"Okay, uh-- short version, yeah, they're the bad guys, but they're uh... they're also people from the carnival, is the thing? So we can't kill 'em. It's..."

She sighs, and Screamo squeaks a couple times. Miko glances down at her, frowning. "Yeah, I know, I know, I'm gonna explain. So-- a bunch of people from the carnival got corrupted by this Void thing, 'n this lady Cy-Ren is controlling them now, and that's why they're wearing black and screwing stuff up. On the other hand some of us - like me - got picked by Creation, that's like, life and stuff, to keep 'em from screwing stuff up, but since they're screwing everything up everywhere and most of us don't even know what we're doing, more help would be appreciated? We just gotta stop 'em without killing 'em."

Simple enough, but really not, honestly.
