. . . based on what Tolkien says in Morgoth's Ring, that the Ring enabled
Sauron to tap into the taint of Morgoth in Arda. Sure, Sauron could
directly dominate those who wore the other Great Rings, but eventually he could
also dominate the shadows in the world, and the shadow within every living
being and every element in Middle-earth, shadows that arose because of Morgoth,
and will not disappear until Iluvatar himself intervenes and remakes
Arda. By making the Ring, Sauron hoped to become a new Dark Lord,
equivalent to Morgoth himself. Indeed, Sauron was bound to Morgoth by
terrible oaths, and if he had won presumably would have sought a way to rescue
Morgoth from the
void.
