Mercury Henricus, a tenured purveyor of the Geological Science field, has participated in several primate retrieval operations across the New Frontier and has now committed to their liberation efforts on Earth. Born into the Pioneer caste of Apskellion Space Apes, Mercury's colony was sacked by a faction of Zealots, and they were taken in by the Doctors when they came to help. Now, as their mission takes them to Earth, Mercury 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.
