Why do you need an item to lock the keyholes this time?

^now that makes sense^

But that's pointless. Nobodies don't go after people for their Hearts. It's like the opposite of the Heartless.

Heartless hunt down people with Hearts so they can create more. This is the reason they hunt down the Heart of a World, it's like the ultimate prize.

Ansem states that the Nobodies attack out of confusion, they have no real set goal other then to just attack.

When the heart gives birth to a "Heartless", the soul and body that are left behind are born in this world as a new existance. Unlike the Heartless they have consciousness, and though it's uncertain exactly what thoughts "that" entails, it seems they exist to bring confusion to the world.

I think the keyholes sealed in KH1 were pointless. Otherwise, why would Sora say "Our whole journey was for nothing.."

 

[keybladeboi]

um this may be a stupid q, but, if a world becomes "heartless" that means there is a world that is "nobody"... does that make sense?

 

[Americo]

Well as far as we know, we have no clue what exactly happens to a world that has lost it's Heart. We could assume that it pretty much dies. I believe End of the World (the area in KH1) is Destiny Island in the process of having it's Heart taken.

I believe it's stated that End of the World is fragments of other worlds, actually. That's why it's so weird.
