Nexia Kirill, daughter of the infamous pirate Harridax Kirill (also known as "the Voidwolf"), was a Human female who became consumed by vengeance. Her father, who had risen to the rank of Grand Admiral within the reconstituted Sith Empire, met his end during the Battle of Corellia in 3640 BBY at the hands of a smuggler employed by the Galactic Republic; Nexia vowed to avenge him by finding and eliminating his killer, no matter the cost.
Nexia Kirill's appearance is limited to "The Nathema Conspiracy" flashpoint, and is contingent upon the Commander being a smuggler who opted for the Light Side path, choosing to dedicate Voidwolf's pirate fleet to the Republic as their class story concluded. Should this occur, Nexia Kirill will seek retribution against them, aligning herself with the Order of Zildrog under the leadership of Vinn Atrius. Ultimately, she is sacrificed on Nathema by GEMINI 16 to fuel the awakening of Zildrog. Conversely, if the smuggler embraces the Dark Side and retains control of the fleet, Jedi Master Sumalee will take Nexia Kirill's place, while the other classes encounter adversaries specific to their individual narratives.
