How did Celeborn, Glorfindel and Beregond get their information ?

Very good post Puddleglum, but I am not sure that Galadriel's ring is the primary much less sole cause of her knowing Sauron's mind as it concerns elves. I am recalling Elrond confessing that to the Fellowship before it started out 'all under the shadow is dark'.

So perhaps this is her own innate power and skill. But the rings were involved and we know little about how much.

The ring slows down time to a more 'elvish' speed and elrond [?] during the council says that they have no offensive purpose.

I have always wondered about the differences between the 'boundary' of Lorien and the Girdle of Melian.

Lorien was more physically guarded; in Doriath one would become psychically confused [presumably till detected/captured].

But did Galadriel's ring do more than spook out most non-elves?
Galadriel also has control over the river-mists [see the ride of eorl UT] and Gandalf for one reason or another has a close relationship to fire, especially for preserving life and community [fireworks].
