Aquarios Albertus, a veteran activist of the Universal Primate Captivity Crisis movement at The University of Stellar Lato, has been on several primate retrieval operations in the 22 years since earning their Civil Engineering Doctorate. A child of the Pioneer caste of Apskellion Space Apes, Aquarios was stranded in a colonization disaster and adopted into the Doctor caste, but awaits the day that they can rejoin the Pioneers on their venture into unknown regions of space. Now, as their mission takes them to Earth, Aquarios 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.
