A prominent figure in the field of Practical Theology, Reva Hopkins became an activist in primate liberation after completing their tenure at First Order Department of Science of HD 139691. Having been raised up in the Pioneer caste of Apskellion Space Apes, Reva retired from the galactic frontier to perform good deeds with the Doctors and joined the expedition to free the primates of Earth. With their sights now set on Earth, Reva and the Doctors will do what is needed to bring freedom to the wrongly imprisoned primates that remain.
