Well, I was when using some clues, it wouldn't seem near Aurora's lands and stuff, but then again magic XD

Another theory of mine is that using the number system of Jefferson's hat and guessing every world is present. If there are 17 doors in a circle the furthest away is either of two options. So, either 3 or 4, probably 4 is the EF door. It's a bit of a stretch, seeing that the merchant guy said he wished Cyrus as far as the Earth is from the sun, not as far as in a hat, lol.
