When a group of Rebels came to the planet Dandrian looking for Admiral Joser, they soon discovered that the only person who knew his location was Groon. The group managed to learn the directions to Groon's formex residence from an Imperial Gamorrean informant whom they captured after a swoop chase. When they arrived, Groon was sitting atop a pile of cushions in the back of a large, sparesely furnished room. He informed them that he was more than happy to tell them where Joser was being kept if they handed him 5,000 credits; after all, this was his job.
