Altair is the home planet to a race known as the Altairans. However, eventually the Altairans started leaving one by one, leaving Harlan, a lone android, who wants to carry on the tradition of his people on his own. The planet was subject to a form of radiation which destroyed the planet making it uninhabitable. Deep below the planets surface is a maintenance facility, built to keep the survivors alive. As the people began to die, they created artificial android bodies, and transferred their consciousness and memories into them. Thus saving the race.
