Nemesis

Nemesis (Νεμεσις), also known as Adrasteia (Αδραστεια) or Rhamnusia (Ραμνουσια), was the Greek goddess of retribution and balance. She secured balance by punishing those who committed evil deeds and those who were given undeserved good fortune. Nemesis was typically depicted with an attribute, such as an apple branch, a rein, a lash, a sword, a goose, or a balance. She was a daughter of Nyx.

In Roman mythology, she was sometimes known as Rivalitas.
