[Galadriel55]

"the time Galadriel refers to, is Arda healed "
It is possible, Findegil. After all, many things are supposed to reunite when Arda will be remade (for example, the Silmarils). However, I've always thought that the healing of Arda is a process pretty much similar to fixing, let's say, a toy car. You take it apart, you clean all the little pieces and take out all the dirt that got stuck in it, but when you put it back together, it functions totally differently than it did before. I don't ean better - literally differently. What would the healing of Arda look like? I don't think that even the roles of different rces are going to remain the same.
"doesn't Treebeard himself regard it as a bit of Elven whimsy, rather than a prophecy" but don't elven profecies, even whimsies, eventually prove to be true?
