AN: Okay, this will be my first attempt of a serious Harry Potter fanfiction! I've spent time thinking of the idea and had a few rough drafts, and this is what I came up with! There won't be any incest except for a few implications, although with the Blacks, no incest is almost impossible, so I may or may not do something about that. I'm unsure about the rating staying teen, but I'll figure it out later! This story has some MAJOR AND I MEAN major AU moments, but it follows the basic Marauders-era plot ad drama, so bear with me. I'm also looking for a beta, so if anyone is interested, y'know what to do. PM me. Please read and review!

12 Grimmauld Place

''That's it!'' Exclaimed Sirius, storming into Regulus' room, his gray eyes somewhat teary, ''I'm leaving! I have had it with these, ignorant… imbecilic… ignorant… Excuses for parents!'' He paced around his brother's bed, whose occupant had just begun to wake up,

''Eh- wha', Sirius?'' Mumbled Regulus, his eyes showing a mixture of exhaustion and confusion. His older brother ignored him and continued his ranting,

''I mean, what kind of mother says, 'It was bad enough he wasn't put in Slytherin, but now he has a Mudblood friend!'?'' Sirius kicked the leg of Regulus's bed, sending vibrations through the wood.

Regulus was now just a bit away from being fully awake. He sat up and observed his furious brother, who was now standing with only one leg, face contorted in seething rage and pain as he rubbed his hurting foot,

''Sirius, what the hell is it now?'' Asked Regulus, resting his elbows on his knees. The curtains were pulling themselves apart, letting sunlight shine through the somewhat grimy windows, and Regulus presumed that he would have been awoken with or without his brother's disruption.

Sirius was now back on two feet, ready to continue his rage, although he paced a bit stiffer this time.

''It's them, Reg!'' Regulus massaged his eyes with his thumb and index finger, knowing exactly what them was, ''Mum and dad, no- Walburga and Orion- are the most irritating individuals who I have ever had the misfortune of knowing!'' He aimed another kick at the bed, but seemed to rethink it.

''What'd you do?'' Asked Regulus, leaning out of the bed, trying to make his feet touch the ground.

Sirius shot him a look of minute outrage, ''What do you mean, 'What'd you do?'?'' When Regulus didn't answer, Sirius threw his hands up in disbelief, ''I didn't do anything! I just walked in and Mu- Walburga- started to speak to me about Durmstrang. Durmstrang, Reg! That school practically shouts, 'ALL FUTURE DARK LORDS, COME HERE!'!''

Regulus shrugged helplessly as he left his bed and began searching through his wardrobe, looking for something to wear after he took his bath.

Sirius huffed and collapsed on the bed, (the sheets were just about to make themselves) his face looking defeated.

''I'm tired, Reg.'' He muttered, twirling his fingers in his waving hair, ''I'm tired of all the rows, the arrangements, I'm tired of everything.''

Regulus picked out a green linen robe with the initials, R.B., twinkling on the breast pocket. He held it out, observing the fabric for any stains that may have married it. After he was satisfied, h laid it down on Sirius's exhausted body. How brother didn't move under the robe, but did mumble,

''Arse.''

Regulus sat down in the seat next to his end table, and drummed his fingers upon the surface, ''Why can't you just pretend?''

Sirius immediately bolted upright, letting the robe fall to ground,

''Pretend?'' He repeated, his voice radiating sarcasm, ''Oh, that's good. I'll just walk back downstairs and say, 'Gee, sorry Walur- Mum- about acting like a child for the last five years, I'll now adopt the family tradition of insulting any muggle-born that has the nerve to look at me, Hell, I'll even convince Pofessor to transfer me to Slytherin!'.''

Regulus ran his hand through his hair and mumbled, ''That would work. Pick up my robe, please.'' Sirius complied and rested the robe over himself as he lay back on the bed once more.

The brothers didn't exchange any words after that; Regulus grabbed his towel which was resting on the back of his bedpost, and left to the bathroom.

Sirius let out a huge breath through the robe, sighing as the door to the bathroom closed. He bolted upright, got to his feet, and let the robe lie on Regulus's bed, searching for something to do.

