What happened to Sam?

[Orofacion of the Vanyar]

Did they live forever in the bliss of Valinor as did Huor...

That's Tuor, not his dad Huor.

What happens to the Ringbearers is completely up to your imagination. It is said that if mortals enter into Aman, they will die like moths blah blah blah. But then again, has any mortal ever made it to Aman and recounted it to anyone on Middle Earth? No. So really, no one knows for sure.

I like this fact. It leaves the question not only open for debate, which I'm sure will occur after I post this, but it leaves a certain mystery to Tolkien's work. If you know everything that happens within the realm of Arda, what fun will it be anymore. It's that same thinking that kept Tolkien from publishing an official "Silmarillion" by his own hand. Christopher did so, but the Professor was a bit more weary.

I read somewhere that Tolkien believed that the magic behind the LotR was the depth that was there, the unseen but obvious history that was at the foundation of the storyline. Tolkien said that once this history was revealed, the magic would fade slightly.

Ok I'm ranting alot so I will stop.

But basically to answer your question, it's up to you.
