Lieutenant Heskon was the chief security officer at the Gammak Base in the Uncharted Territories. When John Crichton arrived at the base under the guise of Captain Larraq with his "companion" Chiana, Heskon greeted them with the base's commander, Javio. Like his commander, Heskon took a liking to Chiana. As security chief, Heskon's duties included verifying the identities of all visitors. This became a problem for Crichton when Heskon subjected him to a genetic scan. He managed to pass it, however, thanks to the efforts of one of the base's techs, Gilina Renaez.
