As an expert in the field of Astronomy, Calixtus Brendanus has long been a prominent name amongst the ranks of the Doctors, and now uses that influence to help steer the focus of their primate liberation efforts. As a member of the Doctor caste, it was always Calixtus'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, Calixtus and the Doctors will attempt to put their skills and education to work as best they can for the sake of the primates there.
