While considering a recent question, I realized that I may not have fully understood something about the creation of the Rings of Power: were they (the 3, the 7, the 9, and even the lesser rings) at all connected before Sauron's One Ring "bound them" in darkness?
It seems like a very "Elven" thing to do, to allow Ringbearers to communicate and feel each other, but is that ever specifically stated? On the other hand, if they were already connected, what is the significance of the line "and in the darkness bind them"? Does it imply that the Rings could previously "disconnect" from each other, but now they were forced to accept Sauron's influence? Or were they never connected in the first place?
Once the One was created, its influence was clearly felt across all the others. But was that connection new, or did Sauron simply dominate a pre-existing connection between magic rings?
