Porgenitors were the very original template of whatever race that existed (e.g. Adam be the progenitor of humanity, Yagi Keshin the progenitor of the yagi), highly respected and indeed very power, progenitors are unique individuals to which they're capable of living potentially forever. Currently, the only known progenitors existing in the present is Skogtroll, Yagi Keshin and Yagiōkami.
