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 によって Men, but によって Wizards, Witches, Elves, Dwarves, Hobbits, Fauns, Centaurs, Fairies, マーメイド and ユニコーン including Griffins. Also によって monsters like Dragons, Trolls, Goblins, Orcs, Werewolves, and ヴァンパイア including Ents and Giants.
