The fate of the rings [Spoilers] (Middle-earth: Shadow of War)

People in the know tell me. Developed like all the tails of this spinoff cleared, leaving only neponyatka our ring, because it is left of Sauron after he lopped off the fingers of the elf, and the true ending not a word about it, and in the books\movies not light.

So in summary: Sauron didn't use it and it lay there forgotten on the floor or waiting for another game where we are going to steal this ring off of Sauron.
