Hey guys! FireWolfHeart here in her first ever chapter story! I tend to make some pretty silly mistakes, so if you see any, I'd appreciate it if you would tell me nicely. I've been playing with this idea for a while, but I don't have it completely fleshed out. I have a general idea where I want it to go, though. Anyways, yes, I take suggestions, no, I don't take flames, and yes, I like chocolate chip cookies. Any more questions? I like concrit. I want to become a better writer. Anyways, I'm staying pretty close to the Birth by Sleep plot. THERE ARE SPOILERS FOR 358/2 DAYS! Oh, and Birth by Sleep since it happens along its plotline!
This is teh first installment in a trilogy. The first one, Twilight's Destiny takes place along BbS's plotline and is Ven/OC. The second is Imaginary Light and is a retelling of 358/2 Days. It has Rokushi and slight (okay, I'm actually not sure how often this one will appear in IL) references to TD. And the third on IGNORES DDD and takes place about a year after KH2. It's called Fallen Darkness and it's Vanitas/OCAnyways, enough of my rambling, you wanna read, right?

WAIT, WAIT, WAITWAITWAIT! I love using detail, so some of my suspenseful parts tend to drag out. If you feel that happens please tell me. I really need to work on that. Thank you! Shout out to ShadowofaHeart for.. um... enocouraging me to get this out there.

DISCLAIMER FOR THE ENTIRE STORY BECAUSE I'M TOO FORGETFUL TO REMEMBER IT AGAIN: I... don't... I don't... don't own... Kingdom hearts... There. I said it. Now leave me alone to sulk in my PyroSadistEmo Corner.

My breath escapes in short bursts as I dart around the corner. My eyes roam the alleyway, looking for a hiding spot. Nothing. Despair roots itself in the pit of my stomach as I hear the pounding footsteps of the one pursuing me getting ever so much closer. I whip around another corner. And straight into the dead end. No...

"I really don't understand why you just can't hold still. All we want to do is... ask a few questions. " The cold and chilling voice grates on my nerves, and sends goosbumps sprinting across my arms. A shiver dances down my spine. I just want to be alone. Why can't they see? I hold still, both hands pushing firmly against the cold brick of the wall.

"Leave me alone." The first words I've spoken to them. I feel his golden eyes boring into my back, and fear rises in my stomach. No...

"Sorry, sweetheart. But I'm afraid I can't. I've got my orders. And you're about to get a very rude awakening to the worlds." I turn to face him. His black suit fit the contours of his body, showing off muscles I didn't even know existed. Red highlights veined across his chest, leading down his arms. My gaze travels up towards his face, where a metal casing frames his jaw. Black spiked hair dances in the wind. His golden eyes lock with mine.

I freeze. The fear grows as I take half a step backwards, lightly bumping into the wall behind me. The boy gives a predatory smile and holds out his hand to the side. Orbs of darkness swirl around it and lengthens, creating a very... dangerous looking sword like thingey. It looks somewhat like...

"You recognize this, don't you? It's a Keyblade. Only the strongest of hearts can wield it. Supposedly a little weakling like you can. I'm here to test that," he says, raising the Keyblade above his shoulder and spreading is feet apart. He looks like he's about to... Crap.

He lunges. I scream. Throwing my left hand over my face in instinctual self-defense, a sudden, unexpected-yet-familiar weight startles me. Twisted bubbles of both shimmering light and pulsating darkness fly to my hand, forming a much loved-by-me shape. The Blade begins in silver at the three toothed top, and travels down. About halfway down the neck the silver fades into darkness. A one sides handle with spikes on the outside guards my hand as I draw it back to rest by my side. Shadows flicker over the boy's face as the black tinted silver fire twists around the blade and curls around my fist.

The boy backs up off me and grins a malevolent sneer. His eyes dance in excitement. My heart sinks. He wants to fight me. He's obviously had more fighting expierence than me. I've had... Let's see... None.

"Can I at least know the name of my soon to be murderer?" The question pops out before I can stop it. I instantly flinch, expecting a blow for my sassyness, but instead I look into his golden eyes to see- is that approval?

The boy smirks and gives a half laugh. "Well, you have something in you. That's somewhat promising. Call me Vanitas."

