Dawn was was VIcenzo's assistant in his magic acts. When he started experimenting with the shadow realm, he did one of his tricks to make her disappear (into the shadows). But couldn't bring her back, he then figured out a way to do the same to himself and to travel between the shadow world and the real world just as Dawn did. Dawn is a young woman of indeterminate age. Living in the shadows, she can pass for one of them, moving between reality and shadow worlds.
