The Lord of the Rings

One Ring to rule them all, One Ring to find them, One Ring to bring them all and in the darkness bind them
In ancient times the Rings of Power were crafted by the Elven-smiths, and Sauron, the Dark Lord, forged the One Ring, filling it with his own power so that he could rule all others. But the One Ring was taken from him, and though he sought it throughout Middle-earth, it remained lost to him. After many ages it fell by chance into the hands of the hobbit Bilbo Baggins.
From Sauron's fastness in the Dark Tower of Mordor, his power spread far and wide. Sauron gathered all the Great Rings to him, but always he searched for the One Ring that would complete his dominion.
