Ra'el Sha was a term in the Dreman language meaning "living dead". Dr. Sarjenka used this term in reference to Crewman Fabian Stevens, whose entire body had been paralyzed by an Ardanan parasite that had infected his brain and his reticular activating system. Such a vegetative state was considered by the Dreman people to be a fate worse than death. (CoE eBook: Signs from Heaven)
