A pre-industrial Delta Quadrant people whose prophecy of Great Sages arriving from the sky was exploited for seven years by two stranded Ferengi in False Profits.
The Takarians appear in the Voyager episode False Profits. They are a humanoid society at roughly a Bronze Age level, whose epic poem, the Song of the Sages, foretells that holy beings will descend in fire to rule them.
The Ferengi Arridor and Kol, lost on the far side of the Barzan wormhole since the Next Generation episode The Price, crash on the planet and are taken for the Sages. They install a replicator in the temple, rewrite local morals along the lines of the Rules of Acquisition and grow rich while the population sinks into poverty.
In 2373 Voyager finds the wormhole's unstable end nearby. Janeway cannot simply remove the pair without shattering Takarian belief, so Neelix poses as the Grand Proxy and the crew stage the prophecy's ending, in which the Sages depart in flame.
