A thousand years passed without note...
Long since did the fellowship of the ring part company in the Grey Havens. Gandalf, Frodo and Bilbo set sail with the high elves unto Valinor whilst the hobbits left behind returned home. Samwise Gamgee and Rosie, Pippin and Merry are now but distant a memory of the hobbit consciousness. The songs sung in the Green Dragon of the heroism and valour that saves Middle Earth from Sauron now long forgotten.
The king had indeed returned at the end of the third age and with him came once again order and a return to the pastoralist notions that Hobbits so welcome. The shadow had failed utterly at the end and it retreated behind the impenetrable passes of the east to gnaw on its defeat and brood for a millennia on revenge.
So what now of the Elves and Dwarves, Hobbits and Ents and Men and Orcs? Here is the story of the fall of all to the shadow that ended the fourth age of middle earth...but it is not the part of this story to tell of the intervening years through this age. Of the great, enduring peace and the swift rise of men to now take dominion over all others in middle earth. But in the end men faltered and waned despite the promise shown at the inception of all they created. So it is now as the world changes and once again a dread creeps into the forests and plains that the shadow has again returned does the story begin.
