Sharing a Kingdom

Ch.3-Invisible Strings

The royal couple were at their new home, sharing their evening breakfast. Mathias and Leon awoke an hour ago to the sun setting in a glorious mesh of orange, pink, and purple. After getting dressed properly, the couple went to their new private dining room. It was a grand room with walls painted a pale grey and the top outlined with painted black vines, looking very realistic as they grew from the ceiling towards the floor. Blackwood furniture littered the room here or there. Darken silver were in the multiple display cases and long silk black curtains covered the four gigantic windows. A great diamond chandelier was in the center of the ceiling right over the blackwood dining table. They owned a mansion now instead of a castle. The blond considered it a downgrade. They got comfortable and began their meal.

"Could you pass the tea love?" Leon asked Mathias. The tactician handed over the white china teapot. Leon poured himself some English Breakfast and stirred the blood butter in the small bowl next to his plate. He smeared some on his pastry and began nibbling on his croissant.

Some time past in silence.

"What's the matter?" Mathias asked, not even bothering to look up from the newspaper in his hand. Modern German had some words he did not know. He could gather their meaning from context clues, but he made a note to restudy it later on in the night. He knew his lover would tell him.

"There's so much to take care of." Leon started, moving on to fresh fruit. Vampires of their kind did not need human food. In fact, most of it made them sick; however, small things like bread, fruit, deserts, and drinks did not make their stomach quake. "The house, our finances, and now the school…"

"And?" Mathias asked, turning the page of the newspaper absentmindedly. There were a few sales going on at the furniture stores. He already knew what was troubling the blond.

"And, you already know." Leon rolled his eyes. "I want him. The timing seems terribly misplaced."

Mathias just turned another page. "And I have agreed either way, so what's the problem?"

There were very few things the couple could hide from each other due to time and their mating bond. Sometimes though, Leon gets a feeling he misses something every once and a blue moon. "So, shouldn't you consider this a little more?" The former Knight hissed.

Giving a comical sigh, Mathias said, "What is there to consider, darling? I met him the same time as you. He was angry and rude but he's gorgeous and obviously being mistreated by both vampire and hunter sides." He placed the newspaper down to work on the strawberry sweet tart a servant goblin just brought. "I'm not dismissing him, Leon. I can feel your desire."

Leon deflated. "But what about your desire?" It all seemed unfair to his mate.

Mathias smirked around the pastry bite and swallowed. "I've known you too long dear. My desire is your desire. He's an abandoned kitten that has caught your eye for the moment." Continuing to eat, he thought about his next words. "And while it could develop into to something more, I do not feel threaten. My beast is interested in him as well."

Leon scrutinized his husband in silence and Mathias continued to eat. After a while he said, "Sometimes you baffle me after all this time."

"I know." Mathias smiled, sipping his glass of blood.

The Pureblood Prince was staring out the window during class. The subject was history and he knew everything. Not many things could actually make him study. He absently felt his inner circle's boredom as well. Many of the noble vampires in this class were at least a hundred years older than the human professor speaking to them.

Kaname's eyes lighten up at the sight of his sister Yuuki walking by and he gave a small smile. Although she had recently turned back into a pureblooded vampire, she insisted on performing prefect duties until more hunters could be sent. Much of Vampire Society thought it improper but they could do nothing, nor would Kaname allow them to.

The pureblood needed to hold a meeting after class. It had been five days since the new patrons came to visit and it worried him in the back of his mind. He had no doubt he could kill one of them if need be but two? Not to mention the other would be enraged that their mate had died or gotten injured. The Blackbloods' power could easily overpower him if given the chance. Everything was so disconcerting.

Out the corner of his eye, he saw Takuma look at him worriedly. Whoops, Kaname let unease slip into his aura. He looked at the other to let him know he was fine and continued to look out the window. Yuki was already gone.

~*Sharing a Kingdom*~

"Ugh." Zero groaned in his sleep. The hunter felt unbearably hot despite the temperature. He was in his dorm room with the window wide open, blowing the cool winter air in.

Wait.

Blearily, the hunter opens his eyes a crack. Since when did he leave the window open? Zero's breath hitched as he felt a warm caress up his side. But there was no one there as Zero turned his head slowly side to side. Why was he so hot anyway? By all rights he should be a frozen huntersicle.

Another wave of scorching heat went through the hunter, making his stomach twist into a knot. What was it he felt? Hunger. No. It felt more like—

Lust.

Zero groaned as blood rushed south, but he felt too weak to move. Somewhere in the hunter's clouded mind his instincts knew this wasn't normal. "Ah…" Zero moaned quietly as the warm touch came back again, caressing his hips.

You should wake up now.

Zero jerked wide-awake from his strange dream, shoving away his blue comforter. The hunter sat up quickly, looking around his room. It was daylight with the sun shining brightly through his thin white curtains. His windows were closed and nothing was out of the ordinary.

However, Zero could still feel the hot breath that whispered into his ear and the remnant of heat through his body. What the hell was that?

~*Sharing a Kingdom*~

Leon gasped unnecessarily as he came out of his trance and his glowing blue eyes faded back to normality.

The small room was only lit by the five tall black candles, standing on the points of the blood drawn pentagram. Leon was in the middle of it with legs folded in a lotus. He was drawing his dark magic in tendrils back into himself.

He laughed mirthfully. The hunter's aura was so desperate and lost. He did not think Zero even knew how truly lonely he was. Or maybe, Leon thought, he's so depressed everything has just merged into a giant numbness. However, there was some light left in the hunter. Leon guesses its what keeping the hunter sane.

