this is my kh theory. iheard on one of the boards that there is a keyblade for every existence, light, dark, twilight, and other. so, every one knows how ansem is pure darkness right, and how riku was supposed to bet the keyblademaster right,and how sora is of the light right. well i think ansem was supposed to be the keyblade master of the dark but was supposed to have some light left in him keeping him from being pure dark, but he was so interesed in the dark that that light was lost and he bcame pure evil,leaving the position of keyblade master of the dark open. so riku's fate was changed so that he could be the keyblade master of the dark, and sora was chosen to be the keyblade master of the light, so when riku's fate was so suddenly changed he went berserk and opened the door to detiny islands,letting in the heartless and begining sora's story. so? what are your thoughts?
