The Dusk Shadow, a Terentatek, roamed the Dune Sea of Tatooine.
In the era of the Cold War, Qyzen Fess's feelings of disgrace over failing to gain points on Tython prompted the Barsen'thor to journey to the Dune Sea, as requested by Qyzen; the Trandoshan sought to atone to the Scorekeeper by honoring his father's remains on Tatooine.
Having located and paid tribute to the bones, they were approached by a Trandoshan hunter who informed them that the Dusk Shadow had been preying on the local farmers' Banthas and that he was attempting to eliminate it with explosives, inadvertently placing them in the middle of his minefield. Following their disagreement, the Dusk Shadow emerged, causing Lek to flee and the Jedi and Qyzen to confront it. Together, they brought about its demise.
