PROLOGUE: Calm before the Storm.

A thousand years before Earth's Technology...

(~Lux-Dissidia 012-Final Fantasy~)

Silver Millinum, the kingdom on the Moon which glowed in the night seen within Earth, was a happy and peaceful Kingdom, within the Solar Universe. For many generations, the royal moon family protected this peaceful land by their wisdom, courage and love, and only those with the royal blood could bear the power of the most powerful artifact of the Universe-the Imperium Silver Moon Crystal, and only a Princess who would be crowned as new Queen would become the next wielder of the Crystal.

In the royal throne room of the Palace, the current Queen of the Moon Kingdom, Selene, who wore a beautiful lavender silky long dress, her crimson hair as red as the Earth's rose, eyes blue as the Earth's water, and cresent moon symbol on her forehead, stood paitently as her beloved daughter, Princess Serenity, in a white dress, her purplely silver hair, now seventeen years old, approached her mother, as royal maids and council stood by the sides. Among the guests, was an nineteen year old young man, Prince Grimoire, his long black hair tied up in a tidy ponytail, his crimson but gentle eyes, wearing a dark black and red robes and armor with a sword hilted at his side.

Serenity approaches her mother, who presents her a chained tiara with a cresent moon symbol and places it onto the Princess's forehead.

"Tomorrow is your crowning ceremony...Serenity." Selene told her daughter, for today is her final day of being Queen of the Moon kingdom.

The young Princess nodded, replying, "I understand, mother."

(~End Lux~)


Meanwhile...tweleve years before the true adventure begins...four years before a calamity begins to reawaken...in 1984...

Destiny Islands, a tiny world with islands surrounded by water, while a peaceful place, to a heart seeking freedom, this world was a prison, one of the many worlds within the Multiverse. A man in a dark coat, stared out at the sea, holding something that was covered in a white cloth in his left arm. It's been years since the man had seen this place, for the last time he saw it, it was but a teenaged young man.

But nothing changed in this world. Nothing will change. Destiny Islands will always remain the same. He approached the smaller island that was connected by the wooden bridge, placing the blanket onto the leaned Paopu Tree. It was in the darkest night.

"There, you see?" the man spoke, sounding quite close to his mid eighties. "An empty world, like a prison." he gazed at the thing which was revealed to be a young eleven year old blonde-spiky haired boy who seems to be lifeless, as the older man continued, "I imagine you'll be right at home."

The boy, who was hidden within the white blanket, for his eyes were dull and lifeless, closed as he began to lose consciousness.


Hey, where am I?

(~Destati-KH: BBS~)

"Who's there?" the boy spoke, possibly in a dream. But no, the boy knew, this was no dream. He dived through light, sinking down below, as the blanket that surrounded him melts away into nothing, leaving him only in shorts and shoes, for he was shirtless. Still dulled, but at the same time, aware, he gently rightened himself up and landed gently onto a white platform.

He gazed around, as he heard a voice speak to him.

I'm a brand new heart. Said the voice.

"But this is-why are you in my heart?" The boy asked to the voice, for he knew, he was in his own Station of Awakening.

The light brought me. The voice said, sounding young like a child, yet also wise like the age of the boy. I saw it shining in the distance...and followed it here.

The boy placed a hand to his chest, realising what the voice, the new born heart, was talking about, and agreed, "Yeah. That was my light." but a part of the station was broken, as if cracked and collasped, for the boy continued, "But my heart is fractured. And now...the little I have left is slipping away."

As if the new heart wanted to do something to help the boy survive, it then suggested, Then you should join your heart with mine.

"Huh?" The boy asked.

Suddenly, the light on the platform glowed brighter, and all of the sudden, a new gap filled up the broken part of his heart, restoring it, fixing it, and, somehow, his heart was now connected to the new heart whoever it belonged too. A new born child who, in mind and spirit, was just a baby who possibly would never know their heart's power.

Now our hearts have touched. Nothing else will slip away. The voice continued, And one day... you'll be strong enough to win back the part that already did.

