Grun was a human male that worked as one of the core members and workers at Chalum's Catina in Mos Eisley.
For some time, Grun and his twin brother, Grin, have been working together with the Wookiee Chalum and Wuher to create Chalum's Cantina on the desert planet of Tatooine. In 0 BBY, he was working in the cantina alongside Wuher when the forces of the Galactic Empire arrived in the town of Mos Eisley in search of the missing Death Star plans. Since the cantina previously allowed a pair of individuals who had the plans into their establishment, the Empire decided to briefly close the cantina and assigned Shock Trooper, Teflin McBomb, to interrogate Grun. This ended up backfiring for the Empire, as Teflin ended up accidentally blowing Grun up with his rocket launcher.
