Marcellus Mahomet has long been dedicated to their studies in Civil Engineering but has always held an interest in the Universal Primate Captivity Crisis and has now become committed to a missionary in the Doctors' liberation efforts. As a member of the Doctor caste, it was always Marcellus'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 takes them to Earth, Marcellus and the Doctors seek to confront the Homo Insipiens for their failure to free their captive primates as they had promised to do so long ago.
