Author's note: Welcome to my Kingdom Hearts story. Since an official Kingdom Hearts III maybe in the near future, I present my own version of it. Note that this disregards Birth by Sleep and the yet unreleased Kingdom Hearts coded since I have yet to play it and this has been in my mind for a long time since before I heard of them. A few common elements will be used but not in any major capacity.

Disclaimer: I do not own Kingdom Hearts or any of the characters in this fanfiction. They all belong to either Disney or Square Enix.

Kingdom Hearts III:

The Great War of Darkness and Light

A fanfiction by Mad Dr. Matt

Prologue

From the writings of Master Yen Sid:

There are many great tales that surround our universe and its many worlds. Within each world, an amazing story unfolds. But none of the stories is greater than the one that unites them all: the story of Sora the Hero of the Keyblade.

The legend of the Keyblade is known well throughout the worlds so it is surprising that it would choose someone as young as Sora. Even I was surprised to learn that the Keyblade had chosen the young boy from a peaceful archipelago of islands.

However, Sora's endeavors have proven that age has nothing to do with the strength of a heart. And it is thanks to Sora, that the worlds lost to the darkness have been restored and the threat of Organization XIII has been eliminated.

It is also important to commemorate the ones who gave Sora tremendous assistance in the quest to vanquish the darkness. His closest friends Kairi and Riku as well as the brave trio from Disney Castle, Donald Duck and Goofy as well as my former apprentice King Mickey all deserve recognition for their efforts. Other valiant souls throughout the worlds also should be recognized so it is important that the exploits of Mulan, Tarzan, Jack Sparrow, Hercules, Auron, Ariel, Aladdin, Cloud, Simba, Tron, Jack Skellington, the Radiant Garden Restoration Committee and others who played a part in Sora's victory over the Heartless, the Nobodies, and of course, the prime mover among all of them, Xehanort be acknowledged.

But though the worlds are currently at peace since the fall of the Organization, I regret to say that an even greater crisis is on the horizon. The Council and I all believe that the threat caused by Xehanort has not yet passed and I regret to say, that the worlds will have need of Sora and his friends.

It is unfortunate that this burden falls on the shoulders of ones so young. But Sora and his friends have proven that they are up to the challenge. I have notified the King and he in turn has sent word to Sora. All that is left to do now is wait.
