Hi, this is my first fic. Please R&R.

Disclaimer: I don't own it or anything, Cahterine is mine though and the idea of the GHS. Please don't sue me Joanne. I'm just a poor student.

HOPE YOU ENJOY IT!

The GHS.

'Sirius, you can't leave her now. She needs us, we're all she's got.' Remus Lupin shouted down the corridor of Hogwarts, he stood outside the doors of the hospital wing, his robes, shabby as usual, covered in dried blood. He stared at the retreating back of his best friend, Sirius Black, as he strode down the corridor away from him. 'Sirius...' Sirius turned.

'No, Remus, I can't deal with this at the moment. I'm going to go and see Harry, he needs me. She has you.'

'Harry needs you,' Remus called in disbelief, 'Harry has a broken wrist, that is it, a fucking broken wrist. Catherine, your daughter, has been in a fucking asylum for a year, and you need to go to Harry. Are you just going to leave her? Am I supposed to tell her that her father doesn't care?'

'Remus, I can't deal with this. Harry wants me. She doesn't.'

'Sirius, she doesn't know what she wants. All she knows at the moment is that we left her there for a year. A FUCKING YEAR. We left her there so that you wouldn't have to go back to Azkaban. Although, I'm betting you would have handed your self in if Harry asked you to. Fudge is gone. Dumbledore took the Minister for Magic job, you got a pardon. You no longer have to hide. Are you going to keep hiding to stay away from her?'

'If that's what it takes. I can't just deal with this. She was kept out of our world for precisely this reason. As soon as the Ministry declared the GHS an enemy, we decided to keep her safe. We decided to keep her out of this world, we couldn't have her presenting at Hogwarts the way she was, she was privately tutored and kept away from me and everyone.' Sirius began to walk back towards Remus, shouting. His voice getting higher and higher. 'I love her Remus, and that is precisely why I am staying away from her. We don't know what they told her in there. It could have been anything. And, I can't just drop a daughter on Harry after this time!'

'Harry will understand...' Neither of them had noticed Harry walking up the stairs behind Sirius. He called.

'What will I understand? Sirius, what's going on?' He walked slowly down the corridor, ' why are you arguing?'

'Harry, it's nothing for you to worry about. Just go back to the main hall and I'll be down in a minute. Ok.' Sirius's voice was frought with desperation.

'Sirius, you have to tell him. Hermione's going to have to be found at some point and then it will all come out.' The door to the infirmary creaked as it opened slowly. Remus spun round on his heels and stopped, gazing at the slim female form that had just stepped out. She wore loose fitting white and purple pyjamas and had a bandage covering her right arm.

'Catherine, you should be resting. I'll take you back in.' Lupin's voice was calm as he began to walk towards the figure.

'Sirius, you never came to see me. Where you just coming? I, uh, heard raised voices and only had time to magic up these,' she indicated the pyjamas, 'I hope they are ok?' She stumbled, clearly weak, and Remus ran to her and caught her. Twirling his wand from his pocket, he magicked up a chair and sat her on it slowly. 'Who's the young man?' She pointed at Harry. Her breath was ragged and she fought to sit up straight, eventually resting her elbows on her knees and propping her self up.

'Catherine, I meant to come and see you. I was going to come and see you, but I had to deal with some stuff first. You should really go back to bed, you don't look well.' Black stumbled over his words and began to move almost as if to cover Harry from view.

'Really, don't look well,' she looked at Remus, 'can't think why that would be?' Laughing nervously, she once again indicated Harry. 'Well, arn't you going to introduce me?'

'Uh, Catherine, this is... this is Harry Potter. You remember, the night with you-know-who? He helped you right?' Sirius moved even more as if to completely block Harry from both Remus and Catherine.

'Yeah, I remember. Hi, I don't think we talked properly before. My name is Catherine Frost, I helped a little.' Sarcasm began to creep into her voice, and she sat up almost as if hearing Harry's name had given her extra strength.

'Yeah, I remember too, just wondering, why are you here? And not at St. Mungo's, I mean you're not a student, or a teacher.' Harry was looking at Sirius inquisitively as he finished talking.

Catherine stood, she wobbled slightly and Remus steadied her, 'Dumbledore had me brought here, brilliant man Dumbledore. I'm glad he got the Minister for magic position, he's much better than that Fudge character. I hear they gave you the Order of Merlin, First class for your defeat of the dark lord. I commend you. Although I have to say, it's sickening.' She spat the last phrase as venom began to creep into her voice.

