Yeah...I'm sorry

Somewhere in a far-off world, in a far off time, the events transpiring in Remnant were nothing more than text in a book being read by a man in a black coat, someone who had been tasked with training the next generation of Keyblade wielders to help protect The Light.
He was the Master of Masters, and he was utterly perplexed by the events that had been presented to him via the Book of Prophecies.
"Well this is quite the mess that's appeared amongst my findings, I don't even remember writing these pages." The Master would continue to read on curiously, occasionally catching the odd contradiction here and there that would leave him purely flummoxed. "Wrestlers being turned into Ghouls? Siblings fighting over a guy? Parallel worlds? There's too many plot lines going on at once!" Truly it was a jumbled mess of threads not unlike the fabled Gordian Knot, however there was no one for The Master to cut through to the heart of the matter and figure out where these pages might have manifested from. "No one has access to this book except myself. And the only thing written in it are the things that my eyes foreseen, so all I have to do is give it a look and see what's going on in the future."
With that in mind he would grip the hilt of his Keyblade and focused himself as the room he was sitting in faded into nothingness before being filled in by fragments of events that had yet to come, the first thing he would see was a land under attack, black creatures were attacking fleeing people without mercy while metal soldiers fought against them in one instant then turning back to fire their weapons on those same people in the next. "Well that's not good, something's obviously gone awry in that world, but I don't think it's something we should get involved with." The Master would continue to look into the future, this time seeing a fierce battle between two women: One was a stunning raven-haired woman who seemed to have mastery over fire as she expertly dodged and countered her opponent, a redhead who was dressed like one of the warriors of old. "Now this is interesting, I can tell by the bright light of her heart that this warrior maiden could be a valuable asset to The Light." He would continue to monitor the battle closely as the tide changed to the pyromancer's favor, the darkness billowing from within caused him some concern as she took the upper hand and cornered the warrior maiden.
"It's unfortunate that you were promised a power that was never truly yours." The pyromancer would level her bow towards the warrior maiden whom, despite her injuries was still willing to fight to the bitter end. But take comfort in knowing that I will use it in ways you never would have imagined." The darkness wasn't the only thing that The Master noticed upon looking into the raven-haired woman's heart, there was a strange power that was burning inside of her that caused him to grip the hilt of his Keyblade harder in agitation.
"Do you believe in destiny?" The warrior girl was physically beaten down, but the light inside of her was burning brighter despite having been defeated. If she somehow survived this ordeal he would visit her himself and offer her a place in one of the Unions.
"Yes." The raven-haired woman answer this bluntly before firing an arrow into her opponent's heart, leaving The Master to silently lament over the loss of a brave soul. However, his sadness would be delayed by the sudden appearance of two strong auras: One of the bright light of innocence, a heart that believed in a bright future even as she arrived on the scene. The other radiated a hollow darkness that had seen hardship and tragedy, but he saw the tiniest speck of light that struggled to hold on.
"This can't possibly end well." He would watch as the Light was revealed to be a crimsonette-haired young woman wearing a red hood and wielding a similarly colored scythe, the Darkness belonged to a silver-haired young man who gripped the hilt of an onyx colored blade. Both sides would watch on horror as the red-haired warrior was rendered to nothing but embers of orange light, and while the red-hooded simply stood there in stunned silence, the boy would let out a strangled howl of rage before charging recklessly at the raven-haired woman only to receive a fiery-handed slap to the to the face and sending her would-be assailant to the ground in a screaming heap of agony. "Not the sharpest tool in the shed that one."
However, this action would prove one-step too far for the red-hooded girl as her "Light" seemed to spike from a lonely candle to a raging inferno as a burst of power flowed forth from her small frame, surprising the raven-haired individual before she and the screaming young man were enveloped by the light and causing even The Master to look away as he broke his connection to his future sight. "What in the world just happened, and just what kind of power was that?" He would sigh and begin looking through the Book of Prophecy carefully, he wondered if these events were also covered within the pages he had no memory of writing.
"A red-hooded girl who exudes a bright light that's unlike anything I've ever seen, a boy who's losing the fight between light and darkness, and that woman..her power isn't normal either." The Master would sigh, seeing his Keyblade out of the corner of his eye and wondering what to do with the information he'd gathered from his sight and looking down at the book hesitantly.
"I've been given the gift of Foresight, and everything I've seen has been written here in the Book of Prophecy." The Master would take his pen and look down at the pages involving Remnant, his pen hovering just close enough to begin writing.
"What to do, what to do."
Yeah so when Lady Luck ended up picking THIS story, I found myself at a loss as I had forgotten my initial plans for this story then when I started mentioning things in Addiction and then teasing TaiyangxCinder i knew I'd gone way off the rails.
So I'm leaving it up to you guys to figure out where this story should go: A. Keep going with Xehanort v. Cinder? B. Pursue the CinderxTaiyang angle? C. Trash it. There's probably a poll up on my profile page by the time you're done reading this so check the profile page.
Again, really sorry.
