Yost Cabott, a veteran activist of the Universal Primate Captivity Crisis movement at Canis State Consortium of Aries, has been on several primate retrieval operations in the 24 years since earning their Social Sciences Doctorate. Having been raised up in the Zealot caste of the Apskellion Space Apes, Yost fled to find purpose with the more empathetic Doctors, eventually joining the expedition to free the primates of Earth. Now, with the fate of the Earth primates in the balance, Yost hopes to right the wrongs that were borne upon them by the Homo Insipiens.