Was that a compliment? I let loose a nervous laugh. "Alright, fine, Vanitas."

I decide to try my luck and swing wildly at Vanitas. He leans back and dodges easily. The weight of the blade brings my arm around until it hits the wall, the three silver teeth clinging to it easily. My left arm awkwardly hugges my chest as I watch the fire lick at the bricks. I tug on the handle, hoping it'll let go as easily as it went in. No such luck.

I glance at Vanitas, desperately hoping it really is a test and he won't murder me. He has a smirk playing at the corner of his lips. I scoff and place both my hands on the handle, giving a firm tug on it. The blade shifts slightly, but nothing drastic. Tiny pieces of rubble drip from the wall as the blade moves. I move my gaze to Vanitas again to see him rubbing at his mouth to hide his oh-so-obvious laughter.

"Go ahead, laugh. Wouldn't be that different from any other point in my life," I snap, snarling at him.

Vanitas sobers. "What?"

I scowl. "You heard me. I'm not repeating anything." He straightens up and stares at me, realization in his eyes. "What?"

Vanitas sighs. "Man, the old man was right. You have to be the Twilight Heart. I can sense your Darkness now..."

I let go of my blade and turn to face him competely. "The Twilight what?"

I scowl as my blade erupts into bubbles, disappearing from he wall as soon as I let go. Figures.

An old rough voice wafts up from behind Vanitas. Said boy steps aside to reveal an old man striding forward. He wears a white shirt with black trousers, boots, and an eerily black overcoat. The underside of his cloakey thingey is a blood, scarlet red. Pristine white gloves cover his hands and the forearms of his coat. His eyes are as golden as Vanitas's, but somehow... colder. Where Vanitas's burned with anticipation and excitement, this man's held nothing but contempt. He frightened me more than Vanitas.

I tune back into what the old man is saying. "... and since your Light is no more powerful than your Darkness, I could teach you to wield your Keyblade to the best of your ability. I could help you control and tame your Darkness. If only you will assist me with one thing in return."

He stops and looks at me expectantly. I narrow my eyes. "What will I be 'assisting' you in?"

The old man grins a very evil grin.

A few months later.

I soon find out that my job is to infiltrate, gain their trust, and shepherd them all towards Master Xehanort, after he's done dividing them. One is to besome the Master's new shell, whatever that is. One is to somehow merge with Vanitas. And the last... I think she's supposed to push them deeper? I'm not quite clear on that. But he Master seems to have everything figured out.

He's amazing! I've learned so much from him! I can actually swing my Keyblade now! He thinks things through so quickly and thoroughly. I don't know how he does it. I'm as impulsive as Vanitas when he comes into contact with chocolate.

Don't. Get. Vanitas. On. A. Sugar high. Ever.

"Need me to go easy on you today?" A voice hisses in my ear. Speak of the devil.

I turn to him and scowl. "No. What makes you think I need it?"

He laughs cruelly and summons Void Gear, back up and easing into his fighting stance. "What makes you think you don't?"

I growl, summon SilverNight to my left hand, and charge. I bend down and give an upwards sweep. Vanitas merely laughs and slices me cleanly across my back. I stumble forwards and somehow twist to face him at the same time.

Not even thirty seconds in and he's already managed to get you. C'mon, Onix. You're better than that!
Shut up, me. You aren't helping.
So? You know the more agitated you are the stronger you get.
But I don't wanna use my darkness!

"You're too impulsive! Slow down, and watch my movements. Let your opponent make the first move," Vanitas coaches. I blink. Since when does Vanitas teach me? "That way you can see what they're going to do, and you have time to counter-attack. Now, watch me, see if you can dodge."

O... Kay? I shift my weight to the tips on my toes, ready to spring any direction. I focus on Vanitas. He jumps up in the air. I know two moves of his where he does this, the one where he dives into a pool of Darkness on the ground and leaps at his opponent (usually me), and the one where he shoots blue lightning. He brings the Void Gear back, not like he's about to go into a dive, but like he's going to throw it out in front of im. I tense. When he shoves the Gear in front of him I roll under the lightning and and run behind Vanitas, striking him with SilverNight when he falls to the ground.

