FAQ / Why did the elven Rings quit working when the One Ring was destroyed
Because Sauron was evil and made the OneRing so it was the most powerful and scariest of all of those rings of power. It was the ruling ring, right? Right. It has to do with creepy and unfair magical type things. The OneRing was made first. Sauron taught other people how to make rings of power. He wanted to use his OneRing to manipulate people with the other ones. It worked. Without the big ring in charge, the others wouldn't work. Sorry about that.
