Atoan, the language used by the indigenous population of the world Atoa, presented a communication barrier to Imperial troops upon their arrival circa 19 BBY. The natives' lack of fluency in Basic was considered unusual, particularly given the long-standing involvement of the neighboring planet Umbara with the Galactic Republic.
However, a notable exception existed in the form of Lady [Saro], a shaman who claimed to have acquired Basic proficiency after an encounter involving the demise of a stormtrooper and the subsequent consumption of the trooper's tongue.
