'Which is as Fate to all Things Else’

[Nilpaurion Felagund]

Well, in terms of Hroa, both Elves & Men are in the same position, so I can't see that Elves are more prone to fall to Morgoth's will than Men. In fact the sense I get is that elves are less likely to be decieved by Morgoth/Sauron than Men. When Elves fall it is seen as more out of the ordinary than when Men do. (davem)

[I]n Author's notes on Quendi and Eldar, HoME XI it is said that "no Elf of any kind ever sided with Morgoth of free will, though under torture or the stress of great fear, or deluded by lies, they might obey his commands" [ . . . ] (Raynor)

Sorry, I should have clarified myself. I didn't mean that they voluntary obey Morgoth's Will, rather that they are more swayed by the infiltration of Morgoth's power into marred Arda. Sharkû, apparently, has already thought of the same thing that I was trying to say (q.v.)

As I have mentioned once in chat, it is my belief that the nature of Arda being marred in, or even, as the incarnation of Morgoth, is an important reason for the Dwindling of the Quendi to be observed in the later Ages. The very fact that both exist make a connection likely, but there is also the further observation to be made that the fate of Elves is explicitly said to be tied to Arda and thus inevitably tainted by the incarnation of Morgoth, naturally so in the "mortal" lands and considerably less so, if hardly at all, in Aman.
