Destiny Sanderson

Destiny Sanderson is the mother of Emily Sanderson. Her husband left her when Emily was just five-years old, after which Destiny began to drink heavily and become desperate for a husband. She married another man, who also drank heavily, and began to verbally abuse Emily.

Because Emily's mother has the name "Destiny," Void suggests that the Faerie, working at Shadye's behest, purposefully "misinterpreted" his commands, and hence obtained for him the literal "child of Destiny."
