Nyx

Hesiod's poem Theogonia ("On the Origin of the Gods" or also "The Birth of the Gods") describes the origin of the Nyka as follows: "In truth at first Chaos came to be, but next wide-bosomed Earth, the ever-sure foundation of all the deathless ones who hold the peaks of snowy Olympus, and dim Tartarus in the depth of the wide-pathed Earth, and Eros, fairest among the deathless gods, who unnerves the limbs and overcomes the mind and wise counsels of all gods and all men within them. From Chaos came forth Erebus and black Night; but of Night were born Aether and Day, whom she conceived and bore from union in love with Erebus ..."

First, then, was Chaos (the abyss, the unstructured abyss, the antithesis and precursor of the cosmos). Then was born the Earth (Gaia) and in it the Underworld Abyss (Tartarus), and then Love (Eros). Next, out of Chaos is born Darkness (Erebos) and Night (Nyx).

With the Darkness (Erebos), Nykta gave birth to Aithera (Light) and Hémera (Day). Nykta had many other children with different fathers (Zeus, Erebos, Uranos, Tartarus). The beings she fathered are mostly associated with death and are in the realm of darkness and horror (Tartaros). Known descendants include: Nemesis (goddess of retribution), Charon (ferryman of the dead to the underworld), Hypnos (god of sleep and sleep itself), Apate (goddess of deception and deception itself), Thanatos (god of death), etc...
