In Greek myth, KHAOS (or Chaos) was the first of the primeval gods to emerge at the creation of the universe. She was followed in quick succession by Gaia (Earth), Tartaros (the Underworld) and Eros (Love the life-bringer).
Khaos was the lower atmosphere which surrounded the earth—invisible air and gloomy mist. Her name khaos literally means the gap, the space between heaven and earth. Khaos was the mother or grandmother of the other substances of air: Nyx (Night), Erebus (Darkness), Aither (Light), and Hemera (Day), as well as the various emotion-affecting Daimones which drifted through it. She was also a goddess of fate like her daughter Nyx and granddaughters the Moirae.
