Create a sub-rule of “Occupations” titled “The Master of Hounds” with the text:

The Master of Hounds (if living) may secretly inform the mayor of the status of the hounds. The hounds may either be “penned” or “released”. The hounds are “penned” unless otherwise specified. Whenever a villager is savaged by werewolves, if the hounds are released they begin to howl, chase, and corner their suspect. The Mayor shall make a story post indicating the name of the villager the hounds have cornered. There is a 30% chance that the cornered villager will be one of the werewolves involved in the attack, otherwise it will be a random living villager.
When the hounds are penned, the Master of Hounds may pen them outside the house of a living villager of their choice (themselves unless otherwise specified). The name of the villager whose house the hounds are penned outside of should be sent to the Mayor privately. If a villager who has hounds penned outside his house would be Bitten or Savaged by werewolves (or if they are a werewolf and they would Bite or Savage another villager) the hounds begin to howl, alerting the village and preventing that the Biting or Savaging. The Mayor shall then make a story post which identifies the name of the villager who has the hounds penned outside their house.
