Innamin, a human individual, was an engineer by trade who achieved the military_rank of Petty Officer, and subsequently Chief, within the Republic Defense Coalition. Functioning as a Petty Officer under the command of Captain Finial Bright on the Republic Longbeam cruiser named Aurora IX, he frequently challenged directives, a behavior that Bright generally tolerated. In a joint operation with the Jedi Order aimed at safeguarding the Hetzal system from hyperspace anomalies, Innamin discharged missiles from the Aurora IX toward one of these anomalies in an attempt to shield a solar array; however, the projectiles missed their mark due to the anomaly's high velocity. While rescuing the Array's personnel, Innamin dedicated his efforts to maintaining the stability of the station's dangerously overheating reactor. Upon determining that the reactor's stability could not be sustained long enough for a full evacuation, he offered to remain behind. Nevertheless, his captain, Fenial Bright, countermanded this offer, instructing him to evacuate and choosing to sacrifice himself. Following this incident, Innamin received a promotion to the rank of chief.
