"Vampire" - Talking

'Vampire' - Thinking

Updated - 9/29/2018

Chapter 1:

"Death." called out a soft and lilting voice that echoed in the moon drenched meadow.

The person to the voice was a young looking woman about her late teens early twenties and around 5'4 to 5'5 tall. She had long black hair that reached to her mid-thigh and long bangs that framed her face and stopped at her chin. The hair was so dark and silky looking that people once mistook it to moving shadows in candle light.

Her skin was almost as pale as snow and if one were to touch it, it would be just as cold. It didn't make her look sickly though, but ethereal instead. As if she didn't belong on the mortal plane. She had a heart shaped face with bow shaped pale pink lips, a button nose, high cheek bones and below well shaped black eyebrows were two almond shaped emerald green eyes that glowed in the dark.

"Mistress." A voice as brittle as dry leaves rustling in the wind, answered.

Appearing behind the woman was a silhouette made of shadows. When the figure solidified, it was of a tall being covered from head to toe in a dark as night cloak that moved with liquid grace even when the wind wasn't blowing. No matter what angle one tried to look from, one couldn't look pass the cloak to see what the Being looked like underneath. Not only that, she knew from experience if one tried to touch the Being, their hand would go right through Them as if They're not really there even if They do look solid.

"Death." The woman repeated on a sad sigh this time. She looked at the Being over her shoulder with sad and haunted green eyes. "How long must I stay in this dead world?"

For beyond the meadow they were in, there was nothing but barren lands and dried up oceans, rivers and lakes. There was no life what so ever on the earth anymore. There hasn't been any for over 500 years and she couldn't take it anymore. The silence and just plain out nothingness that she has to put up with day in and day out had twisted her in such a way that she would have conversations with herself for hours on end until she realized what she was doing and then stop. One time, Death had to intervene because she ended up getting in a fight with herself and was tearing her flesh off her bones in her rage at herself.

The meadow she had stayed in for years only had green grass and beautiful flowers because of the magic she pours into the earth to bring color into the gray and dead place around her. The moment she stops the magic, is the moment everything withers and dies. It didn't matter how hard she tried to bring life back to this world, it never works.

"What do you mean, Mistress?" He deflected back to her.

"You know what I mean. Ever since the mundanes destroyed the earth in their mad desire to rid it of anything they thought were unnatural with their atomic bombs, I have been waiting for the earth to recover and life be brought back to the world. Except, it's been over 500 years and still there is no life but me. So, how much longer must I stay in this world? When will I be freed from this immortality?" She demanded with rage and desperation in her voice.

Her friends and family were lucky in that they died 50 years before the mundanes found out about the Wizarding World. It was the year 2112 when chaos ruled the world and everybody was fighting for their lives. It was only a matter of time before it happened what with their technological advancement growing every year. It just happened that one of their satellite prototypes, which were stronger than any they had ever built before, caught sight of Diagon Ally.

Curious about the new and undiscovered place, the mundanes sent spy planes to scope out the area. When the planes got too close to the place and mysteriously died on them, they waited for some of the people to come out so that they could capture them and interrogate them (read: torture the information out of them). Once they learned about the magic these people were able to wield, it all went downhill from there.

The mundanes became desperate to control that power for themselves. When they couldn't, they decided that they would rather destroy the magical people and creatures in their jealousy and hatred. Of course, there were some mundanes that tried to help the magicals, as best they could, and in returned for their kindness, they were killed alongside the ones they tried to protect.

On the verge of losing the War, witches, wizards, and all the sentient magical creatures: werewolves, vampire, banshees, veela, etc. all banded together to strike back at the people killing their friends and family. It was a complete bloodbath and it became worse when the mundanes brought out the atomic bombs in their anger of almost losing against the unworthy. They didn't realize what they had done until it was too late and everything was dying with no way to save it.

The only one to have survive the death of the Earth, was her and that was only because of the dubious pleasure of being the Mistress of Death. Though she was the Mistress of Death, it didn't mean she didn't suffer. Having her flesh burnt away, her insides turned to liquid and her blood being evaporated whenever she was caught in an atomic bomb – which happened twice – was an experience that she wished she had never gone through. She not just experienced all of that, but she also experienced her body rebuilding itself cell by tiny cell.

It took 12 years after the last bomb she was hit with to overcome the insanity that overtook her when re-experiencing the rebuilding of her body. When she came to, all she could remember of that time was her killing off the rest of the mundanes. She couldn't remember if she had slept, eaten, or interacted with anybody during those 12 years.

