The Tripods' homeworld is located in an area governed by the Galactic Empire. Some of them were among the aliens taken prisoner aboard the giant warship called the Eye of Palpatine, where they were able to resist brainwashing. Their needs were later taken care of by the gentle Talz. A rather primitive race and not properly integrated in the galactic community yet, the Tripods refer to themselves simply as "the people", and to their homeworld simply as "the world".
