Dio sets off everyone's gay-dar, basically.

Fables is about fairytale characters in exile because the Adversary invaded their homelands. They settled on Terra Mundy, aka Earth. The largest congregation of Western Fables was in New York--Fabletown in exile. Cindy aka Cinderella is the resident spy and off the books agent. After reaching the new world some 200 years ago, she demanded a divorce from her cheating husband, Prince Charming. Somehow or other, she is recruited by Bigby Wolf, then Sheriff of Fabletown, to be the agent that does the messy jobs. So she's the go-to girl for assassination, hunting rogue Fables, spying on potential defectors and protecting Fable interests on Earth.

Being a member of Fabletown means she has signed the Compact--rule one of the compact is that they can't let the regular humans know about the Fables. Cindy does not know if Camp applies because the people aren't really regular humans. Fables are also very long-lived--it is implied that several centuries is not very old for a Fable. Cindy is also mostly immortal because bullets to the head won't kill her. Powerful Fables can heal and regenerate themselves, so while Cindy doesn't have any magic, she herself is possibly made of magic and human beliefs if not an alien from another world--I blame the writer for the Fables' dodgy origins.
