A: The fields and farmlands are dirty places run by the serfs, indentured servants to the Lord living up in the manor house. The serfs had a rough life and had to pay harder and harder taxes, barely subsisting off of what the yfarmed.
B: The village was mostly inhabited by merchants and those who did not farm, and serfs came here to sell what goods they had excess, but they rarely had any excess after the taxes and their food were considered. In larger fiefs they were typically bustling places with many marketplaces and inns for travelers and merchants.
C: The manor house, depending upon the status of the lord, was typically either luxurious or extremely defensible, or sometimes both. In the event it was a proper castle, those from the village and fields would come and hide in it during a siege or raid, reducing civilian casualties. The lord and his family would live here, along with a garrison, if it was a castle, or guards, if it was but a manor.
