I just found a sort of interesting article with a bunch of theories about the Phial of Galadriel, that she gives to Frodo upon their parting in Lothlorien. This author’s delving into all this stuff about the Silmarils, the 3 elven rings and other crap. It’s actually pretty interesting, to me that is. Also, there’s a page with an illustration/diagram explaining the idea. Apparently this author has a bunch of articles on this site.
