Homid Gifts involve humankind's skills and abilities not only as toolmakers and cultural beings, but also as conquerors of nature. Humanity's adversarial stand against nature has given them great control over their environment, but also a vague disquiet within their souls. Such are the repercussions of severing their primordial relationship with nature. Humans have become strangers to the world of spirit. Thus, many of the homid breed's Gifts are taught by their ancestors rather than by nature spirits.
