A/N: I really like Caius, and know that in the book world, that he was actually in his forties when turned. So that is what I tried to keep, was him actually being in his forties, and Marcus, staying in his twenties when turned. Although, this fiction doesn't really explain, much about when the 'Royals' were turned. But that is the state of mind I am sticking with for this story...

My True Mate, My True Love

Chapter One

Caius, sat on his brothers left, as the tourist entered the throne room. He was still angry about not being able to kill the wolves, when they all went to meet the Cullen's, about three years ago. When learning that the child, had actually been part human, and not the kind of immortal child, which was first thought. He had always liked children, and upon rare occasions, would walk near the clock tower, where children played in the fountain. He kept hidden in the shadows, not wanting to expose himself.

"Hermione, don't do that again!" A woman ran towards the fountain, where a young woman with wild curly hair, had been sitting reading. The woman tsked, as she grabbed the girl by the arm, "Must you always have your face in a book? We're on a family vocation, and would greatly enjoy your full attention."

"Sorry mother," The girl apologized, her eyes swept to where the vampire was in shadow, and quickly stood up leading her mother away, "I think we should get back to the 'Inn', so that we can get sleep, you wanted to take that tour, and we should probably rest."

Caius eyes widened, when hearing about the tour, that was only an excuse to feed the vampires. He knew he couldn't allow for her to become there prey. There was something about her, that made him want to protect her from all harm. His wife knew, that they had not been true mates, was why he talked Aro, into allowing her to leave. She never really felt the need to stay, no matter how strong Chelsea's power, tried to keep the feeling in his wife.

He stiffened, when he felt a pointy thing, at the back of his neck belonging to the familiar scent. "Your stick can not hurt me, a stake through the heart-"

"Won't kill you, I am well aware of that, vampire," A familiar voice finished.

He turned in a blink of an eye, to see the same girl, from the fountain with the stick in her hand, "I could break your stick in two, with just a flick of my finger, you are aware of that, right?"

"And I you, with just a couple words," She countered, not taking her eyes off of him, as they stayed in the shadow.

"Awe, you're a witch," He smiled, once he realized what she was, as he lowered her wand hand to her side, "Then you know about the treaty, if any member of the magical world, were to commit crime of a any magic being-"

"The violator, would be sent to Azkaban for the rest of there lives, or be given the kiss of death," She rolled her eyes, as if he was a small child, sharing already known secrets, "Yes, I know that law, since I am the one who helped, with writing it when I interned at the Ministry."

His eyes widened, not expecting the young girl, to know of the slightly new law. "So you worked with Amelia Fraudric," he stated, rather then asked.

"That would be her department, wouldn't it?" She was getting annoyed, "I-"

"Herm-" A male voice started calling, only to pause at finding the young girl, talking to a young man. The man reached out his hand, as he wrapped an arm around his daughter, "My apologies, thought my daughter was sneaking away, to read something. I'm Oliver Granger, how do you do?"

"Dad, we were-" The young witch started, quickly doing a heat charm, as the vampires hand gripped her fathers, (all she needed was for her dad to realize what the man was.)

Caius looked at the sky, noticing it was now dark, before back at the young woman, "It is I who stopped her sir, was interested in taking her to dinner, and getting to-" He honestly didn't know what possessed him to say that.

Oliver smiled at his daughter, and kissed her forehead, "Suppose one meal without my daughter, won't hurt anyone," he kissed his daughters head once again, before walking away, "Don't be late, we have that tour in the morning."

The vampire turned his attention back to the brunette, as he extended his arm, "He's a trusting man, isn't he?"

"To much so," She mumbled, walking towards the fountain, and taking a seat.

"You don't seem afraid of me anymore," He noticed, sitting beside her.

"You would had done something by now, if you really wanted to," She still had her wand in hand, as she turned to him, "So why are you out, aren't you afraid of being seen?"

"Not afraid of anything, just don't want to be exposed, because that would be dangerous to my coven," He answered honestly, taking both of them by surprise, "What kind of example would I be, if I were to spread the word of our kind, after years of telling others not to do so."

"So what brought you out today?" She asked curiously, noticing how handsome he really was, which was due to being immortal.

"Children," He answered, then quickly reworded his answer, at the murderous look she sent him, "I meant to watch the children, I enjoy watching there innocents, not having any true idea of all the darkness of the world. Only children have that innocence, which we as vampires no long behold, from all the blood."

