Nemesis was the right hand of Zeus.

She was the Goddess of Righteous Anger

and it was she who saw to it that all good and evil were justly paid.

 She was also without a direct personality. She is also called Adrasteia, which means the Inevitable Parents. She was either another daughter of Oceanus, or a daughter of Nyx and Erebus (making her a sister to Sleep and Death).
