A Brekkian woman travelling with a cargo of felicium aboard the freighter Sanction in Symbiosis, who knows that her people's trade depends on keeping the Ornarans addicted.
Langor is a Brekkian who appears in the first-season episode Symbiosis, set in 2364. She and her colleague Sobi are rescued from the failing Ornaran freighter Sanction together with two Ornarans and a single container of felicium.
Brekka's whole economy rests on producing felicium, which the Ornarans believe is the only treatment for a plague. Langor and Sobi argue coolly that the cargo is still theirs because payment was lost with the ship, and then offer it as a gesture of generosity.
Beverly Crusher works out that the plague was cured long ago and that felicium is simply a narcotic. Langor privately admits to Picard that the Brekkians know this. He cannot expose them under the Prime Directive, but declines to repair the Ornaran freighters.
