not even his master – knew she was his wife, nobody even knew that they had eloped in secret because of the war. Most importantly, nobody knew she was nine months pregnant with his child.

Another flash of lightning drew his attention back to the window. Wizard-folk were a suspicious lot and with children and pregnancies over the millennia there had developed countless superstitions. The weather immediately prior to child's birth was said to be a sign of the child's future. A sunny and bright day, for example, was said to be a child who maintained peace and brought prosperity to the house. More direly a child born on a cold night was said to be cursed to die young. Regulus himself had been born close to midnight in the middle of a snowstorm so he wasn't sure how much he believed the old superstitions. Even so, a child born in a thunderstorm was said to be a child of power who brought either brought great happiness to a house or great destruction and with the way the weather had been lately he was very nervous about House Black's future.

Regulus absentmindedly looked down to rub his forearm. The dark mark glowed menacingly in the low light of the master bedroom and again thought of his master. He had joined the Death Eaters when he was still in Hogwarts as his fellow Slytherin classmates had all but blackmailed him to do so. Looking back he knew it was a mistake, a mistake that could cost him the lives of not only himself but his wife and unborn child as well.

The Dark Lord always spoke of pure-blood ideals but that never stopped him from brutally murdering Charlus Potter and his wife. Sure they were light wizards and mudblood loving fools, but still, they were pure-blood and to just murder them like it was nothing made Regulus very uncomfortable. If the Dark Lord didn't hesitate to murder light pure-bloods just because they opposed him on the Wizengamot than dark pure-bloods were surely open-season as well if they dared defy him.

Regulus had to do something to protect House Black's future. He would not just stand aside and let more pure-blood be spilled for nothing, especially when he had an unborn child to bear in mind.

"Kreacher" The house-elf popped into existence before him and bowed so low his long nose touched the floor. "Yes Master Regulus?" Regulus paused and eyed the elf in distaste. He had never liked the insane elf, but he kept that to himself as the disgusting vermin was useful. "Kreacher, listen to me very carefully. I am going on a very dangerous mission and I am not sure if I will be coming back alive." The nasty thing looked like it was about to burst into tears at the very thought of such a thing so he silenced it with a gesture. "Silence Kreacher I haven't much time. I am leaving you with three very important tasks which will be of utmost secrecy and you will tell nobody what I am doing or where I am going with the exception of Lysandra should she ask." Kreacher nodded vigorously and seemed to hang on to his every word.

"One, you are to protect Lysandra with your life if necessary and shut down the mansion with the wards set to kill as soon as I leave. Two, if I do return you are to have a full medikit with blood replenishing potions for me available the second I cross the wards. Finally, your most important task. Kreacher when I return I will have a very dangerous and dark artifact with me. Hopefully, I will be able to destroy it myself but if I am unable then it will fall to you to destroy it by any means necessary. Do you understand?" Kreacher again nodded vigorously and saluted Regulus. "Dismissed. I will be leaving in fifteen minutes. Do House Black proud or I'll have your head mounted on the wall before you can say Quidditch." Kreacher nodded again and popped away.

Regulus spent the next seven minutes writing out a final will and testament before sending it off with an owl to his personal vault at Gringotts. Finally, he went and regretfully woke up Lysandra.

"Lysandra love, please wake up it's very important." Lysandra moaned slightly before she sat up letting the blanket slide off her nude form exposing herself. She opened her beautiful violet eyes and asked in a musical voice "What is it Reg dear? It's two thirty in the morning?" Regulus had to take a couple moments to center himself. Even after a year and a half of seeing her like this she still took away his breath and made it hard for him to think. Lysandra smirked coyly at this and said "Reg love, I hope you didn't wake me because you were frisky. You know with the baby I need more sleep" Regulus blushed scarlet at this. "No love it's not that, but I've decided I need to go on the mission we discussed last week" Lysandra's whole demeanor changed in an instant. She suddenly looked very worried. "But Reg dear, I thought you said it would only be as a last resort" Regulus suddenly looked down and sighed heavily. Lysandra put her finger under his chin and forced him to look in her eyes. "You know you can tell me anything love, whatever is troubling you please tell me."

Regulus had a notoriously good poker face and was known for being one of very few Death Eaters who had good enough skills with mental magiks to lie to the Dark Lord's face. But, anytime he looked into Lysandra's violet eyes he could never say anything but the absolute truth coming straight from his heart. It was one of many reasons he had fallen in love with her.

Finally, deciding he would probably not get another chance Regulus said "I received word two hours ago that Charlus Potter and his wife Dorea my first cousin, were personally murdered by the Dark Lord. They went down like proper pure-bloods though. If the rumors are true they took down close to half a legion of Death Eaters before the whole of Potter mansion was burned to the ground with fiendfyre. They were burned alive."

Lysandra looked shocked and horrified "But Reg dear, they're pure-bloods! Why would he kill them? It makes no sense." Regulus nodded solemnly "I know love, but I think the Dark Lord has finally gone insane. It would seem that nobody is safe anymore. I have to do something. Even if is it a long shot, it's better than waiting for him to attack us too for some minuscule slight." Lysandra seemed conflicted and opened and closed her mouth several times to say something before settling on "I understand love. You have my permission to go even though it's terribly risky and I would rather you don't go. One condition though." She looked at him sternly and Regulus nodded meekly like a chastised puppy. "Anything love" She smiled triumphantly at this. She took his hand and placed it on her very inflated pregnant belly. "You come back to me, you hear me? Our child still hasn't a name and I'll be damned if our child doesn't get to meet their father at least once." Regulus smiled happily at this and gave her a toe-curling kiss. "I swear it, love. I'll be back in no time."

Regulus tucked in his wife one more time kissed her on the forehead and quietly left the bedroom. Little did he know he would be there only one more time.
