Dahna was a religious faith among Andorian civilization. Adherents of this faith had a profound certainty of their own rightness with its beliefs centering on the concept that the natural universe was a pure and unpolluted place, but the actions of sentient beings had polluted it. This somewhat bizarre logic focused that the universe should had remained lifeless and that the stars should had burned in pristine glory with the planets untroubled by the arrogant destructive semifungal growth that was life. It was the dominant faith at the Third Submission Colony in 2371. (TNG novel: Intellivore)
