Everyone and his dog has probably figured this out, but ZI havn't and I want to know. In the original KH the sumoning gems came from people whose hearts were so strong, that when their world was destroyed and their bodies obliterated, they became gems. But in KH II, they said that when a strong person loses their heart (and I presume that that's what happens when a world is destroyed because that as close to "death" as these games seem to get) a Nobody is created. How is this possible? Shouldn't Simba and co. have turned into Nobodies instead of gens, or don't animals become Nobodies? I DON'T GET THIS!!!
