Ai! This is so beautiful! So fraught, so gentle, so poignant. And a really working of the prompts.

Ah, this was wonderful and touching! A great concept, too, Elros writing to the future Elrond. Whose children he has foreseen. <3

I love this. Elros is SUCH a character to me, and the way he talked about the uncertainty of death as a peredhel was an interesting and compelling look at it. 

  "Or perhaps you will one day, far in the future, when you sail into the west? Perhaps you will stop for a time on our island and see what my children and their children’s children have made of it. Oh, I hope that you will, and I hope that it will be as beautiful as I imagine it now."

Those lines are so painful, alas the Numenor fell! I really feel like, were they to be kept on Tol Eressea, it would be a comfort and a pain for Elrond to be confronted with these letters that are a loss of his brother, and of Numenor, whilst also dealing with the loss of Arwen, who also chose Elros' path, and the dream to rebuild a mighty kingdom which, like Numenor, may also fall terribly.

IDK this fic is bringing many thoughts!
