Riven Dutch, an up and coming purveyor of the Intergalactic Language field, learned of the Universal Primate Captivity Crisis from activists attending Hammond-Hail University of Science and Medicine of Pisces and joined the expedition to free the captive primates of Earth. Having always lived within the Doctor caste, Riven was raised in an environment of empathy and good will, and those values led them to join the Critical Earth Expedition. Now, with the native primates still in captivity on Earth, Riven and the Doctors venture to fulfill the promise of release that the Homo Insipiens have reneged.
