I don't really agree with the idea myself, though I do see your line of thought. As I say everytime with this type of question...It maybe JRRs Middle-Earth, but it is your game and your story. All in all you have done a good jod keeping it "Tolkien", I just hope that I can as good with my online game, and the good Prof. s work will stand a little re-writting here and there. It is pretty much a given as, though his descriptions do put forth detail, they do so in a very minimal way. It is one of the things I have found interesting about his work...He puts forth volumes, in paragraphs.
Long story short;
Your game+your story=your world.
