I think willkill has a good point, that maybe Eru saved the Faithful. That makes a lot of sense.
Amandil sleeping until the end of days makes sense too. I don't think that he would have shipwrecked.
Symestreem, you're talking about Eriol in the Book of Lost Tales. I think Tolkien abandoned all that though.
Short and Sweet. And I think I just completely changed my opinion.
