Oh, not at all. Where I come from, Darkness is the result of all the nasty feelings that rose up in people's hearts. Anger, sadness, jealousy, they all contributed to make it. And if a World has too much Darkness swirling around? Poof! No more World, and anyone who doesn't escape becomes a Heartless too.

But it's strange, I'm not sensing even a hint of it in this World. That shouldn't be possible.
