In 2370, she traveled to DS9 in hopes of purchasing a locale on the Promenade. When she realized no space was available she turned to Quark in hopes of purchasing Quark's. She tried using her charms to bring the Ferengi to sell. When Quark made it clear that he was not interested she turned to death threats. It was later discovered that this was part of a larger design by the Romulans to instigate war between the Klingon Empire and the Cardassian Union.
Maura was a skilled hand-to-hand combatant. Skills she used to defend Quark when two Cardassians tried to extort latinum from him. Maura was romantically involved with the captain of the Arvas, Delgar.
After escaping she headed straight to Quark's, once on the promenade she shot a Starfleet officer. Once in the bar she took the barkeep as an hostage and fleed to the nearest docking bay. She was eventually tracked down by Kira who rendered her unconscious. According to Kira she was to be sentenced to about 50 years at the Tantalus Penal Colony.