Realising that the new born heart was willing to help the boy survive until his heart was recompleted on his own, the boy nodded, replying, "Right...thanks." (~End Destati~)

It's time to wake up now. All we need to do is... The voice began.

"Open the door." The boy and the voice both said in unison, and in a flash of light, it melted away like petals, transforming into a green platform with the boy's picture on it, except his picture wore a shirt, and was holding a wooden-style like Keyblade in his hand, almost he was asleep.

His station of awakening was recreated.


The man gazed at the seemingly lifeless form of the boy, his hands behind his back. With not much else to do, he turned and began to walk away.

(~The Key of Light-KH: BBS~)

However, he sensed something move behind him, and heard a familiar cling. Pausing in his steps, the man turned around, and his eyes widened in awe.

"A Keyblade?" The man asked, admittedly surprised. How could this be, though? He was certain the boy would not survive.

True, the boy was holding the same Keyblade as seen in his Heart, up in the air as he had turned to gaze at the sky. Then, a beam of light shot out from the Keyblade, and into the sky, for it exploded into particles of light, like blinking stars. The boy's eyes then began to open, as they also briefly sparkled.

The man, witnessing this astonding event, smiled.

This was a birth by sleep. (~End The Key of Light~)


Meanwhile...in a future where time no longer is...

In a bedroom in a far distant future, a young eleven year old boy, with short dark navy hair, with two fringes hanging from each side of his face, blue eyes, wearing a brownish collor shirt, light blue baggy pants, black and white sneakers, was lying in his room. He sat up and sighed, for he couldn't get to sleep.

He gazed out of his window, and, a shooting star catches his attention. But excitement filled up in the boy, for this was no ordinary shooting star. The boy knew what it was.

Laughing happily, he cried out, "He's here!" then leaped off his bed and raced out of his room. That shooting star was a sign of his friend arriving from a world close to Earth, invisible to the human eye. But the boy and a few friends were the only ones thus far who knew about the other world's existance.

The world of Pokemon.


(~Future Masters-KH: BBS~)

The boy raced down the stairs of the building that was once known as the Labratory of Proffessor Oak back in the 20th Century. It was now used as home to those who lived after the calamity that destroyed Time in all of the universe, except for Earth, because of Neo Queen Serenity recovering Earth with the Silver Crystal around eleven years ago now. But Earth still had dark parts where the time's destruction of darkness took hold, so the survivors had to train themselves to fight against the darkness incase the Queen couldn't help them.

The boy made it to the bottom, and sighed, "Grovyle wouldn't meet me from here."

Grovyle, a Pokemon from the world of Pokemon, where it's main source, Temporal Tower, had collasped centuries ago, and was also the boy's best friend, who could come visit Earth every now and then to visit the boy. Today was one of those days.

The boy then raced to reach the area of the village that was originally known as Pallet Town, and found himself into the training area where the house of the Ketchum hold used to be. Seeing the training objects of hanging training rings, teh boy smiled, then shrugged. He pulled out a wooden sword he used as a weapon to fight Pokemon who's hearts are consumed by darkness, but this could only be used to knock them out, for he didn't have the heart to kill them.

"I've got time to spare!" The boy said, then crouched and held his weapon close to him(Note: His fighting style is just like Sora's, in case you're wondering.) and then readied himself to train, like he was about to fight an opponent. He then raced forward and whacked, smacked and down-slashed at the ring which took every hit, which was pretty powerful for a boy of his age.

Sastified, the boy raced to four more and grinned, unable to help himself, "Want a piece of me too, huh?" he taunted like he was speaking to an enemy, and dodge-rolled and single-handedly whacked another ring, which caused the entire thing to spin, and he attacked them with ease, not losing sight of his targets.

Once he was done, he then realised what he was doing, and nearly smacked himself in the head. "Wait a minute! What am I standing here for? Grovyle's waiting!" and with that, he raced towards up the hill that over-viewed the down, and where the sky was more clearer.

