As an expert in the field of Medicine, Hero Servatius has long been a prominent name amongst the ranks of the Doctors, and now uses that influence to help steer the focus of their primate liberation efforts. Having lived life among the Pioneer caste, Hero had helped to settle many new colonies in the galactic frontier, but decided to find a new purpose helping others with the Doctors. Now, with the native primates still in captivity on Earth, Hero and the Doctors venture to fulfill the promise of release that the Homo Insipiens have reneged.
