I don't think the story is true. I have a feeling that Sauron is in the background whispering lies to Gil-galad and Celebrimbor, and he probably need the mithril to create the rings.yeah, I’m with you on that one. It can’t be anything as simple as mithril being extremely useful and they can make fantastically beautiful things with it. Some writer has to up the stakes and make it an existential necessity for the elves.
