I have an idea it sucks but it is a theory, I remeber reading where it said that the keyblade had two stories one where the wielder brought peice to the world but another were they brought ruin upon it. Maybe the knights are the other part to the story, please dont be mift if it has already be disscussed or proven false........ I been off for a long time I just barley was able to get back online as of yesterday
