Concept: “Let us return to the city where we may meet visitors from other places … and kill a few of them.”
Content: More NPCs, hirelings, rumors, and sites to populate the city
Writing: Descriptive text provides motivations and hooks, with many unique special abilities
Art/design: A mix of colorful weirdness for major NPCs and more subtle, baroque art for the rest
Usability: Will often refer you to Strange Citizens, so make sure you keep that volume handy
