Chapter one

"Kick me out of my fucking bed, like I have a place to go!" A violent voice screamed through the silence of the cemetery. The clear night permitted the full moon to shine down upon the raven-haired girl with light pale skin. Her eyes flared of torment as the dark green tore through the light mist. Her steps heavy with extra weight of a large duffle bag packed with her clothes and possessions. With the height of 5'4", she swiftly moved along the emerald sparkling grass with her black trench coat clipping at her heels.

Quickly she reached her destination and before knocking on the door of a old gray stone crypt belonging to one of her very few lifelines that she trusted left, she wiped away tears that stained her eyes and cheeks from the walk over. With a deep breath she knocked her fist against the thick cold wooden door, and heard from within a voice. "It's open." She exhaled her breath and let herself in, her hair covered a majority of her face until she shut the door and placed her bag on the floor. She pulled the hair out of her face and stepped slowly and slightly ashamed towards the tempered attractive blonde male vampire that sat on the couch before her.

Spike grew curious quickly as to why this raven haired girl only known to him as Rei could suddenly appear on his doorstep with a bag of all of her possessions and with such a distraught expression. "Rei, what's going on, luv?" was all he was able to muster up at the time. He moved over on the couch and motioned for the girl that looked about 19, to come and sit with him. At first she just raised her eyes to meet his before closing her eyes and turned her head away. She wasn't usually one to depend and feel comfort from others, but now wasn't the time to let her pride and usual attitude get in the way; he was all she could trust now. She looked back to Spike and silently walked over and sat next to him, finding herself leaning on him as he put an arm around her.

"Xander kicked me out..." Her voice was quiet now, unlike her cursive screaming outside, it sounded submissive. She continued, "he said that he can't have me around anymore especially if he's going to get himself an apartment away from his parents. I can't believe them...first Buff, then Willow and Tara, Giles even...Spike...I came here because Buffy is my only tie to anyone in my blood...I don't know how they could just, toss me out like that. Its not like I can do this by myself...." She trailed off into thought, 'The council will only want to drag me back, probably for termination...' She shook her head and leaned forward resting her head in her hands.

Spike listened, he always did, Rei was an interesting girl that way, and she never spoke of her past, only of how she was going to go on. He had heard some interesting things come from her mouth, which made him wonder; wonder if she was older then she looked. Each time he didn't ask, trying do dismiss it as a curious mind, but lately he couldn't. "Where you going to go now?" He tried to keep conversation going, hoping that his questions could be answered soon.

She looked back up to him, "I...I was hoping I could stay here...just until I find my own place...so I don't get in your way all the time." So many thoughts ran through her mind at that moment, most of which she tossed into the back of her mind and locked away to try and forget.

"Don't mind, as long as the Slayer doesn't show up all the bloodytime." He smirked jokingly. Quickly he glanced over to her bag, it seemed to only hold her clothes and the necessities. "No bedding...s'aite, we can get that later, it'll be day-break in a few hours." He watched as her eyes lit up and literally leapt on him in embrace, if one was to pay close attention they would notice it was a sudden turn on for him, but he pressed it out of his mind for the time being.

"Spike, I don't know how to thank you," she paused and gave a thoughtful grin, "actually...yes, I do know how to thank you. Although I do believe Buffy would be baffled for weeks, and be at my throat in anger, hehe yea I think that would be quite entertaining." She looked into Spike suddenly lust filled eyes, 'I do believe I know what's on HIS mind.' She snickered and crawled off of him scampering away over to her bag, and returning with it in hand. "William, a warning for your benefit, it wouldn't be a good idea to lust after me." She could just imagine the broken expression he held as she dug through her bag, pulling out two black boxes.

Spike sat up, calming himself down and grew confused about her comment, "I shall lust upon who I wish to lust after luv." He replied as his curious eyes watched her open each of the boxes, one seemed to be filled with a needle and numerous vials of some violet liquid, he knew she had carried this box with her on several occasions, the other box, held an ancient artifact with a scroll. "What's this now?" He asked as she removed the scroll and sat it beside her, and then removed the artifact, which seemed to be some sort of ancient Incan sacrificial box.

"In simplest terms, its a gift box...I received this too many years ago to remember. I do remember however that I got it from the goddess Shiori, goddess of order. This has the ability to take back, any injury, infection, parasite, or foreign object placed in the body, for example, the chip." She quickly explained as she set it up and laid out the scroll on the floor.

