It's a regular town, like Viridian, with an exit to the right, left, and another one downwards.
Add as many houses as possible, as some doors will be locked.
ok, also if you want while i was looking through advanced map to find the forset, and i was cleaning up (not done yet, stopped after finding the forest). Its kinda like a cove town? Ill make any changes to it if you want it.
