Villagers in this state will soon succumb to death unless they're placed beside their homes. Cast heal miracles on villagers in these states for large belief scores. When villagers' lives drop to 0 percent, they'll die. Unless a supernatural event causes this to happen, you won't need to worry about such deaths. Death, in a peaceful village, will normally come only when villagers' ages reach into their 70s or 80s.
Sacrificed corpses are an easy way to accumulate prayer power.
When villagers work, they become fatigued. When a villager's fatigue becomes too great, he or she will seek out food, which will instantly remove all of the fatigue. Villagers won't use the food supply of a neighboring village. Villagers who are completely fatigued won't die but will be useless for almost any task. If a food supply is readily available, however, you won't need to concern yourself with the fatigue of your villagers.
