From years 167 CNY to 1359 CNY, starting with the formation of the Great Cloud and ending with the Great Broadening.
Forming of the Great CloudEdit
Daranosh slays the first two mortals, the mother and father of all people, and seals up the Sky Mountain Element. A Black Cloud pours out of the mountain, covering all of Atanoah in darkness. The Elements do burn segments of the cloud cover away after three days, however, and keep it at bay to form the Light Regions. Millions die, the only place people are left living is in Two Edged, since none one had ever bothered traveling far enough to other areas where Elements burned. Those living must breathe in faint fragments of the cloud, mortally damaging their bodies and taking immortality away from humanity.
