Kale Longo, known in the Imperial system as Inmate ICN 544450, was a prisoner onboard the Imperial prison barge Purge alongside his brother, Trig Longo. The barge broke down during its mission to transport a shipment of prisoners to a detention moon. Kale and his brother were two of six survivors on the Purge after a recon team contracted and spread a deadly disease from a nearby derelict Star Destroyer.
