[Mithalwen]

I don't know I want to get deep into this because for me there are too many variants from the rings as written, in this hypothesis that one might as well say if it were a different book it would be a different book... however I so agree that you have to take the superlatives with a pinch of salt especially when referencing drafts and versions not published by JRRT. Some characters didn't appear til later. However regardless I think Luthien would have been useless aa a ringbearer because she is essrntially passive and only acts when motivated by the need to fulfil her own desire.
