Tech Sergeant Hooly, a male character, functioned as a training instructor within the Rebel Alliance Military throughout the Galactic Civil War. His expertise lay in the handling of blasters, and he held the responsibility of educating Cee Norley. Norley would later reflect on Hooly's lessons while on the planet [Dorlo], during her confrontation with the Galactic Empire's forces. Following her destruction of an Imperial skimmer, Norley commented that Hooly would have approved of her actions. Tragically, Hooly's trainee was soon killed by an Imperial Dark Jedi.
