This story was one which came about when i started reading the Genevieve omnibus (good books i really do recommend them) and as i was also reading Deathly Hallows (i got the books on the same day) crossover ideas began to enter my mind... i really need to stop reading more than one book at a time, i only get more ideas which make my head hurt... anyway back on topic, This had a Lahmian Vampire thrown into the world of Harry Potter and she naturally stumbles across him and uses him to help her return to her own dimension with the agreement of her training him. it also included a marriage contract with Susan Bones since she was a character that had always interested me but i never did anything with said character.

Prologue

She stood in the darkness of the streets looking around at her unfamiliar surroundings the buildings were more advanced and sturdier then any that she had seen in the Empire or the Elven Kingdom which she had briefly visited before her change. There were horseless chariots every where around the street. She looked up to see the torches that lit the street not the familiar torches that she was used to seeing.

The street itself was deadly quiet as she stepped along it there was no one about, no guards patrolling the streets no sign of life what so ever. She cursed her luck, that there was no one around the hunger was gnawing at her, she had not fed for days.

Continuing her walk across the streets her keen senses heard a creak from the gates to her left and she spun around the gate that she could have sworn was closed was now swinging open in the gentle summer breeze. She walked over to the gate and silently stepped in the gate creaking shut behind her. She paused as she sensed something familiar in the air.

The taste of magic.

It was different to what she had come up against before but that was to be expected in this different location, where ever here was. Several voices echoed different words that she was unfamiliar with the words used but heard the cries of pain from a different person. She sneaked forwards at a slightly faster rate and saw a group of four people surrounding a child of 15 each pointing sticks at him… the child was writhing in pain on the floor and she realised the sticks must have been channelling the magic. She saw the child drop to the floor his body twitching slightly and they continued what ever spell they were casting.

Normally she wouldn't have cared if they were torturing someone but this was a child, to torture a child that was reprehensible.

Moving through the shadows silently and quickly she was a mere 5 feet away from them when they first noticed her.

The three turned to face her and laughed. "Stick around muggle we will happily get to you next." A female stated as she readied her stick.

"And we know how to treat people of your class." A male sneered behind his mask and the witch begun to mutter the words for a spell and that was all the sign that she needed as she closed the distance between her and the witch before she had even finished a syllable.

"I do not know what you are talking about." She muttered as she pulled out a jewel encrusted dagger and sliced open the throat of the witch who's eyes which were visible behind the mask widened in shock as she dropped the wand and clutched at her throat as blood trickled from the wound. She spun round and threw the dagger at the second, the blade pierced the mask and he dropped to the floor. The third growled in anger and she laughed and signalled for him to wait.

"Why fight me, when you can fight your friends?" She asked and gestured with her hands and the two who had just died slowly dragged themselves up. "I do hate zombies but when you have a situation available to use… well why not?" She asked and the zombies shuffled towards the Death Eater who was frozen in terror, they reached him and forced him down as they clawed and tore chunks of flesh off of him with their teeth.

She ignored his screams as he was killed and turned to the fourth one who had dropped his wand and stood there in surprise and horror as she ran forwards and grabbed him, pulling his head to the side he tried to fight back but she held onto him with an iron grip and bit down on his neck spilling his life fluid and beginning to drink.

When she was finished she resurrected the body and turned to the boy who now lay on the floor in the foetal position she was to kill him, to prevent witnesses. She walked over to him and knelt down brushing the hair from his face and studying the lightning bolt. "He might be of use to me, living I have shelter in this strange world, dead he is just another corpse." She stated and stepped back. "But to do this I shall need to stay secret for now, to all bar him." Slowly her shape changed and she shrunk and took the form of a small black cat and curled up next to the boy. With a last thought she ordered the zombies to exit the town and collapse somewhere where people wouldn't find them.

Harry awoke before dawn, the first thought that came to his mind was why was he sleeping in the middle of the park. His second thought was why was he aching so much?

Then he remembered, Death Eaters had attacked him last night!

Looking around Harry saw no trace of them, the only sign of a disturbance was a small pool of blood and bits of skin that looked like it had been pulled off. Harry looked slightly green and resisted the urge to throw up at the sight and pulled himself shakily to his feet using the old climbing frame that was only just standing after the punishment that Dudley and his gang had dealt to it over the years.

A noise cut through the silence and Harry looked around in confusion and fear thinking the Death Eaters might have returned.

The noise came again and Harry looked around still seeing nothing kept turning to try and pinpoint it.

A clawing on his leg caught his attention and Harry looked down to see a small black cat. It meowed at him and rubbed against his leg and Harry reached down scratching behind its ear and causing the cat to purr. "The Dursley's are going to kill me…" Harry groaned before starting to walk off but a loud meow stopped him in his tracks and he turned to the black cat and looked apologetically at him. "The Dursley's wont let me keep you." Harry stated. "And I can't stay here all day." He apologised but the cat just stared at him as if saying 'yeah and?' Harry sighed and walked back to the cat picking it up. "I guess annoying the Dursley's does sound fun." Harry laughed and carried the cat out of the park and back towards the house. "You just have to keep quiet." Harry muttered and the cat again meowed before going silent and Harry walked up to the house and tried the door… Unlocked, guess the Dursley's forgot to lock the door. Harry opened the door and quickly went up the stairs and into his room. Closing the door he walked over to his bed and placed the cat down on it. The cat stretched and then curled up in a ball. Harry smiled and walked back out of the door closing it behind him as he went downstairs to prepare breakfast for the Dursleys.

Curled up on the bed she was amused at how easy it was to trick this person into taking her in, now all she had to do was find a way back to the Silver Pinnacle… wherever that was now, she had to report to Neferata… But if she was unable to find a way back then it wouldn't be all that bad after all she could easily change this world and take over.
