Don't you just love saying that? Mor-Dor, sounds a bit like Murder, it actually means Black Land or Land of Shadow in 2 of Tolkiens own created languages. (Btw, I highly recommend the Silmarillion to learn about the beginning of the LOTR world, including the mythology. I read this before I was interested in belief systems and comparative religion etc, so that says a lot!) That tower in the mist is pretty insane.
