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 believed may be a threat to her family.
This led to her near sacrificing herself for her family in early 2018, when she consumed the entirety of a sleeping curse that had been meant for all the attendees at her parents Unwedding party event. Luckily, due to her heritage she was not killed but instead placed into a death-like slumber, her spirit separated from body. During this time she learned things, was able to help a couple of people, but when her family's enemy struck once again, she insisted on being brought back to her body. The process involved requiring the power of one of the first Six in order to fuse her soul back to her form, and the result was the fusing of the soul of the Brown to herself as well. This gave her the brown eye on her left side, and has given her a much deeper connection to Lauren, the girls basically soul-twins now.
