  Quotations
  The geth are a humanoid race of networked A.I.s. They were created by the quarians 300 years ago as tools of labor and war. When the geth showed signs of self-evolution, the quarians attempted to exterminate them. The geth won the resulting war. This example has led to legal, systematic repression of artificial intelligences in galactic society.