It would also be the first time she met Death. Not any of the times she had died, but it was when she was the only one left alive on Earth, that He showed up. He explained that she was his Mistress and as such could never die. She had screamed and raged at this Being that wouldn't allow her to pass on to be with her loved ones. It took two years before she talked to him again and the reason for that was that she was lonely and desperate for championship.

Unfortunately, Death wasn't able to stay with her 24/7. She doesn't know where he goes since he never told her and she hasn't asked. All she knows is that she always felt something missing when he's gone and feels whole when he comes back.

"There is a way for you to leave this world." Death said instead of answering her question about her immortality.

Scowling and looking hopeful at the same time she asked, "I can leave this place? I could see my loved ones again? Why haven't you told me this before?" She growled the last question through gritted teeth. "FOR OVER 500 YEARS I HAVE BEEN ALONE AND YOU ARE NOW TELLING ME I COULD HAVE LEFT THIS WORLD?" She was screaming in his face with tears of sorrow and anguish running down her face.

"Yes, you can leave this place. No, you couldn't have left until now and it will not be to the place where your loved ones are." Death answered undisturbed at being screamed at by his Mistress. He gotten use to it over the years so now He doesn't even blink at being screamed at by her.

She took a deep breath to help calm her raging emotions, "What do you mean I couldn't leave until now? Why won't you allow me to be with my loved ones?"

"Even though you are my Mistress, you haven't gone through the complete process of obtaining the full power of that position so can't traverse to the other worlds and dimensions as I can. So, we had to wait until the planets align to open a door that you can go through to another world."

"What do you mean by a door? And what do you mean I haven't obtaining the full power of the position of being your Mistress?" She asked in confusion.

"Every 500 years, the planets align and when they do, the doors to other worlds and dimensions open. There were rituals that wizards have created to travel to these places before they were lost or destroyed when people began to fear them. As for not having obtained the full power of your position, you have been subconsciously rejecting the power and as such don't have it under your control." He stated simply. "One of the things that will tell you that you have accepted the power is when you become one with the Hallows."

She looked at the Invisibility Cloak around her shoulders to the Resurrection Stone on her right ring finger and then to the Elder Wand in the wand-holder on her left forearm.

"Become one?" She questioned softly in confusion.

"The Hallows will become absorbed into your magical core and then you will have the knowledge you will need to know about your position." With that he said no more on the subject no matter how much she demanded him to.

She pursed her lips in aggravation at not getting any more information. "Fine, be that way. When will this door open?" She spat out.

"In a weeks' time at 3:03am, we only have an 8 minute window for you to go through until you have to wait another 500 years for another door to open." The silent - if you accept the power from the Hallows then she could leave anytime she wanted - was still heard loud and clear but was ignored regardless. She didn't think she could ever fully accept that power since it keeps her from the ones she loves.

She turned away from the Being that won't let her die to look at the bright crescent moon. The only companion - other than the sun - that never truly leaves her.

"Then go and prepare what needs to be prepared. When the time comes, I will be ready to go through this door into another world."

"There will be side-effects to going through the door. Som..."

"I don't care! Go do what needs to be done."

The Being stood in silence for a moment just looking at His lonely Mistress who was just standing in the middle of the meadow looking at the moon as if trying to find answers to the questions running through her head. Bowing His head slightly, He disappeared to do His Mistress bidding.

"Soon I won't be alone anymore." She muttered to herself with such hope and longing that if anybody had heard, their heart would have clenched in sorrow from the emotions that they had heard.

~One week later~

"Is it ready?" She asked the Being that entered her meadow.

"Yes, Mistress, it is."

"What must I do to be able to go through?"

"If you would allow me, I will take us to the ritual site." He answered while offering His left arm for her to grab.

Without any hesitation she grabbed His arm in a tight grip. She was ready for this. This whole past week she felt so restless because she knew change was right in her grasp and feared that something would happen to prevent her from going through with the plan. She had ended up in another argument with herself from the stress of the wait that Death had to come and break it up. She was just lucky that she didn't ruin any preparation for the ritual with her mental break.

As the shadows gathered around them and then crawled up their bodies to cover them, she couldn't help her heart speeding up in excitement. For this was it, the moment that everything - for better or worse - will change. When the shadows receded they were in a different location. She looked around and wondered where they were.

"Where are we." she asked out loud when she couldn't define their location.

"This place used to be known as Stonehenge before it was destroyed by the humans." He answered simply.

"Oh."

She glanced around to see what was left of the place, all she could see were broken pieces of stone sticking out of the ground in a large circle with a very beautiful and very complicated ritual circle in the middle of it. Before she could get a closer look at the ritual her attention was captured by Death when He started to drag her to the middle of the circle.

