Adrestia in Greek mythology 'she who cannot be escaped' was the daughter of Ares and Aphrodite and known to accompany her father Ares to war. She was venerated as a goddess of revolt, just retribution and sublime balance between good and evil. Because of her role in revenge and retribution, she was usually portrayed with Nemesis, and sometimes identical to Nemesis herself, who had the epithet of Adrestia or Adrasteia. She was also believed to be another war figure, similar to her brothers Phobos and Deimos.
The union between Ares and Aphrodite produced many children: Eros (the god of love), Anteros (the god of requited love), Phobos (the god of fear), Deimos (the god of terror), Harmonia (the goddess of harmony and concord), and Nemesis, besides Adrestia herself.
