Thank you! I am glad you enjoyed this--despite some of the obscure conversation topics! (S vs Þ must surely have been the most self-indulgent, self-inserty linguistic detail Tolkien ever wrote...)

I guess, depending on how literally you interpret the Ainulindale, Miriel and Feanor might be wrong about the Valar's understanding of history/the world...but I think the elves must have had some doubts about that, at least among themselves.
