A female operative of the Imperial forces, whose gender was female, impersonated Chilla. The real Chilla was a clandestine agent working for the Alliance to Restore the Republic, but her true identity had been exposed.
Shortly after the Battle of Yavin, an operative of the Alliance to Restore the Republic, known as Chilla, served as a bartender at The Rusty Bucket. This establishment was a bar situated in the city of Takari, located on the planet Iyuta. The Empire uncovered Chilla's true allegiance, and after being wounded, she sought refuge within the ancient sewers of the planet, where she ultimately died.
As part of a scheme to find the Rebel base within that sector, the Empire substituted Chilla with a female impersonator. This fake Chilla was employed at The Giant Step, and was approached by Green squad from Reekeene's Roughnecks when they received orders to monitor a recently constructed Imperial Communications Center. To uphold her disguise, she aided them in their assignment. However, Green squad stumbled upon the deceased body of the genuine Chilla, thereby thwarting the impersonator's intentions.
