Nedecca, a Human female major, held a position in the Imperial Military of the reconstituted Sith Empire during the Galactic War against the Galactic Republic. Sometime around 3642 BBY, she was a subordinate to Darth Gravus during the invasion of Taris; their partnership persisted when she joined him and his troops on Rabaan. By approximately 3640 BBY, she received orders to go to Corellia and serve under Sith Lord Razer. She fought in the Battle of Corellia, taking part in attacks like the one on the Aegis Base alongside Major Sanos and the ex-Intelligence Agent Cipher Nine.
