Ganuk was an Evocii male who worked as a foreman. He resided on Nar Shaddaa throughout the Cold War era, a period of conflict between the Galactic Republic and the newly reformed Sith Empire.
During the year 3643 BBY, Ganuk uncovered a plot by the Sith Empire involving toxic substances designed to kill the entire Evocii population of the planet. Following this discovery, he disseminated this information and then requested that a person allied with the Republic break into the Pharmalux Waste Processing facility to stop Commander Vergost from releasing these deadly chemicals, which threatened the lives of millions.
