Mystra

Mystra was an alien assassin who served as an enforcer for Raskar, a former pirate and the ruler of the planet Antipose. Raskar organized profitable gladiatorial competitions with a rare power gem as their ultimate prize, and Mystra helped him maintain order on the planet, which included killing undesirable individuals on her employer's behalf.

In 0 ABY, when the smugglers Han Solo and Chewbacca arrived on Antipose in search of a power gem, Mystra interrupted a confrontation they had found themselves in with a trio of competitors for the artifact. The enforcer took the pair to meet Raskar, who demonstrated the power gem to Solo and attempted to persuade the smuggler to participate in the arena fighting for it. Suspecting that Solo would attempt to find a way to obtain the gem outside the system, Mystra then tried to intimidate the smuggler with her skill with a wrist blaster.

Nevertheless, Solo eventually had Chewbacca start an impromptu brawl, observed by Mystra from afar, with the leading gladiator in order to create a distraction that allowed him to sneak into Raskar's villa and perform a close scan of the power gem. Determining that the artifact's useful properties had diminished over time—a fact that Raskar had not disclosed to any of the contestants competing for it—Solo ultimately convinced the ex-pirate to let him and Chewbacca leave with the gem, and Raskar and Mystra both saw the smugglers off as they departed the planet.
