A prominent figure in the field of Philosophy, Horsehead Melvinus became an activist in primate liberation after completing their tenure at Xenthalius Seminary of Pyxis. Borne into the Doctor caste, Horsehead was taught to always seek ways to help others regardless of their differences, a core value that led to their interest in the Universal Primate Captivity Crisis. Now, with the fate of the Earth primates in the balance, Horsehead hopes to right the wrongs that were borne upon them by the Homo Insipiens.