His eyes flew wide open, "You mean I can be rid of this bloody chip, for good?" She nodded, Spike grinned maliciously. "That's bloody well brillient." He exclaimed to himself, "If you can honestly get this bloody chip out of my head, you can live here forever if you want." Seating himself on the floor across from her and in front of the box.

"That sounds great, and we're ready to go here...but I have to do something first" Her voice faded quickly as she sat herself up onto the couch and grabbed the other box. He watched her as she sat down and started pulling an elastic out of the box and wrapped it around her upper arm and prepared a syringe. Quickly she injected the violet fluid into her veins and she tossed the needle back into the box as she bit down hard onto the thick silver chain around her neck and shut her eyes tightly, fists clenched. He didn't notice it right away but her eyes had changed from their emerald green shade to a light orange, the roots of her hair had slowly taken a change as well, giving it white streaks, but they quickly subsided as the substance made its way through her , Spike took the box and put the vile and syringe back into their places, throwing away the needle tip and put the box back into her duffle bag. When she seemed to come to he questioned her, "What's all this about? Some sort of new street drug, or perhaps something that you snagged from Commando boy..." His temper began to rise.

Rei let go of the breath she was holding and dropped the silver chain from her teeth, it was warped and mangled. She opened her eyes and they slowly faded back from their orange to green again, her hair re-darkened to black as well. "Of course not! Fuck...its a mix of different herbs...monkshood, rose, lavender, and nightshade...a few others." She took off the elastic tied around her arm, tossing it back into her bag. Then set herself back onto the floor, "It keeps it dormant and weak..." She saw his leering face and quickly picked up the scroll, "I'll tell you the rest after I get that chip removed from your brain."

Spike gave her an odd scowling look, 'Monkshood, that's a poison, nightshade, that stuffs deadly..what's she up to.' "Alright Rei, your the one with the scroll, do your thing." Rei nodded, seeming back to herself she began reading off the scroll, a smile grew as she finish the incantation and held Spike's hands over the box and told him to close his eyes, which he did.

Within a second it was over, the bright flash, the chip was removed from Spike's brain and hovered in a light over top of the box. Spike watched the chip with a grateful look on his face, but didn't notice how Rei continued to chant yet again, but a different incantation then what was on the scroll. Soon there was another flash and then the light vanished, the box and scroll vanished as well, returning themselves back to the hands of the goddess that gave it out. Rei was curled over on her side in extreme pain and clutching her head. "What did you do!" Spike demanded, picking her up and putting her onto the couch, "Where's the chip, where's the artifact?"

Once the sudden pain had subsided after a minute she took a breath and opened her eyes looking at the face of a concerned vampire, "I used the three gifts the box contained.....so it vanished."

"The chip Rei, what happened to the chip?"

She tapped the side of her head with a light smile, "In there...the last spell was to take the chip into my own brain. Its the only way I can prevent another massacre from happening without taking the injections every day."

"What massacre, Rei your making no sense!" Spike spoke flustered.

"Spike...do you remember when you, Drusilla, and Angelus were in China and Angelus came back after a huge slaughter, coated in blood, and with that small dead girl in his arms?"

Spike was shocked, how could Rei know of any of his ventures, especially so soon after he was sired. "Yes....how do you know about this...watcher's journals?"

"No Spike...Angelus never started that bloodbath, he arrived in the center of the city after it was over....I killed all those people...Spike, I killed that little girl." Although she had never spoke of this to anyone, or even tried to, her expression remained calm.

His eyeballs nearly jumped from their sockets, "YOU did that? But that would mean you're at least 130 years old!"

