After the first great battle and temporary death of Discord, Celestia and Luna healed the burning earth and began anew the task of creation.
In this second Age, they created creatures out of mere matter through the uteri of their own bodies, but found they decay quickly. They then created creatures that could repeat themselves, and in a short time repopulated the earth.
At the beginning of the universe, there were the sisters Celestia and Luna, on the Akun Mountain. There were no creatures under the heavens, so they discussed about becoming married [to populate the earth], but felt it might be improper. So they climbed to the top of Akun, set up two smoking fires, and chanted, ’If the heavens permit us to become couples, then let the smokes converge; if not, let the smokes diverge.’ and the smokes converged. Luna thus came to Celestia, covering her face with a fan made of weaved grass, and they became the first couple. They devised the rituals for proper marriage, and taught them to the creatures that came after them.
Fuxi and Nüwa were the original humans who lived on the mythological Kunlun Mountain. One day they set up two separated piles of fire, and the fire eventually became one. Under the fire, they decided to become husband and wife. Fuxi and Nüwa used clay to create offspring, and with the divine power they made the clay figures come alive.
