Ona Querit

Ona Querit was a Human Female arms dealer who lived during the time of the Galactic War between the Galactic Republic and the resurgent Sith Empire. She was the daughter of Senator Querit until Kaliyo Djannis seduced her to leave Coruscant to live a life of adventure among the galaxy's criminal elements. Kaliyo left her in Elysium. Eventually she made her way to Alderaan where she learned to duel. She became the Bounty hunter known as the "Menace" and has been hunting Kaliyo not only for her reward but to also show her how strong she's become. Kaliyo only knew the Menace was after her so she made the bounty hunter a target of Imperial Intelligence.

Cipher 9 and Kaliyo tracked her down and assassinated her.

Behind the scenes
If the agent player chooses a light side option, he/she can avoid violence by persuading Ona to abandon her quest for vengeance and let Kaliyo go.
