Woah, I've been playing KH2 for so long, I totally forgot about the grandmother's tale in the first game. Anybody remember it? Well, what if it has something to do with KH3? This is only my thought, DON'T KILL ME!!! I don't even have enough info to even guess as to what KH3 could be about.

"Long ago, people lived in peace, bathed in the warmth of light. Everyone loved the light. Then people began to fight over it. They wanted to keep it for themselves. And darkness was born in their hearts. The darkness spread, swallowing the light and many people's hearts. It covered everything, and the world disappeared. But small fragments of light survived... in the hearts of children. With these fragments of light, children rebuilt the lost world. It's the world we live in now. But the true light sleeps deep within the darkness. That's why the worlds are still scattered, divided from each other. But someday, a door to the innermost darkness will open. And the true light will return. So listen, child. Even in the deepest darkness, there will always be a light to guide you. Believe in the light, and the darkness will never defeat you. Your heart will shine with its power and push the darkness away."