"Did you have children, before you were turned?" She asked curiously, as he leaned closer, without realizing.

"I honestly can't remember, I was turned 1240 B.C," He looked at a scar on her forearm, that seemed to read actual letters, "What is 'Mudblood'?"

Her eyes widened, as she looked at the spot, when she had placed a charm to hide her scar. "You could see it?"

"Barely, I had to look hard, to make it out," He continued to study her, noticing a few other scars, that was on her right hand, "You have to remind yourself, not to tell lies? Couldn't you had just written it on a piece of paper, without harming yourself?"

She stood up, and walked back under the clock tower, as she kept her back to him, "The first scar was made with a cursed blade, by the most evil witch anyone could ever imagine, and the one on my hand was caused by a blood quill. It writes whatever is on the paper, onto you skin, and it was an old professor, who thought she knew everything. I hate both woman." She wiped at the tears, that were sliding down her cheeks.

He involuntary let out a growl, at the thought of someone causing the woman harm, as he came up behind her, placing a hand on her shoulder, "I apologize for the question, how about we find a place to eat?"

She noticed his hand had still been warm, from when she cast the warm spell, when he went to shake her fathers hand, "I forgot to remove the spell," she waved her wand, causing his hand to be cold, "Sorry about getting upset, just prefer not to remember some things." She looked at her own watch, and started to walk away, "I am sorry, didn't realize the time, I have to get to bed. It was nice meeting you, Sir."

"The name is, Caius, it was a pleasure to meet you, Hermione," He smirked at her surprised expression, "Heard your mom say your name."

"Oh," She realized his eyes had been brown, instead of there prior red, from the other charm she used, "Forgot to change your eyes back, unless you prefer the brown," she waved her wand, causing his eyes to change back, "It was so nice to meet you, Caius, maybe I will see you again after the tour."

"You can't go on the tour tomorrow," He warned, taking her hand in his, "I can show you more places, then what the tour provides, and it wont cost a thing."

"I will ask my parents, thank you, Caius," She went to kiss his cheek goodnight, but caught his cold lips in one of the best kisses, which she had ever experienced.

He tightened his grip around her waist, as he pressed her against the wall, deepening the kiss. He couldn't recall the last time he kissed someone like this, and was glad he didn't need to breath, unfortunately she did need air. He pressed his forehead to hers, as he stared into her caramel eyes, "I'm not going to apologize, since I had been waiting for the chance, but I am afraid I must return."

"You still haven't feed me dinner," She reminded, as she started walking away, towards her the 'Inn', "I have room service, so you can buy me dinner, when we get to my room."

"I can't simply stroll into the 'Inn'," He pointed to his eyes, as he followed close behind, "So I will-"

She leaned back in, and kissed him again, right before they were both pulled by the navel, landing in the middle of her room, "Sorry about that."

He glared at her, as he felt the need to vomit, even though he knew he couldn't, "What did you-" He stopped, as he noticed they were in a room, with a large bed, and sofa by the window, "So this is what the rooms look like."

"Why am I drawn to you?" She asked, leaning against the bed, after waving her wand around the room, casting silencing charms, "I mean your a human drinking vampire, and one of the 'Royals' at that, yet for the last hour I thought about nothing but you, and I, shagging."

"I don't want to drain your blood, but I actually feel like I want to be with you, get to know all of you," He had laid her onto the bed, as he spoke, "I think-"

"You can't hurt me," She assured, cupping his cheeks in her palms, as she leaned up to kiss him, "Stronger then I look, Caius."

Without another word, he leaned back in, and deepened the kiss.

Hermione awoke a few hours later, and turned to where her vampire had been, frowning when she didn't feel him, "Must have-"

"Imagined me," Caius asked, smirking as he got back on the bed, "We broke the head board I am afraid, I'll give you the money to pay for the damage," he removed the sheet from her, so he could see how much damage he had done to her, frowning at all the finger bruise marks, where he held her tightly to the bed, "I am sorry for getting to-"

She waved her wand, causing the headboard to repair itself, then climbed out of bed with the sheet covering her, "Last night was the best night, that I ever experienced, so don't you dare apologize." She peeked out the window, noticing it was still a little dark, "Let me apperate you to the clock tower, after I throw on my clothes."