He looks at my critically. "Good. With your body type countr-attacks are going to be your best offense. You're quick, but not quick enough to get a hit in if your opponent isn't preoccupied. Now, come at me. I'm going to teach you some offense moves."

I straighten up and dismiss SilverNight. "Why are you helping me? You never cared about how well I fought before. Why now?"

Vanitas scowls. "Because in order for our mision to be a success, you have to be able to fight. Why are you questioning help, anyways?"

"Because it's you who's helping me."

"Just get down and attack me!" He snarls.

So we continue, me trying to attack him and Vanitas hurling insults and pain at me. We switch back and forth between offense training and defense practice. I eventually manage to get three successive hits at him by the time he calls it a day.

"Be here at seven tomorrow morning," He orders.

I just nod and dismiss SilverNight. I wander to the top of the mountainous world, gazing down at the desolate, forgotten Keyblades there. I think about how each one represents a different person, a different heart. All gone now, because the Light and Darkness can't get along.

What does that make me then? I gently place a hand in the center of my chest, the rhythmic beating there comforting me. I'm both Light and Darkness. A perfect mix. Twilight. My heart is divided though; I can feel it waging war against itself. Both sides influence my actions. It's so hard to keep me... Me.

"Onix?" The voice rouses me from my internal musings. A wind sweeps by and I feel the cold trails down my cheeks. I've been crying. I let my black, silver streaked hair fall in my face, hiding it from Vanitas.

"What do you want?" I hear the thud as he sits next to me. He leans towards me and tries to see through my curtain of hair.

"I want you to tell me what's wrong." Vanitas tries to brush my hair from my face. I sharply tun my head away from him.

"Nothing."

"Bull. What's wrong?" His deadpan, look-at-me-I'm-so-serious voice makes me chuckle slightly.

"Fine. Nothing you'll be able to understand." Even if I've been here for several months already, me and Vanitas don't get along that well. But on occasion we manage to have a laugh or two. Usually him while he's calling me weak or wimpy or something or another.

I stand up to go somewhere else, but a gloved hand grabs my wrist and pulls me back down. Vanitas take hold of the side of my face and forces me to look at him. His golden eyes burn with unfamiliar compassion and worry. "What's. Wrong?"

I jerk my face away and lean back against the ground, leaving my legs to dangle over the edge. I look at the clouds above. They swirl in the same formation they always have, the tornado like funnel that never seems to get any closer to the ground. Like all my thoughts. Forever going. Forever mixing. I can't seem to keep them untangled.

"Onix." His voice brings me back. What was the question aga- oh, yeah.

"I don't even know, Vanitas. I just... don't..." My voice cracks. I stop before I embarass myself further. A hand worms itself between my back and the ground, and starts gently pushing against my spine. I obey and sit up, suddenly feeling drained and empty.

"Um... Well... I'm not very good at the whole comfort thing..." Vanitas begins. I chuckle. Is anyone here good at that? "But... Uhm..."

I giggle and stand up, easily slipping from Vanitas's considerably more loose hold on my wrist. "It's okay. You're trying. Anyways, I have to get up early tomorrow for another long day of beng called 'weakling' over and over. 'Night, Vanitas!"

I hear him shift to look at my retreating back. "You know I don't mean that, right?"

I scoff and roll my eyes. "No, you do. Don't bother lying."

Nothing. I grin and go to bed, ignoring my heart beating wildly in my chest.

Man, you are bipolar.
Shut up.

The next morning.

I step onto the Badlands at precisely seven sharp. Both the Master and Vanitas wait, both with their Keyblades drawn. A heavy tension weighs down the air. Vanitas has his helmet on, and his face is turned towards teh gound. he's not looking at me. Master Xehanort steps forward.

"I'm sorry, my dear Onix. But I'm afraid this is necessary."

I tense. They lunge at me simultaneously, Keyblades extended. Then... Nothing.

... Man, I think this prologue is going to be the longest chapter. Aside from the epilogue. Maybe. I just kinda wanted to get Onix's time with Xehanort and Vanitas out there, ya' know? Or maybe you don't. And yes, Onix talks to herself. I have no excuse, except I couldn't bear to take any of it out. Please review. And I know prologues are generally short but... I'm starting a new trend.
