On a mission to the remnants of the Deep Core planet Byss, which had been obliterated by the Galaxy Gun in 9 ABY Rosh would attempt to learn of the possible presence of Ragnos Disciples, he was captured by Tavion Axmis, who was previously draining the Force energy from Byss. He was then made a Dark Jedi for a short time, leading the Cult to Vader's abandoned castle on Vjun to drain its Force energy. It would be then that he'd confront Jaden Korr, his once-time ally, and duel him in a battle which ended in his defeat, only to be later taken away by Tavion. Original SW Canon ends here.
