See, I saw all these stories where Sirius has a daughter who befriends Harry or Draco, so I thought, what if he had a son? Not very original, I know, but please bear with me as I have never tried this sort of thing before. Basically this story will follow Corvus (real constellation, look it up) through first year with Harry and the gang.

I've also twisted a few things here for plot purposes. Walburga Black supposedly died soon after Regulus, right? At least that's what I've read, but I need her alive here, so I've made her old and sickly, but still hanging in there. I also gave the Blacks another house elf. Also, Corvus' mother is an OC, and so, obviously, is Corvus. If there are any issues, please tell me so I can improve!

Story will mostly centre around Corvus for a chapter or two, but then they're at Hogwarts so it'll focus more around Harry. Of course, that's after the prologue. Hang in there for your cliché goodness, guys. Also, I'm not sure how loyal Labradors are, but I'm assuming they're pretty dang loyal. So please don't shoot me. And at least try to enjoy my shoddy, pathetic excuse for a prologue.

Disclaimer: If I owned Harry Potter... well, I don't think you want to know. Trust me XD But I don't DX

James Potter was a lucky man. He had the world's wittiest and most wonderful wife, a best friend who was literally as loyal as a Labrador and a knack for alliteration. He was young, handsome, popular, filthy rich, intelligent, and most importantly, he had the heart of a lion. James Potter would have had it made, if there wasn't a war on.

You see, James was a member of the Order of the Phoenix, a group fighting the evil forces of Lord Voldemort, the Death Eaters. After all, Voldemort was not a particularly nice man- nor was he young, and he certainly didn't have the heart of a lion. No, Voldemort had an ideal. He wished to purge the world of its non-magical inhabitants (thus unwittingly ensuring that within two centuries the entire human race would have become extinct due to the common cold, and all have around sixteen toes and fingers- he didn't really plan much ahead). James was dedicated to stopping this evil, alongside his wife, Lily, and his best friends, Sirius Black, Remus Lupin and Peter Pettigrew (who later turned out to be a big fat traitor who should be fed to the nearest alley cat on sight).

Anyway, an applicant for the position of Divination teacher at James' old school, Hogwarts, made a thoroughly interesting prophecy that directly applied to James' newborn son, Harry, and the Potters were forced into hiding in order to protect the child. In an attempt to get Voldemort to go away, they placed a charm on their home- only their Secret Keeper could divulge their whereabouts. It was unfortunate, then, that they gave their friend Peter the job of Secret Keeper as opposed to their first choice, James' all-time best friend (and favourite mutt) Sirius, because Peter scurried straight off to Voldemort and got both James and Lily killed, as well as Sirius thrown in the wizard prison Azkaban and Remus nearing a mental breakdown.

But you know that story. The story we shall look at now, is the story of a young woman named Isabel Robinson. She was a sassy, attractive woman, intelligent, but definitely ruled by her emotions. She had been to Hogwarts with James, Lily, Sirius, Remus and Peter, who had been known as the popular kids. She was popular, too, just not that popular. She'd dated Sirius a few times, who was infatuated with her, though he pretended not to be, ladies man that he was.

But Isabel was in love with James.

Of course, she knew that James loved Lily. The two of them were meant for each other, even she could see that, even though she prayed every night that he'd come to her door and not Lily's. Needless to say, it never happened, and the day after Lily and James' engagement was announced, she turned to her only source of comfort- the man she knew would do anything for her, Sirius Black.

Time passed and the new Mrs Black found herself pregnant. She liked to pretend it was James' baby, and was over the moon when Sirius asked her if it would be alright if James and Lily were the godparents. Soon after, Lily became pregnant. Isabel entertained daydreams of switching the children and running away with the little piece of James that was his child. They'd never know.

She never found out whether she had the guts to go through with it or not because James' and Lily went into hiding. Sirius told her their plan was foolproof, that James would be fine. Isabel nursed her baby through its eighteen months of life during this time. He was pale, like Isabel, but had his father's grey eyes and thick black hair. She could tell he'd be handsome like Sirius when he was older, though his features would be more delicate than his father's. Perhaps he and Harry would be friends. Then she could see James whenever she liked.

On October 31st, 1981, Isabel received the news that James and Lily had been murdered by Voldemort and the baby had been sent to Lily's relatives. Sirius had been the Secret Keeper. Sirius had betrayed her. She left her child- no, his child, a foul, loathsome thing- on the doorstep of Sirius' parents' house. She hoped the thing's grandmother would kill it. Isabel then attempted suicide and was taken to St Mungo's for life-saving treatment- and therapy.

The child was found by Kreacher the House Elf the next morning. Kreacher loved his mistress dearly, so he immediately placed the baby in the drawing room. Following this, he hurried up the stairs to his mistress' room. She demanded to see the baby, even if it was the child of her blood traitor son who had always hated Kreacher.

And so, Corvus Remus Regulus Black was raised by his grandmother, Walburga Black, at Number Twelve Grimmauld Place, believing his father was a murderer and his mother a madwoman.

About Corvus' house, quickly... For plot reasons I will probably put him in Gryffindor but that is subject to change if you get your say in quick enough. One thing I will say though- he'll either go in Ravenclaw or Gryffindor, unless you can make a really convincing case for the good ol' Hufflepuffs or those deliciously nasty Slytherins. And I'm taking votes for whether this should be slash or not- I'm not big on writing romance but I can throw in some fluff if you want me to.

Read and review please! I can't improve without you!
