Missus dominicus
A missus dominicus (plural missi dominici), Latin for "envoy[s] of the lord [ruler]", also known in Dutch as Zendgraaf (German: Sendgraf), meaning "sent Graf", was an official commissioned by the Frankish king or Holy Roman Emperor to supervise the administration, mainly of justice, in parts of his dominions too remote for frequent personal visits. As such, the missus performed important intermediary functions between royal and local administrations.
