A/N: Welcome, one and all, to 'The World Changed!' This is the sequel to 'When Sirius Jumped Dimensions and Traveled Through Time.' Yes, the title was chosen to follow and complete the first title. I thought it was clever. Eh, whatever.

Disclaimer! Anything you recognize from books/movies is not mine and should not be considered mine. Craziness, insanity, randomness, Siriusness, and SpiderRegulus? … Meh, actually, I got that last idea from 'Harry Potter and the Deus ex Machina.' Excellent story. Hands down the best representation of Regulus Black I have ever read. Anyway, without further ado, 'The World Changed.'

Chapter 1: The Black is Back

Regulus was glad he hadn't sold his flat in England. Not only had it been so modified and personalized that it could never be considered Muggle again, but it was in London. Halfway between the Ministry and the Leaky Cauldron. Now that the war was over, he could see wizards and witches filtering back. Also, he figured it was time he left Ireland once and for all. He hated being called Reggie all day. And truck driving was not his preferred career. Besides, he could do a lot for Wizarding Britain in the legal system. So, he quit his delivery job and 'moved' back to England, suddenly reappearing in the magical world in a suit and tie with a briefcase filled with reforms and a scowl that just begged idiots to try and stop him. Some fools did. He simply stood through their tirade, then blinked and asked, "Are you done? Because I have a meeting with the Minister in half an hour on behalf of my House at the behest of Lord Black. I'm sure Minister Bagnold would be delighted to hear that you detained the envoy of House Black over something trivial." While the fool was gobsmacked, Regulus strolled right along. It wasn't long before Regulus Black was the face of the Black family, as well as a major player in the legal department of the Ministry of Magic. The young man, now a bit wiser in the ways of the rest of the world than his compatriots, made changes right from the get go. He started small, a few domestic things over the course of six months, just to make himself a face and a name in the game. Then things started heating up. He engineered someone calling him a Death Eater in the middle of a Wizenmot Session. He simply gave a grin and removed the illusion from his robes, showing that they were altered to bare his left arm from just above the elbow.

"You... what?" a grizzled old witch sputtered, torn as to what to feel about the act. On one hand, she liked his flare, but on the other, he had just defaced the traditional Wizenmot robes! And besides, showing that much skin was simply not done. Regulus smirked.

"I'm making a statement. My arm is bare, I am unmarked by the Dark Hypocrite. This... is my undeniable statement of innocence... and I challenge you all to bare your arms with me. Prove to us all you are no slave to the half-blood son of a near squib and a muggle landower!" there was some muttering at that. Was he implying what they thought he was? "The Wizarding World has lived in fear of these Marked for far too long," Regulus intoned, his voice soft yet filling the silent chamber, setting the air to thrumbing. Those who weren't numb thought to themselves, yes. He is implying what I thought he was implying. "It is time to remove that fear, which means finding the Marked and giving them their just desserts. This will help," he said, raising his bare arm. The old witch who had questioned him sighed, but altered her robes as well. Traditions and modesty were important, but this was more so. Regulus' smirk deepened. "It has begun," he intoned once again, an ominous feeling rippling through the already thrumming air as he spoke. Some thought he had just given them a short prophesy, others thought he had activated some spell. Regulus himself was mildly surprised by the ripple of magic that pulsed out of him. What was that? But, he shook it off and continued about his day.

/*/

Sirius grinned as he came for a meeting with a British supplier. Every where he looked he saw people without left sleeves. Nodding to a passing matron, he altered his robes to show his left arm. The kind smile he received made his grin just a little brighter. "Why are people all showing their arms?" he asked his supplier. The man snorted, shaking his head.

"Odd as it is, it is now law that anyone may challenge another to bare their left arms to prove they are not Death Eaters. Rumor has it your brother's the one who started it. Bared his arm in the middle of a Wizenmot meeting 'e did." Sirius laughed.

"Sounds like Regulus to me! The kid was always a bit flashy. Especially when making a point," he said. The supplier, who looked like Tom the Barkeep's younger brother, laughed as well.

"Sounds a bit like you as well, Mr. Black! Now, how much of this puss was you wanting again?" Sirius nodded, rattling off his list once more. Mind firmly back on business, Sirius passed his time uneventfully... until that evening when he went back to the flat he and his brother had been given by their father all those years ago.

