So, according to the official twitter account of the show - twitter.com/lotronprime it appears that the series will be set in the Second Age. So, this thread is to explore the possible story lines that could take place. Will it focus on the forging of the rings, and Sauron's deception of Men and dwarves? Will it focus on the Last Alliance of Elves and Men? The fall of Númenor?
