Kingdom Hearts: Rhythm in Motion

Prologue

"For centuries, The Order of the X-Blade (AN: the 'X' is pronounced as either "key" or "kye") has stood watch over the worlds of Kingdom Hearts, keeping themselves and their greatest treasure, The X-Blade, a secret from the other worlds. Each member of this secret society carried a Keyblade, a powerful weapon based off of The X-Blade, both to protect themselves and to identify themselves to other members.

For many long years, there was peace and tranquility in the worlds, but, one day, Xehanort, a Master in the Order, came to believe that the elements of Light and Darkness had become unbalanced; there was too much Light, and not enough Darkness. To that end, Xehanort gave himself up to the Darkness within his heart, and set about planning an event that, in his corrupted mind, would restore the balance; a second Keyblade War. As the first war had caused millions across the worlds to die, as well as being the reason why the original world had split into pieces in the first place, The Order tried to stop him. However, Xehanort successfully corrupted the mind of Vanitas, a young Knight in The Order, and made him believe that the 'restoration of the balance between Light and Darkness' would give him the power to protect his younger twin brother, and fellow Knight, Ventus, from any threat.

With Vanitas' aid, Xehanort was able to invade and destroy The Land of Departure, the home world of The Order, and banish nearly all of its members to The Realm of Darkness one by one, including the children.

One of The Order's leaders, Master Eraqus Xanderville, and his three greatest Knights, Terra Blitzer, Aqua Reyes, and Ventus Henderson, (AN; Don't ask) pushed Xehanort back and spirited The X-Blade, the item Xehanort needed to restart the war, away to an unknown location, out of his reach. Enraged by this, Xehanort banished first Terra then Aqua to The realm of Darkness with the others, and Ventus was flung in as well, sent there by his own corrupted brother.

Upon realizing what he had done, Vanitas turned on Xehanort and helped Eraqus defeat him, but the damage was done, and the Master was lost as well. With his plans thwarted, Xehanort cursed Vanitas and retreated, leaving the boy to wallow in his own grief and remorse…"

Mysterious Tower

It was quiet at the Tower, as it always was. In his personal chamber, Master Yen Sid, a tall, elderly sorcerer with a long grey beard and blue robes that touched the floor, sat at his desk, poring over a large tome. The book was written in a language most would find unrecognizable and illustrated with pictures of people swinging large keys over their heads. Yen Sid looked up as a knock sounded on his door. "Come in," he called. His former apprentice, Mickey, a mouse dressed in red, entered the room, carrying a book similar in size to the one Yen Sid was reading.

"They found a new one in the ruins, Master Yen Sid."

"So I see." Yen Sid took the book from Mickey and set it carefully onto a pile of other books. He frowned.

"There are still two volumes from the collection that are missing. I hate asking them to do more salvage work in such a dangerous place, but-"

"-These books carry the history of The order of the X-Blade in their pages. New trainees will find them useful in their learning," Mickey finished. Yen Sid nodded and turned to the large, panoramic window behind his chair. In the distance, the red and orange buildings of Twilight Town, the refuge of those who had survived the destruction of The Land of Departure, glowing dully in the early morning sun. Xehanort had destroyed The Order of the X-Blade twelve years ago, and for ten years Yen Sid and Mickey had struggled with salvaging as much as they could from the ruins of The Land of Departure, and searching for new Keyblade Wielders in the hope of rebuilding The Order.

Finally, a few years ago, they had begun locating new wielders en masse, The Order was quickly rebuilt, and it had been growing at a faster rate as time went on. Of course, it was comprised primarily of children, but still… Yen Sid turned back to Mickey.

"Go to Twilight Town and give The New Order my request to find those missing volumes. Also-"

Yen Sid reached into one of his sleeves and pulled out a small roll of paper, which he handed to Mickey.

"-Deliver this to them as well. I'm sure it will be of interest to them." Mickey saluted, tucked the paper into a pocket, and left, closing the door behind him. Yen Sid returned to the window. Xehanort's power was growing, and the awful rumors of what he was doing with his power only made the situation worse. Still, if anyone had a chance of stopping Xehanort once and for all, those two boys did…

Twilight Town

Mickey hurried along the path leading away from the Tower. Twilight Town had grown a great deal in recent years, and he genuinely hoped he wouldn't lose his way down there. It never ceased to amaze the mouse just how far The New Order had come in such a short time. They were all young and far less experienced than nearly everyone in The Order had been. What they lacked in experience, however, they made up for in youth, vigor, and fierce determination.

Mickey quickened his pace as the perpetual sun grew brighter. They'd be getting up soon, and he wanted to be there before the "work day" started, as once it did, he'd be there for hours before he'd get the chance to speak to them.

Mickey dropped down into Twilight Town's Central Station Square as a shortcut. Now, did he go right or left? The last time he had done this; he had gotten lost, and spent an hour being chased by a bunch of inquisitive kids! Okay, he was pretty sure he was supposed to turn left at this point. Then, a right at the next turn, and past two residential areas. Next, a quick run through a vacant park to a quiet street where no one was up yet. Mickey proceeded to the end of the street to the last building on the right.

It was a double building; a store in front with a wide, three-story house behind. The house had been painted a neutral beige color, with a dark red plated roof, just like so many other buildings in this town. The windows on the house were clean with white curtains drawn over them. There was no door to the house from the street; the only way in from the front was to enter the store and proceed to the back of it. Unlike the house, which was ordinary, the store was something else entirely. It was red in color, with an orange roof, long windows, and a green and blue door with a long window in the direct middle of it.

The inside of the store was dark and a sign hanging from the inside of the door read, "Sorry. We're closed." Good. He had made it in time. With a satisfied nod, Mickey tilted his head back to look at the large, multicolored sign that announced the name of the place, "Rhythm in Motion".