"AAAAHHHHHHHH! Where did it go?! NO! I NEEDED that!" Sirius slowly pushed the door open as the sound of screaming and frantic paper shuffling came from his brother's study.

"Regulus?"

"AH!" The younger Black Brother jumped, spun, and fired off a non-verbal incarsorus at the sound of his brother's voice. Luckily, Sirius was still in top form and dodged the spell. Mostly because he had been half expecting it. "Oh, it's you. Have you seen my paper on bloodlines and their effect on hereditary insanity? I can't seem to find it anywhere!" Regulus said, calming down.

"Regulus... I haven't been here in years. I have no idea where your paper is," Sirius said slowly and calmly. Regulus still looked a little wild. With a deep sigh, as though the answer grieved him deeply, the younger brother shook his head.

"That's okay. I just need to find it by next week." Sirius blinked.

"Next... ? But... you were..."

"Yeah. It's driving me crazy! I know I need it, and I thought I knew where it was, but when I looked just to make sure... it wasn't there! And now I can't stop thinking about it and I can't find it and... and... GAH!" Regulus responded. Sirius shook his head.

"Accio Bloodlines and Insanity, a Paper by Regulus A. Black," he said, swishing his wand. He was immediately buried under a mountain of paper. "AH! REGULUS! WHY DIDN'T YOU WARN ME IT WAS SO BLOODY LONG!" Sirius yelled as he was buried, and cut more times than he cared to admit, by the papers. Regulus laughed and rubbed the back of his head.

"Oh look, there it is," he said weakly. One gray eye glared at him from under a mound of paper.

"I hate you," Sirius grumbled. Regulus laughed sheepishly, then vanished with a soft whoosh of displaced air. "Stupid spell crafter. Now how do I get out?" the elder brother groused, still covered in paper. He was still covered in paper when Regulus came back with two mugs of frosted lemonade. "That doesn't make me forgive you, you stupid spell crafter," he growled. Regulus shook his head.

"That, my dear brother, is a contradiction. Much like a cowardly lion, a guileless snake, and a dishonest badger," he said, sorting the papers with a swish of his wand and helping his brother up before giving him the second frosted drink.

"Doesn't stop me from being mad at you, you crazy person," Sirius said, drinking his lemonade ice cream. Regulus shook his head.

"The L.O.S.S agenda is moving forward. I've even got a few staunch supporters backing me, James Potter among them," he said, jumping conversation topics with an all to practiced tone. Sirius sighed.

"James... I wish we could make up already but until Dumbles is well and truly out of the way, that can't happen."

"I could arrange for the esteemed headmaster to have an... accident," Regulus stated delicately, sipping his own lemonade goodness. Sirius shook his head.

"No. No that won't do. I don't want him dead."

"Who said anything about dead? No, I was thinking more along the lines of a Lockhart," Regulus said. Sirius hummed, then shook his head.

"Too kind. Besides they might find a way to bring his memories back. No. We need to discredit him, take away his power base. Like with the living Death Eaters. How's that going anyway?"

"Not too good. I've been focused on preparing the house, so to speak. I need a 'good boy' image before I make our move. So, the sleeve trend is done, what's next?"

"Oh, just keep doing what you're doing. Reform reform reform," Sirius said. Regulus nodded.

"I should be ready by Halloween next year," he said. Sirius shivered. "Hey! Don't worry! We'll all be there, so They would be foolish to the extreme to attack. Now, drink your lemonade and tell me how the shop is doing," Regulus said, hoping to calm Sirius down. Happily, it worked and the brothers shared a wonderful evening together.

/*/

Albus Dumbledore was not happy. No siree Bob. In fact, he was quietly stewing in the corner as Regulus Black preached reform and equality. Change. And James Potter, a wizard Albus Dumbledore had thought was quite firmly his man, was supporting the Black! Granted the wizard did so with reluctance, but the Potter Head found the changes to be good and needed. Still though, Dumbledore's pawn was working against him! It was a little known fact, but Dumbledore did not like change. Oh he was all for life and second chances, but out and out change? No. Absolutely not. Everything was just fine! Why fix what wasn't broken? Sadly, there was a fundamental flaw in this reasoning, especially when applied to the current Wizarding government in Britain. It was broken. It was corrupt. It was a a gambling den full of lies and sin that was dressed up to look like something respectable. And Regulus had started by cleaning the walls hidden under the glamour. Now, he was repairing and painting the walls. Soon enough he'd be stripping away the glamour, putting in wiring, firing the staff, and turning it back into the court of justice and order it was meant to be. Dumbledore, however, could not see this as a good thing. He couldn't see it at all. He fancied himself the chess master and now, someone was playing with his pieces. The board was changed. And his pawn was helping! "And so I'd like to bring up the funding for Hogwarts School. Headmaster Dumbledore, do you have a budget for the school?" Dumbledore blinked. Budget? Funding?

