Cal Zhorin was a human male Agent in the Galactic Empire, who defected to the Rebel Alliance. Born into a family of modest wealth on the planet Serenno, he pursued his dream of serving the Empire, attending and graduating from the Imperial Academy on Carida. Serving in Imperial Intelligence, Zhorin would perform various tasks, such as infiltrating rebel cells and spying on any possible threats. After the destruction of the Death Star, Zhorin was transferred to the Imperial Security Bureau and given the rank of Commander, where he monitored the internal affairs of the Empire.
