The Knight represents the highest social class of the group. In medieval society, knights were considered to be part of the nobility and held a high position in the social hierarchy. They were typically wealthy landowners and were often associated with chivalry and honor. The other characters mentioned, such as the Squire, Monk, and Miller, may hold certain levels of status but do not possess the same level of prestige and social standing as the Knight.
