The Platonians or Plato's Children were a humanoid species native to the planet Sahndara who patterned their lives after the teachings of ancient Greek philosophers Socrates and Plato. In the 1st millennium BC, they were the product of a mass eugenics program on the planet Sahndara. They were bred for contemplation, self-reliance, and longevity. The number of individuals generated by the program was pared down to thirty-eight. Before the planet's star went nova, this group resettled on Earth where they were exposed to the Greek civilization. When this civilization died, they moved on to Platonius where they founded their republic.
