Burton Aquila has long been dedicated to their studies in Computer Science but has always held an interest in the Universal Primate Captivity Crisis and has now become committed to a missionary in the Doctors' liberation efforts. Having always lived within the Doctor caste, Burton 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 takes them to Earth, Burton 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.