The boy puts away his sword and made it to the very top of the valley and towards a cliff where parts of the valley had broken off, having created the cliff and a new valley down below, as the boy was gazing at the sky. More shooting stars appeared, and he smiled as he realised what they were. (~End Future Masters~)

"Wow...a meteor shower!" he said. Not seeing Grovyle yet, the boy decided to lie down and had his hands behind his head, as he gazed at the lights. He then thought to himself, "Wonder why Earth is the only world that still has Meteor showers?" before closing his eyes to think.

Fifteen minutes later, he opened his eyes. He must've fallen asleep after a nap. He sat up to look around, before yawning, then layed down again...only to see a girl's face tower over him.

"Whoa!" He jolted up right in fright, before turning to the girl who had blondish brown hair in small looped-up double-pony tails, blue eyes, wearing a redish-pink long sleeved shirt, with dark blue shorts that was strapped around her shoulders, long white socks that end up to her thighs, shoes that matched her top and was about ten years old. She giggled at the boy's reaction.

"Gimme a break, Lyla!" The boy scolded, as he was sitting on his knees, pouting.

Lyla grinned, then stood up, placing her hands on her hips, shaking her head, like she was his mother or something, "Jason, you silly billy! How did I know you'd be here to watch the meteor shower?" she said.

Jason blushed a little, while quickly protesting, "I-I was just waiting for Grovyle. He said that we'd meet around here and-" only to be cut off when Lyla bumps him on the back of his head, and he grunted, "Ow!"

"You know how he's always late, especially since he comes from the Pokemon World." Lyla pointed out as she leaned forward, with a smile.

Shrugging, and knowing that, as usual, that his friend was fright, Jason smiled in return, "Yeah...I know."

The two young friends then, after Jason stood up, walked over to the edge of the cliff and sat down, their legs dangling from the high ground, gazing at the sky. Jason then asked to his friend, "Say, Lyla. How came Earth is the only world that still has time? Why we still have the sun rising and setting each day?"

Lyla thought about how to answer her friend's question, then began, "Hmm...Well, they say-"

"That Earth is protected by the power of the Silver Crystal." a new deepish voice continued behind them. The two kids turned around, and smiled, as a familiar gecko Pokemon, Grovyle, who, along with other Pokemon in the Pokemon world, are capable of speaking human language, stood there with a smile of his own.

"Grovyle." Jason greeted.

Grovyle nodded at his human friends, and continued, "Yes, and according to research, the Silver Crystal can last forever, as long as it isn't used as much, or that it's wielder is powerful enough to stay alive." as he walked up closer to them while the two turned around, while making sure not to fall backwards before he stopped.

"Wha?" Jason asked, dumbfounded. "I don't get it."

"In other words, the Crystal restored time and light here on Earth, Jason." Grovyle said again, while rolling his eyes at his young friend's gullibleness. Despite Jason being smart for his age, especially when it came to Temporal Tower's collaspe, the boy seemed to be clueless in his own world's history.

Jason stood up and joined his Pokemon friend, asking, "So the Silver Crystal is connected to Temporal Tower?"

"I doubt it, but it's powerful enough to keep this world safe." Grovyle answered.

"Then why couldn't it protect the other worlds?"

"I'm sure we'll figure it out. Besides, you're still young."

Jason pouted at Grovyle's comment and protested childishly, "Hey, I can take of myself and I can fight too, y'know!" which caused Lyla to start giggling before she went into a laughing fit, causing the two of them turn towards the giggling girl, with annoyed looks on their faces.

"Hey, what's so funny?" Grovyle pouted.

Lyla tried to settle down, but still held a huge smile, as she apologuised, "Sorry..." before admitting with a grin, "It's just that you both act like Pokemon and Pokemon Trainer from the past." before turning away and continued her giggles. At first, Jason and Grovyle stared at her as if she was crazy, but then realised what she meant, and soon, the two of them joined her in laughter.


(~Destiny's Union-KH: BBS~)

A little while later, all three of them sat on the edge, gazing at the stars of the sky. Lyla then remembered something and stood up, saying, "Oh yeah! You guys are gonna go start your investigation research tomorrow, right?"

