Trace Riley, a veteran activist of the Universal Primate Captivity Crisis movement at Chaugnaros University of Phoenix, has been on several primate retrieval operations in the 17 years since earning their Transdimensionallity Doctorate. Having been exposed to much violence as a native of the Zealot caste in their early life, Trace fled and sought refuge with the Doctors, where they learned to help others. Now, as their mission takes them to Earth, Trace and the Doctors seek to confront the Homo Insipiens for their failure to free their captive primates as they had promised to do so long ago.
