SPOILERS: New Big Bad Coming to Bon Temps

Kristin at E! Online has some scoop on True Blood season 4’s new Big Bad, straight from Stephen Moyer:

Kate in Florida: Any dish on the upcoming season of True Blood?
Stephen Moyer spills, “We’ve got a new presence. There will be a new kind of specter that represents darkness. We had the wonderful Denis O’Hare as the king of Mississippi last year and he’s [gone] at the end of season three, so we’ve got something else coming in to replace that darkness, which is going to be really interesting, I think, this whole new sort of topic that we haven’t covered.”  Guesses on who the new “darkness” will be?

“Specter”? “Darkness”? Could this have something to do with the faeries?
