The Grave Tuskens were a mercenary swoop gang comprising Tusken Raiders. Originally, the Dark Jedi Maw used the Grave Tuskens as a personal strike force.No one knows how Maw gained the services of the Grave Tuskens. What is known is that they were taken from their home on Tatooine and trained to be Maw's personal strike force. They were only a few hundred in number and strangely, they were trained in the use of modified (so as to be easier to use for weaker beings) Wookiee bowcasters. Maw used them to plunder artifacts from the tombs of both light and dark Jedi, which was how they earned their grisly name.
