Where on Middle earth am I?

[Hookbill the Goomba]

my 2 cents for what its worth

Well, It would be worth about 2 cents or 1.09651 pence here in Blighty.

I think that it’s possible that the first map was correct. After reading the first half of Silm today I realised that often the misty mountains, the anduin, and Kazad-Dum are mentioned. That would suggest to me that both the area of Middle Earth known in LotR and Belriand did co exist at one point. The ruin of Beleriand and the re shaping of the world from flat to spherical would may be hade rid the world of that area only. Or maybe I am wrong.
