Lorelei was conceived during her mother's final year of school, while her parents were still in London for a month or so after her father's heart surgery. She became aware fairly early on, and when she realised that her mother was in danger from a stalker that had kidnapped Jezebel, she called out for whoever might be listening, which happened to be her great grandmother Lillian. While the Sorceress was able to make sure that Jez didn't die in the house that had burned and fallen around her, Jez wouldn't have the energy to both heal and continue carrying her child, and so Lorelei was transferred to the womb of a woman who lived on Isle du L'Arine.
There, she was born, and though loved by her 'parents', she felt no connection to them and had no desire to remain, despite the visits and lessons from Lillian. The people who believed they were her parents were not of her blood, and Lorelei had already chosen her path, and thus she ended up eventually leaving them with the assistance of Flora, who brought Lorelei to Tallygarunga one day, when the great pygmy puff prank was occurring. Lei found her way to her grandmother and, via Adele (once she was told of their relation), to her mother and father. Reunited once again, she felt content once more.
From there, the girl lived a relatively normal live for one such as she, who had a famous mother and an intelligent father. She was thrilled when she received siblings, and was continued to be visited by Flora - who she considered to be her best friend - as well as Lillian, who continued to impart knowledge and lessons upon the young girl. She became interested in non-humans and magical beasts from a very young age, and has spent a great deal of time learning more about them, while also keeping a cautious eye out for anything that she believes may be a threat to her family.
