Great stuff,
Gwath, I learned a lot from it.
It might already be long enough, but maybe you want to mention each Ring of Power had a stone set in it. I don't know enough about the details, but you might be able to uncover more if you look at the stones set in the three Elven Rings and see what symbols Tolkien is playing with.
Either way I think it's a strong paper, and it progresses smoothly too, it doesn't jump all around (a quality my papers tend to have
).
