Not a problem, but a clarification: How much do various characters know/suspect of Gandalf’s true nature in LotR? It’s clear that the hobbits know jack, and many men think he is a powerful “wizard” (but still, basically, a man). Do the elves (and Aragorn) know that he is a Maia, or just suspect it, or did they not even look at things as rigidly as we, the readers do? (i.e., wizards are wizards, a category unto themselves, and we don’t have to shoe-horn them into a category like men, elves, maiar, etc.). Did Sauron even know Gandalf was in-country, or what his name/identity was? Did Sauron even know the major players arrayed against him at all (Aragorn, Elrond, Galadriel, Celeborn, Treebeard, Thranduil, etc.)? Or were they all just irritating insects, not worthy of his attention?

Faramir and Strider both have a good idea. Faramir even refers to him as Olorín.
Elrond, Galadriel and Cirdan of course have a very good idea. Galadriel probably knew of him in his other form. She always pushed Gandalf first in the council, ahead of Saruman if I recall correctly.
Glorfindel, probably knew as he very possibly came back on the same boat as Gandalf.
Sauron did not know much about Gandalf until near the end. Gandalf was always very careful not to reveal himself. However, Sauron must of learned much from Saruman that Saruman never meant to let slip. If this were true, then he would have been suspicious of Gandalf and his movements.
I do not have a good feel for what Treebeard guessed or knew, I suspect he did not realize that Gandalf and Sauraman were Maia.
Sauron knew who Thranduil was and had made war on him more than once, same for Galadriel. Elrond was probably a bit more of a mystery, hidden away in his valley, like a very pale shadow of Gondolin.
Sauron did not know of or suspect Aragorn until Aragorn revealed himself by wrench control of the Palantir away from Sauron. This still did not confirm what manner of powerful Chieftain Aragorn was, but he must of worried that he was a might Dunedain and had access to the Ring.
