Logar

Logar was a fire god worshipped by Timanov and most of the Trions inhabiting Sarn. Amyand and Roskal climbed the volcano and found that Logar was not there, and the Fifth Doctor discovered evidence that the god was based on memories of Trion vulcanologists in thermic suits. Despite this, Timanov remained devout in his faith. (DW: Planet of Fire)
