Before I use it, I want to check if this is a good base:
i had a friend who had a besitary all about the world of ea, and it had this massive map of the enitre planet, and it showed that the "land under the wabves" was actually further north, and that the eriabor mountains was the souterhn half of the mountains in the old land (cant remember the bleeding name...ive got to reread the silmarilion)
it never mad emuch sense to me, but it was shown that it was further north original, so that the bay of forochel was actually just to the south east of where the landmass was....
also numenor is further north, between eriador and aman...its more central
