I'm guessing past the town line will be obscured in mist. As for what is actually there, I think it will just be water, so basically Underbrooke will be like an island. That's my guess anyway, and would fit with the myths of the Underworld in that you get ferryed there by Charon (which appears to be how Emma and co. are getting there as well).