"149 actually...even if I look merely 19...because I was 17 when I caused my first massacre. When I first found out I was a form of slayer at the time. A watcher had hunted me down on one of the occasions that I had become ravenously bloodthirsty, knocked me out, and tied me up. He told me everything, of how that my real mother had twins, and that how I was one of them, my sister was a slayer, which meant I myself had some extreme strengths as well, but mine were distorted and twisted. They called me The dark Slayer, because I wouldn't protect my own kind from demons, I would rampantly destroy mortals. The council held me for 2 years, and for those years they restrained me and tested different mixtures on me. One day they gave me a mixture that had doubled my speed and power, enabling me to escape, in doing so I tore apart everyone in the building. I was out in the streets again, at the time people were scared and stayed inside because of the vampires, but as you know, they couldn't enter a mortals home. But I could...I would leave cities burning with bodies horribly mangled and dangling from clock towers and stables. Before soon after I escaped, I met a witch, whom I didn't kill. She reminded me a lot of my mother that took care of me most of my life, she taught me a few spells and I earned her trust, But as my nature goes, I betrayed her, I killed her in the middle of a ceremony. Shiori, goddess of order, was infuriated with me, she gave me that Incan box, and said that I had three gifts from it, one for myself, the second had to be for someone else, and the third I could have for myself. Naturally I took the gift of an immortal life, but I couldn't just let anyone have the second gift...I never found anyone to give the second gift to. So I set out, with my immortality I would never age, and I would be able to satisfy my bloodthirsty nature, the next place I attacked was that place in china. The child I handed to Angelus wasn't killed by my hand, she had been beaten by her father. I had attacked her father first, which triggered my lust, before I could grasp myself again most of the city was in ruins like the rest, but the child that I had attempted to protect, was already dead. I gave her to Angelus because he was the only one I could see standing and willing to approach me, and that I couldn't bear to stare at that child's face any longer, to see how I had failed her. Once Angelus left I was caught again by the council, they seemed to had come up with the perfect mixture to bring back my lust less sanity. Once I was stable they sent me back out into the world, with my drug in hand, I set out to find my mother, and sister. Only to find that in my fury I had killed them too. So I followed the slayers through generations, from place to place, only returning to the council to gain more of the mixture, it was about 5 years before they showed me what was in it and how to make it myself, before they began to trust me again..." Rei sighed and trailed off, looking at the surprised face of the blonde.

Spike took a minute to let it all sink in before asking about the chip, "So why did you take the chip...what will it help with all this?"

"The chip wouldn't let you kill or harm mortals, right? So if it was placed in my brain, then I wouldn't be able to kill mortals anymore either, some of these plants for my injections take a while to grow and find."

"I guess that would solve your problem then love. I'd never have thought you to be from my time" He smirked. "So basically you're like a vampire except for the lack of fangs, sun sensitivity, and death."

Rei smiled faintly, "I guess so." She noticed a stream of light peering in through broken glass, "It's morning...unless you DO want to die, or become grouchy...you should sleep." She giggled lightly.

He stood up and held his hand out to her, "Sleep with me pet?" She gave him an odd look, he shook his head and corrected himself, "I've got no extra blankets except on the bed in the bottom level...it'll be warmer then the couch...no funny business, I promise." Rei snickered to herself and took his hand, and her bag, and followed him to the lower level to his bedroom.

Spike pulled off his black shirt and tossed it on the end of the bed and sat on the bed still in his jeans. Rei rummaged through her bag and pulled out a pair of silver shorts and random black tank top and quickly changed with her back to Spike, whom watched with amusement. "What, shy dressing in front of someone luv?" he joked.

Rei turned to him as she pulled on her shirt, and stuck out her tongue to him, "No, just don't want you lusting after what you said you wont touch." She smiled and then tackled him on the bed. Spike was surprised at her behavior, but was even more surprised when she didn't move from her spot on top of him, and leaned down kissing him lightly. She rolled off and onto her own side and snuggled up to him. "Thanks for listening to me.."

Rei was the first out of the two to wake up, she saw Spike was still in a peaceful dead slumber. Slowly she climbed off of the bed and brought her bag upstairs with her, flicking on the TV and getting changed into a regular pair of black pants and a black and red snoopy tank. Glancing through her bag she saw the box of liquid that had been keeping herself dormant, she smiled. "I don't think I have much more need for this." she said in a glee filled manner and proceeded to pour the contents out one of the windows covered in heavy drapes. She looked at the time that the TV said it was and smiled to herself as she turned it off and grabbed her long jacket and headed towards the door of the crypt. "It's still light, by the time the sunset is over Spike should be awake," as she finishes her sentence she closes the crypt door behind her. Turning around she swiftly makes it to one of the angelic statues that stand in the graveyard, she found herself a seat on the alter that laid in front of the angel. Crossing her legs in front of her she found herself lost in the swirls of red and violet created from the sun and surrounding clouds. Soon the sun had set and she lingered a few minutes more observing the violet clouds darken to midnight blue as the minutes past. She began to move when she felt two strong cool hands restrain her in place from behind, after a failed attempt to pull out of the grasp she tried to see who it was. The figure that was clearly male behind her brought himself up beside her ear and smirked, "You can never be innocent, the bloodlust is two great to be tossed away in time...you'll come to understand that Rei." His voice sounded very familiar but she couldn't remember in her decade and a half of life. As she struggled to remember her thoughts dissipated when she felt his bite deep into her major artery, but it wasn't the bite that she felt pain from, no, the bite was a soothing reminder to what she once was. The real pain came once the strange vampires fangs were removed from her throat, it was the strong electric shock that he inflicted with a tazer. enough power jolted through her body to overload the chip in her brain that was once Spikes. She curled over in pain holding her head as the chip shorted out sending smaller shocks through her brain. When the pain finally subsided she found herself being lifted up from the ground. The hands belonged to Spike who seemed to hear her painful cries.