"Dear boy, Hogwarts is outside the Ministry and..."

"Well then, dear man, we had better look at the charter and see if that is true. Tuffy! Could you bring the Hogwarts charter please? There seems to be a misconception going around!" Regulus countered. Dumbledore was about to say that Hogwarts elves only responded to the Headmaster when the elf known as Tuffy appeared with the Hogwarts charter and handed it to the Black with a happy smile. "Thank you Tuffy," Regulus said with a return smile. Tuffy bowed low and said,

"Anything for Master Reggie Sir!" before popping back to Hogwarts. Regulus nodded to the empty space and unrolled the charter. What followed was a long, tedious, and rather painful(for Dumbledore) round of 'oh really? Psyche! You've been living a lie!' along with a bonus round of 'huh, well what do you know, that was illegal!' It ended with a Wizenmot ruling to a.) find out what happened to the Founder's Heirs, b.) conduct an audit of Hogwarts finances, c.) conduct an inventory at Hogwarts, d.) replace any broken or dangerous artifacts with new or less dangerous ones, e.) conduct a though check of the professors and the curriculum of Hogwarts and finally, f.) find a new headmaster. Albus Dumbledore left that session with a lot less influence and a taint on his sterling reputation.

Rupert Dundle was not a pure blood, and as such, he was very glad to have his job. When Regulus Black, the political powerhouse of House Black, had asked him if he could print something for him, Rupert had jumped at the chance. Regulus had asked for a week to get things together and Rupert had eagerly given it to the wizard, siting that he himself would need to set a few things up, such as a foreword. Regulus had grinned, a rather frightening grin at that, nodded his thanks, then left chuckling evilly. That had been a week ago. Now, Rupert was shooting wary glances at his office door, just waiting for that evil specter to come swooping in. He got a nasty shock when that didn't happen. "Afternoon, Mr. Dundle," Regulus Black's cordial voice said. From above. Then the man himself came smoothly into Rupert's line of vision. Upside down. Without his robes falling down around his ears. Or his hair for that matter. "The paper I requested you print, Mr. Dundle," the upside down wizard said, laying a very thick paper on the desk before the gasping muggle-born. "I say, are you alright? You're looking a little peaky, Mr. Dundle."

"You're on the ceiling!" Rupert finally said. This just seemed to amuse the evil man.

"Why yes, I am. Is there a problem with this?" he asked. Rupert somehow managed the courage, or was it stupidity?, to glare at the Black.

"Are you part vampire or something?" he asked. Regulus laughed, flipping off the ceiling, and settled neat as you please in the visitor chair.

"Something, Mr. Dundle. Something. Now, the paper? Are you going to look it over?" he replied, nodding toward the very, very, thick pile of papers on the desk. Rupert regarded it, then sighed.

"I've got my work cut out for me with this. Yes, I'll look over it before I publish it, but not with you here. I wouldn't want to keep you from your other important appointments," he said, tapping the large pile with a single forefinger. Regulus shrugged, stood, gave a cordial nod and said,

"I look forward to your good work, Mr. Dundle," then spun on his heel and vanished in a soft murmur of wind. Rupert was gobsmacked by the exit.

"How did he get rid of the noise caused by apperation?" he asked the now still air of his office. Of course, he got no answer, but it is a question everyone asks. That or they exclaim that they have got to get the Black to teach them the trick.

Two days later, the Daily Prophet printed 'Bloodlines and Insanity, A Paper by Regulus A. Black,' with this foreword by Rupert Dundle.

