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 in Middle-Earth. Some were friendly but most were not.The Giants feared the Belrog beast, Sorcerers and most of all Sauron the Dark Lord. The Ents were in Middle-Earth and Darkland. Unicorns could only be found in the blessed lands of Aman. The Vampires resided far south of Darkland in a cave of “The Yellow Mountains” that led underground also Werewolves had a small hidden village north in Darkland and in Middle-Earth and the Mermaids lived deep under the East Sea of “Mermaids Depths”. Griffins resided on a island called Numenor and they flew around all of Arda but did not enter the blessed lands of Aman. They have evolved from Eagles and mainly flew alone they were also hard to interact with.
The Gray Wizard and the Warlock resided in Middle-Earth.
Both of the Witches lived in Darkland. Goblins also lived in Darkland and in Middle-Earth with Orcs and Trolls.
Even tho the Mermaids lived under sea they also heard of Aragorn. Most of Arda knew of Aragorn now just as it knew of Gandalf. And once the Queen of Mermaids finally came face to face with Aragorn she vowed to have this handsome human warrior to herself.
Once again Aragorn, Legolas, Gimili, Gandalf and Frodo embarks on a dangerous quest to save the world.
