Who is the primordial goddess of night?

The story behind the answer

Nyx is the primordial goddess of night in Greek mythology—one of the first beings (Protogenoi) born from Chaos. She personifies the very fabric of night itself, so powerful that even Zeus is said to have feared angering her. As a mother of many abstract deities—like Hypnos (Sleep), Thanatos (Death), the Fates, and Nemesis—Nyx embodies the deep, mysterious forces that emerge with darkness.

To avoid confusion: Erebus is primordial darkness (the shadowy gloom), Selene is the moon goddess, and Hecate is associated with magic, crossroads, and witchcraft—not the origin of night. Memory tip: Nyx sounds like “nix” or “nox,” echoing the word for night in several languages (Latin nox, German Nacht), and the N in Nyx can stand for Night.
