The Brentaali constituted a specific social circle. In a report dispatched to Admiral Gial Ackbar before the Battle of Endor, Lando Calrissian drew a comparison between the potential weapon setups for the YT-series and a list held by a Brentaali sommelier, while discussing vessels that could fulfill the Alliance's requirements.
Daniel Wallace's 2017 reference book, Star Wars: The Rebel Files, marked the initial mention of the Brentaali.