With a concerned look on his face he looked back and forth in her eyes and questioned her, "What happened, pet?"

Rei blinked a few times to clear her blurred vision and then quickly turned her head looking around for the other vampire who had attacked her, "Where'd he go!" she demanded, while spike simply gave her an odd look meaning 'who'. "The other vampire...h-he said I'd never be innocent and that my bloodlust was to great to just let go...knew my name Spike! Then...then he bit me, and it was like he tried to finish me off with a tazer, but it wasn't enough to kill...just send the chip all haywire..." As she spoke all this out she struggled to understand it all. He looked to the side of her neck where she was bitten, blood seeped still quite quickly from the punctures. "Do you know who it was?" She shook her head, "No. but he sounded familiar...like I knew him before...and he had this aura around him...it felt so powerful, evil, but powerful..." Spike seemed to have a vague idea of who it was, but wanted to check into it before he began making assumptions.

It was that moment that Rei's expression dropped to horror, "The chip...SPIKE! He short circuited the chip!" She went silent and pulled herself to her feet, wishing that just half an hour ago she didn't pour out all of her injection fluid. She figured it would be less then a day for her dark lust took control of her and went on a murderous rampage.

With this new information about the chip no longer functional, Spike's guesses were confirmed, "Angelus is back in town Bit...and I take it he's got some plans for you."

Spike took it upon himself to go to buffy and the scoobies and inform them of the glorious return of the beloved Angelus, yet neglected to tell them that he had plans to do with Rei. Meanwhile Rei stayed back at the crypt, she had refused to go with Spike to the Magic Box. She was trying to come up with a way to control her darker side once again, she had no access to the various plants that were needed for her injections. So far the only option she had to prevent her uncontrollable bloodlust, was to shed her own blood, to end her own life, or to try. Nearly an hour went by and the girl could slowly feel her control leaving her and no other solutions had appeared in her mind. Spike still wasn't back yet either, nor did she expect him back for a while, suspecting he went out to feed now chip-free, or went to find his sire Angelus.

Rei dug through her bag until she found her only weapon she had with her, a dagger decorated in Egyptian runes and designs. It was quite beautiful, except for the blade, sharp enough to split hairs, yet had a red stain upon it. After all these hundred or so years she still kept the blade she had caused massacres with, never washed it from the blood of the innocence. She smiled ever so faintly as she sat herself down onto the couch in front of the TV, one of Spikes shows was on Passions or something. She never paid much attention to what was on the TV, only really ever had it on as a voice in the background, to lessen the deepness of the silence within the crypt. The crypt that she planned on taking her immortal life in. As she lowered the blade onto her skin with fair pressure she bit down into her lip, feeling the skin of her wrist instantly split making way for the blade as it sunk down deeper. The blood wept from the wound as the metal was lifted up, only to be brought down again and making a long slice from wrist to mid-forearm, along the major veins in her arm. She stopped and dropped the dagger onto the cushion next to her as she gazed upon the steadily flowing blood oozing itself from the depths of her left forearm and onto her lap. Her attention was so well kept she didn't notice the door of the crypt opening and a figure entering.

She was brought out of her daze as she felt and saw two icy hands grasp her wounded arm and bringing it up to the intruder's mouth. Her eyes were torn off of the wound and up to the intruders face, her mouth gaped open slightly as she instantly recognized that it was the same vampire that she handed the dead girl to years ago, and the same one that attacked her earlier. She watched him lap at her wound, licking up all the blood trailing over her arm. Her vision was beginning to become hazy as a result of the major blood loss. The last thing she saw before fading into the darkness was the icy hands tending to the deep wound to mend the gash.

