Death of the Nazgul

[Daniel Telcontar]

You forget, the nine was chained to the One. So if the One Ring was destroyed, so was any power that the nine rings had. Also with the three and the seven. The difference between the humans using the rings and the dwarves and elves, were their power to withstand.

The humans were easily corrupted into being Sauron's servants.
The dwarves were better to resist, and Sauron could not control the dwarves who wore them. That is why he took them back, because they had no effect. The elven rings also didn't corrupt their owner, because Sauron did not touch them. He could not corrupt them, and so he couldn't corrupt the bearers.

Lastly: Morgoth may be alive, but he is in the void. Another dimension with no doors to come back. He has absolutely no power in Middle Earth, and only Eru can bring him back, which I doubt he will. That means, shortly, that Morgoth is history.
