Wormwood Tavi first became aware of the Universal Primate Captivity Crisis while on a remote 10-year study abroad venture at Blueshift Dexley Corporation of Pyxis where they earned their Metaphysics Doctorate . Having always lived within the Doctor caste, Wormwood 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, Wormwood 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.
