Cheryl Farley

Cheryl Farley was a young woman who believed in astrology and was paying Martin Trueman to make predictions for her. Her husband Stuart thought that she was wasting their money. When Trueman was taken by the Ancient Lights, he used their power to take control of Cheryl's mind, making her his henchman. He made her give him all her money, leave her husband and become his assistant on his shows. Cheryl was later freed from Truman's control when Luke Smith stopped the Ancient Lights, Cheryl was freed from Truman's control and returned to Stuart.
