Named for the goddess and personification of the night. She was a daughter of Chaos and had many children by her brother Erebus, who personifies the subterranean darkness. The realm of Nyx was in the far West, beyond the land of Atlas.

Darkness.  Night.  The unseen but accessible.

This is the mother of Hecate
