Nyx was the primordial Greek goddess of the night and a consort to Erebus, the god of darkness.
According to the writings of the ancient Greeks, she was one of the first goddesses. Connected with her consort Erebus, some held that she hatched an egg that created the Earth, sky, and sea.
She was older than even Gaia, the goddess of Earth. Since she was so primordial and powerful, she gave birth to death and fates.
Zeus even feared her because she was older and more powerful than him.
