Lorelei
About
Lorelei was a witch who lived hundreds of years prior to the start of the story, and was Grand Witch Kalia's youngest sister. Skyla runs into her after being trapped in a time maze by a pair of mischievous fairies. Despite being an adult and a fully-realized witch, Lorelei has a childish and playful personality and dislikes when her sisters drop by to check on her.
She was prophesized as "the witch who will bring the end of the witches", which came true when she went against the witches' creed of not giving their hearts to anyone, falling in love with Grand Duke Antoine and meeting him in secret.
After Lorelei becomes pregnant with Antoine's child, she chooses to stay behind and not leave with the other witches.
