Biography
After magic had extended Lobeilia's life for many years, she came to Olive's home to give her her birthright. The noise she made awoke Olive, who came outside to speak with her. Lobelia told Olive that she would have to choose between good and evil, and that the right path would involve many sacrifices. Before she passed on, she gave Olive a grimoire and a bridel to aid in her nightmares.
Lobelia's words stuck with Olive for many years, especially adding to her guilt over her twin sister Poppy's disappearance. (HOMEVID: White Witch of Devil's End)