At their nods, Lyla then pulled something from her pockets, holding three items with blue gems implanted in them, and held them up to show her two friends, saying happily, "I made you guys good luck charms."

She then went over to Grovyle and attatched something around his neck. When Lyla leaned away, smiling, Grovyle fingered his new silver chained necklace that suited him perfectly. Hanging from the hang, was the blue gem that looked like it belonged to a star-shaped crystal.

Jason smiled in admiration, until Lyla placed something on his left wrist, as she said, "Here, Jason." and when he looked when she was done, he was a leather-stretched material wristband, which showed another blue gem from the same star-shaped crystal, seen to his eyes on the back of his hand.

"I get one too?" He asked.

Lyla smiled, and placed a silver hair-clip on the left side of her hair, with a third blue gem seen, again, from a star-shaped crystal, as she answered with a smile, "Yep! One for each of us!"

She then turned around, gazed at the sky, and explained, "They say that these blue crystals were once one of a star-shaped crystal called the StarShard, which is said to be one of the many ways to travel to other worlds. Only a Keyblade wielder would be able to use them, some in different colours, though blue was the most common colour of all."

Lyla fingered her gem fondly, as she continued with a smile, "As long as you know how to use them, you'll always find a way to the destination that you want to go." before turning around to face her friends again, and admitted sheepishly, "Technically, I think a powerful Sorcerer created them, but since they were scattered after what happened to Temporal Tower several years ago, I did the best I could with what I had without magic."

Jason rolled his eyes at his friend's techniques in building things, and commented as if it was the saddest thing he'd ever heard of, "Geez, sometimes you're such a girl, Lyla." placing his hands on his hips.

"Hey!" Lyla pouted, feeling a bit insulted, "What do you mean "Sometimes"?"

"And Pokemon wonder why humans can be so complicated." Grovyle shook his head, more to himself. Still, his friends overheard him, and, realising that he was right, both of them shrugged sheepishly.

"Well...I guess you have kinda a point." Jason admitted, rubbing the back of his head, chuckling nervously.

Lyla then added, "Yeah, well, I did learn a little bit of magic and I kinda added a bit to your new good luck charms."

"Really?" Jason eyes went wide in amazement, "Like what?"

The girl smiled as she unpined her clip, and held up skyward, proclaiming, "An unbreakable connection." (~End Destiny's Union~)


In 1988...four years later.

Ventus, a fifteen year old boy in a shirt, shorts and shoes, being the youngest apprentince of Master Eraqus in the land of Departure, was outside of the castle watching the Meteor shower with his friends, Terra, an eighteen year old young man with dark hair, and Aqua, a seventeen year old young woman with blue hair and who had gave her friend and herself star-shaped glass like goodluck charms. Terra's was orange, Ventus's, or Ven for short, was green, and Aqua's was blue to match her favorite colour and her name.

The three of them hanged out after Ven couldn't get any sleep. They trained after that, for Terra and Aqua had their Mark of Mastery Exam tomorrow. Ven gazed up at the sky, until Terra's voice called out to the teen, "Hey, we're gonna head back."

Seeing his friends about to return to the castle, Ven replied, "Yeah, me too!" and catches up to his friends, who, being the only people, other than Eraqus in his life, were more like his older brother and older sister. He loved them as both his best friends and his family, for he didn't even remember his own family, yet, the Meteor Shower tonight reminded him of something, but he couldn't pin point how or why, if he spent his life here.


In the ancient past of one thousand years ago...

Princess Serenity, in her room and on her balcony, gazed up at the sea of stars taht surrounded the Moon and Earth, holding a silver star-shaped locket in her hands, holding it close to her chest.

"Tomorrow, I'll be queen." Serenity said to herself.


1988...

Aqua paused to gaze at the stars, holding her goodluck charm, as she said to herself, "Together...always." before leaving to catch up to her friends.


In the far off future...

