Mayor Story Arcs

Professional Assassin

Amy soon made a reputation for herself. She was known for killing several men on different occasions. This brought her to the attention of a local guild of assassins. She was recruited and trained to become a professional assassin. She rose to become one of the most skilled assassins active in Southeast Asia (Brunei, Cambodia, East Timor, Indonesia, Laos, Malaysia, Myanmar, Papua New Guinea, the Philippines, Singapore, Thailand and Vietnam). She also gained a reputation for her unique way of expressing dissatisfaction with any given employer or guild leader. Killing them and then moving on elsewhere. 

Foreigner

She eventually joined the 1400 Club, the guild led by the Foreigner. She respected the man enough to not kill him. But left the Club along with  four other female assassins (Maria, Roberta, Sheila, and Sophia). They formed their own guild. Amy had the most independence ever allowed to her. She enjoyed it for a few years before taking a job offer from Silver Sable and becoming a mercenary. 
 
Amy Chen was strongly hinted to be a lesbian. Her fierce loyalty to Sable and tendency to call her  “M’lady”, an expression Amy also used for former lovers, implied that her main love interest was her boss. Which did not prevent her from open admiration of Lightbright.