Angelus glanced up momentarily as Rei's eyes rolled up into their sockets and she shut her eyes falling unconscious, he simply smiled and muttered to himself as he sewed up the wound, cleaned up the blood and wrapped her arm in gauze. "We can't have you ending the game before the fun gets underway now can we..."

Flashback

"And another thing, why do you wear those goddamned gloves, its the middle of summer!" Her father screamed at her, nearly finished his lecture about killing off his livestock by tearing it into shreds and leaving them to bleed themselves dry and waste away in the sun.

"Well what the bloody hell do you expect me to do! I'm obviously a sin within your eyes father, how else can I hide myself from the world, lock myself away in a box? No! I'll go mental. Sure I'm one fucked up kid, dad. But at least give me the goddamned decency to hide my imperfections the best I can from society." She blurted out of her simple 14-year-old mouth.

A sudden crack was heard as he punched her in the side of the jaw, dislocating it. "You will NEVER talk to me like that again child! I am your father, and I will induce discipline upon you before you get completely out of control. Now clean this fucking mess up before your mother gets back from town." With that he turned and left inside the small one level farmhouse.

The girl tore off into the barn hiding herself up the ladder behind the bails of hay, she quickly dug out a black velvet bag from the hay and wiped away her burning tears as she opened the bag pulling out an Egyptian dagger. She remembered getting it from another child on the street, she had traded one of her best dresses for the item, faintly she could remember that the child she had traded it with was a girl as well, and resembled herself quite closely. Pulling her gloves from her hands she traced her fingers over numerous purple and white scars all in different stages of healing. Scars that symbolized her confusion, her hatred of herself, and above all hatred towards her father. Holding back another sob deep in the pits of her chest she took the dagger and firmly pressed the blade upon the tanned skin, making the deep gash overlap 3 of the other scars. Normally she didn't cut across her wrist where the veins were, only at the sides where the veins were absent, yet this time she felt the feelings buried within her were too strong to be let out by a simply mended gash, she needed the pain, needed to see that same pain leave her. Dropping the dagger she began to get woozy as she reached for her cloth that she wrapped up her wounds in, but found that she hadn't enough energy to even wrap the fabric around her wrist and simply watched it fall onto the hay.

Luckily for her another pair of curious eyes were watching her, those of a female wearing rich glamorous clothing. She seemed to wonder why such a pretty little girl would be hurting so much to go to the lengths of bleeding herself. Pulling herself out of thought when she noticed that the girl had lost so much of her precious life fluids, that she couldn't even managed to cover and compress the gash she had inflicted. Ignoring her deeper instincts to lap away at the sweet odor of the fluids, she moved herself into sight in front of the girl and quickly began mending the wound for her, pulling out a needle and thread she normally used to mend small imperfections within her clothing whenever it got ripped or torn, she threaded and stitched up the deep flowing gash and wrapped it securely with the fabric. Only then allowing herself to clean away the drained blood from the girls arm with her tongue, once the girl was cleaned up nice and proper, the blonde haired woman placed a kiss upon the young girls forehead and smiled. "Sleep well child, for when the time comes, my own childe will come to take care of your tender mind and body, and train your soul."

End flashback

When Spike finally came home it was close to morning, the first thing he noticed was the heavy sent of blood which sent him into initial worry. The couch was covered in it, all of it was the girl's, "Oh bloody hell....I leave her for one night and look what happens!" He ran though the crypt searching for the girl, anxiety growing quickly, but was able to calm himself when he found her all unconscious and wrapped up on the bed n the lower level. She was pale and had shallow breathing, her eyes fluttered here and there in a dreaming state. He neared her and sat upon the edge of the bed, slowly and carefully taking her injured arm and unwrapping the bandage from it to see to extent of the damage. Seeing that it was very deep indeed he ran his finger feather lightly along the line of stitching in the skin holding the wound together. He knew that if Rei was in such an unconscious state that she was in now, she wouldn't have been able to stitch up the wound and bandage it up AND get herself down onto the bed from the couch upstairs. Someone must have assisted her, doing it for her, but who, and why.

Ok first chapter is up and edited. Read and review people, any suggestions are loved and welcomed, as well as flames, they add into the chaos of my mind.
