Galatean

The Galateans were a race of robots.

History
At an unknown point in time the Galateans were at war with the human race. The Galateans and humans both worshipped Chiyoko as a god. Neither side knew that the war had been started by Chiyoko. Near the end of the war before the destruction of Earth, Chiyoko decided that the Galateans were superior and that the humans would have to 'go away'.

10 million years later the Galateans had destroyed every other species in the universe. All that remained were robot humans in the Museum of Lost Opportunities. (DWM: The Child of Time)
