It looks like either

a) Beacon, Forever Fall, and Emerald Forest are atop a cliff over the city.

b) There's a wall that separates Beacon, Forever Fall, and Emerald Forest from the city.

But given that Beacon has been displayed as being atop a cliff before, I'd guess that the correct answer is most likely A or a combination of A and B.
