Actually, Camelot IS a part of the EF, as far as we know. When Lancelot celebrates the wedding of Snow and Charming, he says: "In my kingdom, there is legend of a cup that has the power to grant eternal life. And so may the love between you always be strong, true, and eternal."

He clearly designed Camelot with the word "kingdom", and we know when a character does that in the EF in the show, it is because it is a different part of the EF (cf Eric and the Maritime Kingdom)
