The Fellowship of the Ring (The Lord of the Rings, #1)

by J.R.R. Tolkien

Then all listened while Elrond in his clear voice spoke of Sauron and the Rings of Power, and their forging in the Second Age of the world long ago. A part of his tale was known to some there, but the full tale to none, and many eyes were turned to Elrond in fear and wonder as he told of the Elven-smiths of Eregion and their friendship with Moria, and their eagerness for knowledge, by which Sauron ensnared them. For in that time he was not yet evil to behold, and they received his aid and grew mighty in craft, whereas he learned all their secrets, and betrayed them, and forged secretly in the Mountain of Fire the One Ring to be their master. But Celebrimbor was aware of him, and hid the Three which he had made; and there was war, and the land was laid waste, and the gate of Moria was shut.