/*/

Regulus A. Black, an enigmatic political powerhouse acting on the behalf of his aging grandfather, Lord Arcturus Black, is a remarkable man. A bright student, when he vanished from our world directly after he graduated Hogwarts School of Witchcraft and Wizardy many mourned the loss. When he returned, one short year ago, many were befuddled by the moves he made in the Ministry, but welcomed the breath of fresh air he brought with him. Now, he delivers an extensive and thought provoaking paper on bloodlines, genetics, and the quirks that sometimes appear when bloodlines cross themselves. 'Bloodlines and Insanity' has had even myself questioning the wisdom of our elders and ancestors as Regulus Black brings to light Muggle advances in genealogical research. Perhaps our views are wrong. Perhaps, muggles are smarter. Perhaps, it is not the muggleborn who muddy the bloodlines, but purebloods themselves.

/*/

Regulus was quite pleased with the foreword, as well as the response garnered by the contents of his paper. Purebloods were muttering, half-bloods were smirking, and muggle-borns were finding themselves suddenly being considered with curious eyes rather than contemptuous sneers. Sirius was cackling in his Ireland home as he read all the editorial letters that had been sent in. Outrage, shock, and cries for proof covered the whole block. Soon, the Prophet was forced to re-publish muggle medical reports and studies for the magical population. St. Mungos sent some trainees to study at muggle medical school to find out what they could of genealogy and what it could mean for the Wizarding world. All the now inactive Agents of L.O.S.S. couldn't help but cackle in glee as the undeniably backward and caged society was dragged closer to the muggle world and forced to take a wider view. There were those who flat out refused to look, to accept, but L.O.S.S. had anticipated this. They had another plan in the wings that would see the whole of their world seeing the metaphorical light soon enough. For Dumbledore, this meant he had to find a way to get Regulus Black out of the way. The boy had dangerous ideas, and he was spreading them. What was worse, the public was drinking it up and those who resisted were treated as the unlikable grumpy old men and women that nearly every street had and all the children avoided out of fear. Things were not going well for Dumbledore, not well at all.

/*/

Sirius was considering moving back to England. His public relationship with James wasn't where he wanted it and I wouldn't be if he didn't make a public appearance with the Auror. So, he branched out his prosperous joke shop and moved the headquarters to England. Regulus, who had reappeared in England's magical world not long after the defeat of Voldemort and started work with the legal department of the Ministry, was rather happy with this. Not only did it mean he get to his brother without international red tape, it allowed Sirius more access to the rest of the family, something the man needed and deserved after the hard life he's been forced into. Both times. However, coming back to England had unexpected repercussions for Sirius. "Say what?" he asked the Ministry official. The young woman shuffled, a little unnerved by the scarred businessman's stare.

"You are required, as Heir to the Black Family, to undergo an Inheritance Ritual in an attempt to find the Heirs of Hogwarts," she said softly. Sirius frowned.

"Why the Heir of House Black and not the Head?" he asked. The young woman took a deep breath and squared her shoulders.

"Lord Arcturus Black requested that you take Headship of any other Houses the Black family may have unknowing control over," she said. Sirius sighed, raking a hand through his hair.

"If there are too many, could I abdicate some to my younger brother, Regulus?" he asked. The young woman shook her head.

"I'm sorry, Sir. I am only a low level worker in the Inheritance Hall, I don't have the clearance for that information," she said. Sirius sighed, but held out his arm.

"Well, let's not keep the circus waiting," he said, resigned to what was to come. The woman chuckled softly, but took him as requested.

/*/

Regulus took one look at his brother and summoned the fire-whiskey "How many?" he asked, once the older wizard had sat down... and shoot back his fist glass like it was nothing.

"Too many." Regulus rolled his eyes.

"Obviously, or you wouldn't be drinking so fast. How. Many. And which ones." Sirius glared. He was no fool, he knew Regulus wasn't asking. He was demanding. Darn pesky Black with the mind of a Ravenclaw, the cunning of a Slytherin and the blunt courage of a Gryffindor!

"Well... lets start with the minor ones shall we? Seven. Major? Well..." he took a deep breath and Regulus snatched the fire-whiskey away. Sirius glared, but relented and said, "Slytherin." Regulus' eyes bugged out and his mouth dropped open.

"Okay then... you're going to have to have quite a few kids to handle all that. One House for each. That's... nine kids, and one of them will bare the name Slytherin... Wow."

"I want you and your branch to take a few, Regulus. I... I don't want that many. Especially Slytheirn." Regulus glared at his brother and said,

"I abdicate any right to he House of Slytheirn, giving full rights to Sirius Orion Black and his line. SO MOTE IT BE!" Sirius gaped at his brother, then sighed, dropping his head.

