Quark once thought to himself that Starfleet members were "dull, boring, root-beer-swilling slugs who wouldn't know a good time if M'Pella invited them up to her room for a nightcap". (DS9 novel: The Fall of Terok Nor)
In 2375, M'Pella and Leeta told Quark that they only wanted to give him ten percent of their tips, rather than twenty. When Quark thought he was about to be named Grand Nagus by Zek, he planned to take M'Pella with him to Ferenginar and give her her own room in the Nagal Residence. Quark soon learned that he was not to be the new Nagus and ordered M'Pella to rig the dabo table as part of his plan for Quark's to be "the last outpost" of the old Ferenginar. (DS9 episode: "The Dogs of War")
Following the the Destruction of Deep Space 9 in 2383, M'Pella returned to Bajor and worked at Quark's new establishment in Aljuli. She was working the dabo tables with Hetik when Julian Bashir and Sarina Douglas entered the bar. (Typhon Pact novel: Raise the Dawn)
M'Pella was identified as being Bajoran in The 34th Rule, although she never had the Bajoran ridges on her nose in the series itself. This is explained as a rare genetic mutation in the ST - Typhon Pact novel: Raise the Dawn. Why she never wore the Bajoran ear piece remains unexplained, however, although Bajorans like Ro Laren and Varani did not wear them.
