The people of Sarn descended from a high-technology society into tribalism and superstition. They worshiped Logar, God of the Fire Mountain, and sacrificed unbelievers in fire. In truth, Logar was essentially a Trion wearing a protective suit to protect them from volcanic activity. The descendants of the political prisoners had forgotten the higher technology of their ancestors.
When Turlough and the Fifth Doctor went to Sarn, Turlough sent a distress call to Trion, requesting assistance for the people, who were threatened by a volcanic eruption during the Time of Fire. (TV: Planet of Fire)
