Thanks for the answers.
Nick, I was a bit slow on the uptake with this, but very true 😀
metcalph and mfbrandi, thanks for pointing me to Daroria. I had missed that. A follow-up question if you don't mind. From Daroria's entry in The Prosopaedia, "She has always been present, but humans did not perceive her until the late Second Age. She was revealed to be the divine power behind the lesser goddesses of Dara Happa". What happened?
