Resources & fortifications
Next to the steading's Prosperity, you'll see a list of resources (farming, hunting/ trapping, stone from the Old Wall, etc.).
Next to the steading's Defenses, you'll see a list of fortifications and other elements that help keep the village safe (the village militia, the Ringwall, etc.)
As you establish new resources, fortifications, or other defensive elements, you'll add them here. Should the village lose these resources temporarily, it will suffer debilities. Should it lose them permanently, its Prosperity and/or Defenses will go down.
