Nyx is the goddess of Night, A shadowy figure, Nyx stood at or near the beginning of creation and mothered other personified deities, such as Hypno's(God of Sleep), and Thanatos(God of Death), and Erebus(God of Darkness). In Hesiod's Theogony, Nyx is born of Chaos. With Erebus, Nyx gives birth to Aether( God of Brightness) and Hemera(God of Day). Later, on her own, Nyx gives birth to Moros(God of Doom and Destiny).
In Greece, Nyx was only rarely the focus of cults. According to Pausanias she had an oracle on the acropolis at Megara. More often, Nyx lurked in the background of other cults. Thus there was a statue called "Nyx" in the Temple of Artemis at Ephesus.
Nyx took on an even more important role in several fragmentary poems attributed to Orpheus. In them, Nyx, rather than chaos, is the first principle from which all creation emerges.
