Micaela's mother Jane Jason nee Brighton, was a diviner who married a mortal man, Erick Jason. Soon after their marriage, Jane and Erick moved to London, England from Denmark. Jane didn't tell anything to Erik about her being a diviner so they continued on with their lives normally. After a year of marriage, Erik died in a car accident and unknowingly at that time, Jane was pregnant with a baby girl.
When Jane found out, she knew that the baby was going to be like her so she decided to move themselves back to Denmark. She settled themseleves in the outskirts of Copenhagen, the capital of Denmark. Five months later, on January 17, 1997 to a baby girl she named Micaela Kaye. To support her daughter and herself, Jane worked in a small sweets store near their house. The income was small but it was steady and there Jane found her second husband, Peter Peterson, a diviner. When Micaela was three years old, Peter and Jane got married.
Because of the marriage, Peter, Jane and Micaela moved to Vaerlose, Denmark a few miles away from Copenhagen. There, Jane became a full time mother to Micaela since Peter owned a large business. Micaela started developing her powers at the age of four and when she was eight, her mother and step father told her about her powers and that when she is old enough, she will be taken to Camp Crescent, a place that's for people like her. Micaela was very excited about going to Camp and she talked about it all the time.
When Micaela was ten, Jane and Peter pulled her out of school so that Jane could give her lessons on how to control her powers. Micaela enjoyed the time she spent with her mother learning about her powers. When Micaela turned sixteen, it was time for her to go to Camp, the moment where she waited anxiously since she was eight years old.
So a few months later, Micaela was driven to Camp by her parents and was welcomed into Camp by Astrid.