'Catherine, lets leave this. You should fully recover, before...'

'Be quiet Remus. This has to be said, he has to know. Talking of 'knowing'. Does he know my familial position with regard to this little gathered group? Huh, Sirius?' She cocked her head to the side and her stance straightened.

'No, Catherine. He doesn't know. And if I have my way he won't know, because he doesn't need to know...' Sirius tried to hold himself rigid but Catherine's glance wore him down.

'In the same way as I didn't need to know, that you were going to leave me alone and hide away from me. Harry, your godfather will probably try and tell you that I am a friend. Bollocks. I am his illegitamate daughter, the same age as you and I killed Lord Voldemort. Not you. Me.'

'Listen, Catherine, are you insane or something? Sirius would have told me, wouldn't you? Sirius?' Harry looked at Sirius, who seemed to shrink away.

'Harry, I was going to tell you. Things got in the way.'

'Sirius, is she a death eater or something? You're all scared of her and there's really no point. I mean what does she mean, she killed Voldemort?'

'That much power doesn't just dissapate. It has to be taken away. And only one lifeform can do that. A GHS, Grand High Sorceress. Or for those not in the know, me. So, sorry to burst your bubble, but I weakened him and I killed him. You just got the benefits. So, whilst you were getting the nice front page spread in the Daily prophet and your nice little presentation at the ministry. I was drugged, gloved and thrown in a muggle asylum to rot. S'not really fair, when you think about it. You must agree? And do you want to know what? Of course you do. Daddy dearest here, was only too happy to leave me there. And d'you wanna know why? All because he was worried for his golden boy.' Her hand had balled into a fist. Which she pulled open to reveal a glowing red ball of fire. She began to play with it, tossing it from one hand to the other and back.

'Whoa...' The assembled crowd turned to the stairs and saw Ron Weasley stood there watching the fireball roll back and forth. 'Harry, what's going on?'

'Ron, go tell Hermione to come up and keep everyone away from this corridor.' Lupin called from his place behind Catherine.

'Huh...'

'Ron, go.' He turned and ran away down the stairs.

'Remus, honey, are you trying to rat me out?' Catherine turned, the fire still rolling from one hand to the other never breaking its rhythm.

'Catherine, you need help. We are so sorry for what we did. Hermione can help you. She's your apprentice. Just wait and calm down. And how about putting the fire out?' Remus moved slowly so he stood between Catherine and, Harry and Sirius. She followed him.

Meanwhile, Ron had found Hermione, 'Hermione, Hermione.'

'What is it Ron? I thought you went to find Harry?' She looked boredly up at him from the chair in the main hall.

'Professor Lupin told me to get you. There's a mad strange, quite gourgeous, woman holding them all up there and she's playing with fireballs. It didn't look good.' Hermione stood, the book on her lap falling to the floor.

'Catherine, but it can't be.' She ran off, Ron following her with the intentions of blocking off the corridor and trying to work out a way of asking this mad woman on a date. Hermione took the corners with surprising deftness and sprinted up the stairs.

She appeared at the top of the stairs in time to see Remus take the fireball out of Catherine's hands. And watch it extinguish as it hit the floor.

'Catherine, come on lets get you back to bed.' Hermione didn't know how she knew, but she kew everything that had happened to Catherine during her year long stint in the asylum. In mesmerising detail. She was sickened to think that it was all carried out so her friend could comfortably live with the adoration of millions of witches and wizards the world over. Carried out by a man she had at first championed as just a bit slow and not really hiding things from the public. She was now personally glad that he had been booted out of office and Dumbledore had taken the position.

'You know. You know what happened.' It wasn't a question it was a statement. Catherine had told her it all in a split second when their eyes had first met. The strain was too much and Catherine fell to the floor breaking down as wave after wave of memories flooded over her. She wondered how she could ever tell Remus what had happened. He knew some of it. Hermione ran over and sat next to her. Spying the bandage she pulled it of. It easily fell away to reveal a tight black glove with metal prongs attatched to the top that were imbedded into the skin. A glove of Atracne, designed to keep the GHS under control. They could do basic magic, but the fireball had been more of a scare tactic, it was about as hot as tepid water. Hermione ran her finger down the side of the glove and the metal spines retracted and the glove slid away.

Remus leant over and him and Hermione helped Catherine to her feet and back into the waiting bed in the hospital wing. Laying her head on the pillow as she fell asleep.
