I can’t find the thread now but in one thread it was speculated that Santa’s workshop is where you end up if you take the Straight Road north instead of west.
Wow, that page still exists? I haven’t seen or looked at that page in like, ten years. (And I’m even responsible for one of the entries there!) That particular one was the one I had in mind, too!
Hmm, well, I was going to posit that it was built completely independently of Sauron and well after the other Rings, but the Elven Rings were also “untouched” by him but were linked to the One by underlying principles of some kind. So it does stand to reason that Saruman’s “flattery” would have operated under similar principles and thus also fail.
Santa lives near Thangorodrom? He has elves (probably Noldo given how crafty they are) twisted into an almost unrecognizable form? He must be Morgoth, or some Maia in his service.
