A female Human named Shynne, who embraced the dark side of the Force, was born and raised on the Deep Core planet of Prakith during the Galactic Empire's dominance. As a member of the Inquisitorius, an order of Dark Jedi in service to the Empire, Shynne dedicated herself to the study of the dark side's ways, making her home in the Citadel Inquisitorius, the order's headquarters located on Prakith. The Inquisitors once apprehended a member belonging to the New Jedi Order, and Shynne devised a plan to corrupt the captured Jedi to the dark side.
During the era of the Galactic Empire, there lived a Force-sensitive Human female named Shynne. She was raised by the Inquisitorius, an order of Dark Jedi loyal to the Empire, within the walls of the Citadel Inquisitorius—the order's central base—which stood on the Deep Core planet of Prakith. The Inquisitorius instructed her in the ways of the dark side of the Force, and she constructed her own lightsaber. Eventually, Shynne ascended to the rank of a full Inquisitor, choosing to operate primarily within the Deep Core region to remain in close proximity to the Citadel.
Following the death of the Imperial leader, Emperor Palpatine, and the formation of the New Republic in 4 ABY, the Empire began to fracture and was progressively overthrown. Shynne, along with the remaining members of the Inquisitorius, continued to reside within the Citadel Inquisitorius. At one juncture, the Inquisitors managed to capture a Jedi from the New Jedi Order who had journeyed to Prakith on a reconnaissance mission. As a rescue team was dispatched to Prakith with the aim of liberating the Jedi, the Inquisitors initiated the gradual corruption of the Jedi towards the dark side. Upon the arrival of the rescuers, Shynne greeted them, harboring a plan to compel the captured Jedi to confront the rescue party, hoping that this final act would irrevocably plunge the Jedi into the dark side's grasp.
Shynne, a stern figure, was among the most devoted members of the Inquisitorius. She was known for her cruelty and effectiveness as an Inquisitor, and she had a penchant for turning allies against each other to demoralize and break enemies of the Empire. She possessed dark features, a sharp, angular face, and typically wore robes.
Shynne was highly skilled in lightsaber combat and possessed a strong connection to the dark side, which she used to sense potential traitors to the Empire across the galaxy. She was proficient in using the Force to influence the thoughts of others, heal her own injuries, move objects with her mind, and enhance her speed. Furthermore, she had received training in the use of various powers including Battlemind, tutaminis, Drain Knowledge, Force empathy, Force stealth, and telepathy.
Rodney Thompson conceived the character of Shynne, who was first introduced in Byss and the Deep Core, Part 3: Prakith, an article published on Wizards.com in 2005.
