So this used to be the story, 'My Beautiful warrior', I tried to keep to the original as much as possible with a few tweaks after getting way to into making the timelines perfect.
Disclaimer, all character belong to JK Rowling and the Harry potter franchise.

Enjoy.

She lay on the bed with the curtains drawn feigning sleep and listening intently. She was waiting. A high pitched scream erupted across the dormitories and dungeons, perhaps the whole castle heard. The other girls in her room stirred, drawing curtains and feet hitting the floors filled the silence after the scream.
'What was that?' One asked.
'Who was that?' said another.

She smiled to herself, slowly rising and drawing back the drapes, 'I have no idea but I was thoroughly enjoying my sleep' the other girls looked towards her. She moved to prop herself up on her elbow and waited. There was noise growing outside their door and then it burst open.
A short, pudgy...green girl marched in. 'YOU DID THIS BLACK, I KNOW YOU DID...WHAT HAVE YOU DONE TO ME!' She screeched at her.
Bellatrix simply raised an eyebrow. It wasn't long before a flustered professor came into the room.
'What in Merlin's beard is going on here girls?'
The green girl turned to the professor and pointed back at Bellatrix. 'Professor she did this, I don't know how but I just know she did!'

Bellatrix sighed, 'Professor, I haven't the slightest idea what Dolores is on about. I have been sleeping until rudely awoken, and during the day surrounded by others constantly she must be mistaken', her face feigned innocence, it came so easily to her. The professor looked at both the girls. 'Dolores, she has a point, evidently you are mistaken, now come dear we'll assess the damage in the hospital and let these girls sleep' then led the infuriated green girl out of the room shutting the door.

Silence fell on the girls. 'Bellatrix, did you?'
She simply closed her draped and left them to speculate.
'Of course she did it, Only Bellatrix could pull something off like that and her and Dolores have been at each other since the start of term!'
'But how did she get away with it, jinxing a student?'
'Bellatrix would jinx a teacher if they crossed her and get away with it I'm sure' I was in a hushed whisper and then a small quiet giggle began between the girls before they finally settled.

Sitting in the train compartment Bellatrix looked out at the bustling platform, watching as a green student walked past, still looking infuriated. 'How long will that last Bellatrix?' one of the girls asked, she smiled to herself.
'I have no idea'
A chuckle followed and laughter from the other girls. The train pulled out of Hogsmead and into rolling countryside, heading to London.

Platform 9 ¾ was clouded in steam as students piled off the train to greet parents and siblings. She spotted her parents waiting, chatting with a pale haired man. She walked over, greeting her mother and father and Abraxas Malfoy.
'Finally finished then Bellatrix' He said appraisingly.
She nodded, looking at the approaching Andromeda, followed by Narcissa and Lucius. 'Two years left for you though Lucius, but I'm sure Cissy will keep you company in my absence'
'Bellatrix, if you have nothing more to say, I suggest you go home', her mother's voice cut her smirk.
'Of course mother', she looked to her father who inclined his head and passed a ghost of a smile, she returned it and grinned wickedly as the green Dolores walked passed. She disapparated and left her family and the Malfoys on the platform.

She arrived in Manor Noire, making her way up the grand stair case to the west wing where her room was, her trunk and things were already waiting and unpacked. Books returned to shelves and trinkets and trophies were placed in draws or around her room, the house elves were on form today it seemed. She placed herself on the edge of her bed, sighing and closing her eyes, she had finally left school and could do what she wished. Her eyes snapped open, but she would be made to go to all sorts of dances and such, meeting men who her parents would push at her...A husband. She couldn't stand the thought of marrying any man she had met so far, and there were too few purebloods around, a limited choice. She hated the thought of wasting her life, a trophy wife, doing nothing.

Not long after her thoughts had begun to wander to her new freedom, the rest of the Black family arrived, all going their separate ways before dinner, and once that was over she headed back to her room, reaching the stairs she began to ascend.
'Bellatrix'. Her father's voice called to her. He stood in the entrance of his study, waiting for her. Once she entered and took her seat he closed the door, placing himself in his plush chair in front of her, behind a large ebony desk littered with various pieces of parchment, quills, empty glasses and mugs and a paper weight with the black family crest engraved upon it..

'Bellatrix…' He sighed, 'Such a shame you were not born a boy. You would have made a perfect heir.'
Bellatrix frowned she had heard this all before during many heated discussions about her future.
'However, your duty to this house and family are thus, you will marry a suitable husband chosen by myself and your mother, I am sure you know this by now.'
She looked up at him. 'Yes father but...'
Now Cygnus Black was never the man to challenge, but like father like daughter.
'But what?'
'I want to do more than be some trophy wife. I want to make myself useful, not just to bare children' She said, disgust in her voice.
'Bellatrix, you are a woman in pureblood society, you know where you stand'
'I hate where I stand'. Her voice increased. 'Why can't I choose my on husband, or not marry at all! I'll waste away not being able to do as I please and use my skills…' 'Bellatrix, you will not raise you voice to me!' he said through gritted teeth, he didn't want a full blown quarrel with her.
She was worked up now, she wouldn't stop just yet. 'I will not waste my life being some Trophy to a waste of man who doesn't deserve me!'
'BELLATRIX! You will cease this infernal shouting this instant!'

She let out a breath, readying herself to say more, then didn't. She sat herself back down, and her father followed suit. 'Bellatrix, my Bella, no man will ever be worthy for you, I regret to send you for such a life, however it is as it is and you are a woman'
'Then don't', she said, quietly.

He shot her a stern look and she looked at the desk top. 'Remember that, I expect you to attend any dances and the like with your mother, keep up appearances. It seems Narcissa has her heart set on Lucius, a union which I am in favour of, as it is he is similarly inclined'. He paused, Bellatrix simply nodded. Silence fell as he took out a crystal glass and decanter, pouring himself a drink.

Bellatrix looked at the latest Daily Prophet, reading the headline, more muggle killings and a mudblood too. Her father watched her, 'These followers of the rumoured Dark Lord have been keeping busy', he said casually.

'More killings, and a mudblood, so they have finally gotten round to getting rid of that kind…' She said nonchalantly.

'Indeed' He replied.

'You're one of them aren't you father?' She looked up at him, his face passive. 'I've heard whispers and rumour, and what the prophet mumbles about. They say the Dark Lord is raising forces to take over, he has the support of many purebloods…like us yes?' He watched his eldest daughter scanning the paper.

'You seem to know a great deal on this subject Bella, and do you support what is happening?' He took a sip of his drink.

'I have my...Sources...and yes' She answered, skilfully.
He smiled at her taking another sip. 'You can go now Bellatrix', it was so blunt an order but she followed it, only for her father, and she left the room.

Cygnus looked down at the paper, the image clearly showing the ghostly Dark Mark, swirling among the clouds. He took one last sip of the fiery liquid and placed his glass over it.

And so, a revamped chapter one, hope its better and my reading through over and over has fix all the little mistakes. R&R, will hopefully be posting regularly with this story.
