5 new roles for the villagers: the idiot, the elder, the piper, the scapegoat, the savior
9 new variants/playing suggestions, e.g., playing in the dark with a candle in front of each player's face and blowing the candle out when the player dies, or instead of the werewolves eating civilians, they contaminate the civilians, leaving them without rights or powers
