What is the importance of Middle-earth in the Unfinished Tales of Numenor and Middle-earth?

The tales in this collection are primarily set in Tolkien's fictional realm of Middle Earth. Middle Earth is a vast and detailed landscape that is brought alive through the rich details that Tolkien is known for. The land is made up of several distinct areas and terrains. The weather of a given area always fits both the landscape and the elevation. One of the most rewarding facets of reading Tolkien's work is that the details always match no matter which work is being read. The Middle Earth that is found in the Hobbit, is the same one that is found in The Lord of the Rings and in this collection.
