Nyx

Nyx was the goddess of the night, one of the primordial gods who emerged as the dawn of creation.

She was a child of Chaos (Air), and coupling with Erebos (Darkness) she produced Aether (Light) and Hemera (Day). Alone she spawned a brood of dark spirits including the three Fates, Sleep, Death, Strife and Pain.

Nyx was an ancient deity usually envisaged as the very substance of the night--a veil of dark mists drawn across the sky to obscure the light of Aether, the shining blue of the heavens. Her opposite number was Hemera (Day) who scattered the mists of night at dawn.

In ancient art Nyx was depicted as a either a winged goddess or charioteer, sometimes crowned with an aureole of dark mists.
