Manda D'ulin served as the commander of the six female warriors known as the Mistryl Shadow Guard.
In the year 0 BBY, she received communication from a scientist named Kellering. He stated he sought extra protection for the Hammertong endeavor, acting on behalf of Dr. Eloy.
Nevertheless, during her journey with Kellering to the facility to encounter Eloy, Imperial forces ambushed her and fatally shot her. Shortly thereafter, her fellow guard Pav D'armon suffered the same fate. In response, the remaining Mistryl members launched an assault on the base, seizing the Strike Cruiser that housed the Hammertong prototype.
