Or the elves may have been having a party for some other reason. Who knows.
And Aule, I think his name is spelled, when he made them they were specifically designed to resist Melkor/Morgoth's power, unlike humans and elves who were not. So naturally Sauron could not do anything to them with his rings.
Though I do wonder when he told the other valar if that maybe gave whatshername, the idea to make the ents.
I read somewhere that Tolkein put Galdalf the white and Sauron on about equal power level since I read he did answer someone's question in a letter if the 2 had fought who would have won and Tolkein said it would have been about 50/50 that Gandolf would win. And Gandalf the white not just since he was improved in rank from grey to white but when Illuvator sent Gandalf back he removed the restrictions that Manwe put on the istari when they first went to middle earth.
An interesting thing I read somewhere regarding the those ghost guys, forgot what they were called, that for that guy's curse on them to work Illuvator had to do that since he's the only one who could have kept them there as ghosts. The valor and maia can extend life, but do anything like that I read. not sure if it is true or not. Tolkein likely wasn't thinking about that when he write that. He may have just thought it would make a cool bit of a story and put it in.
