Kin, are so called because they are the living remnants of earlier humans crafted by earlier Sun gods and goddesses. By means of some Elemental catastrophe, sometimes as a result of macky, those humans who did not die outright had their bodies contorted into different shapes which have since formed into the many animals we know today. Kin, specifically, did not bear the brunt of the disaster but still did change in accordance with their time and bare distinctly human features.
