This is just one of six new groups that are answers to "The Hero... *insert villain here*" groups. Any stories that show Twilight, princess or not, pulling an Anakin Skywalker (meaning she turns to the dark side, or is evil to begin with) are welcome.
Funny you should mention Anakin Skywalker, she's done that in the backstory to the currently most viewed story I wrote, which is based on Star Wars.
