Knox was a male Nautolan Jedi Padawan living during the Clone Wars between the Galactic Republic and the Confederacy of Independent Systems. Alongside with his master, the Roonan Halsey participated in the Republic's defense of the Temple of Eedit on the planet Devaron. Though the Jedi and their ARF troopers were initially successful in fighting off the Separatist battle droids, the Zabrak Savage Opress, a pupil of Separatist leader Count Dooku, turned the tide of the battle and cut through the Republic defenders. Both Knox and his master were killed by the Zabrak assassin. The Jedi's bodies were later recovered and transported to the Jedi Temple on the planet Coruscant by the Delta Squad.
