Adrasteia

Necessity. Adrasteia existed with Chronus (Time) at the beginning, before the world was created. Another name for the personification of “Fate” or “Necessity” is Ananke.

Like Chronus, Adrasteia was portrayed as giant serpent or dragon, but as a female principle of Necessity, just as Chronus was a male principle of infinite Time. Adrasteia was the mother of Chaos, Erebus and Aether.
