Hartla was a dabo girl who worked at Quark's on Terok Nor during the Cardassian Occupation of Bajor, and was still working there as of 2370 when it became Deep Space 9. One of her special clients was a Cardassian officer named Boheeka.
When Quark contacted Boheeka about a clandestine deal he wished to make, Boheeka reminisced about Hartla, missing her but observing that she would have bankrupted him had the Occupation lasted longer. (DS9 episode: "The Wire")
