Middle-earth is the setting of much of J. R. R. Tolkien's legendarium. The term is equivalent to the term Midgard of Norse mythology, describing the human-inhabited world, i.e. the central continent of world of Tolkien's imagined mythological past. Tolkien's most widely read works, The Hobbit and The Lord of the Rings take place entirely in Middle-earth, and Middle-earth has also become a short-hand to refer to the legendarium or its "fictional-universe".
Within his stories, Tolkien translated the name "Middle-earth" as Endor (or sometimes Endórë) and Ennor in the Elvish languages Quenya and Sindarin respectively, sometimes referring only to the continent that the stories take place on, with another southern continent called the Dark Land.
Middle-earth is the central continent of Earth (Arda) in an imaginary period of the Earth's past (Tolkien placed the end of the Third Age at about 6,000 years before his own time), in the sense of a "secondary or sub-creational reality". Its general position is reminiscent of Europe, with the environs of the Shire intended to be reminiscent of England (more specifically, the West Midlands, with Hobbiton set at the same latitude as Oxford).
Lost and winter's on the way
And the air is craving in
And the streets are crumbling
But you are with me
Under the downtown city lights
We become statues without eyes
Barely audible
We're froze in time
I have you where i want you
Oh and i need to look away
When the jets are overhead
And the storm is closing in
Yeah something is happening
Beneath the modern cold high rise
We become statues without eyes
Stand at attention
They all align
I have you where i want you
Then it all aligns
It all aligns
I have you where i want you
We are statues withouht eyes
We were statues without eyes
