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 by Men, but by Wizards, Witches, Elves, Dwarves, Hobbits, Fauns, Centaurs, Fairies, Mermaids and Unicorns including Griffins. Also by monsters like Dragons, Trolls, Goblins, Orcs, Werewolves, and Vampires including Ents and Giants.
Men, Elves, Dwarves and Hobbits resided in Middle-Earth. Men also resided in Darkland along with Fauns, Fairies and Centaurs. Giants lived in between mountains...
