"Heartless are... they're Heartless." Sora waved a hand in the air, trying to illustrate a point he hadn't had to explain in a long time. "They come from the darkness in people's hearts, and they want to... eat hearts, I guess. It's a little more complicated than that but I don't think much." Nobodies were the complicated part. And boy, were they. "What they really want is to consume the hearts of worlds. They want everything to be dark."

And that was as good a time as any to call the Keyblade, in its swirl of light, as Oathkeeper, one of its more impressive forms. And a nice reminder that he had to see Kairi again, to return the keychain she'd lent him so long ago. "I use this to destroy them, free the hearts they take, and lock them out of worlds. It's called the Keyblade."
