Sigurd Mensa, a veteran activist of the Universal Primate Captivity Crisis movement at Gravitron Medical School of Leo, has been on several primate retrieval operations in the 30 years since earning their Agricultural Science Doctorate. As a member of the Doctor caste, it was always Sigurd'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, Sigurd hopes to right the wrongs that were borne upon them by the Homo Insipiens.
