Divine spectrum
In Hesiod's "Theology", she is the daughter of the chaotic god Caos and a goddess dressed in black. In Orphism, Nix is regarded as the supreme deity of the tripartite goddess, possessing three different supernatural identities. She can be the goddess of numbers - Ananke, the goddess of retribution - Adrastea, and the goddess of cause and effect - Hemarmene.
[Note 1: Nix's three supernatural identities belong to the Trinity, representing his different manifestations as the Supreme Goddess.]

Nix (ancient Greek: Νύξ， Nyx, the earliest god born, was Caos, representing the emergence of the universe. Then Gaia, Tartaros and Eros were born alone. Afterwards, Caos gave birth to Eribos and Nix alone. [2]
Nix and her brother Erebus represent the dark side of Caos. She and Erebus gave birth to Aether and Hemera (see Hesiod's Divine Manual). There are also myths that Hesperides, Shepnos, Tanatos, Moirae, Hecate, Geras, Eris [3], and Caron (see Juvenal 3.267; Eustatius on Homer 1666) [4] were also born by them. And Nikes herself has also given birth to many strange children - most of whom are not unattractive evil gods.
Some of her children joined the ranks of the heavenly gods, while others became the underworld gods. Although the Nix family was not on par with the gods of heaven, earth/sea, and the underworld, their influence cannot be underestimated. Not only Hades, but also Zeus, the king of the gods, had to weigh their own weight.
In classical art, Nix is a woman wearing a black starry veil, embracing a young god of sleep or death, and flying up to the sky every evening in a carriage pulled by a black horse.

In Greek mythology, Nix was a very ancient and powerful god, who was the original source. Nix not only holds a noble position, but is one of the few great deities in Greek mythology that possesses powerful power in all mythological systems. He also possesses powerful power that simultaneously constrains mortals and gods. Due to his power and identity, Zeus was afraid of three parts.
Homer mentioned in the Iliad that only Nexus, who "subdued everything," held the Heavenly Father Zeus in reverence. (But in the Divine Book [2], it is said that Zeus also respected Hecate and Heracles.) Because Hera wanted to kill Heracles who had left Troya and returned by sea, in order not to be discovered by Zeus, she let Sepnus put Zeus to sleep. When Zeus woke up, he learned that Heracles had been scraped to Kos. In anger, he hung Hera in shackles on Olympus Mountain and threw Sepnus down on Olympus. He was not yet relieved and threatened to drive Hypnos into Tartaros. Xu Punos had to hide in his mother Nikus' robe so that Zeus could not find him, and Zeus, due to his respect for Nikus, gave up on it.
Nix resides in the underworld, and her residence is also filled with darkness. Whenever the evening star Hesperus opened her way, she left the underworld, flew up to the sky in her chariot, covered the earth with night, and immersed the world in peace. Nix is ancient and powerful, and even Zeus, the Heavenly Emperor, respected her three times.
In the ancient genealogy of Orpheus esoteric religion, Nix was the original source and an equal existence with the time god Kronos. In the Orpheus Divinity Manual of Holy Words, Nix has three different supernatural identities (three phase gods) at the same time. She can be the wife of Kronos and the mother of Farness - Akenan, the goddess of certain number, and his wife - Adrastya, the goddess of natural law, and her daughter - Hemalmene, the goddess of causal destiny. In fact, Farness was evolved from Eros, but in the ancient version, Eros is usually the son of Nix (sometimes confused with Aphrodite). In esoteric teachings, Nix was also regarded as the foster mother of Zeus [1] [5].
Nix combined with Erebus to give birth to Aether and Hemera, the goddess of the day. She also gave birth alone to a large number of evil gods who harm the world.
