Ralchio Nervi, born Ralchio Sargan, was a human male who served in the navy of the Galactic Empire. The son of Vilola Sargan and Jans Coorsa of a clan of Confederacy of Independent Systems sympathizers on Gall, Nervi was Force-sensitive. After unintentionally killing Coorsa in a fit of rage, Sargan fled, marrying Lila Nervi and joining the Empire. Nervi served as a lieutenant in the 14th Sector Fleet, where he gained the attention of Grand Moff Ravik. Due to his connections, Nervi was promoted to the rank of captain and placed in command of his own task force.
