Middle-earth is the main continent of Earth (Arda) in an imaginary period of the Earth's past, ending with Third Age, about 6,000 years ago.

This (Arda) Universe is much different from Tolkien’s tale. Before Gandalf and Frodo take their leave to Aman, with the elves Gandalf senses the return of Sauron.
In this epic version (Arda) is peopled not only por Men, but por Wizards, Witches, Elves, Dwarves, Hobbits, Fauns, Centaurs, Fairies, sereias and unicórnios including Griffins. Also por monsters like Dragons, Trolls, Goblins, Orcs, Werewolves, and vampiros including Ents and Giants.
