Tau Ewan, an up and coming purveyor of the Atmospheric Science field, learned of the Universal Primate Captivity Crisis from activists attending Hyteglass Scientific Institute of Sextans and joined the expedition to free the captive primates of Earth. Tau was stationed at Monsoon Clinic when news of the Universal Primate Captivity Crisis broke, and they were one of the first to join the mission. Now, with the native primates still in captivity on Earth, Tau and the Doctors venture to fulfill the promise of release that the Homo Insipiens have reneged.
