The first adventure in Pathfinder 2E's latest adventure path has the PCs leading a traveling circus. There's a plot with some villains who want to kill everyone on the Starstone Isles too ... but traveling circus! There's also a free player's guide which has new backgrounds for circus folk -- aerialist, animal wrangler, barker, blow-in, butcher, circus-born, clown, mystic seer, and rigger.
