I agree with you, I think it's Gandalf because he was never "affected" by the ring.

You never know. It could be Bilbo because he's never been to Mordor, but I am probably wrong. [img]smilies/rolleyes.gif[/img]

I think it's Gandalf, but since Lomadia doesn't want to reply I'll post another one:
Boromir
Gollum
Androg
Isildur
Huor

Boromir,Isildur And Gollum all desired the Ring Of Power...
...so that kicks Angrod and Huor out...:D

Gollum is the only one who wasn't a trained warrior?

Pitchwife got the answer right, but not the reason. :)

Oh my god! I totally messed up the question! I just realised that I put Angrod instead of Androg! I am so sorry, guys!
Since I'm the one to blame for the incorrect answers, I feel I must give you a clue: if I add Grima to that list, Gollum will still be the correct answer. Just come up with the reason.

Gollum
Androg
Isildur
Huor
Boromir
Grima Wormtongue

Well, that's easy, then: it's the manner of their deaths. Gollum's the only one who wasn't shot.

Yes, you are correct, Nerwen!
