Grand Chieftain was the title that the Flesh Raider Keshk held as leader of his species on the planet Tython. During the Flesh Raider uprising in 3643 BBY, Keshk commanded the Flesh Raider army and performed the bidding of his master, the Dark Jedi Bengel Morr. After Keshk's death and Morr's defeat, the army dissolved, and it is unknown whether any attempted to take his place as Grand Chieftain.
