Shynne was a Human female who was raised on the Deep Core planet Prakith during the reign of the Galactic Empire. Shynne studied the ways of the dark side of the Force as a member of the Inquisitorius, an order of Dark Jedi who served the Empire, and she resided in the Citadel Inquisitorius, the order's headquarters on Prakith. At some point, the Inquisitors captured a member of the New Jedi Order, and Shynne planned to help turn the Jedi to the dark side.
