Etheria was a dabo girl in Quark's between 2372 and 2372.

She was among the employees of Quark's who went on strike because of a pay cut and lack of sick pay. Together with Rom, Leeta, Broik, Frool, and Grimp she tried to pay the customers on the Promenade for not visiting Quark's. (DS9: "Bar Association")

When Quark was questioned by Ch'Pok, a Klingon prosecutor during the trial of Worf on Deep Space 9, about what the Ferengi overheard about the attack conducted by Worf on a Klingon ship, Quark said that it was when Dr. Julian Bashir was talking to Etheria. However, Quark then believed it was another dabo girl. (DS9: "Rules of Engagement")
