Now I'm going to have to stalk you (off to friend you immediately). Hello! And isn't every fictional world borrowed from somewhere? Tolkien was a master borrower - the master of the master. I went searching through the Teutonic myths this summer and found him in the least likely places. Like Caedmon's fragmant of a poem (apparently, the oldest surviving Old English we've found). It gave me tingles:

Then the guardian of mankind, the eternal lord
the lord almighty, afterwards appointed the middle earth
the lands, for men.

And Rilke!! Yay. I'm going to have a chapter finished for you sometime this week. I hope you really don't mind the massive task of making me make sense.
