~Kingdom of Shattered Mirrors~

~A Kingdom Hearts fanfiction~

~Alternate Universe to Kingdom of Broken Hearts~

"Every world isn't unique. There are copies, like the reflection from a mirror. Identical places, events, people, all quietly existing in their side of the mirror. The two worlds are perfectly parallel.

Yet something always happens that ruins this flawless reflection. One side of the mirror is broken. The mirror shatters.

You, Daxen, have shattered the mirror."

Day One

"Two new members in one day? Man, that's weird."

I ignored the comment coming from the corner of the room as I entered, avoiding eye contact with the strangers around me. Judging from the voice, the speaker I'd overheard was only a few years older than me at most, his words seeming to fall lazily from his mouth. I purposefully faced the opposite direction from him.

The large room was mostly white, with a huge window making up one of the walls. The only furniture was a few couches and small tables, all white, of course.

Whoever designed this place really liked white, I thought as I made my way toward the giant window. Standing in front of it was a man with long blue hair and piercing golden eyes. There was something about him that impressed and intimidated me at the same time. He somehow demanded respect just by standing there and eyeing me.

"Number XVI. You will begin your training immediately. Today you will go with Vexen." He held my gaze as he spoke, his voice deep and serious.

Training? What training? A small part of my mind wondered. I nodded automatically, ignoring the foolish side of me that wanted to argue with this obviously powerful man. I couldn't remember his name, but then again, I barely knew the names of anyone here.

"Stop staring at me. Go wait for Vexen elsewhere."

Again, I nodded in response to the man's order and walked a few feet away. For some reason the world outside the window seemed to be calling to me, begging to be looked at. There wasn't very much to see, however. The view was dominated by a dark sky, speckled with stars. Whatever lay below was hidden by mist.

As I waited for Vexen, whoever that was, I thought about the other people I had met.

Xemnas was first. An image of the tall, gray-haired man appeared in my mind, as vividly as if he were standing right in front of me. He was the one who brought me to this place- or castle, as the others called it. I had joined some kind of Organization.

But why? And what had happened before that? I remember arriving here, but... Why is everything else so hard to remember?

I hadn't thought too hard about my past before that moment, and now confusion flooded my mind.

Who was I?

I knew my name- Daxen. My rank in the Organization was Number Sixteen.

But that was it.

That was all I could remember about myself.

I felt like something was missing. Like I had forgotten something important. I felt…

I felt a hand on my shoulder.

I spun around, dislodging the hand. The owner of said hand turned out to be a tall, thin man with spiky flame-colored hair and mint-green eyes that were oddly flamelike in their own way. I vaguely remembered seeing him when I was introduced to all the other members of the Organization just a short while ago. He was Number Eight, if I remembered correctly. But what was his name...?

I stared blankly at the redhead as I tried to remember.

"Hey," he greeted me, smirking. "So you're the new kid. Number Sixteen."

I nodded, noticing I wasn't intimidated by him like I was with some of the other Organization members.

"I'm Axel, Number Eight. Got it memorized?"

Axel. That was it. I nodded again in response to his question.

"The grump over there who gives out orders is Saïx," Axel informed me with a nod toward the blue-haired man. "The dude with the guitar-"

"Sitar!" The person who had commented about it being weird to have two new members in one day protested. Turned toward the sound of his voice, I found him to be a guy of about average height who was probably around the same age as Axel, maybe a few years younger, with dirty-blond hair and green eyes. He held some sort of strange instrument that he was lazily strumming. That must be the "sitar," I realized.

"Sorry, sitar, whatever," Axel corrected with a roll of his eyes. "Anyways, that's Demyx. Over there is Roxas-" he pointed toward a boy about my height with short, spikey blond hair and large blue eyes standing near Demyx- "and Xigbar." The latter was a older-seeming man with a long black ponytail of hair and a single golden eye. An eyepatch covered where his left eye would have been, while a large scar marred the opposite side of his face. He glanced over as his name was mentioned, but quickly looked away.

"...Where are all the other members?" My voice was quieter than I had intended, and I cleared my throat in the hope that it would sound stronger next time. It was the first time I had spoken that I could remember.

"Probably out on missions," Axel replied with a shrug.

"Missions?"

Axel sighed and ran his hand through his long hair. "You don't even know what the Organization does, do you?"

I shook my head.

"Well, we all have a reason to be here. Don't ask me what your job is, though. I have no idea. Anyway, once you're given a task, you'll go out on missions. Usually they involve battling Heartless- you any good at fighting?"

"...What are Heartless?"

Axel sighed and ran his hair through his hair again. "You have a lot to learn, kid," he finally muttered.

"Indeed he does."

The strange voice coming from the hallway opposite the window startled me, and I turned toward the source. I wasn't too alarmed because Axel didn't even flinch at the sound, so it must be someone he knew.

A tall, thin man entered the room, his gaze locked on to me as he neared the window. He seemed to be the elder of everyone else I had seen so far, yet his eyes glimmered like a child's. His long hair was a sort of whitish-brown in color... or maybe it was a very pale shade of gold? I wasn't very good at naming colors.