"You could just sleep, you were very busy last night," He leaned in and kissed her, as he carried her to the bed, and tucked her back in, "Don't go on the tour alright, that's just a way for us to feed, and I don't want to hurt you."

"Was wondering why the tour took place underground," She smiled as he placed a kiss to her temple, before he hurried out of the building, "Good night, Caius."

Two Weeks Later

Caius watched, as his witch looked around his tower, and frowned, "Perhaps you should rest, you're looking pale." He took her hand, and lead her to the sofa, where there was a throw pillow, "What did you eat?"

"It was some meat dish, which didn't upset my stomach the first time, but now the smell gets to me," She could barely keep her eyes open, as she felt Caius's long cool finger stroke her hair, "Do you have-"

He quickly grabbed a wash basin, before she finished her sentence, and held her hair back as she got sick again, "So your parents don't care, you decided to stay a little longer?"

"That was the plan, even before I met you, because I needed to get away for a little while. They didn't buy me a return ticket, just a one way, since I could just go to the Ministry of Italy, and floo home anytime. I live in wizarding London, so they're not concern. They got there family vocation, and I get some me time, before returning home." She got to her feet, and groaned, not know if there was actual plumbing, "Where can I go to the restroom?"

"We do have working plumbing, Hermione, for bathing purposes," Caius pointed to a door, across from his room, "Why don't you stay here, instead of wasting money on a room at the 'Inn'."

"I like the comfort of a bed, not that your couch isn't comfortable, but not for eight our sleep cycle," Hermione answered, going into the bathroom, and closing the door behind her.

"If I had a bed, would you stay here?" Caius asked, watching the doorway, when she hurried counting off random numbers, as she paced the floor. "I'm just late, that's all it is, right?"

"You're late for what?" The vampire asked, grabbing her by the hand, and pulling her onto his lap, "Calm down, alright?" He started to stroke her hair, "What's the matter?"

"I was suppose to start my period a week ago," The young woman answered, going to where the mirror was located, and pushed up her shirt. Noticing the slightest bump, "No." Everything went black, as the room began to swirled.

Caius caught the witch, before her head hit the stone floor, and carried her back to the couch, "How could this have happened. He couldn't help who his true mate was, rather she was human or not, but he should had waited till she turned. Of course he loved the way of her warm body, against his stone like skin, and the noises she made."

Marcus, had even told Caius, during one of the few time he actually spoke, that he knew that Athenodora, was not his true mate. That there was no connection, between the two, but only friendship. When the younger vampire met, Hermione, he said he felt there connection, and it was one of a true mate. "Don't allow her to get away, even though it's against the guidelines, because he wouldn't feel another with the same connection." He was right though.

Aro, was fascinated with the witch, which went on to telling her the story, how he recovered Jane, and Alec, from being burned alive when the village found out they were a witch, and wizard. He even was allowed to hold her hand, and saw the 'war' witch she had fought the previous year, while only in school. She told him that was all she allowed him to see, that there was so much more to her, and that it was none of his business.

Caius, was kneeling beside where she laid, and placed his hand on her stomach, 'She's going to have a child, his child.'

There was a light tapping on the door, before the door opened, where Aro, stood in the doorway. His brother stared at the sleeping witch, and noticed his brothers hand, "Caius, tourist are about to arrive, you should come to the throne room."

Caius, didn't even move an inch, as his eyes stared down at her stomach, "She's pregnant, Aro. I could feel the child in her."

The darker haired vampire clapped softly, as not to wake the young woman, as he looked at the blonde, "They will be like, Renesmee."

The blonde glared at the other man, standing to his own feet, blocking the now excited brother, "Aro, this child will not be, a part of our coven. She would not allow that, since it will be our child, I am sure she would want the child to make there own decision."

"The child will be a Prince, or Princess, to Vultori. We should call Carlisle, so he could make sure the pregnancy, and the young witch stay in proper health," Aro was out the door, before the blonde had a chance to protest.

Three years ago, he had been against allowing the young Renesmee to live, but was now extremely relieved that they didn't kill her. Today it would have been him, in the place of the Cullen's three years ago, and he couldn't bare the thought of hurting either his mate, or child. He was scanning through his journals, which literally filled his whole room, when he came upon the one he had been writing in for the last year, He gently pulled the book from the shelf, and went over to where he had a desk, which was probably as old as the twins. He dipped his quil, and began to write the days events, about everything.

