[daeron]

This thread is probably already present somewhere but I would like to know, if Beleriand was to NW of third age ME, how is Ered Luin to the east of Beleriand? Did Tolkien consider a spherical world as oppposed to the flat one? If Angbad was in the north, it being in the Mts of Eriador, doesn't that go higher. Anfauglith is also mentoned to the north

Also. what parts of ME were damaged in the War of Wrath and which during the fall of Numenor? Sil says that only northern regions were ruined in the War of Wrath.
