Employed by Republic Intelligence during the Clone Wars, she operated out of Tarhassan following the First Battle of Geonosis. A former member of the Department of Health, she was part of a specialized team to rescue Edbit Teeks from prison. Along with Mapper Gann, Joram Kithe, Livintius Sazet, and Cherek Tuhm, they kidnapped a Separatist agent named Zazana Renkel who knew about Edbit's location. After receiving the intel, Tinian disguised herself as a guard and assisted in transferring a prisoner to the Nehass prison. During that phase of the operation, Kithe proudly welcomed her into intelligence service.
