I-M3 was the designation of a battle droid of the Sith Empire deployed on Balmorra during the Galactic War. The droid was destroyed in combat, but it remains were scavenged by the Galactic Republic technicians. Despite being dismembered, the neural processor of the droid was still functional. While technicians continued to work on it, the droid assumed it was still in Imperial hands and relayed to a Republic citizen its last mission - to recover Shadow Squadron transponders from the their crash sites.
