This particular person was a bartender of the Muun species, identified as male, and he served drinks in a cantina located within the city of Pilaan on the planet called Muunilinst.
During the year 0 ABY, Han Solo and his companions successfully extracted details about the disappearance of Mak Luunim, a Rebel Alliance contact, from this bartender. The bartender suspected that Luunim's recent death was not an accident, but rather orchestrated by Nal Kenuun, a Muun gambler to whom Luunim was in debt for credits. When further questioned about Luunim, the bartender abruptly ceased speaking and withdrew into the cantina's rear area to begin washing dishes.
