Nanz was a bartender at Oga's Cantina in Black Spire Outpost on Batuu. She was a human woman who was older than the Resistance spy Vi Moradi. The spy's impression of Nanz was of someone grouchy who had forgotten how to smile; she was therefore surprised when Zade Kalliday flirted with the older woman and she returned his attentions. As Kalliday worked up a crowd with condemnations of the First Order, she warned him to stop because Officer Wulfgar Kath was in town with his stormtroopers.
When Moradi first saw her, Nanz was wearing faded blue and mustard yellow robes. Later, Nanz acquired and wore one of Moradi's stolen wigs.
