(n., adj., formal)
A Kindred who receives territory (and sometimes title) from a lord (q.v.) through feudal tenure on conditions of homage, allegiance and sometimes corvée (q.v.). Casually, any directly subordinate Kindred in the feudal hierarchy, or any vampire at the “lower” position in a feudal bond (q.v.). In practice, all Kindred in a city’s feudal hierarchy are vassals to some lord, except for the Prince from whom all vassalage descends. “I am Delacroix, vassal in Edgeville to citizen Carver, vassal in Druid Hills to the lady Sycorax, and Hound to our Prince.”
