Marsilius Jasper, an up and coming purveyor of the Microcosmic Virology field, learned of the Universal Primate Captivity Crisis from activists attending Auai'aine Research Observatory of Equuleus and joined the expedition to free the captive primates of Earth. As a senior expert in their field at the Black Hole-2 Bastion, Marsilius dropped their post without delay upon learning of the Critical Earth Expedition. With the Critical Earth Expedition underway, Marsilius will do what they can for the sake of captive Earth's primates.
