The Ring and the other races

[obloquy]

But the ring would no doubt offer the Ents back their Entwives.

Yes doubt. :P

There is no way the Entwives will just reappear, only logical reasoning is they are either extinct or just wondered away somewhere. However, the Ring would feed off the Ents desires of getting back the Entwives, so it would offer the Entwives back to the Ents, as a way of manipulation.

Manipulation to what end? Mischief?

The Ring didn't just offer whatever. Those affected by it envisioned themselves achieving greatness, or becoming mighty, or possessing/ruling something. I don't think it would have offered me a turkey sandwich unless there would be something to be gained by me desiring to claim it. My whole point was that it had designs and used its influence to further them, not just as an indiscriminate cry for attention.
