Chapter 2: A little elf girl gets sick in public, then goes home, where she soils her bed.
Chapter 3: A rich merchant and several of his guests get sick at a dinner party.
Chapter 4: The rich merchant's servants and his infant son get sick. Lots of accidents and desperation.
Chapter 5: The merchant's wife becomes ill and has an accident during anal sex with the butler.
Chapter 6: A band of orc mercenaries gets sick after leaving town.
Chapter 7: As he leaves town, the saboteur finds an accomplice, and seals the deal by raping his new bitch boy and giving him a piss enema and a special parasite.
