Harker Glint studied for several years at Barnard State Community College of Fomalhaut and earned their Doctorate in Neuropsychology and Mental Health, but eventually found their calling as a missionary in the Universal Primate Captivity Crisis. As a member of the Doctor caste, it was always Harker's goal to obtain their Doctorate and use their education and skills to help their own people, but upon learning of the Universal Primate Captivity Crisis, their priorities changed. Now, as their mission leads them to Earth, Harker and the Doctors are dedicated to the liberation of the primates in captivity there.
