Keeeyblade Waaaar. Not that Sora's ever been too clear on the details about that, but he does know that there was a large scale war, and that probably explains a whole lot of things.

Sora pauses. "You know. I think things might have been okay." He thinks about it for a moment, really hard. "Sorry, my memories from then are really scrambled? I don't know when things were supposed to begin or end." He closes his eyes. "I know we saved the worlds from the darkness the first time around. We had to... hm. Free their hearts." And that took a bit of doing that he doesn't think will fit the space of one conversation. "And all the hearts went back to where they were supposed to be. Some of them were still asleep, but most of them were fine. And then... things got bad again, but it wasn't because of the darkness. And then we fixed that. And then they got bad again. And then, after that..."

Sora opens his eyes. "I don't know what happened." He thinks he may have died again, but he isn't certain. His memories don't reach that far. He isn't even certain if that was where his entire universe got obliterated by the disaster that sent his soul to Locke City or if he'd done something to end things prematurely. He'd... broken quite a few things, he thinks. "But, um, anyway. The darkness was the first thing, and that was something we definitely fixed."