"Fine. I, Sirius Orion Black, do lay claim to the Headship of House Slytherin. So mote it be," he said. When he was finished, a heavy silver ring appeared on the table before him. Shaking his head, he picked up the ring. "Why am I not surprised?" he muttered, then lifted it high and said, "I, Sirius Orion Black, to claim my right as Head of House Slytherin. So mote it be!" A sharp prick, a slight tingle, and Sirius knew he was the head of a House of one. "Wonderful. Now, about the minor Houses..." Regulus groaned. It was going to be a long night.

/*/

"Remind me to never agree to be your drinking partner ever again," Regulus moaned the next morning. Sirius chuckled nervously at the glare his brother was giving him... even if said brother looked terrible and was hugging a big plastic bucket. Sirius thought it was the mop bucket, but he wasn't too sure. Regulus seemed to have a thing for buckets. Shaking the thought from his slightly achy head, Sirius handed his brother a vial of hangover reliever.

"Yeah... sorry about that. Never thought our family was next in line after the Guants though. Heh, I actually thought Harry would be a descendent before me! How silly is that?" he asked, looking off into the distance. Regulus shook his, now pain free, head.

"Hey, have you tried seeing if you got any family magics from Slytherin?" he asked. Sirius froze, then gave his brother his patented 'are you an idiot?' look. "Right. Well, here. Serpentscosia!" Regulus said, flicking his wand and conjuring a snake. Sirius glared at Regulus, then hissed,

"You are a crazy politician Ravenclaw with the sheer bloody mindedness of a Gryffindor and the sneaky cunning of a Slytherin who should have been a spell crafter. Oh, why did we make you the politician of the family?" The snake, a beautiful specimen of the garden variety, tilted her head.

"You are a very angry man, Speaker. Why?" she asked. Sirius paled.

"Oh Godric Gryffindor in Helga's fluffy yellow bath robe. I'm a parslemouth now," he muttered... er... hissed softly. Regulus grinned and knelt down beside his conjured snake.

"Well, it seems we've broken my dear brother. Well done, my pretty, well done indeed," he said with a grin. Sirius glared at his brother.

"Bite him. Please," he hissed. Seeing the murderous look on his brother's face, Regulus quickly dispelled the snake, then vanished. "Drat! I really need to get him to teach me that!" Sirius said, stomping around the flat. Regulus, meanwhile, was updating his will at Gringotts. The goblins were mildly amused as they watched the young man mutter and scribble then look over his shoulder before muttering something that sounded like 'he won't really kill me would him?' It was only five minutes before Regulus left the bank, but to the young man, it felt a lot longer. And then... Sirius Black walked in, sipping a frosted lemonade, and just stared at his brother. Regulus gulped. Sirius slurped. Regulus twitched. Sirius grinned around his straw. Pulling it form his mouth, he used it to point at his brother. "I win," he said, then turned on his heel and walked out. Sharpsword, who had seen the whole thing, couldn't hold back a snort.

"Sirius Black, always interesting, that one," he said before walking off. Regulus sagged back against the desk he had been using.

"I really thought he was going to kill me for a while there," he said, voice weak from lack of air. The goblins shook their heads and went back to their ledgers. The show was over, but it had given them valuable information. The Blacks were an interesting family, and one to watch.

/*/

Things were changing in England, but only a small percentage of the population knew about it. And it all started with one young man from a very old House by the name of Black. After that one young man, only about twenty years old, came another two years older. His brother, Sirius. Sirius had taken Headship of an ancient House. Or rather, Lordship. And what did this ancient Lord do? He ran a joke shop called Padfoot's Gambols. And then, as if all that wasn't enough, James Potter was supporting the Black family! And on top of that, Hogwarts was undergoing an overhaul, Albus Dumbledore was removed from the Headmaster position, and it was looking like his controlling tendencies were about to see him jobless! For some, this was not something to worry about, but for Albus Percival Wulfric Brian Dumbledore, it was most certainly something to worry, or even be upset, about. As for the Death Eaters, they could care less about Dumbledore's problems. They were the ones being hunted, and they couldn't even hide their Mark! Not with that stupid law that Black had gotten passed. And both Blacks and Potter had gotten to Fudge. He wasn't as pliable as before and thus, could not be used as a puppet. The Dark had lost, the Gray had won, and the Light was back with a vengeance. The Blacks were back, and they didn't look like they'd be leaving any time soon
