It seems like Chernabog is related to Emma's dark side or maybe even Snowing's dark secret during the preparation of the curse. I guess he's even woven more into OUAT mythology of the Sorcerer and the Hat. Maybe he's the Original Dark One?

Maybe some characters like Chernabog, Merlin, Blue Fairy, Black Fairy are the "original" creatures of the Fairytale Land?