"Oh, it's you," Axel boredly greeted the stranger. "Daxen, this is Vexen. He's supposed to teach you the basics of missions and stuff today."

"...Right." My voice was sounding stronger the more I used it.

There was a moment of slightly awkward silence as Vexen eyed me, while I calmly returned his gaze.

"Right, let's get going," the older man said finally, holding out his right arm to the side. A swirling mass of darkness appeared, like a doorway. "This is a Dark Corridor," Vexen explained. "The Organization uses them to travel between worlds."

I blinked. "Between worlds?"

"It's like Roxas all over again," I heard Axel mutter as he stood nearby, watching.

"I see you have much to learn. Do not worry, I will teach you what you need to know," Vexen told me. "Follow me."

He stepped into the swirling shadows and I followed, not really knowing what to expect.

The inside of the "Dark Corridor," as my mentor had called it, was very- well, dark. It appeared to be made of living shadows, shifting around silently.

"The black cloaks we wear allows us to travel freely through these corridors without problems," Vexen explained. "The passages here lead to nearly every world."

I nodded although I was still confused. I had the impression that if I stayed quiet and waited, all my questions would be answered.

"For your first training session, we will be in Twilight Town."

An image of a quiet little town coated in the gentle hues of a setting sun appeared in my mind, and I immediately liked the place before I even saw it for the first time. Once I saw it in person, I liked it even more. It was much bigger than I'd imagined, a huge, mostly open space

Once I saw it in person, I liked it even more. It was much bigger than I'd imagined, a big, mostly-open space filled with buildings and shops. Some of the buildings were so tall I could barely see where they ended. Vexen informed me that this wasn't even the whole town, just a section of it known as the Tram Common.

"Unfortunately, this place, like nearly all the worlds, is crawling with Heartless. It'll be your job to help defeat them, usually with one of the Keybearers. Can't let all those hearts go to waste," my mentor commented as we walked around the Common.

I paused, confused. "Heartless?" I remembered that Axel had mentioned those earlier. But what were they? "Who are the Keybearers? And... what are hearts? Why shouldn't we waste them?" There was so much I wanted to know. I hoped Vexen wouldn't be angry with me for not knowing these things already.

Vexen stopped walking as well, turning toward me. "I see there are many things you do not yet know. I'll start by explaining Heartless. They are creatures of the dark that lack hearts, so they attempt to steal those of others. There are many different types of these creatures, from small and weak to large and incredibly strong. It will be your job to destroy them."

"All of them?" I wondered.

"Of course not!" my mentor snapped "There are far too many. You will be given a set amount for each mission."

That made sense. I nodded to show my understanding.

"In response to your other questions, Keybearers are those who can wield a weapon known as a Keyblade. This allows them to collect the released hearts that would otherwise simply fade away into another Heartless. Numbers XIII, XIV, and XV are Keyblade Wielders."

I knew Number XIII was Roxas, and Number XV was the girl named Alexa who had joined the Organization at the same time I had. Who was XIV?

"As to what a heart is..." Vexen resumed walking, and I followed him. "It's what will make us complete."

I was confused again. Did that mean we weren't already complete?

"You and I, along with nearly everyone else in Organization XIII, are what is known as Nobodies. The empty shell left behind when a human with a strong will loses their heart to the darkness. It's very rare that a Nobody is formed, but you in particular are even more special. The chance that you would exist is about one in a million, and only in specific timelines..."

"Wait, wait," I interrupted him, stopping suddenly. "So, not only am I not really whole, but I'm not even supposed to exist?! And what do you mean by timelines?"

Vexen sighed in frustration. "This is going to take even longer than I thought. Maybe I should wait to finish explaining until you've had time to learn on your own."

"No." That single word came out sounding much harsher than I intended, but I didn't apologize. "I want to know now."

"Very well, then," my mentor agreed. "You see, every world isn't unique. There are copies, like the reflection from a mirror. Identical places, events, people, all quietly existing in their side of the mirror. The two worlds are perfectly parallel. Yet something always happens that ruins this flawless reflection. One side of the mirror is broken. The mirror shatters." The look in his eyes was serious as he stared at me intently. "You, Daxen, have shattered the mirror."

"...That didn't really help to clear anything up at all," I muttered. "Now I'm even more confused."

"You will learn more as time goes on," Vexen assured me. "For now, you must focus on your training."

As we resumed walking again, I briefly reflected on all I had been told so far. Every answer I was given only led to more questions.

I guess I did have a lot to learn. But I was ready and willing. I, Daxen, a member of Organization XIII, would find all the answers.

(Authors note - I hope you liked that short story! Feel free to leave me a review and tell me what you think about this story. Thank you for reading! Seriously. You people are amazing. Thank you so much for reading this first chapter.

TheRoseAlchemist17 wrote this first chapter, along with her OC Alexa and her story Kingdom of Broken Hearts. She also made the title.

Daxen and the giant masculine dog in the bikini are my OCs.

By the way, this story is about to get a lot weirder.

Just a warning.

Oh, and there's a lack of bolding or indentations this chapter because of sending issues between me and Rose.

Thanks again Rose!
