Crystal Claw is a 2021 Daria fanfiction, by Sheila Wisz Ellayn.
This paranormal style story follows the events after two evil spirits invade the bodies of Quinn Morgendorffer and Stacy Rowe, which eventually causes profound and tragic changes in Lawndale.
Crystal Claw is probably the first story to give the backgrounder Happy Girl a protagonist role, as she becomes the best friend of dark spirit Ella Anne Morgendorffer. The story provides Happy Girl, under the name of Anna Felicia Coulthard, with magical powers and deep exploration of her background and life history.
As of April 2022, Crystal Claw is still in development.
