Petrus Leander, a tenured purveyor of the Practical Theology field, has participated in several primate retrieval operations across the New Frontier and has now committed to their liberation efforts on Earth. Having always lived within the Doctor caste, Petrus was raised in an environment of empathy and good will, and those values led them to join the Critical Earth Expedition. Now, as their mission leads them to Earth, Petrus and the Doctors are dedicated to the liberation of the primates in captivity there.
