The Dorandans were a race of humans on the planet of Doranda, and lived there ten thousand years ago. They were allied with the Lanteans, and let them build an outpost on their planet, where the Lanteans would begin work on Project Arcturus. Unfortunately, their experiment went out of control, killing everyone on the planet. (ATL: "Trinity")
