I like how there's almost a haunting aspect here, with Maglor's voice carrying on the wind, waking Nerdanel from bed...

I liked this line:

"But she knew him, her very own Makalaurë, left behind on the shores on the other side of Arda."

Both because it shows the relationship between them, and also because it's Maglor, not Nerdanel, who is being described as being left behind. I usually see the opposite, so this is an interesting change! 

This is thought-provoking, too. It makes me want more, to find out what each of them has been doing throughout the histories they lived through and aren't mentioned in.

I like the hopeful ending, as well!
