In 17 ABY, a Dark Jedi thief named Portoris Bol stole a cache of Sith artifacts and books from Dran Festow, a reclusive collector who lived on Umbara. Bol set out for Kothlis, unaware that he was a pawn in a much larger plan. 'Festow' did not exist as such; the cache was only partly genuine; his buyer didn't exist either; and he'd been manipulated into the theft in the first place. The whole setup was arranged by Velok and Ald Sorosel, who placed a detailed bounty for the return of the cache in hopes that Darksiders would come out of the woodwork and chase Bol across the galaxy. In the meantime, they could evaluate those Darksiders, and eliminate the ones they chose while recruiting others.
