Amber's ability is chronal manipulation, which includes temporal freezing of time and rewinding of events to an unknown degree. Elaborate usage of her power enables her to gain knowledge of future events, and then respond to them accordingly. Once time has been frozen around her, she can also pull other people out of the frozen time stream, while those still under her ability's effect will no longer detect her presence or movement. Her remuneration is aging backwards, making her appear frequently younger. Amber loves Hei, in spite of him believing her to be a traitor, and has stated that she has only seen him truly smile once and she would do anything to see that smile again. Amber's feelings for Hei often result in her making decisions that compromise the mission objectives of the Evening Primrose and at times she goes as far as to order her subordinates to avoid fighting Hei.
