Nyx, Goddess of the Night portrait

Nyx is one of the Primordial gods and goddesses, known to the Greeks as the Protogenoi - the “firstborn.” The primordials are the basic elemental fabrics of the universe, created at the beginning of existence.

Nyx is the Primordial goddess of the night; a dark, powerful and mysterious being, mother of many dark deities and feared by both men and gods alike - so powerful that even Zeus King of the Gods himself would not dare incur her wrath.

Despite her dark nature and unfathomable power, she is not evil, but nor is she good - she is simply indifferent, and has grand tasks to complete. She rarely concerns herself with the actions of mortals, or even other gods.
