As a dedicated student of the sciences, Marcellus Brendanus earned their Cosmology Doctorate from The Institute of Lockeheathe in order to better serve the needs of their people as they travelled the cosmos. 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, with the fate of the Earth primates in the balance, Marcellus hopes to right the wrongs that were borne upon them by the Homo Insipiens.