There was nothing to fix or clean that Regulus didn't. The room was cast with an eerie green as the result of Regulus draping almost every inch with banners of the Slytherin house. There was not a speck of dust anywhere in the room due to Kreacher's excessive cleaning (Sirius noted that his room never looked this clean, even when he tried his best to be kind to the elf.)

Two mahogany colored wardrobes flanked each side of the four-poster bed, while an end table lay at the foot. Hanging above the bed was the Black family crest, followed by, Toujours Pur.

It was the collection of newspaper cuttings under the crest that caught Sirius's attention.

He moved closer up the bed to have a better look,

''Bloody hell, Reg.''

THE ''DEATH EATERS'' STRIKE AGAIN

Once again, the society known only as the Death Eaters, have unleashed another series of furious attacks led by He-Who-Must-Not-Be-Named.

The latest confirmed victims are:

Sirius stopped reading and rushed out of the bed as his brother stepped back into the room, curly hair wet and his slender body covered with a towel,

''Would you mind?'' He asked Sirius, hands on his hips. When Sirius did not move to leave.

Regulus sighed and dropped his towel on the floor.

Sirius covered his eyes with a hand and muttered,

''Didn't need to see that, Reg.''

Regulus couldn't suppress a grin as he reached for his underwear, which lay in his wardrobe. He put in on, walked over to his bed, and grabbed the robe he had laid out earlier,

''So, prepared for Hogwarts tomorrow?'' Sirius didn't answer, but Regulus could see him walking towards the door out of the corner of his eye. The younger brother sighed and put his arm into the sleeves of his robe, not bothering to wear an undershirt.

Just before Sirius exited, he turned around and spoke to Regulus in one of the most solemn voices that the latter had ever heard,

''I don't know why you're following him. Do you know what he did to the Bekke's?''

Regulus sighed and put both arms behind his neck, contemplating how to respond without sounding heartless,

''You mean Jo Bekke and her father Oswald Bekke?'' When Sirius did not reply, Regulus assumed that he was correct, ''I don't think their deaths were a great change in anyone's lives. Jo was an unintelligent whore, and Oswald was a git.

Sirius left, closing the door with a loud bang behind him.

The Hogwarts Express

Regulus watched as Platform 9¾ slowly disappeared from view of his window in the compartment. A chocolate frog landed on his lap, and he looked to his side.

Amycus Carrow was staring awkwardly at him, hands covered in chocolate, and his lap filled with wrappers.

''Yer gonna eat that, lad?'' Carrow pointed to the chocolate frog in Regulus's lap. Regulus shook his head and allowed Amycus to pick up the sweet.

Regulus returned to staring out the window. Any signs of urban life had been replaced by the greenest trees and lush grass that were part of the endless fields of the countryside. Regulus found it hard not to drift into a reverie full of unicorns, daisies, and-,

''Reg, watch out!'' Regulus barely had time to look as an Exploding Snap card flew at him. It landed on the right side of his face, and Regulus it his head against the window, earning laughter from his companions in the booth.

Rubbing his reddening cheek, Regulus swiftly took out his wand and pointed it at Antonin Dolohov, who was sitting across from him.

''Care to tell me why you aimed that card at me?''

Dolohov's face was twisted in uncertainty and mock outrage, ''What do you mean?'' He exclaimed, his hand reaching for his pocket, which held his wand, ''It was an accident.

Regulus stared long and hard at his dark-haired friend, and both of them exchanged looks of mirth. The others in the booth saw this exchange, and instantly the tension melted.

''I really thought you two would end the rows and start dueling to the death.'' Sighed an exasperated Rowle, whose massive frame earned him his own special seat on the ground near the booth's door. He cracked his neck, trying to rid himself of the aches that were already starting to creep around his body.

Rudolphus Lestrange murmured something in agreement from the seat near the entrance of the booth, eyes dreamy and his thoughts obviously occupied by his current girlfriend, Bellatrix Black, who was in the next compartment with her own friends.

