I wonder how the Keyblades in the Keyblade Graveyard work? Xehanort uses a bunch of them to attack in Birth By Sleep, so does that mean they can be take out of the ground and used individually? If so, can they be claimed by another Keyblade user? I would think they can't, but maybe I'm wrong. My personal theory is that they can be used, but they won't teleport back to the user if it's knocked out of their hands. What are your thoughts?