'...I would kill, whoever laid a threatening hand, on my mate, and our child. Rather it be Vampire, Witch, Wizard, or anyone that dared. I never thought I would father a child, and now that I learned I have, no need to get a second opinion, because I had felt them with my own hand. Perhaps Carlisle, when he arrives, might be able to explain how they cared for the young Belle, while she had been pregnant. I am willing to apologize to him, if it meet that my mate was to be looked after, the way that I would like.

I never thought I would be the one, who would fall head of heels, for a mortal. Though she is no normal mortal, she is a witch, my like the twins here. Aro, he is already reffering to the child, as a Prince, or a Princess, of the Vultori Coven.

This child will not be forced, to live the same kind of life, as the rest of us do as vampires. Nor would I ask my mate to live this life style, if she did not wish to either, and will be willing to follow her, wherever she wished to move. I would not allow, Chelsea, to make my mate, or child, have any need to stay. It is her free will that I have grown to love, and hope our child would inherit when they arrive.

I have visualized more than once, having a children, and what they might look like. Never thinking it possible, since I am immortal. Than I met her, my Hermione, who has given me this special gift. She trusts me, in a way that I do not deserve, but am grateful of just the same. Her name will be my last dieing words, if someone were to harm her, because they would have to come through me to get to my family. I- '

"Caius," Hermione woke up to see the blonde at his desk, and walked up behind him, smiling as he grasped her hand, as it rested on his shoulder, "What are you working on?"

"I am filling in my journal," He turned when he was finished, and pulled the young witch between his legs, as he leaned his head against her stomach, "Are you feeling alright?"

She ran her fingers through his hair, and smiled as he placed a kiss to her naval, after lifting her shirt, "You're taking this better than I did."

"I would had fainted, if my body were able," He admitted, now meeting her chocolate eyes, with his blood red ones, "You are my mate, I known that from the moment I saw you, reading at the fountain. Marcus senses our connection as well, and knows we truly belong to one another."

"I should get back to the 'Inn', and pack my-" She was interrupted by a knock on the door, as Jane, entered the room, sending a glare towards her.

"Aro, and Marcus, wish for you to come to the throne room, the tourist are right outside the door," She nodded her head at the witch, before walking out of the room.

"She doesn't like me," Hermione walked over to the mirror, and sighed at what was happening, "I think she likes you."

"She's only mad, because Aro, and Marcus, won't allow her in the throne room, when you're in there," Caius walked up behind her, and kissed her head, as his fingers linked with hers at her sides. "At my request of course."

"Why not let her in the throne room, it's more her home than mine, she should feel free to come as she wishes," Hermione looked at her watch, and went to where her bag was by the door, "Actually I am going to the 'Inn', I love you," With that she disappeared with a pop.

He reluctantly went down to the throne room, and sat in his throne waiting for night, so he could go check on his mate. He feed without paying attention, thinking about the second time he took her, it had been in a field while taking her on a personal night tour of Vultori, now that was a night to remember. Images of a baby played cross his mind, causing him to smirk.

"Carlisle, he will be here in a couple of days, we will set his room for him, and his mate." Aro was grinning, as he looked at his blonde brother, "Perhaps I will have Catalina order a bed, that way the young mother will have a place to rest, instead of staying away from you."

Just then the mortal came in, ignoring the blood being cleaned, as she approached the usual angry blonde. She waited to be acknowledged, as she kept her eyes to the ground, as she had been instructed a short time after being hired.

"What is it you want, Catalina?" Caius growled, not used to talking to her, not really having real need to.

"Your mate called to say, she will meet you under the clock tower, when the sun goes down," She hadn't looked up once, as she waited for a response.

"Thank you, Catalina, you are dismiss," Caius leaned forward in his chair, and looked at the woman, "Please order a bed, and some bedding for it, preferably I would like the bedding in, burgundy, make it the quickest shipment possible. Might want to order pillows, how ever many you might think would be comfortable, no matter the cost. I want Hermione, to feel like this is her home, why don't you order the whole Emily Dickerson Collection, first edition if you could find them , that's her favorite author, and-"

"That would be it, Catalina, we will have the young lady make a list, if she needs anything else," Aro interrupted, smiling at the woman, "You may go home, when you're finished."

