The guardians each had a favorite, though they were supposed to be impartial. For Jack had Jamie, and Bunny had Sophie, Tooth had Baby Tooth, North had Phil, and Sandy had a girl from America, though the others knew nothing of her.

He had found her when she was young, a girl just starting to learn to read. Her dreams were strong and had a tendency to overwhelm her true memories. He was worried for the child, who had difficulty distinguishing dreams from reality, so he watched over her every night. As she grew, he realized her dreams were getting stronger.

Determined to understand why this child's belief grew stronger with age rather than waning, he started to watch her in the daytime. He noticed an almost constant presence of his dream sand stayed with her throughout the day. He soon discovered her power as a daydreamer. The girl emerged herself in the worlds of books and movies daily and nurtured her imagination to its fullest extent. Her name was Aisling.

She shared this while playing with her siblings, but Sandy saw in her a potential that he hadn't seen for centuries. As she grew older, she inevitably discovered her parents were the ones that staged Christmas and Easter and he despised the disappointment that crushed her heart. Strangely enough, the light that shone on the globe for her didn't go out, but just dimmed until it was barely noticeable. He checked in on her less in the years after to not draw attention to her.

As Aisling started middle school, he saw she would often leave reality for the world of her dreams during classes, though her grades were still perfect. He also noted that she was now able to control her dreams at night, becoming a lucid dreamer. When she started high school, some of her realistic dreams were crushed, but her other dreams only grew stronger until they became more powerful than even nightmares. She seemed to almost scoff at the darkness when it tried to take over, easily changing a potential bad dream into a good one.

Sandy had to stop visiting her for almost an entire year because Pitch had tried to send nightmare after nightmare to try to combat her pure dreams. This was already years after the battle and he had thought that if he could gain her fear, he would be much stronger again. After Pitch gave up on her, Sandy still didn't visit Aisling much, though he could constantly feel her dreaming. It hurt him to know that while she believed in all manner of beings and had even believed in the existence of Santa Claus, the Easter Bunny, and the Tooth Fairy, she had not even given his existence a second thought.

The year the movie was released was a good year for the Guardians. They had all anticipated a boost in belief and were not disappointed. They were each stronger than ever. On the other side, Pitch was also more believed in and gained strength. It was Easter of her second year in high school when Aisling watched the movie. He knew it exactly because of the surge of power that burned through his veins. Her light on the globe was again bright and she had strong belief in the two lesser-known Guardians.

He visited her at night now and again, being extra careful to not reveal his presence. While the movie had spurned her belief in him, she had also believed in Pitch. Unconsciously, she had felt bad for him and had stopped turning the nightmares completely into good dreams. She would simply detach her strongest emotions from the dream and let only a slight piece of her fear flow through to give Pitch power. Sandy worried about this, but as Pitch made no irregular moves, decided to allow it.

Aisling continued dreaming even after she started college. Sandy had to visit even less because of her strange sleeping hours. It was now her third year in college and this is where the real story begins.
