Tavion is the Dark Jedi apprentice of Desann, and appears in Jedi Outcast and Jedi Academy of the Star Wars: Jedi Knight series. In Jedi Outcast, Tavion first appears when Kyle encounters Desann during a battle between the Rebels and Imperial troops on Artus Prime in the Outer Rim Territories. Kyle finds that Tavion has captured Jan Ors, Kyle's mission partner and secret love. At the time, Kyle had already given up his lightsaber and his will to use the Force. As a result, Desann easily defeated Kyle, and he and Tavion pretended to kill Jan. They left Kyle, who was in grief and despair thinking he had lost Jan.
After Kyle began to regain his Force powers in search of the Valley of the Jedi, he found Tavion at Cloud City on Bespin. She taunted him, saying that she had killed Jan only to lead Kyle to the Valley of the Jedi, which was Desann's real plot to start a new force of warriors called the Reborn. Kyle and Tavion duelled intensely, and once Tavion realized she was no match for Kyle's superior fighting skills, she begged for mercy, and finally admitted that she faked Jan's death. Kyle left Tavion in search of Desann. Tavion fled, and afterwards Kyle had killed Desann at Yavin.
In Jedi Academy, Tavion is the primary antagonist of the game. Tavion stole the Scepter of Ragnos, a powerful dark side artifact containing enormous amounts of Force energy. It could be used to blast energy against the enemy. Inside the scepter was the sword of Ragnos. Jedi Knight Jaden Korr came to stop her, and Tavion used the scepter and her own lightsaber to defend herself. When Tavion realized she could not defeat the Jedi, she caused the Force ghost of Marka Raknos to come out of the large statue in the room. The ghost overtook Tavion's body, and used his long-lost sword inside the powerful scepter to try and hold back the Jedi. When he failed, Tavion could not withstand the corruption of the ghost, and she died. Ragnos then was imprisoned in his tomb again, but not dead.
However, in the dark side alternate ending of Jedi Academy, Jaden kills Tavion with no mercy and just takes the scepter to have it and it's power for himself, but he doen't unfortunatly ressurect Ragnos with it, he just flees with it after defeating his former master, Kyle Katarn in a lightsaber duel and killing Rosh.
