A Long time ago, when the worlds were still one. There existed a weapon known as the X-Blade. The X-Blade was the only way a person could access Kingdom Hearts, the source of all light in the worlds. A fatal war over the possession of the X-Blade left the world in total darkness and the X-Blade was scattered in 20 pieces, 7 of light, 13 of darkness. The World was restored by the light within the hearts of children, but many worlds separated from each other. The War was soon passed into legend, told as a warning to new Keyblade Wielders.

But some legends say of a secret 21st piece that was scattered as well, one of not light nor dark, but of inbetween. It is not needed to reforge the X-Blade, but is needed to unleash it's full power.

In the middle of nothingness, a black abyss, stood a large column. Three figures stood on it, all in cloaks, one in white, one in black, and one in grey.

"So you both have chosen your wielders?" The grey one asked.

"Yes. My wielder is a powerful person, he may be a bit naive, but he has light in heart." The white one responded.

"I was originally found by accident by another wielder, but soon came into the possession of my current one." The black one added. "Why haven't you found a wielder yet?"

"I haven't found him one who can truley wield my power." The grey one responded. "I haven't found him yet due to my current predicament, forces of unknown allignment have sealed me away, trying to hide my power. But they do not know that I can still influence my wielder."

"Are these forces of the dark?" The one in black asked.

"No, they seem to use a new kind of power that is out of our reach." The grey one told. "Wait. I sense someone watching us."

"Who? The unknown forces?" The one in white pondered.

"No, it is the one who can wield my power. He has finally arrived." The grey one told them. The whole station soon disappeared, then a boy appeared, falling. The Grey Cloaked figure appears and grab his hand. "You may not remember me, but remember my words. The closer you get, the more dangers will appear along your path. Then nothing.
