The term 'household slave' is a reference to an ESNE, which was a type of servant in medieval Europe. An ESNE was typically owned by a lord or nobleman and was responsible for a variety of tasks, such as cooking, cleaning, and caring for animals. They were also expected to provide labor for the lord's estate, including farming and other manual labor. Esnes were not considered to be slaves in the traditional sense, but they were still bound to their lord and had few rights.