The three other boys in the booth exchanged knowing glances, getting prepared to stretch their vocal chords to sing the song that had been christened to poor Rudolphus in sixth year when he had told Bellatrix that he had loved her.

Rudolphus shot them all deadly looks and returned to looking at pictures of himself and Bellatrix that were taken the previous year.

''Aw, c'mon mate, we weren't going to actually sing it,'' Rowle spoke in a teasing tone, ''I mean, the song is ridiculous, really. Who would want to sing, 'Lestrange liked Black, Lestrange liked Black, and everyone knew that he liked her for her rack.'…'' By now the other boys had begun to join in, and Rudolphus buried his face into his palms.

They shagged in Potions

And he got lots of lotion

She got on her knees

And she begged him please

And that's when Slughorn-.''

''Stop!'' Shouted Rudolphus angrily, finally halting his friends from continuing the song. He shot glares at all of them and got up from his seat swiftly.

''Goin' ter the loo?'' Cackled Amycus hellishly as he stretched back and let his legs rest on Rudolphus' seat. He leaned in when the latter was gone and whispered, ''Figure he went ter see Bellatrix?''

Regulus let out a dry laugh, ''Yeah right. She has him twisted around her fingers. You don't think she actually likes him, do you?'' When none of the boys answered, Regulus massaged his eyes with his index finger and thumb, ''Look at what she did to Igor in Fifth year! He was in Seventh and had to leave Hogwarts before Graduation!''

''Igor was a prick.'' Mumbled Rowle, twirling his hair through his fingers, ''He deserved what came to him.''

''Even so,'' Replied Regulus, ''She destroyed his reputation here, possibly in the whole Wizarding world.''

''I heard he moved ter Durmstrang.'' Squeaked Amycus, eager to add to the conversation as the train began to slow. Regulus looked outside the booth window and was slightly surprised how quickly evening had come. Already the moon was emerging and the forests surrounding the land of Hogwarts had grown dark with menace.

As the platform came into view, Regulus turned his gaze to Dolohov, who had remained silent for the pass several minutes,

''You alright?''

Dolohov did not answer, but instead rolled up the sleeve of his left arm, revealing the burned Mark.

Everyone in the compartment held their breath, not realizing that they were holding it.

Finally, after what seemed like an eternity, Rowle finally moved closer to Dolohov and whispered,

''Is it… Is it r-real?''

Dolohov nodded and quickly rolled down his sleeve as the train stopped,

''Come on, I'll tell you all later.'' He stood up in haste and left the compartment. The other boys shot looks at each other and stood up to follow as well.

''Wait!'' Cried Amycus, squeezing out of the booth after Regulus had done so, ''Shouldn't we wait for Rudolphus?''

Rowle dismissed this with a wave of his hand, ''He would kill us if we told him.''

The four boys walked down the hall in the crowd of bustling students, pushing their way past first years. Regulus felt a hand grip his and he looked over his shoulder swiftly.

''Narcissa…'' Regulus didn't have time to blush before being sucked back into the crowd, Narcissa now lost to him.

Cursing under his breath, Regulus found himself at the steps leading out of the Hogwarts Express. He stepped out and shivered, the night making the air colder than it had been earlier.

Amycus tugged Regulus's sleeve,

''Come on, this way!'' Regulus saw his three friends making their way to the back of the large group of students, where most of the Slytherins stood.

As he made his way to them, he caught a flash of wavy hair and swiftly turned to find Sirius staring at him.

''What is it?'' Hisses Regulus, trying his best not to sound like he enjoyed his brother's presence, ''What do you want?''

Sirius stared at his brother for a swift second before turning his back and joining his fellow Gryffindors. Regulus gaped in some form of shock, seeing as how Sirius had never turned his back on him before. This lasted only a moment before he slowly closed his mouth, turned his back, and walked towards his friends

AN: Well, there it is. The first chapter of The Anti-Marauders! As you can see I destroyed many birthdates as you may have noticed with the slight AU. I do plan on having a sex scene, but I'm unsure if changing the rating beforehand will be necessary. Anyway, PLEASE REVIEW! It only takes a minute. Those reviews make me know that I have something worth writing.