"I will be quick about it," Catalina nodded her head, before hurrying out of the throne room, and back to her desk.

Caius smirked, as he watched his mate, listening to her talk softly.

She was laying on the edge of the fountain, one hand laying in the water, and the other on top of her stomach, "Never thought I would be pregnant, after all the torture I been through, even the doctors said you were a one out of a hundred chance. Yet here you are, growing inside of me, and I couldn't be more happy."

He let out a growl, when hearing about the torture, even though he already heard about her past. He walked slowly to where she was, and stared down as she had her eyes closed, knowing she already knew he was there, "If that Belletrix wasn't dead already, I would personally make her suffer, without regret."

"You'd have to stand in line," Hermione smiled, as she stared into the vampires eyes, as she splashed water at him with her other hand.

Caius quickly lifted her up, and carried her over to the clock tower, right in front of the entrance of the Vultori, "You splashed me, don't think anyone has ever done so before," he pressed his lips against hers, then pressed his forehead to hers, as he held her close to him. "We are having company, he knows about this kind of pregnancies, because one of the member of his coven fell in love with a 'Mortal', and they conceived a child, and she died. She turned after giving birth." He cupped her cheek in his hand, as he leaned in to kiss her, "I can't lose you, Hermione, I really couldn't cope."

She smiled as she rested her head against his chest, and closed her eyes, "I am keeping this child, Caius. After as many times I been under the crucio curse, I was told that the chances of me getting pregnant, was only a one percent chance," she had tears that was soaking the vampires chest, as she cried.

"I won't let anyone harm you, and wouldn't dream of making you abort this child," He placed a hand on her stomach, noticing it was slightly bigger, "It's growing. Did you eat anything today?"

"I had two steaks, extra rare," She smiled as he took her hand, as they started walking around, "Which is funny, saying as how normally I don't eat meat, but this week that's the only thing that sounded good. Did you eat, when I left?"

"Yes, I did," He answered, pulling his hood over his head, so no one could see his red eyes. "Are you willing to turn, if you had no other choice, when the child arrives?"

"Of course I am willing, if it meant being with my child," She answered, biting her lower lip, "I sent a message to my best friends, letting them know what's happening, they are probably going to be here tomorrow." She glanced into his shadowed face, not able to read his expression, "There was no way, they wouldn't have come otherwise."

"So these are the friends, who helped win the war, against Voldemorte?" He had slid his arm, around the witches waist, as he lead her to the field, where they made love the second time.

"Yes Harry Potter, Draco, and Ron, probably would be coming with them, if he'd been alive too," Hermione's eyes started watering, when thinking about her friend, and how Nagina, had bit him, right before Neville, cut off the snakes head. He had been distracting the Snake, from going towards her, and saved her life. She had thought she was in love with Ron, but sense meeting Caius, now knew what being in love really was like.

"Draco, he's the one that killed his father, as the man was about to curse you?" The vampire asked, trying out the idea, of actually meeting them, "I will have Aro, set up the guest room for your friends, we should probably order two beds."

"They could just transfigure something into a bed," The witch grinned, as she imagined her vampires expression.

"I had Catalina, order a bed for you, it should be here sometime this week. I think I will try to buy a bed from the hotel, for your-"

"They could transfigure something into a bed, no need to buy more furniture," She waved her wand, before sliding the vampires hood down, and was met with brown eyes staring back at her, "You know you just had to ask, and I could had charmed your eyes brown, so you could walk around without that hood. Could have charmed your skin, so you'd walk around during the day, just don't tell, Aro."

"I am still getting use to your kind of magic, and why didn't you transfigure one of my things, into a bed to rest. Instead you went back to the 'Inn'." He pulled her onto his lap, as he sat on the grass, making sure she was comfortable between his legs. "You don't trust, Aro?"

"I don't trust anyone, who is able to invade my thoughts," She looked up at the toenail shaped moon, and leaned against the blondes chest. "I just needed some time alone, so I could process everything, it had nothing to do with you."

"Well, I feel safer knowing you are near, but if you want to wait for the bed that will be fine," The vampire cupped her cheek, as he leaned in and kissed her, "I have waited many lifetimes, to finally find this kind of love."

"I thought that I would never love again, until I met you," The witch whispered, as she closed her eyes, after placing a heat charm around them.

To be continued...
