Before the Dawn of the Æsir, the great machines called the "Children of Ymir" stalked Earth, bent on destroying humanity. As the war escalated, man and machine exchanged nuclear and anti-matter weapons, leaving a once-lush world frozen in a thousand-year winter. Humanity now teeters on the brink of extinction. Earth's population is now only a few million sheltered in the walled enclave of Midgard. The great sentient machines have prospered in the eternal winter. Humanity, however, is not alone. They pray to the Æsir and faithfully worship the great Organically Distributed Intelligence Network. As protectors, it is the Æsir's duty to ensure humanity survives. Their cybernetically-enhanced bodies and minds make them far more powerful than mortals, and they are properly revered as gods.
