Halcyon Vengeance is a young woman with short black hair. Her build is petite, athletic, and androgynous. She wears inexpensive, comfortable, dark colored clothes which don't attract attention. Her manner is quiet but intense and she exudes likability. Her gaze is steady and piercing, but she seems to be aware of more than just what she is looking at. Her silver tattoos are concealed as is her tell, most of the time. When her tell is visible, her thumb and the two middle fingers of each hand are greatly elongated.
