Y'know those Knights in the secret ending? I think those knights (if they're not Chasers) will be the main characters of KH3. Like a prequal, KH3 could be about the history of previous Keybladers. I also have another theory. Each of their Keyblades represent Light: Kingdom Key, Darkness: Mickey's Keyblade, and Twilight (Dawn): Riku's Keyblade. As the story progresses, you may have to switch gameplay between each of them. I know it sounds stupid, but this is the **Spoiler** Forum right?
