Salahi, identified as male, held positions as both a professor and the chief scientist within the Galactic Republic's Special Weapons Group throughout the Clone Wars. This Special Weapons Group had the responsibility of developing a large superweapon for the Republic, specifically a mobile battle station that would eventually become the Death Star. As the Clone Wars concluded, the Republic underwent a transformation to become the Galactic Empire, but the battle station initiative persisted under the name Project Celestial Power. In the initial period of the Empire's reign, Sahali could be found on the planets of Malpaz and Hypori, collaborating with fellow Celestial Power scientists to advance the development of the battle station's weaponry.
