A small group of cannibals has started roaming farther out from their remote home and have come into contact with some farms. What the cannibals do is wait till dark and all the farmers have entered their home then they raid the place killing everybody. Once that is accomplished they stoke the fire of the home they just invaded and proceed to cook the former occupants and have a grand meal.
Characters can find farm houses ransacked with cooked and half eaten farmers strewn about the house. The perfect time to catch the cannibals is in the middle of one of their dinners.
