Diseases

Across Aerith sickness moves with the same quiet certainty as the seasons. Every region has its own troubles shaped by climate by crowding and by the way people live upon the land. Illness does not sweep across the world all at once. It rises in pockets. It settles in valleys. It follows caravans and ships and then burns itself out as quickly as it came. Most people learn early that survival depends on respect for what cannot be seen and cannot be fought with blade or shield.
  Rural communities face sickness shaped by the land itself. Cold seasons in the mountains bring fevers that root deep in the lungs. Long winters force people to gather indoors where coughs spread quickly. Farmers know how to treat minor ailments with herbs salves poultices and steam drawn from simple broths. These remedies do not cure everything but they keep a household steady until a healer arrives. The knowledge passes quietly from parent to child just as essential as knowing how to plant or how to mend a fence.
  In the plains different troubles rise. Warm weather and standing water bring waves of sickness carried by insects. Harvest seasons strain the body and leave people vulnerable to creeping fevers that move through whole villages. Here healers rely on bitter teas fire dried herbs and long rest. They teach the value of clean water shaded rest and distance from the ill. These lessons are not superstition. They are the result of generations learning the hard way how fast sickness can spread when ignored.
  Coastal settlements fight their own battles. Ships bring trade and culture but they also bring foreign fevers and stomach sicknesses that find eager footing in crowded ports. Salt air helps but it does not stop everything. Towns often maintain small infirmaries near the docks where dedicated healers watch new arrivals for signs of trouble. When sickness takes hold it moves through cramped alleys and densely packed homes with frightening speed. The only defense is quick isolation steady care and a community willing to listen to the warnings of its watchers.
  Cities carry the greatest risk. Crowding poor sanitation shared wells and constant movement of people make urban illness a constant threat. Coughing fits that begin in a single block can spread across districts within days. Waste left too long can poison entire neighborhoods. Most cities employ trained healers monks or learned herbalists who oversee basic cleanliness and respond to outbreaks before they grow. Their work is quiet and often thankless but it prevents disaster more effectively than any wall.
  Magic offers some protection but not enough to change the world. Most casters do not possess healing arts strong enough to cleanse disease from whole communities. Spells can save a life but they cannot stem a wave of illness when it rises. As a result people rely more on practical wisdom than on miracles. Fresh air. Boiled water. Clean bedding. Separation of the sick from the well. These simple acts hold more power than any charm when sickness moves through a region.
  Illness in Aerith is not a story of plagues and catastrophe. It is a constant challenge that shapes how people live and how they care for one another. Every village and every city knows that sickness is as old as the world itself. It demands respect. It demands caution. And in the end it reveals the strength of a community far more clearly than any battle ever could.
