As an expert in the field of Architecture, Trace Sagan 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. Borne into the Doctor caste, Trace 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 native primates still in captivity on Earth, Trace and the Doctors venture to fulfill the promise of release that the Homo Insipiens have reneged.
