NEMESIS:
Nemesis was the Greek Goddess of vengence who punished those who had broken the moral code. She was the daughter of Erebus and Nyx.
It was her role to encourage moderation in society. In doing so she tried to eliminate arrogance. She appears in Hesiod's Theogony as the daughter of Nyx, the goddess of night (who also is the mother of the Fates). Her father is said to be Oceanus. Nemesis was as beautiful as Aphrodite and attracted the unwanted attention of Zeus, the king of the gods. A shape-shifter, able to fly over land and sea, she was attended by the goddess of punishment, Poena. Most often, Nemesis punished those who were too proud or who refused to acknowledge the blessings given to them by the gods or too selfish to share their good fortune with others.
