Zaz Kamiroz was a male Human miner who belonged to the Alliance to Restore the Republic. He and Hanos Darr were stationed at Mining Outpost 11, a mining operation located in the Graveyard of the Alderaan system, where they were tasked with finding valuable ores. The Galactic Empire, seeking to ensnare the Heroes of Yavin in a trap near the remnants of Alderaan, disseminated false information to the miners, claiming that the Aldera Royal Palace had been discovered within the debris field. As part of their effort, the miners were then instructed to evacuate the facility. Kamiroz and Darr journeyed to the Ithorian Herdship Bazaar, where they used a prearranged code with Poliss, an Ithorian Alliance operative, to arrange a meeting with Princess Leia Organa. Poliss successfully concealed Kamiroz within the ship's Dome of the Mother Jungle; however, Darr met his death at the hands of XS3, an assassin droid deployed by the Empire. Kamiroz himself was attacked by another assassin, Ferreges, a Human female, but was saved by an Alliance team who happened upon the scene. Before being sent to receive medical attention for his injuries, Kamiroz shared the information he possessed with the team, mistakenly believing them to be the Heroes of Yavin.
