Pancras Salem was present when first contact was initially made with the Homo Insipiens of Earth, and after having earned their Aerospace Engineering Doctorate from GALT Hines College of Medicine of Sagittarius they have joined the expedition to return and bring the venture full circle. Having always lived within the Doctor caste, Pancras was raised in an environment of empathy and good will, and those values led them to join the Critical Earth Expedition. With the Critical Earth Expedition underway, Pancras will do what they can for the sake of captive Earth's primates.
