"Sir, we've been instructed to bring you down to the infirmary."
―Saltern, to Jareth Sartoris[src]

Saltern was a male individual who served the Galactic Empire as a guard aboard the Imperial prison barge Purge. In 1 BBY, the Purge broke down while undertaking a voyage to the detainment moon Gradient Seven, and several crew members from the ship boarded a nearby derelict Star Destroyer to look for spare parts. However, the boarding party were exposed to the deadly blackwing virus while on the ship and, after they returned to the Purge, several of them died from the infection. Saltern and another guard donned bio-suits and were sent to escort Captain of the Guard Jareth Sartoris—the leader of the boarding part—to the barge's infirmary, to put him into quarantine.