But the reaction Zero had to him was instant. The hunter's soul was enthralled with the sensuality and affection that Leon had offered. His body reacted so deliciously that the former Knight's desire spiked even more.

He will speak with Mathias to pay a visit to the school soon. He has to plan this carefully.

~*Sharing a Kingdom*~

"What is it Kaname-sama?" Takuma asks as he sat down in front of his leader. The inner circle vampires were gathered in Kaname's study, sitting in various seats or standing.

Said pureblood was pacing back and forth in front of the fire place. The muted aura he felt just a few minutes ago was unnerving. It was dark and powerful and somewhat familiar. He stopped to look at his coven. "It's about the new patrons. I wanted to speak with you all after classes."

"Ah," Shiki said in recognition. "The new patrons that just bought the school?"

"Yes." Kaname nodded to his cousin. "They are powerful Black Bloods. The Chairman and I do not know where they stand between Vampire Council and Hunter Association."

"Do they mean harm to the co-existence?" Takuma asked.

Kaname let out a small sigh. "I'm afraid we do not know that either."

"Then what do you want us to do, Kaname-sama?" Aidou asked from the left-side of Shiki.

"I want you to keep an eye out when they are here." Kaname said contemplating. "I already have Seiren gathering information on the patrons. Since they are cordial as of now, we can only prepare for another unseen enemy. If it comes to a fight, do not engage one alone. These two are aristocrats like us in their kind's society. From their powerful auras, we can at least expect powers on par with a pureblood."

"Powers like a pureblood?" Kain asked worriedly.

"Yes." Kaname nodded. "They are much more powerful than what anyone expected I believe. Not even the Vampire Council nor the Hunter Association expected them to be this powerful."

"Should we tell Yuuki-sama?" Ruka piped up.

"I will speak with Yuuki alone." Kaname replied. "She already knows of their existence just not our plan of action."

"And her protection?" Takuma asked, looking Kaname in the eyes. There was silent stare down for a moment.

"I will handle it." Kaname nodded and dismissed them. "You all may retire for the day."

The group nodded, standing up and leaving one by one except Takuma.

Once the door closed, the blond stood up. "You're going to use Zero again, aren't you?" Takuma asked and came closer to his brother-like friend.

"I have no choice." Kaname sighed. "Yuki still loves and trust him. I have requested his help on this matter too."

Takuma was surprised. "And he agreed?"

"With some coercing yes." Kaname walked over to his desk and sat in his leather chair. "The Chairman also convinced him. He still has love for Yuki as well."

"And how do you feel about all this?" Takuma already knew the answer.

"Don't play games with me Takuma." Kaname smirked as he knocked over his white knight chess piece. "I absolutely loath it."

~*Sharing a Kingdom*~

A few days went by with Zero having the same sort of dream. Each time he was about to wake up a voice and ghostly touches would plague his mind along with an unbearable heat.

However, last night's dream was different. It was hotter than the previous ones, making him actually tear at his clothes unconsciously. The mysterious dark voice whispering to him had gotten lewder. It told him of the things it would to do his body, how it would make him scream and moan. And each time it said:

Come be mine.

With a possessive tone more devious than the devil himself. To be honest, Zero was scared out his fucking mind. He's had enough! He was about to meet the Chairman and talk about these strange dreams. The hunter has always suffered sleep deprivation but these past few days have been strangely peaceful as well. Zero actually feels great besides the feeling of being violated hanging around in his mind.

The hunter knocked on the Chairman's door loudly. There was a lot of shuffling from the other side before Zero heard: "Come in!"

As Zero stepped inside, his adoptive father finished arranging the papers on his desk. Closing the door, Zero walked and plopped down into a seat across from the Chairman's desk. Cross' face was completely surprised.

Cross started, "Zero, what—?"

"Someone's been messing with my dreams." Zero said bluntly. "I want to know if there is a charm to make it stop."

"Your dreams?" the Chairman said alarmed. "When on earth did this happen?"

"This past week." Zero scrubbed his hair with a pale hand. "I didn't realize it at first. So, can you make it stop?"

"They have to be a powerful hunter or vampire to perform dream magic." The Chairman sat down roughly in his office chair. "What exactly have they been doing in your dreams?"

Zero steeled his face so he wouldn't blush. "Well…to be frank they've been trying to seduce me to come to them."

Blond eyebrows raised to the Chairman's hairline. "Se-seduce…?"

Zero rolled his eyes. "Yes. I think whispering dirty things in a person's ear counts as seducing." He specifically chose to leave out the ghostly touches, knowing his adoptive father would flip more shit.

The Chairman's eyes began to water cartoonishly and he whined. "NOOOO! Not my dear son. They can't take away your innocence. I won't let them!"

"BE SERIOUS!" Zero screamed. "Is there a charm or not?"

Cross coughed. "Ahem, well, there is a simple charm we could try. Since they are not trying to cause "harm," we could block them with a water protection spell." The Chairman took a sheet of paper and drew the magic circle and words to say. "Just use this in the bathtub or lake before the next time you sleep. It has to be a large body of water. Hold the paper above the water and have a medium to lock the water with the magic in it that you can wear. Like your earrings. It will warn you of the intruding aura and block them out after you realize their presence in your dream."

"Good." Zero hissed. "I'd rather not sweat bullets every night." Before the hunter could leave his idiot adoptive-father, who was whining again about his innocence being taken, Kaname's aura registered in his senses. "What now?"

There was a knock on the door before the Chairman said, "Come in, Kaname-kun."

The pureblood stepped in, wearing a black button up shirt and white slacks. He was quite casual considering the circumstances bringing him there. "I have information on the patrons."

"Here we go." Zero grimaced.
