Artagan Truax was a Human male inmate of the Cog Hive Seven prison by the year 33 BBY. Truax worked to protect his son and fellow prisoner, Eogan Truax, from the rest of the prison's general population.
Originally a member of the Bando Gora, a cult of Force-worshiping assassins operating in the Outer Rim Territories, Truax turned on the cult when he saved the life of arms dealer Iram Radique, one of its targets. Fearing the Bando Gora's retribution against himself and his son, Truax took refuge inside Cog Hive Seven, where Radique had established his base of operations.
