Corbin, employed as a miner, worked within an underground mining colony located on an airless moon situated in the Outer Rim Territories. This individual harbored feelings of envy towards some of his fellow workers, notably Fiona and Ryland. In the year 2 BBY, following the Galactic Empire's consolidation of power over the colony, Corbin orchestrated a scheme to falsely accuse Fiona and Ryland of being rebel spies, which ultimately led to the death of Fiona.
