It strikes me that there's no real repository of information like this. I love playing off the cuff as a GM, but one thing I can't pull out of thin air is NPCs. If I do—if I try to run them without motivations and personalities I've worked out ahead of time—they're never as good as they could've been.
Does anyone have anything to share? I'd love to see it, regardless of if it has setting information or not. Generic is boring.
