The West refers to the large region Middle-earth and includes the lands of Beleriand (up to the end of the First Age) Lindon, Eriador, Gondor, Rhovanion, and others, essentially all the lands west of Rhûn and Mordor. It is also used to describe the Free Peoples of Middle-earth like the Elves, Men, Dwarves, Hobbits and Ents particularly during the Third Age. West is normally 'the good' versus the bad from the East. (i.e. Sauron, Harad and Easterlings)