As Jason, Grovyle and Lyle were heading back to the village, Lyla paused as she looked at the sky, holding her hair-pin in her hand, saying to herself, "To all of Time." for she wished Jason and Grovyle luck, for the two had made a goal;

A goal to restore Time once more.


"That would've been the last night that things were the same beneath the same stars."
~Serenity, Grovyle, Ventus and Jason.~


Meanwhile, back in 1988, in a mysterious tower world...

Mickey Mouse, the young King of Disney Town for the past four years, being a Keyblade wielder since five years ago, and had gone through many adventures in his world, learning of the past of his long forgotten great uncle, learning about another realm while saving the ghost of his great uncle, becoming a Sorcerer's Apprentince, then a King of his world, travelling back in space and time to Earth's past of 1883 before returning to his present, was now training to balance the light and darkness in his heart.

Though this wasn't necessary, as his master would say, because he believed that Mickey's heart had no trace of darkness what so ever. But Mickey was concerned, especially how his great uncle, or as people would call him now, Retro-Mickey, made a near calamitic mistake and the ink darkness seeped into his heart, and was worried that his own heart was linked to darkness as well, and was afraid of hurting those he loved.

So Mickey had returned to the place where he first fully learned his destiny as a new Keyblade wielder, and told his master his worries and had requested for more training so he can at least control the darkness should it go out of control within his heart. Seeing how Mickey had grown up a little while being careful in how to use his Keyblade, Yen Sid decided that the time has come for his young former Apprentince to train and then show him the quality of a true Keybearer.

The Mark of Mastery Exam.

Right now, Mickey, in another magical realm for his training, and, not really liking this deja vu event of an accident he caused during his early training as an Apprentince, was balancing on a large book that was bigger than him, surfing on rough currents of water, for this was training to balance light and darkness in his heart. Mickey did his best to keep his balance, until a large wave pushed him and the book back.

Clinging onto the book, Mickey was now being twirled around and around in a whirlpool as he screamed. Shutting his eyes tightly, Mickey felt himself being flinged into the air and braced himself to crash into the water. But then, the water and book both disappeared. Opening his eyes, he was back in Yen Sid's study within the tower, hanging in mid-air for a few mere seconds...

Then fell and crashed onto the floor with a bounce and landed on his front. Sighing, the young King stood up, and sheepishly rubbed the back of his head as he stood now in front of his former Master who, like all times he's known the man, held a serious look, seated in his chair.

The powerful sorcerer wore a blue robe with a matching hat which held patterns of stars and a cresent moon, long gray beard and hair. He grunted deeply, for he was about to say something about Mickey's preformance so far, but then, he sensed something amiss, causing him to briefly forget the young king's exam.

"Mickey," Yen Sid began, "I cannot shake the feeling something terrible is about to transpire."

"Hmm?" Mickey blinked, confused as he tilted his head slightly to the side, wondering what had his master worried. The young humanriod mouse had his own worries about his heart, but now that Yen Sid sensed something that was about to happen, Mickey couldn't help but begin to grow concerned himself.

As three stars outside of the tower blinked brighter than others, none of them knew, nor did others in the ancient past, or the future that was yet to come, that the dangerous threat was much closer than they knew, and more catastropic than any of them could ever imagine.

TASHASAUROUS Presents...
A Sailor Moon, Kingdom Hearts and Pokemon Crossover...

SAILOR MOON 0: BIRTH BY SLEEP.


A/N: As you probably know, this story tells the origins of Queen Serenity, and of course, the cast of Kingdom Hearts-Birth By Sleep, as well as the origins of the dark future before it was erased. The Grovyle character in this story is not the same one as in the Pokemon Mystery Dungeon series, per se, but rather, closely connected to him, as is my oc character, Jason, who is connected to the human protagonist, and Lyla, my other oc character, could also be connected. Oh yeah, I made up the name of Queen Serenity's mother as well.

Please review and tell me what you think of this so far, and I'll see you in the next chapter. Don't worry, the reason why this story is called "Sailor Moon 0-Birth By Sleep" will be revealled sooner than you expect.
