In Greek mythology, Nyx (Νύξ, Nox in Roman translation) was the primordial goddess of the night. A shadowy figure, Nyx stood at or near the beginning of creation, and was the mother of personified gods such as Hypnos (sleep) and Thánatos (death). Her appearances in mythology are sparse, but reveal her as a figure of exceptional power and beauty. She rules over an earth-based religion.

Nyx is Night.

Black winged Nyx, some say, laid a germless egg in the infinite bosom of Erebus, the Darkness of the Underworld, and after long ages, sprang golden-winged Eros. But others have said that Nyx is the daughter of Eros, whereas others called both of them children of Chaos. Nyx is Night, a powerful goddess whose dark light falls from the stars, and who dictates not only to men but also to gods. Even Zeus does not wish to upset Night: It happened that Hera bribed Hypnos in order to make Zeus fall asleep, so that she could have it her way during the Trojan War. Hypnos obeyed the goddess in spite of his fears; for once he had performed a similar task, and when Zeus woke up in anger, he sought him everywhere, and would have hurled him from heaven into the deep, had Nyx not saved him. For Zeus stopped and thought twice before doing anything that could displease Nyx. Some seem to think that Nyx appears because light is gone as if anything could be and yet do not exist on its own right.

In Tartarus, both a place and her brother, Nyx has her home and spreads around him in triple line like a necklace. At the gates of Tartarus and above it are the sources and ends of heaven, earth and sea, and it is told that if a man should find himself inside the gates, he would not reach the bottom for one year, being carried by blasts in all directions.

Night covers shame, spares lives.

Night restores what Day undid and destroys what Day did.

Night, they say, carries Hypnos in her arms, but if he refuses his comfort, the night-long vigils make the eyes of mortals sore. For in night-time most things and beings are restored so that they might enjoy or suffer the following day.So what is done by day is undone by night, which was known by Odysseus' wife Penelope, who wove by day the shroud of her father-in-law Laertes and undid it by night, thus deceiving her SUITORS, for she had promised to wed one of them when her work was finished.

Love, Death and Madness are best at night.Night is also a time of inspiration, and that is why it is told that the MUSES sing during night-time their praises to the gods and Nyx on Mount Helicon, and they themselves are the result of the nine nights that Zeus spent with Mnemosyne.
