Inhabitants of the undying lands: immortal?

[radagastly]

Welcome to the 'Downs, Blokdog!

Just being in the undying lands does not grant immortality. Even the Valar cannot undo the Gift of Iluvatar. I always got the impression that mortals in Valinor were granted the right to choose the time of their own death, like the kings of Numenor could. There is a quote, which I cannot find right now, that seems to imply that Frodo would have plenty of time to find healing and peace before passing beyond the circles of the world.

in the silmarillion to king tar-atanamir is said:”for it is not the land of manwë that makes its peoples deathless, but the deathless that dwell therein have hallowed the land”

The answer is in your own post.

Again, welcome to the Barrow Downs!
