Servado was a being of unknown origins.
Near the end of the Roman Empire's rule in Hispania, Servado assumed humanoid form and organized the defense of people in Hispania against barbarian invaders. Eventually Servado called in the Preservers to save the local Human population and sacrificed himself in a one man stand. These actions deified Servado in the eyes of the rescued Humans, who were moved to Meramar. (TNG novel: The Captains' Honor)
- It is unknown if Servado was a member of the Preservers or not.