"We don't have much more time before the planets align." He explained expressionlessly when she gave Him a dirty look for dragging her around.

Signing, she nodded in understanding. When they got to the middle of the circle, she started to feel nervous about what was about to happen. She knew there will be side-effects from going through even if she didn't allow Him to tell her any of them; she still heard that there would be. She was afraid that if she allowed Him to tell her about possible side-effects, she would end up losing the nerve of going through to a different world. So, she interrupted Him before He could say any more, it was as well because of her impatient need for companionship.

"Stay here." He commanded before He turned around and left the circle.

"You're not going with me?" She asked with wide-eye horror.

"No. I don't need to go through this door to get to the world you are going to. I can travel through anytime I want." He stated neutrally.

Even though there was no emotion in his tone, her eye twitched when she got the feeling that He was smug about that fact. She also got the feeling that He was hinting at the unsaid; she too would be able to do such a feat, once she fully accepts the power of being the Mistress of Death. Shaking her head, she decided to ignore the unsaid statement once again.

"It's time to start." He warned before He started to chant in a language she had never heard before. It was both loud and quiet, everywhere and nowhere, soft and rough all at the same time and it brought a chill down her spine.

When the chant started, the circle started to glow as bright as the moon - which was full that night. When the chant started to go faster, the glow turned blood red. At the end of the chant, the glow turn pitch black, by that time she had become unconscious and spread out on the ground. She had no awareness of the ground opening up under her, absorbing her body into it.

When Death stopped His chant, He was the only one left in the clearing. Both His Mistress and the ritual circle were gone.

"I will see you soon my Mistress." He stated into the emptiness before He too, was gone from the clearing.

~On the other side of the door~

A strange sounding hum pierced the silence of the night as a young looking man made his way home after going grocery shopping. The man was around 6'0 with long ash-blond hair pulled into a long ponytail, his soft hazel eyes were covered by thin oval shaped glasses. Though he was a very handsome, mid-thirties looking man, people gave him a wide berth because of the odd cloths he wore and how goofy he would act most of the time.

However, the off-tune humming stopped when the man got to his doorstep and saw a small bundle lying where he almost put his right foot at. He quickly drew his foot away from the bundle. He put his two grocery bags down to bend over the bundle and started to unwrap it to see what it was.

He flinched back in shock when he saw a beautiful baby girl sleeping in the cloth which he now realized was an adult size black robe. He looked about frantically to see if there was anybody around whom the baby could belong to except he couldn't see anything but the trees that surrounded his home.

When he turned back around to the baby, he couldn't help but pick her up and cradle her against his chest.

"What happened to your parents little one?" His light baritone voice asked softly.

He looked around one more time to see if there was anybody nearby that would clue him in on what was going on. He had never been put in this position before and he didn't know what to do.

'Who would leave a baby on an unknown persons door step? For all they know, I can be some type of sick fuck that likes little girls.' He thought in disgust at the person who abandoned this little girl.

When - once again - he didn't see anybody, he took her inside with him.

"I guess I will keep you until we can find your parents." He hummed. 'Though I have a feeling that wouldn't be a good idea; for if they abandoned you once I have no doubt they would do so again. Next time, you might not be so lucky.'

When he got her situated in a cleared out dresser drawer padded with a pillow and blanket, he ran back out to get the groceries he left on his door step. After he got that sorted, he ran back to the store to get some of the things he needed to take care of a baby. When he got back, he checked on the girl, happy she didn't wake up while he was gone.

'Now, all I can do is get some sleep. Tomorrow and on wards it's going to get a lot more hectic.' He thought with a sad glance at the peacefully sleeping little girl.

Over the next few weeks, he sent out fliers and messages through the police in hopes of finding the little girl's family. They hadn't gotten any takers in that time, so he decided he would just adopt the little girl whom he had fallen in love with over the weeks he took care of her. It didn't help that the moment he saw the gorgeous and sad green eyes, his heart had gone out to her.

"My little Willow, I am going to be the best daddy to you." He promised the little girl in the high chair in the kitchen while the man himself spun around happily cooking some concoction on the stove.

The name, Willow, came to him in a dream the night he found her on his doorstep. He was going to call her Midori - because of her eyes - the next morning but this strange voice kept whispering the name Willow and when he uttered it out loud, the little girl gave a dimpled smile with a giggle that brought a smile to his face. Thinking that she liked that name, he decided to stick with it in the end.

That was how one Willow Dorea Potter-Black, Girl-Who-Lived-To-Be-Immortal became Willow Cross, daughter of the eccentric man known as Kaien Cross.
