You know, this is excellent, and so intriguiging! Perhaps for the Moriquendi there was a desire for their fëar to remain in Endor. It is so mystical, and poignant, and it seems quite possible, the more I think about it. Thankyou!

Creepy, but in a good way. I hardly ever see a writing about an Elf who doesnt heed the summon of Mandos and thus becomes the disembodied spirits. Of course there must be a lot of Sindar who refuse to go to mandos, why should they? This is their home and they don't know Mandos at all. And let's see... being imprisoned for Eru knows how long in a fortress whose keeper is a grim forbidding Being they don't recognize or keep wandering the green beauty of their home. Not so hard choice to make, isnt it? 

It's not so strange to think that the LACE about romance between elves too will be quite different in Middle Earth than in Aman.
