§ Of the Rings of Power and the Third Age The Silmarillion

And so indeed it has since befallen: the One and the Seven and the Nine are destroyed; and the Three have passed away, and with them the Third Age is ended, and the Tales of the Eldar in Middle-earth draw to then-close. Those were the Fading Years, and in them the last flowering of the Elves east of the Sea came to its winter. In that time the Noldor walked still in the Hither Lands, mightiest and fairest of the children of the world, and their tongues were still heard by mortal ears. Many things of beauty and wonder remained on earth in that time, and many things also of evil and dread: Orcs there were and trolls and dragons and fell beasts, and strange creatures old and wise in the woods whose names are forgotten; Dwarves still laboured in the hills and wrought with patient craft works of metal and stone that none now can rival. But the Dominion of Men was preparing and all things were changing, until at last the Dark Lord arose in Mirkwood again.
