The Last of the Jedi Masters
Before they could confront the Emperor, Vader tells Galen that he must defeat someone more powerful than the other Jedi, Shaak Ti. On Felucia, she is training an army of Felucian Force-users. When she spots the Rogue Shadow, she tells her Zabrak Padawan Maris Brood to hide while she lures the assassin to the place of sacrifice, the mega sarlacc's nest. But even her strength and communion with the sarlacc are no match for Galen. Before she dies, Shaak Ti warns him that the Sith always betray one another.
