To reverse her immortality
After realizing what happened to her, Emmeline fled her life and used many aliases while befriending the Halliwell family multiple times, including Penny Halliwell, Patty Halliwell and Paige Matthews.
In the 21st century, Emmeline met up with Paige under pretense of wanting to catch up with an old friend and snuck up to the attic to read a spell in the Book of Shadows that brought her back in time in hopes of changing her destiny. Emmeline accused P. Baxter of being a witch and had cursed her, when it was really P. Russell who did it by accident; she was casting the immortality spell for herself when the young Emmeline was in vicinity.
The sisters followed her back in time and changed her fate, allowing her to live on as herself. P. Baxter left a message for her descendants that read, "She grew old."
Emmeline Graydon has appeared in a total of 1 non-canonical novel throughout the run of the franchise.
