Power of Rings

[Neithan]

Actually, I don't. Could you explain this? Thanks.

Basically what I was saying was that true mortals leave Arda entirely when they die but Dwarves do not. Dwarves stay in the Halls of Mandos until the end of the world. Elves are said to be "immortal" because they come back from the Halls. Men are mortals because they leave from those Halls to go wherever. Dwarves do neither of these things and that is what I was getting at. The fact that they (appearently) are not turned invisable by the Rings is probably due to the manner of their creation (the same reason that their fate is different).
